2012 Lexus GS-F: Toyota to build a V-10-powered M5-fighter
From the October, 2007 issue of Motor Trend
/ By Todd Lassa

Take the 500-plus-horsepower, Formula 1-inspired sub-5.0-liter V-10 slated for the 2010 Lexus LF-A supercar, drop it in the body of the all-new 2011 GS sedan, and what've you got? The 2012 Lexus GS-F. Watch out, BMW M5, Audi RS6, Mercedes-Benz E63 AMG, and 2009 Cadillac CTS-v!

Details are sketchy, but engineers are said to be protecting the next-generation GS to be able to package the supercar's V-10. The GS-F apparently hasn't been approved for production. It would be a good idea, though, and not just for enthusiasts. It would cut engine costs through higher volume than by building it just for the exclusive supercar.

This also is official (kind of) notice that a V-10 has emerged as the engine Lexus will use in its supercar. Lexus hasn't announced the engine, or even made the supercar official, but Toyota was said to be considering either the V-10 or a twin-turbo version of the LS sedan's V-8. The new V-10 was to be Toyota Formula 1-based, but that series now uses a V-8, and the street engine has been developed with diminished connection to the racing engine.

The GS-F, if approved, would hit the streets about a year after an all-new GS scheduled for the 2011 model year. Expect visual mods similar to those of the forthcoming V-8-powered IS-F. Transmission is likely to be the eight-speed automatic from the LS 460, modified to allow full manual mode via paddles and ultrafast shifts.
