Lexus IS-F Performance Sedan

Lexus Unveils Two High-Performance Vehicles at the 2007 North American International Auto Show inc. Lexus IS-F

Lexus unveiled the IS-F high-performance luxury sedan and the LF-A sports-car concept at a press conference today at the 2007 North American International Auto Show (NAIAS) in Detroit.

The all-new 2008 Lexus IS-F high-performance luxury sedan will deliver more than 400 horsepower from a 5.0-liter V8 engine when it goes into production. The LF-A supercar concept is equipped with a V10 engine that produces more than 500 horsepower. Together, the two exciting new cars make a dramatic statement of Lexus performance.

Lexus IS-F and LF-A are very different vehicles, yet they share the same DNA, design philosophy, and heritage. Prominent in both vehicles, the "F" designation was first conceived nearly 20 years ago with a project internally coded "Circle-F," with the "F" standing for "flagship." This was the original code for what became the Lexus Division. The Circle-F designation further evolved into the code name Flagship One, or F1, and the first F1 concept developed into Lexus' first vehicle, the LS. Since then, the "F" code has come to signify a special vehicle program within Lexus that falls outside the normal engineering and development process.

"Lexus has long been perceived as the maker of mainstream luxury vehicles, but the unveiling of Lexus IS-F and LF-A not only changes this perception, it also introduces a new Lexus marque," said Bob Carter, Lexus Division group vice president and general manager. "The 'F' shared by both vehicles is the signature for a new high-performance marque conceived by an engineering team that dared to turn their dream of 'a Lexus like no other' into a reality."


Lexus IS-F Performance Sedan

Much of the development of the new Lexus IS-F took place at Fuji Speedway and the Higashi-Fuji Technical Center in Japan. The IS-F is based on the proven rear-wheel-drive Lexus IS, which is equipped with a double-wishbone front and multi-link rear suspension. As well as the IS performs, Lexus engineers demanded much more of the all-new IS-F. The result is a performance tuned 5.0-liter V8 engine, topped with specially engineered heads fed by a two-stage intake system, that produces 400-plus horsepower and more than 350 ft.-lbs. of torque. The all-new IS-F is equipped with engine-oil and transmission-fluid coolers for high-speed performance and a cylinder head-scavenging oil pump for high g-force driving.

Lexus 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 with great smoothness, and the torque converter allows for great launch ability for fast standing-start acceleration that will register a zero-to-60 time in less than 4.9 seconds.

This unique transmission of Lexus IS-F also features an advanced Manual mode. A pair of paddles located within a fingertip's reach behind the steering wheel enables the driver to make ultra-fast up-shift gear changes within a tenth of a second. Downshifts are accompanied by automated and incredibly precise throttle blips to match engine RPM to vehicle speed.
