(from Porsche Press Release) The second-generation Boxster range comes in a new, dynamic outfit in terms of both looks and technical features. In their design, the new models follow Porsche's usual process of steady and consistent evolution. Without being required or seeing any need to radically change the design and looks of the car, Porsche's designers have further refined the already very well-balanced and harmonious design language of the former model. The very nose of the car with its new headlight design, the silhouette of the new Boxster with its new, even more muscular contour of lines, the larger wheels, as well as the rear end with its new, even more striking joints and seams all look familiar and well-acquainted, but are nevertheless even clearer, firmer and more functional in style than before.
The new power in the
design of the Porsche Boxster continues appropriately within the
lightweight bodyshell of this outstanding mid-engined roadster:
Maximum output of the 2.7-litre Boxster is now 176 kW or 240 bhp, an
increase by 8 kW or 12 bhp. Maximum output of the 3.2-litre
six-cylinder in the Boxster S, in turn, is up from 191 kW or 260 bhp
to 206 kW or 280 bhp. Performance on the road has improved
accordingly, the Boxster now requiring a mere 6.2 seconds for the
standard sprint from 0 – 100 km/h and achieving a top speed of 256
km/h or 159 mph. The Boxster S, in turn, accelerates to 100 km/h in
5.5 seconds and has a top speed of 268 km/h or 166 mph.
The optimised five-speed gearshift on the Boxster offers the driver even shorter, crisper and more precise shift travel than before, plus improved synchromesh. The Boxster S comes with a new six-speed manual gearbox also featuring shorter gear travel and available as an option on the Boxster in conjunction with active suspension.
Wider track with active suspension as an option
Enhanced to an even
higher standard and with an increase in track between 24 and 35
millimetres (0.94 – 1.38"), larger wheels and new tyres, the
suspension allows even higher lateral acceleration with road comfort
remaining unchanged. The Boxster comes as standard on 17-inch wheels
(previously 16-inch), the Boxster S runs on wheels measuring 18
inches (previously 17 inches) in diameter. Porsche's new PASM Active
Suspension Management available as an option changes the damper
control map at the touch of a button, thus offering the best of two
worlds in one and the same system: The perfect combination of a
sporting and comfortable suspension, on the one hand, with an
extremely dynamic, performanceoriented set-up on the other, ensuring
a supreme standard also on the race track.
Sports Chrono Package for enhanced performance
The Porsche Sports Chrono Package is simply ideal for the sports-minded, truly dedicated driver. Offering modified engine control maps and management strategies for driving to the extreme with maximum safety and efficiency, this individual feature activated at the touch of a button comprises an analogue/digital stopwatch on the instrument panel enabling the driver to check the dynamic performance of his car down to the last hundredth of a second.
Driving dynamics improved to an even higher standard
Benefitting from the
mid-engine concept, the Boxster series now offers an even higher
standard of performance on the road ensured not only by the wider
track and larger wheels. In addition Porsche's development engineers
have reduced lift forces both front and rear and have minimised the
drag coefficient to a Cd rating of 0.29 on the Boxster and 0.30 on
the Boxster S.
The new rack-and-pinion steering with its variable transmission ratio guarantees outstanding agility on winding roads and, at the same time, excellent driving stability at very high speeds. And now the steering wheel is adjustable not only for reach, but also for height (by 40 millimetres or 1.57"), offering the driver an even more individual seating position.
Modified brakes – for the first time also available with ceramic brake discs
The brake system has also been upgraded to match the car's even higher standard of performance, now responding even more quickly thanks to the upgraded and even more effective brake servo. Diameter of the brake discs which are cross drilled and inner-vented on all models is 299 millimetres or 11.77" at the rear and 298 millimetres or 11.73" at the front on the Boxster as opposed to 318 millimetres or 12.52" at the front on the Boxster S.
Even larger (350 millimetres/13.78") but lighter discs are available as an option on the Boxster S coming for the first time with optional PCCB Porsche Ceramic Composite Brakes. Apart from their extra grip, these very special brakes are absolutely rust-proof and are subject to far less wear in regular driving conditions, while at the same time offering a very high and, in particular, consistent frictional coefficient.
Now fitted as standard, PSM Porsche Stability Management enhances active safety to an even higher level in applying the brakes, in accelerating, and in bends. As a result, this modified system allows an even more sporting and dynamic style of motoring with even more sensitive control.
The world's first roadster with a head airbag
The Porsche Boxster is the first roadster in the world to protect the driver and his passenger against collisions from the side by means of a head airbag. Combined with a thorax airbag housed on the outer side of the seat backrest, the airbag comes out of the doorsill whenever required and ensures a very high standard of safety around the head area also in an open car.
New interior with unique seats
The interior is also brand-new in design, enhanced ergonomically to an even higher standard. New materials in slush technology, leather and aluminium look create a very sophisticated, high-quality feel inside the car. The seats themselves are brand-new, offering the customer a choice of four different variants ranging from the standard seats through the electrically adjustable seats complete with a lumbar support and the leather sports seats all the way to the adaptive sports seats offering individual adjustment of the side supports on the seat bottom and backrest. Indeed, this range of seats is quite unique in the Boxster segment.
Cost of ownership reduced once again
Compared with the former models, the new Boxster and Boxster S offer even lower cost of ownership, with the cost of maintenance, fuel consumption and insurance, as well as road tax, down by 13 per cent. This calculation is based on a period of four years with annual mileage of 15,000 km or 9,300 miles, applying prices and rates in the German market.
Fresh Wind in the Roadster Segment
Eight years after its
first appearance, the Boxster is now entering its second generation
- and in the process it is becoming even more dynamic, more
sporting, more self-confident. Indeed, this is no surprise
considering that almost 80 per cent of all parts and components on
the new Boxster model series are new: Larger wheels and a wider
track clearly symbolise the increase in power and performance. The
2.7-litre six-cylinder featured in the Boxster now develops maximum
output of 176 kW (240 bhp), 8 kW (12 bhp) more than before. Maximum
output of the Boxster S, in turn, with engine capacity remaining
unchanged at 3.2 litres, is now up from 191 kW (260 bhp) to 206 kW
(280 bhp). Acceleration from 0 - 100 km/h in the Boxster now comes
in 6.2 seconds, the Boxster S completing the same exercise in 5.5
seconds. This extra power, combined with enhanced aerodynamics and
improved streamlining, provides a higher top speed on even less
fuel, the Boxster now reaching a maximum speed of 256 km/h or 159
mph on composite fuel consumption in the EU cycle of 9.6 litres/100
km premium plus (29.4 mpg Imp). Top speed of the Boxster S, by
comparison, is 268 km/h or 166 mph on average fuel consumption of
10.4 litres, equal to 27.1 mpg Imp. And it almost goes without
saying that both models outperform the EU4 and LEV II (USA) emission
This enhanced performance clearly means even more driving pleasure on the road. Not only the wider track up by 24 - 35 millimetres (0.94 - 1.38.") depending on the combination of wheels and tyres, but also the larger wheels on both the Boxster and Boxster S as well as the improvement of torsional and flexural stiffness, power steering with a variable transmission ratio, an even shorter and crisper gearshift, and, not least, all-new seats with enhanced side support all contribute to this improvement of driving pleasure. Active safety, in turn, is enhanced by an optimised brake system and PSM Porsche Stability Management now featured as standard and serving, inter alia, to re-stabilise the car on under- or oversteer by applying the brakes specifically on individual wheels and intervening in the engine management system.
The higher level of standard equipment - including, inter alia, larger wheels, PSM, air conditioning, a CD-radio, and an on-board computer - does not mean a higher price. On the contrary: Taking the level of equipment into account, the new models come at a price down by six per cent (Boxster S) and, respectively, even nine per cent (Boxster) versus their predecessors.
New face, familiar features
The new front end of the
Boxster clearly and proudly boasts that characteristic look of a
Porsche sports car, while at the same time retaining that typical
Boxster face. A characteristic feature is the new headlights concept
with separate main headlights and front light units complete with
integrated foglamps. Another significant sign of distinction versus
the former models is to be admired at the rear, the dividing line
between the rear panel and the actual body of the car no longer
running beneath, but rather above the rear light clusters. The new
models come with the same characteristic exhaust tailpipe in the
middle of the car already to be admired before and serving, again as
on the previous models, to distinguish between the "basic" and the
S-version: The Boxster comes with an oval tailpipe, the Boxster S
with round dual tailpipes. From the side, the larger wheels are
obviously a particular sign of distinction, the "basic" version now
running as standard on 17-inch wheels, the Boxster S being fitted
with 18-inch wheels in regular trim. And as an option three
different types of 19-inch wheels are available for both models in
Further signs of distinction are the larger air scoops up front of the rear axle and the new, protruding door handles. A further point is that all concave surfaces, for example on the door panel of the former model, have now been dropped. Instead, the side walls of the new Boxster "bulge" out clearly and proudly as a strong sign of power and performance. Yet a further change in design becomes clear as soon as you open the roof, the higher rollbar now flattened at the top being moved back a few centimetres to provide more space behind the seat backrests.
The new Boxster series,
already best-in-class, now comes with even more outstanding
aerodynamic qualities even though the frontal area of the car is
larger than before due to the wider wheel arches as well as the
larger and wider wheels: Drag coefficient is down on the "basic"
model from 0.31 to 0.29, with a corresponding improvement on the
Boxster S from 0.32 to 0.30. At the same time Porsche's development
engineers have been able to minimise lift forces on the front and
rear axles, giving this outstanding sports car safe and stable
driving behaviour even at very high speeds. Inter alia, this is
attributable to aerodynamic refinement both front and rear as well
as the redesigned rear spoiler moving up automatically at speed.
The underfloor of Porsche's new sports car is now fully covered, the area covered by panels beneath the car thus being enlarged by approximately 70 per cent. This helps to provide an even higher top speed and reduces fuel consumption in the high speed range. In particular, such improvements serve to give the car an even better balance above all at high speed, say on the Autobahn.
More Power for Both Boxsters
Ever since the initial
introduction of the Porsche Boxster in October 1996, the
six-cylinder power unit has been consistently developed step-by-step
for more power and torque. Originally introduced into the market
with engine displacement of 2.5 litres and maximum output of 204 bhp,
the "basic" engine was enlarged to 2.7 litres and maximum output of
220 bhp for the 2000 model year and supplemented by an S-model
delivering 252 bhp from 3.2 litres. Then, entering the 2003 model
year, engine output was increased once again to 228 and,
respectively, 260 bhp, with torque - perhaps even more importantly -
increasing consistently throughout the entire range for even
Developing the new generation of the Boxster, Porsche's engineers have once again significantly updated the car's engines: The Boxster now develops maximum output of 176 kW (240 bhp) from 2.7 litres, the Boxster S churns out 206 kW (280 bhp) from 3.2 litres. As a result, both models set a new standard in their power-to-weight ratio, the Boxster at 5.40 kg/bhp and the Boxster S at 4.80 kg/bhp. These two figures alone clearly describe how agile the Boxster responds to its driver's commands. Translating this superiority into the standard figures for acceleration and engine flexibility, the Boxster powered by its 2.7-litre engine accelerates from a standstill to 100 km/h in 6.2 seconds, while the Boxster S completes this exercise in 5.5 seconds. And should the driver press down the gas pedal in full in the secondhighest gear, the Boxster takes just 6.9 seconds to accelerate from 80 to 120 km/h, with the Boxster S handling the same requirement in exactly 6.8 seconds. A point to be considered in this context is that this compares the "basic" Boxster with five gears and the S-model with its six-speed gearbox featured as standard.
Operating in conjunction with twin-chamber intake pipes and a new, even larger exhaust system, the larger intake manifold serves to boost torque on both six-cylinder power units particularly at low engine speeds. This is done by closing a distributor flap in the intermediate pipe at low speeds in order to separate the two intake channels. The result of this separation is a significant improvement of torque, with much more thrust building up from just 1500 rpm.
The Boxster and, respectively, the Boxster S develop their maximum torque of 270 Newtonmetres (199 lb-ft) and, respectively, 320 Newton-metres (236 lb-ft) throughout a wide speed range from 4700 - 6000 rpm. And this increase in power and performance is not only easy to feel, but also pleasant to hear, with both engines now generating an even lower, muscular and more "throaty" rumble.
New six-speed gearbox in the Boxster S
The new Boxster comes with the former five-speed gearbox now upgraded to an even higher standard, while the Boxster S features an all-new gearbox with six gears. Gearshift operation has been improved to make shift travel a lot shorter and crisper than before, with shift travel down by approximately 15 per cent on the six-speed transmission and no less than 27 per cent on the five-speed gearbox. The big advantage for the driver is that he can shift gears quickly and precisely with a very good and direct feeling for the gearshift process. As an option both the Boxster and the Boxster S are available with five-speed Tiptronic S.
Even more sporting suspension with variable rack-and-pinion steering
Further enhancement of
driving dynamics was one of the most supreme objectives in
developing the suspension for the new Boxster generation. In this
process Porsche's development engineers took a very close look at
each and every detail, working consistently and thoroughly on the
overall set-up: Wider track, new combinations of larger wheels and
tyres, weight reduction on the individual components, and the
improvement of crash safety enhance the sporting performance of the
new Boxster to an even higher level, at the same time offering
greater safety reserves with driving comfort remaining just as
superior as in the past. And thanks to the better qualities and
all-round performance of the new generation of tyres, finally, the
new Boxster is able to efficiently convey a lot more power and
performance to the road.
As before, front suspension consists of a spring strut axle and separate arrangement of the longitudinal and transverse control arms - simply because this superior concept ensures very precise wheel guidance combined with superior roll comfort. The front axle subframe, in turn, has been re-developed for the Boxster, lighter but nevertheless stiffer aluminium swivel mounts ensuring far greater stiffness in the interest of enhanced steering precision and maximum lateral acceleration. Introducing the new generation of the Boxster, Porsche is giving its mid-engined sports car a hydraulically supported rack-and-pinion steering with variable steering transmission. The big advantage here is the combination of excellent agility particularly on winding roads and enhanced driving stability at very high speeds.
The McPherson rear axle concept typical of the Boxster has been further improved and upgraded for the new model series. The objective in redesigning the components of the rear axle was in particular to enhance lateral stiffness while at the same time reducing axle weight through consistent lightweight engineering. And the individual components of the axle have also been improved and upgraded in terms of stiffness.
Active suspension available as an option
Instead of the "regular"
suspension, the new Boxsters are also available as an option with
active suspension: PASM Porsche Active Suspension Management lowers
the entire car by 10 millimetres or approximately 0.4". And in the
2.7-litre Boxster PASM also comes as part of a sports package
comprising Porsche's sporting six-speed manual gearbox.
Porsche Active Suspension Management incorporates adaptive dampers with infinitely adjustable damper force, two accelerometers determining vertical movement of the car's body, as well as the PASM control unit. The purpose of this "intelligent" control system is to relate the signals emitted by the two accelerometers fitted on the damper domes front right and rear left to the car's lateral acceleration, steering angle, road speed, brake pressure, and engine torque. Then, applying this data provided through the CAN-bus, the system determines the optimum damper control map and adjusts damper response accordingly on each individual wheel.
In this process the driver is able to choose one of two suspension control programs via a button in the centre console: The Normal mode offers a more comfortable damper setting automatically switching over to an increasingly sporting mode as soon as the driver starts to push his car faster and more dynamically. The Sports mode, on the other hand, activates a harder damper control map for a particularly agile and dynamic style of motoring.
Incorporating a special unit referred to as the load change module, PASM serves to enhance active safety in both of these modes: When accelerating with full power, taking back the throttle and changing gears, the damper control maps are automatically adjusted individually on the front and rear axles. Under such conditions the dampers are briefly switched to a harder response in the Normal mode to prevent the car from "diving" excessively. In the Sports mode, by contrast, the system switches briefly to a softer damper curve whenever required in order to improve traction when accelerating, for example on bumpy surfaces.
The Sports Chrono Package for even more dynamic performance
Porsche's Sports Chrono
Package offers the Boxster driver an even higher standard of
sporting and dynamic performance in his - or her - car. The
particular features of this special package are the even steeper gas
pedal control map, a "harder" and even more abrupt cutoff function
at top engine speeds, as well as "harder" intervention by PSM
Porsche Stability Management now fitted as standard. And in
conjunction with PASM, the Sports Chrono program offers an even
harder damper set-up in the Sports mode.
To verify the advantages offered by this technology in terms of driving dynamics and to time the extra speed down to the last hundredth of a second, the Sports Chrono Package also features an analogue/digital stopwatch on top of the dashboard.
Larger brake discs - as an option even in ceramics
Reflecting the enhanced
power of the two engines, the exemplary brake system of the Porsche
Boxster has been modified on a number of significant counts: Now
brake discs measuring 299 millimetres or 11.77" in diameter ensure
optimum stopping power on the rear axles of both models, the brake
discs measuring 20 millimetres or 0.79" in thickness on the "basic"
model and 24 millimetres or 0.94" across on the Boxster S. Brake
disc diameter at the front is the same 298 millimetres or 11.73" as
before on the Boxster and 318 millimetres or 12.52" on the more
powerful Boxster S. All brake discs are now cross-drilled and
innervented in the interest of enhanced cooling. A sign of
distinction setting the two models apart from one another also
through their brakes is the black eloxy finish of the brake
callipers with four pistons each on the "basic" Boxster as opposed
to the somewhat larger, red-painted callipers on the Boxster S.
For the first time the Boxster S is now also available as an option with PCCB Porsche Ceramic Composite Brakes - an achievement in technology quite unique in this class. In conjunction with the brake linings also quite different in this case, the ceramic brake discs subject to far less wear and abrasion immediately build up a high and, in particular, consistent frictional coefficient during deceleration.
A world-first achievement: the first roadster with head airbags
Yet another innovation offered by the new Boxster comes in the area of passive safety: This is the first open car in the world to feature an innovative head airbag beneath the side-sills on each door. Together with the thorax airbags in the seat backrests, these new head airbags ensure a very high standard of safety in collisions from the side. This restraint system is rounded off by frontal airbags for the driver and passenger as well as three-point inertia-reel seat belts with belt latch tensioners and belt force limiters all fitted as standard.
Interior enhanced to an even higher standard
and improved in ergonomic terms, the interior features new materials
in "slush" technology and leather as well as trim components painted
in aluminium look providing unique flair and style. The lower
position of the seats, the steering wheel now also adjustable for
height, the pedals moved to the front, and the seats with longer
fore-and-aft adjustment are particularly beneficial to the tall
driver. A further advantage of the newly designed seats is the extra
space and greater side support they have to offer, the range of
seats available comprising no less than four different options:
First, there are the standard seats with electrical backrest
adjustment, then the enhanced seats complete with lumbar support and
electrical adjustment of all positions, the leather sports seats
with improved side support, and, finally, the new, adaptive sports
seats with individual adjustment of the side supports both at the
bottom and on the backrest. Indeed, this range of choice and
versatility is quite unique in the Boxster segment.
A further standard feature hardly requiring particular mention in this context is the electrically controlled roof which can now be opened or closed at speeds of up to 50 km/h or 31 mph. At a speed between 10 and 50 km/h, all the driver has to do is briefly tip the roof operation button to open or close the roof in a mere 12 seconds. Other features fitted as standard include electric window lifts, a CD radio, air conditioning with an integrated activated carbon filter, an on-board computer, and central locking. And last but not least, the Boxster S also comes with an alarm system.
As an alternative to the regular steering wheel, the Boxster is available not only with a sports steering wheel, but also - in conjunction with PCM Porsche Communication Management now comprising a DVD navigation module - with a multifunction steering wheel finished in particularly smooth and refined leather. Depending on the level of equipment in the car, this special steering wheel enables the driver to control important audio, navigation and telephone functions directly from six function buttons on the steering wheel - one example being the new BOSE Surround System specially tailored to the interior of the new Boxster and available as individual equipment. In this case no less than 11 loudspeakers and a seven-channel digital amplifier integrated in the digital MOST-bus provide an experience in sound setting a new standard in the roadster segment.
Low cost of ownership
Cost of ownership comprising the cost of maintenance, fuel and insurance as well as tax, without taking the possible loss of value into account, is down on the new model by no less than 13 per cent (based on German prices and rates). This calculation is based on a period of use of four years with average annual mileage of 15,000 kilometres or 9,300 miles. The maintenance and oil change intervals on the new Boxsters have been extended from 20,000 kilometres on the former generation to 30,000 kilometres or almost 19,000 miles. A further feature is that the air filter, benefitting from its far larger surface, now has to be replaced only after 60,000 kilometres and no longer after 20,000. This again saves the customer the need of going to the workshop and reduces the cost of regular maintenance by 21 per cent. Should the customer not accumulate the mileage required for regular maintenance, the car has to be serviced at the latest every two years.
