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".

Vehicle Outline
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 car stimulation.

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.
