In order to compete with Mercedes’ AMG and BMW’s M divisions, Lexus has decided to develop a performance branding badge for it’s top of the line sports-oriented cars, and it’s decided to tag them with an “F” badge. Trademarks have been filed for the model name IS-F, as well as the F logo shown above.

Looks like some kind of shoe manufacturer logo to me, but anyway, while previously it was rumoured that the BMW M3-competitor Lexus IS-F (IS500) would be powered by a new 2UR-FSE 5.0 litre V8 based on the 1UR-FSE, it is also possible that there will be no new engine and the 4.6 litre V8 1UR-FSE would be used instead. The 1UR-FSE, a 4.6 litre DOHC V8 with Dual VVT-i and direct injection with a high 11.8:1 compression ratio makes 380hp at 6,400rpm and 498Nm of torque at 4,100rpm. The 1UR-FSE also comes with an 8-speed automatic transmission, that’s right – EIGHT ratios!

While Lexus is keeping mum on the issue for the moment, the new F-line of cars is expected to be announced at the Detroit Motor Show 2007. I can just see the advertisement taglines now – “You’ve been F-ed!”
