Lexus IS-F

On 6 December 2006, Lexus officially confirmed the existence of the vehicle which they called IS F in the press release. At the North American International Auto Show on January 8, 2007, the new IS F sedan was debuted to the public along with the LF-A supercar concept. Images were leaked a couple of hours before the official announcement. At its press debut, Lexus revealed that a separate "skunk works" team designed the IS F in a manner distinct from typical Lexus engineering efforts. The chief designer of the IS F, Yukihiko Yaguchi, previously worked on the Toyota Supra. Much of the IS F's suspension tuning took place at Fuji Speedway in Japan.

The IS F vehicle body was lowered by 1 cm (0.5 inches) compared to the standard IS. The hood features a bulged appearance, with sharper curve than the standard IS, due to the added space needed to contain the 5.0 L V8 engine. The drag coefficient is 0.30 Cd. The exterior also features a wire-mesh grille, changed side fenders and skirts, along with side air vents.
