TOKYO, May 17, 2007 — Lexus announced today that it will begin sales in Japan, starting on December 25, of the “IS F”*. The IS F is a Lexus “F” premium sports car based on the concept of
proposing a new level of performance for Lexus through a refinement of
basic performance with the addition of new cruising technology. The
vehicle was developed to pursue, to the fullest extent possible, the
“joy of driving” — which is one of the fundamental appeals of the
automobile — by responding reliably and performing as intended.
Based on the IS series, the IS F boasts a completely new engine and
transmission, an exclusive suspension and specially selected aluminum
wheels and tires. The vehicle was tested extensively on race circuits
in Japan and overseas, including Fuji Speedway, in order to demonstrate
its full potential. Detailed attention to the responsiveness of the
acceleration, gear shifting, steering and brakes, as well as to the
actual experience of quality (such as engine sound and the sensation of
acceleration), has created a new type of driving pleasure — not just
for the driver but for passengers as well — thus expressing the
emotional appeal of the Lexus brand.
Based on the idea of creating a vehicle that can run on various types
of roads, the vehicle was extensively tested on race circuits,
including Higashifuji Technical Center and Fuji Speedway. The "F" in
the IS F name comes from the "F" in "Fuji Speedway".
Note: Products described in this and in any attached materials are for the Japanese market only.

1. Performance that Can Maximize Driving Pleasure
- The newly developed 5.0-liter V8 engine is a D-4S (direct injection
four-stroke gasoline engine, superior version) that combines both port
and direct fuel injection. Advanced technologies, including electric
motor-driven VVT-iE (Variable Valve Timing-intelligent system by
Electric motor) on the intake side of the Dual VVT-i (Dual Variable
Valve Timing-intelligent system), maximize the performance of the
engine. This naturally aspirated engine provides a feeling of linear
acceleration, high acceleration response and powerful, enjoyable
acceleration even at high engine speeds.
- By adopting the dual-intake system, the IS F provides smooth and
even torque at low or medium engine speeds and high torque with both
air inlets open at high engine speeds. In addition, the engine sound
goes through three transitions in line with rpm to offer true sports

- The 8-Speed Sport Direct Shift transmission is based on the
eight-speed automatic transmission used on the LS460 series, with
electronic control technology that provides the benefits of both the
smooth shifting of an automatic transmission for comfortable driving
and a full-scale, sporty manual transmission that does not need a
clutch — which is without precedent anywhere in the world* for an
eight-speed transmission. The two-pedal sports transmission also
offers new value and perfectly suits a premium sports car. In addition
to smooth shifting when the lever is in "D", the torque converter
allows smooth and powerful acceleration when starting up in first-gear
by putting the lever in "M". In gears two through eight, the direct
connection between the engine and the transmission results in direct
acceleration response. While achieving one of the fastest gear-change
responses in the world, the transmission also has a blipping (revving)
control feature that–in the fashion of the heel and toe technique used
by race drivers–automatically increases engine rotation speed during
downshifts to avoid downshift jolts. In addition, the IS F also
features a special paddle shifter that can be operated without the need
to remove one’s hand from the steering wheel.
- The springs, shock absorbers, stabilizers and other parts have been
optimally tuned for an exclusive suspension that is based on the IS
series suspension, which provides both outstanding stability and a
feeling of agility. The vehicle offers excellent cruising performance
that is capable of handling race circuits.
- In addition to 19-inch forged aluminum wheels that are both strong
and light, the IS F uses large-diameter, wide 225/40R19 tires at the
front and 255/35R19 tires at the rear for superior gripping
performance, excellent handling and cruising stability.
- The IS F has high-performance brakes that can withstand even extreme braking on race circuits.
- The VDIM (Vehicle Dynamics Integrated Management) system stabilizes
the vehicle by coordinating control and achieving an optimum balance
between drive power, steering and braking, thus allowing high
preventive safety. The IS F’s VDIM has a "sports" mode that ensures
safety while maximizing vehicle performance.

2. Interior and Exterior Designs and Exclusive Equipment Appeal to a Sports Car Mindset
- The hood, grille, front fenders and front and rear bumpers, rocker
panel molding, rear spoiler and other elements were designed
exclusively for the IS F based on the Lexus design philosophy
"L-finesse"*. The exterior styling has a dynamic yet simple form that
expresses the vehicle’s cruising performance and functionality.
- The sharply contrasted interior uses the colors black and white
with blue accents that are exquisitely placed. The center console and
armrests feature special ornamentation.
- The gauges have an exclusive metal ring achieved through cutting
work. The gauge needles feature blue LEDs and a speedometer that goes
up to 300km/h. (Vehicles with domestic specifications have a function
to limit speeds that activates at 180km/h.)
- The four sports-car-style seats emphasize a degree of holding power that can withstand cruising on race circuits.
- The 14-speaker Mark Levinson® premium surround-sound audio system
has been tuned specifically for the IS F (optional on all vehicles in
*Created by combining "leading-edge" and "finesse" design concepts
3. Class-leading Safety and Environmental Performance*
- The Pre-crash Safety System, which uses millimeter-wave radar,
warns drivers that a front-end collision is imminent and works to
reduce injury if an accident occurs (optional on all vehicles in the
- Along with an impact-absorbing body and strong cabin, the IS F
achieves further contributions to class-leading safety performance
through dual-stage SRS (Supplemental Restraint System) airbags for the
driver and front passenger seat (SRS twin-chamber airbag for the front
passenger seat); SRS knee airbags for the driver and front passenger
seat; SRS side airbags for the driver and front passenger seat; and SRS
curtain shield airbags for both front and rear seats.
- Efforts were made to improve fuel efficiency in order to reduce CO2
emissions. The vehicle boasts a fuel efficiency of 8.2km/l in the
10-15 test cycle outlined by the Japanese Ministry of Land,
Infrastructure and Transport (MLIT) with CO2
emissions under the test cycle just 283g/km. Both NOx (nitrogen
oxides) and NMHC (non-methane hydrocarbons) have also been reduced,
achieving emissions levels 75% lower than the 2005 standards under the
MLIT’s Approval System for Low-emission Vehicles.
- The IS F benefits from Eco-VAS (Eco-Vehicle Assessment System) —
Toyota’s original comprehensive environmental impact assessment system
— achieving overall reduction of environmental impact throughout the
vehicle’s entire lifecycle. Environmental targets were set in the
initial vehicle development stage and a life cycle assessment was
carried out to achieve a reduction of air contaminants and CO2, etc., throughout all stages of the vehicle’s life from production and use to disposal.
- In addition to using highly recyclable materials, greater attention
has been paid to the environment by, among other means, reducing the
use of substances of concern such as lead, mercury, cadmium and
hexavalent chromium, achieving the Japanese automobile industry’s
voluntary goals of eliminating the use of these substances.
