The all-new 2008 IS-F will target the BMW M3 and Audi RS4, delivering more than 400 horsepower and 350 ft.-lbs. of torque from a 5.0-liter V8 engine.
It will eventually be offered as a two-door coupe, as well.
Much of the development of the new IS-F took place at Fuji Speedway and the Higashi-Fuji Technical Center in Japan.
The IS-F is based on the rear-wheel-drive Lexus IS, which is equipped with a double-wishbone front and multi-link rear suspension.
The IS-F engine is mated to the world’s first eight-speed "direct sport-shift" transmission.
A new torque-converter lock-up control was developed that allows for a direct, crisp gear change through the constant lock-up of the torque converter in second through eighth gears.
In Drive mode, the IS-F transmission performs smoothly, and the torque converter allows for quick 0-60 acceleration in less than 4.9 seconds.
The transmission also features a manual mode operated via a pair of paddles.
Downshifts are accompanied by automated throttle blips to match engine RPM to vehicle speed.
Heavy-duty Brembo brakes with 14.2-inch discs and six-piston calipers ensure all the power is kept under control.
The IS-F features custom-designed 19-inch forged alloy wheels as standard.
