(from BMW Press Release) New milestones of automotive progress are set from time to time: Now, as the new BMW 7 Series approaches its market launch, it is that time again. As the world's most successful purveyor of premium motor vehicles, BMW now presents the 5th generation of its flagship sedan, demonstrating once again how all-encompassing luxury can be combined and harmonized with the pleasures of dynamic performance.
The new 7 Series will make its North American premiere at the Los Angeles International Autoshow in November, 2008 and is expected to be in U.S. authorized BMW centers by spring 2009.
Highlights.
Luxury and dynamics harmonize as never before: The new BMW 7 Series.
The new 7 embodies
luxury that inspires, driving dynamics that enthuse, and a visual
presence that earns universal admiration. It is the product of a
self-assured design philosophy and consistent yet ever-evolving
engineering artistry. In great measure, this new sedan owes its
unique, progressive character to an abundance of innovations whose
purpose is to make driving a magnificent automobile – as well as
riding in it – a memorable experience.
At the core of this experience are chassis engineering that sets new
international standards and all-new powertrain technology. BMW,
which introduced its Active Steering concept in 2004, now brings it
to the 7 Series in a new, unique form: Integral Active Steering,
encompassing not only the original variable-ratio front steering,
but also, new rear-wheel steering. Acting as an overall system, the
two capabilities deliver a new combination of handling ease,
maneuverability and unrivaled stability in dynamic driving
conditions: Integral Active Steering is included in the optional
Sport Package.
The new 7 Series introduces Driving Dynamics Control, which enables
the driver to select from four progressively sporty driving programs
with the touch of a button. Driving Dynamics Control integrates
Dynamic Damping Control (which has three-mode shock-absorber
control) with transmission shift characteristics, engine response to
the accelerator pedal, and steering assist and traction control
level.
Active Roll Stabilization another BMW advance in handling and riding
comfort, is yet another element of the available Sport Package: Via
electro-hydraulically actuated anti-roll bars, ARS reduces body
“roll” or lean in cornering to a minimum, greatly enhancing the
feeling of road-hugging handling.
An all-new engine that uniquely combines Efficiency and Dynamics.
Both U.S. models will be powered by an all-new twin-turbo V-8 engine also making its debut in the X6 Sports Activity Coupe. This is a highly advanced, unique and outstanding powerplant. With 4.4 liters of displacement and direct fuel injection (BMW’s High Precision Injection), the V-8 carries its two turbochargers in the “valley” between the two cylinder banks putting its exhaust valves inboard and intake valves outboard – a highly unusual layout and a complete departure from its predecessor. This “variation from the norm” pays off: the engine develops 400 hp over a range from 5500 to 6400 rpm, and a robust 450 lb-ft. of torque over the even broader range of 1750-4500 rpm. Compared to the like-named 750i/Li predecessors’ 4.8-liter naturally aspirated V-8’s 360 hp and 360 lb-ft., the new engine represents major progress in performance; and though official EPA ratings are not yet in, it is expected to deliver class-leading fuel efficiency as well. To provide some context to this achievement: the previous 7 Series’ 6.0-liter V-12 develops 438 hp and 444 lb-ft.
Leading the way again: a new generation of iDrive.
With the new 7, BMW
again assumes the role of world leader in automotive control
concepts. A 2nd generation of iDrive sets new standards for
ergonomics, efficiency and logical functionality with its larger,
higher-definition Control Display. New, uniformly structured menus
and an optimized control strategy for the display and
console-mounted controller are also signature features of the new
system.
Other new details include buttons for direct selection of the Radio,
CD, Navigation and Telecommunications menus, grouped conveniently
next to the controller. Visual assists and consistent flow in the
display simplify choices within the individual menus. In the GPS
Navigation section, users will benefit from map displays with new
standards of size, brilliance, detail and view choice. A “map
preview” function facilitates selection of the navigation
destination from a list; in a new operational logic, letters of the
alphabet and numerals are arranged in circular form for more
intuitive input of addresses and phone numbers.
For greater driving safety: Active
Blind Spot Detection
and BMW Night Vision with Pedestrian Detection.
Thanks to innovative
driver-assistance systems – some of them BMW-exclusive – active
safety also attains new levels. The new 7 is the first in its
segment to offer a Head-up Display, which projects relevant driving
information onto the windshield in front of the driver. The HUD is a
stand-alone option on U.S. models. Optional Adaptive Cruise Control,
with new Stop-and-Go capability, assists the driver in maintaining
serene progress in rapid freeway or interstate driving or on country
roads; and in dense, stop-and-go traffic, can do precisely that when
necessary to maintain a safe following distance.
With the new 7, BMW’s newly developed Active Blind Spot Detection
makes its debut. Its function is to warn the driver – by vibration
in the steering wheel plus a blinking LED on the exterior mirror –
upon initiating a lane change when there is an unseen vehicle in the
blind spot or when there is a vehicle –not yet in the blind spot-
but is closing in at a rate that could result in a collision if the
driver changed lanes. Active Blind Spot Detection will be offered
together with the Lane Departure Warning, a familiar BMW option but
new to the 7 Series. By alerting the driver (also, via a vibrating
steering wheel) when a lane change is initiated without the turn
signals, the driver is assisted in avoiding potential accidents.
Finally, the High Beam Assist, which automatically dims the
headlights for oncoming traffic and returns them to high beams when
the way is clear, is included with Active Blind Spot Detection and
Lane Departure Warning in the optional Driver Assistance Package for
U.S. models.
BMW Night Vision continues as an option in the new 7, and adds a new
capability: recognizing and indicating individual pedestrians on or
near the roadway.
Innovations in climate and entertainment systems – plus more space.
The new 7 delivers
technological progress in climate control and entertainment systems,
plus more space in the cabin to enjoy them. The standard automatic
climate control provides for precise adjustment of airflow and
temperature, free of drafts or unpleasant air turbulence. Newly
standard is 4-zone climate control, with which rear-seat passengers
can vary their climate independently on the left and right sides,
just as in the front compartment.
And speaking of the rear passenger compartment, the 750Li has a
140-mm/5.5-in. longer wheelbase for greater rear leg room; this
model also has more rear head room.
Sporty BMW image – in its most elegant form.
A harmonious blend of
dynamic presence and elegance is the overarching theme in the new 7
Series design. A long wheelbase (in the Li, longer), long hood and
short front overhang are basic attributes; a “greenhouse” set
relatively rearward, a flat roofline and overall dynamic proportions
say “BMW,” and at the same time “the most elegant BMW.”
At the front, headlights include BMW’s distinctive use of the
“corona rings” for Daytime Running Lamps, and are accented at the
top by a light band that visually unifies the traditional dual
headlights on each side. The BMW “kidney grilles” – another
traditional element, appearing here in new form – are notable for
their boldness, verticality and low placement.
In profile, the interplay of convex and concave surfaces associated
with recent BMW design appears here in extended, subtly swung
contours and lines. For the first time on a 7 Series, the front side
panels include a chromed “gill” that integrates the side blinker –
itself a safety element – and lends character to the relatively long
space between front wheelwell and windshield base. Form follows
function: this proportion is a consistent attribute of BMW body
design, and an outward sign of the rear-wheel drive and optimum
front/rear weight balance that are BMW tenets.
The profile’s sculptural modeling makes for a graceful transition
into the rear deck. Rooflines flow gracefully over the flanks all
the way to the bumpers creating a sporty conclusion to this
altogether graceful design. An understated chrome band connects the
taillight clusters, which continue the L-shape that has become a BMW
tradition. LED technology throughout makes for warm, homogeneous
illumination whether tail-, brake- or turn-signal lights or even the
3rd brakelight, set into the rear window’s upper edge.
Advanced, luxurious, inviting: the interior.
Generous space – it goes
almost without saying that occupants of the new 7 enjoy plenty of
knee, head and elbow room in the front and rear compartments.
Contemporary design – the ambiance is luxurious, high in quality and
advanced in its amenities and functions. The contours, color
coordination and choice of materials symbolize taste and harmony.
With its center stack lightly angled toward the driver, the control
center promotes the driver’s intuitive mastery of the vehicle: this
is always a hallmark of BMW interior design. And yet this interior
isn’t only for the driver; its concept, layout, technology and
design focus equally on the driver’s needs and the passengers’
well-being.
The feeling of generous space and harmonious design is enhanced by
horizontal color gradations pervading the entire cabin. High-quality
materials and meticulous workmanship communicate the innate
precision of these automobiles; details such as visible seams on the
dash and door ledges, and double-framed central air outlets, are
evidence of passionate devotion to details. The leatherette covering
the main instrument-panel surfaces has been newly developed to be as
close to leather as can be imagined – and yet soft Nappa leather
here and on the door ledges is optionally available.
As always in BMW, the harmony of design and function is visible
everywhere: for example, in the integration of door handles into the
door panels’ chrome trim lines, or the door pulls as part of their
contrasting trim material. Speaking of which: there are three
choices of wood trim, four Nappa-leather interior color schemes, and
the optional additional leather surfaces.
All these refinements and choices provide the interior counterpoint
to the 12 available exterior colors, and enable customers to
highlight classic elegance, sportiness or sheer luxury according to
their personal tastes and preferences.
BMW 750Li: lavish space for rear-seat passengers.
If the
standard-wheelbase 750i already offers generous interior space, the
long-wheelbase 750Li provides truly lavish accommodations for
rear-seat passengers. And in the new 7, the meaning of “L” isn’t
confined to just length: rather, this model also has its own
roofline This solution provides additional rear head room, as well
as help maintain the dynamic proportions of the car to avoid making
it look like a stretched version of the short wheel base 750i. Thus
BMW’s typical “Joy of Driving” is complemented by the “Joy of Being
Driven.”
And even this extra space can be further enhanced by two available
options. Rear Comfort Seats only available in the Li model, includes
individual left and right Comfort seats with multiple adjustments
including fore-aft (70 mm/2.76-in. range), cushion and backrest
angles, and head-restraint positions. Additionally, rear Comfort
Seats also feature Active Ventilation and Active Comfort (“massage”)
functions.
The Rear Entertainment Package adds yet another dimension to
rear-seat luxury: a DVD player with color monitors integrated into
the front seats’ backrests, controlled from a dedicated remote. This
option is available on both 750i and 750Li.
Clear, intuitive control concept for greater driving pleasure and comfort.
Control of the many
interior functions and amenities is via a freshly thought-out and
executed overall concept that is clear and intuitive. To begin with
the simplest aspect of this, ample storage is provided by a spacious
glove compartment, bins in the door panels and pockets on the
front-seat backrests. Two cupholders are on the front center
console; power-seat controls are on the seats and memory controls
are on the doors.
The basic concept for all controls rests upon a philosophy of a
clear, functionally logical arrangement of the entire interior.
Thus, driving-related functions are all on the driver’s side,
comfort-related functions around the center. This principle goes for
the placement of buttons, keys and levers around the cockpit, as
well as, controls on the steering wheel, where those for cruise
control are separated from those for the audio and phone systems.
Analogous to this “horizontal” division of functions is the
arrangement of all displays in a more “vertical” separation. In the
upper areas – and thus, at about the driver’s eye level – are the
primary displays, such as the speedometer and tachometer. Below that
are less frequently viewed instruments like the fuel and
oil-temperature gauges.
At a still lower level are actual controls, optimally accessible and
mostly operable without looking at them such as the turn-signal and
low/high-beam/flasher stalks. Controls that need to be seen to be
used are generally grouped together, for example, those for the
driver-assistance functions clustered around the main lighting
control: this too is highly logical, as all these support the
driver’s need to perceive the vehicle’s surroundings and situations.
Everything at a glance: instrument cluster in Black Panel technology.
The new 7’s instrument
cluster combines classic elements and new solutions into a complete,
harmonious presentation of driving information. For the first time
in a BMW, the entire cluster is a high-resolution Black Panel
display, in which four classic circular instruments are most
prominent; other driving-relevant displays and readouts – including
GPS Navigation, vehicle-monitoring functions, upcoming service
requirements and other information – also appear here in their
various (and function-related) graphic forms.
In “dormant” state, this display is a mostly blank black form
defined by its chrome-toned periphery and including only pointer
needles, scale markings and the tachometer’s red warning zone within
it. The circular instruments’ numerals, as well as, the integrated
displays for current fuel economy and range on remaining fuel, are
entirely electronic and not visible until a door is opened.
So it is that the advantages of mechanical and electronic displays
are ideally combined – with eye-catching visual and graphic effects.
As the user enters the vehicle, the circular instruments’ “chrome
rings,” until now open at the bottom, close and become brighter.
Once the ignition is activated (upon pressing the Start/Stop
button), the numerals plus all other displays and warnings
illuminate. As the engine starts, functions that have been
previously activated by the driver are then revealed as well.
The instrument cluster interacts in new ways with the iDrive control
display and the optional Head-up Display. According to selected
function, users can call up phone numbers or radio stations via the
steering-wheel controls. The cluster also augments the iDrive GPS
Navigation display with a further enhanced directional arrow
display, which can now direct the driver to change lanes and help
the driver find the correct street at a complicated or obscured
intersection. If the Head-up Display is activated, the relevant
directions appear primarily there; otherwise, they appear in the
instrument cluster.
Current climate-control settings are indicated in a second Black
Panel display in the center stack, along with all system controls.
Users need not go into iDrive for any climate settings.
E-Shift transmission selector and Dynamic Driving Control on console.
While retaining the
E-Shift concept first introduced on the predecessor – no mechanical
linkage from shift lever to transmission – the new 7 moves its
transmission selector from steering column to center console.
Instead of moving from position to position within a “gate,” the
E-Shift lever is generally “tipped” in one direction or another to
change from one range to another. Park is engaged by a button atop
the lever. To engage Reverse, the driver tips the lever forward; to
engage Drive it is tipped rearward. From Drive, the lever does
actually move to the left to engine its Sport mode; from there, the
driver can execute manual shifts by tipping the lever forward for
downshifts, rearward for upshifts. The lever markings are R-N-D in
the right plane and M/S -/+ in the left.
Adjacent to the E-Shift lever are the Driving Dynamics Control
selector (logically, on the driver’s side) and the iDrive
controller. DDC provides four settings that tailor vehicle
characteristics to different drivers, one driver’s different moods,
driving conditions – or all of the above. The settings are Comfort,
Normal, Sport and Sport Plus; the following vehicle-dynamics
parameters are affected:
Clearly, the vehicle’s
driving dynamics can be widely affected by these different
calibrations of so many elements. In addition, via iDrive, the
driver can program his or her preferences for all five parameters
into the Sport setting for a personal, instantly recallable mode.
Another control in this area affects Dynamic Stability Control
(BMW’s all-encompassing stability- and traction-control system)
alone. A brief push on this button switches the system to Dynamic
Traction Control, in which DSC’s intervention threshold is raised;
one effect of this setting is improved traction in deep snow. A long
push on the same button de-activates DSC altogether, though one
function (antilock braking) is always active.
Like its predecessor, the new 7 has an electrohydraulic parking
brake rather than the customary mechanical one; the driver sets and
releases the brake with a button on the console. An Auto Hold
function, which automatically holds the vehicle at a standstill and
thereby eliminates “creep” when stopped in gear, is also available
via an adjacent button.
iDrive, 2nd generation: more intuitive operation, expanded functions.
With iDrive, the
predecessor 7 Series initiated a new direction in the control of
vehicle features and functions; via a multi-menu color display and a
mouse-like controller usable by driver and passenger alike, a
potentially crowded landscape of buttons and knobs was supplanted by
a computer-logic control path. Now, a 2nd generation of iDrive
builds upon that pioneering development while making it more
natural, intuitive, simpler and elegant.
An overarching attribute of iDrive was the separation of control
(via the console controller) and display (the centrally placed
iDrive monitor). This basic arrangement remains; the controller has
been further developed and the display is larger: fully 10.2 in. vs.
8.8 in. previously.
Positioned at the same level as the instrument panel, the new
control display sets higher standards for logical, readily
understood menus and attractive graphics. The controller has been
refined for comfortable, intuitive selection and activation of
functions via standardized turn, push and tilt motions, while being
augmented with more direct-selection keys.
Convincing functionality, satisfying to use: controller with direct-selection keys.
Benefiting from the
newest biomechanics R&D, the state-of-the-art controller operates
with tactile precision and clearly structured motions. New control
elements, menu schemes and graphic representations in the control
display become evident upon first use, yet, user appreciation grows
over the longer term. A graphic depiction of the controller in the
display itself helps orient the user to the next control step; the
rotation, pressing and tipping motions generally correspond to those
of a computer mouse.
Thus interpreted, rotation of the controller takes the user through
menu selections; pressing it makes the choice. Tilting the
controller to the left or right effects navigation through various
menu levels. Via clear graphic organization in the form of stacked
layers and onscreen depiction of controller movements, the user
enjoys highly intuitive navigation. All menus are structured
according to a consistent scheme, so that one is almost immediately
at ease; menus are broad so that the user can view relatively
numerous options without switching to another level. Also, functions
are arranged so that in longer-term use the most important options
are reached more rapidly.
An additional new refinement is four direct-select keys placed
directly next to the controller, for the most frequently used menus.
These allow quick selection of CD, radio, phone and navigation
menus, and are augmented by three further keys of general utility:
one takes the user directly to the start menu (MENU), one to the
most recently active menu (BACK), and the third (OPTION) presents
various options within the current area. As a result, searches are
likely to be shorter, or unnecessary.
Familiar and proven, yet now more useful: Programmable Memory Keys.
An iDrive enhancement recently introduced in other BMW models now comes to the 7 and represents a further user convenience: Programmable Memory Keys. Lined up above the audio controls, these eight keys allow the user to store favorite or most frequently used functions (radio stations, phone numbers, navigation destinations as an example) on various keys and recall them instantly. The stored functions can be as specific and detailed as a navigation map in the preferred scale, an audio balance setting or a selected chapter in the Integrated Owner’s Manual (about which more later). And because the keys are sensitive not just to being pressed, but also to being merely touched by the user’s finger, one can get the stored function shown on the control display by lightly touching the key. If it’s the right one, the user need only press the key and it’s there, ready to use.
Large-format display, preview maps and full-screen images.
With its 10.2-in.
monitor, the new iDrive system doesn’t just outdo all other graphic
displays in automobiledom to date; its 1280 x 480-pixel resolution
means remarkably true-to-life images. It’s a system appropriate to
the vehicle it’s in, achieved via up-to-date hard- and software.
White-on-black menu lists; effective symbols and icons; contemporary
graphics; and clear, consistent color-coding are among the elements
that enhance, not only function, but also esthetics.
Menu structures, too, make finding desired functions easier. In the
Start Menu, all functional areas served by iDrive are listed.
Selecting a given item leads to its menu layer, where the options of
that level are also listed. This consistency in navigation assists
in orienting the user, as does the “stacking” of menu layers in the
display. Visual assists further contribute to clarity. And if the
user gets to a place where he or she didn’t mean to be, the Back key
usually reverses the error.
User-friendlier GPS Navigation.
This overall refinement
of functionality means simpler control of the standard GPS
Navigation. Full-screen map displays offer outstandingly detailed
views of the geography; maps and landmarks can be shown in
3-dimensional form. Selected points of interest along the travel
route appear with near-photographic realism.
Mere input of destinations reveals the new system’s impressive
capabilities. If the destination appears on a list in the system, a
preview map appears as the user scrolls the list; this can help
distinguish between places with similar or identical names. If a
destination (or a phone number) needs to be entered manually, this
is done with a new, circular “speller” that makes the entry go more
quickly.
Convenient combination of voice entry and controller operation.
Yet another iDrive
innovation is its ability to combine voice and controller entry,
called Multi-mode Input. The user can go back and forth between the
two methods while actually inputting; indeed, voice recognition can
remain active during input via controller and the user can modify an
input via voice. Voice recognition – BMW calls it Voice Command – is
activated by its function key on the steering wheel, and
de-activated either upon completion of the action or by pressing the
key again. Voice Command is simplified by visual display of the
available commands, yet its capabilities go further in that numerous
synonyms of these commands are also recognized.
This newly optimized iDrive introduces a very significant step
forward in the operation of automotive features and functions.
Greater efficiency, improved logic and clear, attractive displays
help define the character of the new 7 Series. Indeed, the new
iDrive helps the new 7 Series create a user experience that is
incomparable in automotive history.
Unique powerplant: the all-new new
twin-turbo V-8 engine
with High Precision direct fuel injection.
Previous BMW 7 Series
models of the same 750i/750Li designation were powered by a
4.8-liter, 360-hp V-8 engine – “naturally aspirated” in the tech
talk of engineers and car enthusiasts, meaning not super- or
turbocharged. That engine also had BMW’s Valvetronic system, in
which variable-lift intake valves assume the function normally done
by a throttle.
The new V-8 engine takes a different approach. Its displacement is
reduced to 4.4 liters; replacing – no, surpassing – the higher
displacement and Valvetronic are twin turbochargers and direct fuel
injection. In quantitative terms, the new engine delivers 400 hp (40
hp more) and does so over a range from 5500 to 6400 rpm, vs. the
previous engine’s 6300 rpm. Maximum torque is up even more: 450
lb-ft. vs. the previous 360, and available over the extremely broad
range of 1750 to 4500 rpm, vs. 3400 rpm before. The bottom line here
is, yes, greater power and torque; but more importantly, delivered
over a much wider range of operating conditions. Also impressive:
that 450-lb-ft. torque peak is almost identical to that of previous
760i/Li models’ 6.0-liter V-12 engine!
The point of the new engineering approach is to achieve higher
performance without correspondingly higher fuel consumption. In
technical terms, the approach involves some very new design details.
For the first time, twin turbochargers and the exhaust-cleansing
catalytic converters are placed between the V-8’s two cylinder
banks. In turn, this required the exhaust camshafts and valves to be
inboard so that the path from cylinders to turbochargers (which are
driven by exhaust gas) would be efficiently short. The intake
camshafts and valves are then positioned outboard. Visually, this
results in a very different-looking engine.
And an impressive-performing one. Aside from the dramatic thrust
that drivers will notice subjectively, the objective data are
dramatic as well: for the European 750i, 0-100 km/h (62 mph) in 5.2
sec. Data for U.S. models is not yet available.
Twin turbocharging delivers quick, sustained performance response.
As in the highly
acclaimed 3.0-liter 6-cylinder twin-turbo engine now available in
other BMW models, the use of twin turbochargers overcomes a historic
drawback of turbocharging: the so-called “turbo lag” before the
engine responds to the driver’s accelerator foot with strong thrust.
And the twin turbos keep delivering, over that wide rpm range
mentioned earlier. The effect is that of a significantly
larger-displacement engine; yet this aluminum V-8 weighs less than
such a larger, naturally aspirated engine of comparable performance
would.
Also, contributing to the brilliant performance is BMW’s High
Precision Injection, a system of direct fuel injection that sprays
the precise mixture of fuel and air directly into the cylinders,
rather than the intake ports.
Positioned centrally in the combustion changers for optimum
combustion, the injectors are thus subject to especially high
temperatures and must deliver the mixture at very high pressures. To
meet BMW’s ambitious performance/efficiency/emissions goals with the
necessary long-term durability, a “stack” of piezo crystals reacts
lightning-fast to impulses from the engine electronics, governing
the injector needle’s opening stroke and duration for ultra-precise
control. According to researchers who developed this technology, it
contributes 2-3% fuel savings and 20% fewer emissions.
Precise, responsive 6-speed automatic transmission.
BMW pioneered the
6-speed automatic transmission with the previous 7 Series; the new 7
evolves this concept with quicker, smoother shifting, improved
torque-converter efficiency and the new-type E-Shift driver
interface. Altogether, the evolutionary changes result in a more
responsive, more efficient and sportier transmission.
For example, when the driver “kicks down” the accelerator, the
transmission can downshift by as many as four gears – just as
quickly as if it were shifting down only one gear. And the torque
converter’s mechanical lockup – an efficiency-improving arrangement
– is now engaged more of the time reducing slippage and improving
throttle response, especially in the lower gears.
The new E-Shift driver interface described earlier in more detail
controls the transmission, not by mechanically connecting the lever
and transmission, but rather by electrical and electronic means. It
provides Normal, Sport and Manual modes, the last executed by the
driver “tipping” the lever forward for downshifts, rearward for
upshifts.
New, innovative chassis technology combines dynamics and comfort.
True to BMW tradition,
the new 7 exploits the creation of a new vehicle generation to
advance the art of chassis technology and engineering. Improving
both driving dynamics and riding comfort are always the core goals
of the transition to a new generation, and in these regards the new
7 upholds the tradition brilliantly.
Just as the new engine combines sporting performance with luxurious
refinement, all-around new suspension technology endows the new 7
with uniquely agile handling for a luxury automobile, yet also an
exceptional level of riding comfort. Beyond these “basics,” these
new cars allow the driver to decide at any time what priority to
assign to either of these attributes via the new Driving Dynamics
Control.
At the front, an all-new suspension system makes its debut. This
double-wishbone system, the first such system ever in a BMW
passenger car, marks a new step after BMW’s decades-long refinement
of the double-pivot strut-type suspension into one of the world’s
finest suspension systems. It is a multi-link type, adding an upper
link (“wishbone”) to the familiar double-pivot lower links and thus
relieving the strut of its role in determining suspension geometry.
The double-pivot lower arms make up the lower wishbone. Another BMW
specialty, the use of aluminum for links and other components, is
applied here too and enhances the suspension’s response and riding
comfort over rough road surfaces.
The rear suspension, too, is a significant evolution from its
predecessor. Like the new front suspension, it is a multi-link
system; BMW calls it the Integral system for its small, essentially
vertical Integral Link connecting the upper and lower lateral
control planes. And also as at the front, aluminum components are
extensively employed.
A complex multi-link system like this controls rear-wheel angles
very precisely, minimizing unwanted effects under load changes (such
as lifting off the accelerator while cornering, or hard acceleration
and braking) and achieving a comfortable, supple ride.
Though steel coil springs are used at the front and rear of the
750i, the long-wheelbase 750Li comes standard with electronically
controlled self-leveling air springs that compensate for loads
carried in the rear seat and trunk, maintaining normal vehicle
height even with a full complement of passengers and luggage.
Standard Dynamic Damping Control and Driving Dynamics Control.
Dynamic Damping Control
controls the shock absorbers to any level of firmness between their
softest and firmest settings, precisely adapting to road conditions
and the driver’s demands at any given moment. Ride firmness is
always at the optimum level for current road conditions, vehicle
speed and the load the vehicle is carrying (again, passengers and
luggage). On smooth roads, the shocks are kept at the softest
appropriate setting; in corners, they are instantly adjusted to a
firmer, just-right level. And when the vehicle encounters any
irregular road surface, they adjust to the optimum firmness level to
control ride motions, preserve riding comfort and maintain adhesion
to the road.
Dynamic Damping Control is standard on both models, developed to be
integrally combined with the also standard Driving Dynamics Control.
Driving Dynamics Control provides the driver choices of settings for
shock-absorber firmness, transmission shift characteristics,
engine-throttle response and power-steering assist: Comfort, Normal,
Sport and Sport Plus. In addition, the traction-and-stability system
Dynamic Stability Control continues with a Dynamic Traction Control
setting (reduced traction intervention) that improves start-up on
snow and is suitable for track-style driving.
Also standard on both models are 18-in. alloy wheels, carrying
all-season run-flat tires of 245/50R-18 dimensions. On U.S. models,
19-in. wheels and performance tires are available as part of the
optional Sport Package, or as a stand-alone option; two wheel
designs are available.
New, advanced option: Integral Active Steering.
In making its first
appearance on the 7 Series, BMW’s Active Steering (included in each
model’s Sport Package) also gains new capabilities. The familiar
front Active Steering electronically varies the steering ratio (the
number of degrees the steering wheel must be turned to achieve a 1?
steering angle at the front wheels) according to vehicle speed and
other driving conditions. At low speeds and in parking maneuvers
this ratio is decreased significantly, resulting in remarkable
maneuverability and agility; as vehicle speed increases, so does the
ratio, reaching a “normal” level at about 75 mph.
The 7 Series’ Integral Active Steering now also includes rear-wheel
steering capability. Via a steering spindle and an eccentrically
positioned servo motor, the rear wheels can be steered up to a
maximum of 3?. At low speeds, they are steered oppositely to the
front wheels; depending on vehicle speed, the turning circle can be
reduced by up to 27.5 inches – which, combined with the front
wheels’ reduced steering ratio, dramatically improves
maneuverability. Varying the rear-wheel steering according to
vehicle speed, the system steers them in the same direction as the
fronts at higher speeds, which enhances the more important attribute
of stability at these speed. A further, and perhaps less expected,
benefit is that the rear-wheel steering reduces the yaw rate in a
given road-speed maneuver, which would be perceived by rear-seat
passengers as an improvement in riding comfort.
As a result, this unique combination of Active Steering at the front
and rear wheels equally benefits both comfort and agility. Yet,
there’s even more: enhanced stability in braking. Linked with the
sensors of Dynamic Stability Control (DSC), Integral Active Steering
can also make a targeted steering correction to hinder any loss of
directional control under braking on a road surface that’s uneven
from one side to the other.
Secure handling via powerful brakes and comprehensive DSC functions.
Yet another
active-safety advance is found in the 7 Series’ newly designed disc
brakes. Four-wheel ventilated disc brakes are a long-standard
feature on all U.S. BMW models, but until now the additional
refinement of aluminum/cast-iron brake rotors has been reserved for
the highest-performing 5 and 6 Series models.
In this patented construction, the brake rotor (disc) consists of
two pieces: the high-carbon cast-iron outer portion, which functions
conventionally as the surface onto which the brake pads grip to slow
or stop the vehicle; and an aluminum “hat” in the center, which
mounts the rotor to the vehicle. The concept’s advantages include
reduced unsprung weight, complementing the aluminum suspension in
benefiting ride comfort and road adhesion.
Reduced rotor deformation under hard braking is the other benefit.
This means less tendency of the brakes to vibrate when hot, and
reduced likelihood of rotors cracking under extreme heat conditions.
The brake system is also supported by the comprehensive functions of
Dynamic Stability Control (DSC). These include antilock braking
(ABS), Automatic Stability Control (ASC), Cornering Brake Control
and Dynamic Brake Control; each of these functions contributes to
vehicle stability or to braking effectiveness. Other braking
enhancements via DSC include Brake Fade Compensation, which
compensates for loss of braking power (fading) under hard or
repeated brake use; Brake Standby, which snugs the brake pads up to
the rotors upon sharp acceleration to reduce the effective lag time
in applying the brakes; and Brake Drying, which brings the pads to
the rotors periodically during wet-weather driving.
Beyond these extensive functions, still others involve the use of
brakes to achieve desired operational and stability goals. For
example, a new Electronic Limited-slip Differential function comes
into play in vigorous driving when DSC is completely de-activated.
By appropriate application of only the rear brakes while cornering,
DSC simulates a traditional mechanical limited-slip differential.
This has the effect of better apportioning power between the two
rear wheels and thus improving traction in this driving situation.
(Which, like use of the Sport Plus mode, is not recommended on
public roads; it’s more of a racetrack or driving-school exercise.)
Intelligent driving dynamics via Integrated Chassis Management and FlexRay.
All such
driving-dynamics functions are coordinated and overseen by BMW’s
Integrated Chassis Management. Via sensing and analysis of a
multitude of inputs, this powerful electronic control scheme applies
and governs the interaction of these functions to ensure maximum
stability. Under rapidly changing conditions, such as changing road
surface, spontaneous steering input, abrupt acceleration or sudden
braking, ICM reacts with ultra-quick and ultra-precise interventions
via the DSC actuators, Dynamic Damping Control, and – where present
– Integral Active Steering and Active Roll Stabilization.
For this extremely sensitive and powerful networking of functions,
the new 7 Series employs FlexRay data-transmission technology.
Developed by a consortium of which BMW is a leading member, FlexRay
achieves heretofore unheard-of communication speed, some 20 times
that previously possible. In the 7 Series, up to 16 electronic
control units can be networked; in no other current automobile can
longitudinal, lateral and vertical vehicle motions be so precisely
monitored and influenced. BMW is the first motor-vehicle
manufacturer to offer FlexRay technology in production vehicles; it
appeared first in the current X5, and is also employed in the X6.
Intelligent Lightweight Design means maximum agility, efficiency and solidity.
Thanks to BMW’s
Intelligent Lightweight design process, the body structure of the
new 7 Series benefits from both weight efficiency and solidity.
Targeted applications of higher- and highest-strength steels, as
well as, aluminum for numerous elements and components allowed BMW
to achieve greater passive safety, yet reduce the structure’s
weight. Compared to the predecessor’s body shell, the new models are
approximately 20% more rigid in torsion – which, in turn, positively
influences driving dynamics. Expressed another way, the so-called
“lightweight index,” which quantifies torsional rigidity relative to
the vehicle footprint and weight, has been improved significantly.
Novel in the 7 Series’ market segment is its brand-new combination
of a steel main structure and aluminum roof: The light-metal roof
saves approximately 7 kg/15 lb., and because this savings is at the
vehicle’s highest point, lowers the center of gravity and further
contributes to vehicle dynamics. The doors are also aluminum, saving
a further 48.5 lb. As on the predecessor, the hood and front fenders
are also aluminum, making for a significant contribution to these
automobiles’ overall weight efficiency.
Outstanding occupant protection at all seating positions.
Robust structural
elements, extensive and precisely defined deformation zones, and
highly efficient restraint systems coordinated by the powerful
control electronics form the basis for the high level of occupant
protection in the new 7. Consequently, these vehicles are well
positioned to achieve excellent ratings in all crash-safety tests
worldwide. Impact forces are transmitted along defined paths in the
floor, side, bulkhead structures and roof into deformation zones
that hinder or prevent them from reaching the passenger cell. For
the structures that serve as these force paths, multi-phase steels
as well as a new generation of heat-formed steels have been
introduced, further contributing to the structure’s weight
efficiency.
Complementing the structural excellence are standard front-impact
and side-impact (pelvis/thorax) airbags, as well as, a curtain-type
Head Protection System. 3-point safety belts are provided at all
five seating positions, all of them with force limiters and the
front ones with electric pretensioners. For whiplash protection,
Active head restraints are standard on both front seats. LATCH
attachments (Lower Anchors and Tethers for Children) provide for
securing a child restraint seat at each outboard passenger-seating
position. All restraint systems are controlled by a central
electronic control module that evaluates collision type and severity
and activates them accordingly.
BMW pioneered Adaptive brakelights, whose lighting intensity
increases when vehicle deceleration exceeds a certain level and thus
warns following drivers that the BMW ahead is braking hard. Since
their introduction by BMW, similar systems have been introduced
elsewhere.
Extensive array of features enhancing forward illumination and outward vision.
It probably goes without
saying that Xenon headlights are standard on the new 7; but these
are just the beginning of an extensive array of advanced, beneficial
and enjoyable features that enhance these cars’ forward
illumination.
For example, the luminous “Corona Rings” that have become a BMW
identifier in recent years are now utilized for the Daytime Running
Lamps, adding visual distinction to a safety precaution favored by
many drivers. Adaptive control swivels the headlights according to
steering input, yaw rate and vehicle speed to aid forward
illumination around curves; and for the first time, the lights’
auto-leveling takes into account road topography (such as hill
crests, tunnels, steep ramps) and adjusts their aim up or down as
appropriate to avoid blinding oncoming drivers. At low speeds,
cornering lights help the driver “see around” city corners; for
backing up, on U.S. models both cornering lights (left and right)
illuminate.
World premiere: BMW Night Vision with enhanced recognition.
Via an infrared camera, the optional Night Vision scans a range up to 1600 ft. ahead of the vehicle over a 24-degree-wide range. Another first for the new 7 is this additional capability: recognition of the direction a pedestrian near the roadway is moving. If it’s parallel to the road, the system senses and displays the presence on the iDrive screen (or, if present, Head-up Display) but doesn’t warn the driver; if the person is on a path to cross the road, it does display a warning.
Cruise control with braking ability standard; Adaptive Cruise Control optional.
The 7 Series’ standard
cruise control adds new functions. One is the ability to apply the
brakes to maintain the set speed on longer downhill stretches;
another is continuously monitoring the vehicle’s lateral
acceleration and adjusting the speed if rounding a curve would upset
passenger comfort.
Adaptive Cruise Control is optional; in addition to the
speed-maintaining, acceleration and deceleration functions of the
standard cruise control, ACC can adjust the BMW driver’s speed
according to traffic conditions via radar sensors at the front of
the vehicle. Like the standard cruise control, the new 7’s ACC adds
a new capability.
One of these is Stop-and-Go, which can bring the vehicle to a
complete stop if traffic calls for it. After a stop of more than 3
seconds, the driver must step on the accelerator or select Resume to
accelerate back to the set speed or whatever speed the radar sensors
allow.
Driver Assistance Package: three further enhancements of outward vision.
U.S. models of the new 7
offer three safety-enhancing features in the optional Driver
Assistance Package. One of them, Active Blind Spot Detection, is new
to BMW; the other two have become available in other BMW vehicles
recently. All are new to the 7 Series.
Employing a camera near the interior rearview mirror, Lane Departure
Warning monitors road lane markings. When switched on, anytime the
vehicle begins to move across a lane marking without the turn
signals activated, this system vibrates the steering wheel. If the
driver does activate the signals, LDW does not react.
With the new Active Blind Spot Detection, radar sensors at the rear
of the vehicle monitor traffic in adjacent lanes taking in an area
from the driver’s blind spot rearward 60 meters/almost 200 ft. An
illuminated triangular warning LED appears in the exterior mirror if
there is a vehicle in this critical area. If the driver activates
the turn signal, the LED blinks and, as with Lane Departure Warning,
the steering wheel vibrates to warn the driver not to make a lane
change.
High Beam Assist is the Package’s third feature. Controlled by a
sensor on the interior rearview mirror’s forward side, switches
automatically between low and high beams. With this function, the
driver need not switch between low and high beams manually, thus,
removing a distraction. The high beams are likely to be used more
often; and other drivers and pedestrians are less likely to be
blinded by high beams inadvertently left on.
Hard drive for audio and navigation systems.
The new 7 comes standard
with a 40-GB hard drive, which provides fast access to navigation
data and space for approximately 13GB allocated to music storage.
Music data from a CD, MP3 player or USB stick can be transferred to
the hard drive then accessed at will. Via iDrive, users can enjoy
programming from a personal music collection, directly from a CD or
other external player, or the radio. Individual music pieces
(“songs”) are listed alphabetically by their title and performer,
and thus, easily located.
The standard audio system includes a DVD player and auxiliary audio
input. Available options include a Premium Sound Package consisting
of upgraded amplification and speakers, 6-disc DVD changer and iPod/USB
adapter. The available Sirius Satellite Radio option includes a
1-year subscription to the service. HD Radio with Multicasting,
which BMW pioneered as an automotive audio option is standard in the
new 7 Series. Two DAB (Digital Audio Broadcasting) tuners provide
not only enhanced FM and AM sound, but also allow a given station’s
audio program and traffic advisories to be received. Should the
vehicle leave the station’s digital broadcast area, the system
automatically reverts to the same station’s conventional
broadcasting.
An also optional Rear Entertainment System provides two 8-in.
screens integrated into the front seats’ head restraints. The system
is capable of reading a DVD either from its DVD player or the DVD
changer included in the optional Premium Sound System. The system
allows for 1 internal input, 1 internal + 1 external input or 2
external inputs (such as a game console). The result is that each
rear passenger has complete control over their respective screens.
Navigation system: standard, and incorporating the highest technology level.
Standard in the new 7 is
a newly developed and optimized GPS Navigation system with
high-resolution 10.2-in. monitor (this is also the iDrive control
display), dramatic 3-dimensional map views and a host of functional
innovations. The system is impressive, not just for its beautiful
screens, but also for user-friendly, intuitive operation. Displays
that include a graphic representation of the controller itself make
selection and activation of functions easier. Split-screen displays
give route directions left and preview maps right; in addition to
routes and destination, traffic information on the route is also
delivered. Especially impressive are the full-screen views of the
large monitor making it possible to view fine details of the map. A
help screen is available for further information.
The special map perspective provided in the Highlight Traffic
Conditions option offers additional convenience with current
congestion reports presented as road sections marked red. This can
be highly useful and time-saving, equally in urban, suburban and
Interstate or freeway driving.
The GPS guidance has been enhances with 3-D topographical and
mapping plus a more detailed directional arrow display.
the high resolution screen combined with the 3-dimensional views
make using the new navigation system a unique experience.
Topographical map views add value to route guidance through
mountainous or hilly country. At smaller map scales, say up to 25
m/82 ft., 3D representations of actual buildings improve user
orientation, especially in urban areas. In a more rural landscape,
notable buildings or points of interest are easier to find, and
easier to determine if such a point is coming up soon and if it’s
worth a stop.
The directional arrow display now provides a detail view of the
upcoming direction point and is able to direct the proper lane to be
in and exactly when the driver should turn (especially in
complicated intersections) – from the control display directly into
the instrument cluster or, if equipped, Head-up Display.
4-zone automatic climate control: optimum comfort for all occupants.
The previous 7 Series
already included many premium features in its automatic
climate-control system, such as dual-zone controls for the front
compartment, automatic recirculation, automatic ventilation to use
when the vehicle is left standing in the sun, heat-at-rest providing
heating for several minutes after the engine is shut off, and
temperature/volume-controlled air for the rear seating compartment.
Yet, here too, BMW has not simply rested on existing excellence:
U.S. models of the new 7 Series come standard with 4-zone climate
control, which provides individual left/right control of temperature
and air volume just as in the front. The 4-zone system adds a rear
control panel, plus an electric heater in the rear footwells; the
front center-of-dash air outlets are volume-adjustable from a gentle
breeze up to vigorous air delivery.
Rear seats with Active Ventilation and Active Support.
Available for the long-wheelbase 750Li model is a Rear Comfort Seats option consisting of multi-adjustable rear Comfort seats with Active Ventilation and Active Support, the latter being a “massage” feature. Multiple internal fans gently direct cooling air through special perforated leather on the seat cushions and backrests. Multiple internal bladders create a gentle, virtually imperceptible motion in the seating surfaces to help relax thorax, shoulder and lumbar regions promoting comfort and helping prevent cramps on longer journeys.
Effective and elegant lighting, innovative Contour Moonroof.
Elegant light bars set
accents on the new 7’s door handles, door panels and storage
pockets. U.S. models add as standard equipment a new way of
distributing ambiance lighting, whose rays are “broken” by a prism
structure to bathe certain interior surfaces with a subtle glow.
This harmonious illumination not only helps occupants orient
themselves in the cabin at night, but also enhances the interior’s
high-quality character.
An esthetic subtlety is delivered by a new moonroof design, standard
on U.S. models. Its 60 x 92-cm (23.6 x 36.2-in.) glass area makes
the interior feel brighter and roomier; its front edge is curved
parallel to the roof’s front edge for an unusual design touch.
Functional improvements figure in this concept, too: a powered
interior shade replaces the former manual one, obviating the need
for a handgrip recess. And the forward wind deflector rises to
different height positions on the basis of vehicle speed, more
effectively taming potential low-speed air drumming or high-speed
wind noise.
All-seeing: Park Distance Control, rearview camera and sideview camera.
Park Distance Control,
BMW’s ultrasonic-based parking assist system, remains standard as
the 7 moves into its new generation. PDC warns the driver via beep
tones when the vehicle approaches obstacles, at the front or rear,
which may be unseen.
New, however, are both a rear-view and a side-view camera to further
assist parking and maneuvering convenience and safety. Both are
included in the optional Camera Package. The rearview camera
transmits a high-resolution image to the iDrive control display,
plus –
The side-view camera
consists of two further cameras, one each in the front bumper’s
corners, which transmit views toward the sides to the control
display. This feature resolves that troublesome situation when one
is emerging from, say, an alley or garage exit onto a busy street by
giving the driver an “advance” view of traffic – and helping to
avoid an accident.
Both of these camera systems are de-activated at normal driving
speeds.
World’s first Integrated Owner’s Manual.
The amazing spectrum of
new features, technologies and capabilities offered by the new 7
Series is rounded out by yet another first: the Integrated Owner’s
Manual.
Analogous to the Help functions of today’s computers, BMW now
delivers the owner’s manual electronically, via iDrive. In just
seconds, the user can access information on virtually any detail of
the vehicle’s equipment, systems, operation, etc…like a traditional
owner’s manual, only better. Subjects are presented in a multimedia
format of animations, slide shows with sound and written
description.
In another new-age, highly desirable departure from the traditional
owner’s manual, the IOM is vehicle-specific; that is, the version
that goes with each new 7 Series vehicle corresponds to that exact
vehicle with its specific model designation and options. Various
information paths – brief instructions, picture search, keyword and
context searches – are available to the user. The user can also
store specific subjects on the Programmable Memory Keys. In
addition, the IOM can be updated as appropriate via the BMW center.
