Release) Lexus IS F High-Performance Sedan Provides
Stimulating Driving Dynamics
Suspension Provides More Driver Confidence
• Updated Electronic Power Steering Gives Driver Additional
• Torsen® Rear Differential Helps Provide Additional Traction
As the first production
model to wear the brand's "F" marquee, the Lexus IS F offers a
thrilling, fun-to-drive experience. The Lexus IS F high-performance
sport sedan races into 2011 with several interior updates including
LED daytime running lamps, an improved suspension, and a new brake
To improve responsiveness and ride comfort, in addition to providing
the driver with more control, engineers revised the Electric Power
Steering (EPS) system and suspension. With revised front and rear
spring rates, shock absorber dampening, rear bushings and rear
camber angle, the IS F provides a confident ride.
The sporty interior is complemented with new IP gauges, a silver
colored-trimmed steering wheel, and dark finish aluminum composite
ornamentation. The Sport mode switch has also been moved to the
steering wheel for easier access.
In addition, vehicles with a Black interior receive Alcantara® seat
inserts with leather bolsters that enhance its exhilarating
sportiness. An all-new Orange and Black leather interior with
contrast stitching flaunts the IS F’s vivacious attitude and
replaces the Terra Cotta interior.
The Lexus IS F is
exclusively powered by a performance-tuned 5.0-liter V8 engine
teamed to an eight-speed Sport Direct Shift transmission. The IS F
engine produces 416 horsepower at 6,600 rpm and 371 lb.-ft. of peak
torque at 5,200 rpm. The engine's high specific output (83.2
hp/liter) and high operating range (6,800 rpm redline) reflect the
thorough attention to detail underlying the core engineering. The
resulting performance character, while quite responsive in low-speed
situations, provides a rush of power at higher engine speeds.
The forged crankshaft features journals polished to a mirror finish
to minimize the friction generated between the connecting rods and
the crankshaft. Forged sintered iron alloy connecting rods ensure
high-rpm durability. High-flow cylinder heads designed by Yamaha
have a lightweight valvetrain, including forged cam lobes on hollow,
chain-driven camshafts, with the inside of the shafts serving as oil
passages. Titanium intake valves are operated by roller rocker arms.
Innovative technologies help to maximize efficiency and reduce
emissions, including the SFI D-4 fuel injection (direct-to-cylinder
injection system with secondary port injectors) and the Electronic
Throttle Control System with intelligence (ETCS-i). Essentially, SFI
D-4 integrates two types of fuel injection: A direct-type
high-pressure fuel injection system, which provides a cooling effect
in the cylinders and enables the high compression ratio (11.8:1)
employed to extract maximum energy from the fuel; a set of
low-pressure port fuel injectors that help produce a precise burn to
optimize power and efficiency under light- and medium-load
A dual air-intake system uses a primary intake passage for low and
medium engine speeds. In the higher engine speed range (above 3,600
rpm), both the primary and secondary passages are opened, helping
boost high-rpm power.
With the IS F 5.0-liter V8, Lexus made a leap in valve-control
technology with the Variable Valve Timing with intelligence by an
electric motor (VVT-iE). An electric drive motor alters the intake
camshaft phasing, which made it possible to expand VVT operational
range to lower engine speeds, where engine oil pressure is usually
not high enough to operate conventional VVT. The exhaust camshaft
uses hydraulically controlled variable valve timing.
A scavenge pump forces oil from the cylinder heads back to the oil
pan, ensuring a reliable oil supply even during cornering that
exceeds one g. The low-restriction dual-exhaust system terminates in
distinctive stacked quad diffusers.
The world's first eight-speed Sport Direct-Shift automatic
transmission combines the performance characteristics of an
automated manual-type transmission with the smoothness and
refinement of a planetary-type automatic transmission. As a result,
the driver can choose between ultra-quick manual shifts for
performance driving and smooth automatic shifts when convenience is
the top priority.
Eight speeds allow gear ratios that maximize torque up to the
tire-grip limitations in the lower ranges while optimizing
efficiency. Intuitive powertrain control optimally smoothes out
off-the-line response. The driver can select Normal, Sport or Snow
driving modes with the flip of a switch. Artificial
Intelligence-SHIFT (AI-SHIFT) complements the driver's Sport switch
selection by automatically adapting the shifting based on road
conditions and driver input. The IS F transmission is also highly
responsive to uphill/downhill driving, always selecting the best
gear for power or engine braking.
The driver can shift manually using either the console shift or
steering-wheel-mounted paddle shifters. Hydraulic-control technology
allows the IS F’s eight-speed Sport Direct Shift transmission to
perform on par with manual transmissions without sacrificing the
smoothness of a torque-converter automatic. Paddle-shifting
operation is allowed in either D or M modes, but shifts are quicker
and more direct in M mode. In M mode, the transmission will hold
each gear to the 6,800-rpm redline, and upshifts are executed in
just one-tenth of a second. At higher engine speeds, downshifts are
accompanied by automated and precise throttle blips to match engine
rpm to vehicle speed.
The Lexus IS F is based
on the robust IS platform, which was engineered from the start to
allow a high dynamic envelope. The stiff body structure and the rear
subframe are connected through several reinforcements. Much of the
IS F development took place at racetracks around the world,
including Germany's legendary Nurburgring Nordschleife, Circuit Paul
Ricard in France, Japan's Fuji Speedway and the Higashi-Fuji
Technical Center in Japan. Fuji Speedway is the IS F's home circuit,
and the shape of its turn one inspired the F logo design.
Although using the basic double-wishbone front suspension and
multi-link rear suspension configurations of the IS platform, the IS
F features a multitude of track-proven modifications. The IS F sits
an inch lower on its suspension than the standard IS models, which
lowers the center of gravity and helps provide a quicker handling
Spring and damper rates are increased, and larger-diameter
stabilizer bars are used. The rear-suspension control arms are
specific to the IS F to optimize geometry for the 19-inch wheels. In
addition, the monotube shock absorbers use a larger-diameter piston
rod. As on other IS models, the sophisticated shock-absorber design
utilizes multi-leaf linear control valves to help improve damping
force, and rebound springs offer improved body control without
degrading ride comfort.
Subframe suspension mounts are stiffer than on other IS models to
help reduce sway and ensure control under acceleration and braking.
The engine mounts are also stiffer for a more direct feel. Special
jounce stoppers on both the front and rear suspension come into play
early in the compression stroke to help reduce the sway angle when
cornering and to reduce dive when braking.
The IS F features 19-inch forged-alloy wheels by BBS® with a
distinct dark-gray finish and an asymmetrical 10-spoke design. The
front wheels are 19 x 8J, with 225/40R19 tires and 19 x 9J in the
rear, with 255/35R19 tires. Michelin Pilot Sport PS2 and Bridgestone
Potenza tires were each developed specifically for the 170-mph track
capability of the Lexus IS F. High-rigidity hub unit bearings are
engineered for rigorous, high g-force track driving. The direct-type
tire pressure monitor system allows two sets of tires to be
registered, giving the customer the benefit of a system with a set
of track tires or winter tires. The multi-information display
indicates the tire selector switch.
A specially calibrated version of Lexus' innovative Vehicle Dynamics
Integrated Management (VDIM) system helps provide superior handling
dynamics and traction control. Combining input from a variety of
sensors, VDIM is designed to anticipate the onset of a vehicle skid
or slide and help correct the situation with a combination of
braking, steering and throttle control in a way that is essentially
transparent to the driver. VDIM integration provides precise
management for EPS, Vehicle Stability Control (VSC), traction
control (TRAC), the Anti-lock Braking System (ABS), Brake Assist
(BA), Electronic Brake force Distribution (EBD), and engine torque
(via the electronically controlled throttle).
During cornering, VDIM suppresses any tendency for the inside wheel
to spin, transmitting more power to the outside wheel to help
maintain traction and momentum. When braking on a mixed-friction
surface, VDIM will direct steering assist in the direction that will
help provide greater control.
In Sport mode, VDIM allows higher dynamic thresholds before
intervening and alters steering assist to increase steering feel.
Sport mode helps provide excellent optimal vehicle control on a
track in areas where the skills of even top-level drivers are
challenged. The experienced driver can disengage VSC/TRAC by
pressing and holding the TRAC-off button for more than three
seconds. Even with VSC/TRAC disengaged, however, the system still
provides the brake-based limited-slip differential effect and ABS.
The Torsen® rear differential helps provide additional traction in
Brembo brakes were designed to the specifications of the Lexus
engineering team. The 14.2-inch ventilated, drilled front rotors are
gripped by rigid, powerful six-piston aluminum calipers, while the
13.6-inch ventilated, drilled rear rotors use two-piston calipers.
Front bumper ducts adjacent to the fog lamps stream cooling air to
the brakes. The brakes are finished with the Lexus name displayed on
technology in the IS F begins with a reinforced passenger
compartment that helps protect the occupants with front-and-rear
crush structures. Seatbelt pre-tensioners and force limiters are
used for all seating positions.
In addition to advanced dual-stage front airbags and front
seat-mounted side airbags, the Lexus Supplemental Restraint System
(SRS) includes side-curtain airbags that extend from A-pillar to
C-pillar, plus knee airbags for the driver and the front passenger.
The available Pre-Collision System (PCS) can help reduce collision
damage. The package includes Dynamic Radar Cruise Control, which
uses millimeter-wave radar to measure and maintain a pre-set
distance from a vehicle traveling ahead. PCS relies on the radar
sensor to detect obstacles in front of the car. The PCS computer,
taking sensor inputs from vehicle speed, steering angle and yaw
rate, is designed to determine whether a collision is unavoidable.
In such a situation, PCS preemptively retracts front seat belts and
pre-initializes BA so that increased braking will be applied the
instant the driver depresses the pedal.
The rear back-up camera, included with the available navigation
system, automatically projects an image of what its lens can detect
behind the car onto the navigation screen when the transmission is
The IS F interior
features specially shaped and trimmed seats that help hold the
driver comfortably and securely. The standard SmartAccess keyless
entry and push-button start allows the driver to keep the access fob
in a pocket or purse.
Standard amenities include 10-way power front seats; dual-zone
automatic climate control, a pollen filter and smog detector; power
moonroof with one-touch open/close and seven open-position settings;
power tilt-and-telescoping steering wheel; three-position memory
function for front seats, steering wheel and mirrors; all power
windows with automatic up/down operation and jam protection; an
auto-dimming rear-view mirror with HomeLink® programmable garage
door opener; automated rain-sensing wipers and heated auto-dimming
outside mirrors with integrated puddle lamps.
The air conditioning system's electrically controlled variable
compressor adjusts output to demand rather than simply cycling on
and off. The system can independently adjust upper and lower
temperatures in response to ambient conditions or sunlight.
UV-reducing, heat-absorbing glass is used throughout the car.
The standard Lexus Premium Audio System features a six-disc, in-dash
CD changer, 13 speakers, USB/iPod® connectivity, streaming audio via
Bluetooth® and an integrated XM Radio receiver (includes
complimentary 90-day trial subscription). Automatic Sound Levelizer
(ASL) maintains consistent sound levels in response to varying
extraneous noise levels. When connected to the USB port, the iPod
can be controlled through the audio system or steering wheel
controls, while information such as names for the artist, track and
album is displayed on the headunit or navigation screen.
Like all Lexus models,
the IS F offers a Mark Levinson® Premium Surround Sound Audio
System. This 14-speaker audio system features discrete 5.1
multi-channel playback with 7.1-channel speaker architecture. Its 10
amplifier channels provide 300 watts total output at less than 0.1
percent total harmonic distortion from 20 to 20,000 Hz (THD all
channels driven). The Mark Levinson system plays conventional CDs
and DVDs, plus MP3/WMA-formatted CDs. DVD movies can be viewed on
the available navigation system's color seven-inch touch screen when
the parking brake is engaged.
The available Intuitive Park Assist (IPA) system uses ultrasonic
sensors to detect objects close to the car's front and rear bumpers,
alerting the driver and showing distance to objects in the
multi-information display within the speedometer. When the IS F is
equipped with the navigation system, information on detected objects
is shown in greater detail on the seven-inch touch screen display.
The optional Lexus Navigation system features Voice Command
casual-language voice recognition and Bluetooth® phonebook download
capability. The IS F also offers a telematics system, Lexus Enform®
with Safety Connect®, available by subscription. Complimentary
one-year trial subscriptions are included on all purchases of new
Lexus vehicles equipped with these features. Safety Connect® is
standard on all vehicles while Lexus Enform with Safety Connect is
on all vehicles equipped with the optional Navigation system. The
Lexus Enform and the Safety Connect response centers operate 24
hours a day, 7 days a week—every day of the year.
Lexus Enform vehicles are factory ready for subscriptions to a
variety of innovative XM services including XM NavTraffic®, XM
NavWeather™ and XM Sports and Stocks services. XM services require
separate XM subscriptions. The XM Sports and Stocks service is
included with an XM Radio subscription. All XM services offer
complimentary 90-day trial subscriptions.
Based on the IS luxury
sport sedan, the IS F is clearly differentiated when viewed from the
front, rear and in profile. A trapezoid-shaped front bumper fascia,
a theme that is repeated at the rear, sets off the V-shape grille.
The hood’s raised center section makes room for the V8 powerplant,
and the front fenders were widened to envelop the 19-inch
low-profile tires. Total grille area is increased to ensure adequate
cooling for the 5.0-liter V8, and both upper and lower grilles
feature a special wire-mesh pattern. The lower grille is flanked by
large brake cooling ducts adjacent to standard fog lamps. The front
fenders wear a discrete silver, black and blue "F" marque.
The car’s wedge-like profile is accentuated by functional front
fender air outlets with lower edges that transition into larger
rocker panels and continue as a character line into the rear bumper.
The rear view conveys a strong parting signature for the IS F, with
a dramatic trapezoid shape and easily recognizable design elements.
Four vertically stacked exhaust diffusers, two per side, are
integrated into the rear bumper. Above them, light-emitting diode
(LED) stop and tail lamps behind clear lenses give the IS F a unique
nighttime appearance. The subtle rear spoiler is one of many
aerodynamic enhancements, which also include special underbody
panels to optimize airflow.
The interior of the IS F
features an exclusive design treatment highlighted by aluminized
composite trim, striking two-tone upholstery, aluminum-rimmed main
gauges, unique steering-wheel treatment and other special surface
treatments. The instrument panel integrates an oil-temperature
gauge, voltmeter and shift-indicator lights, and the "F" logo is
discretely showcased on the steering wheel, rear-center console and
outer seat cushions. A multi-information display located within the
speedometer integrates a trip computer that provides outside
temperature, driving range, average fuel consumption, average fuel
consumption since refueling (per tank), current fuel consumption,
average speed and the F logo. The display also includes an
oil-maintenance reminder and system warnings.
All new Lexus vehicles
