Remember that luscious Lexus IS-F racer study that received its fair share of unrequited attention the Tokyo Auto Salon? According to AutoBild, it turns out the car isn't an IS-F racer at all -- well, at least not beyond the hood and fact that it has four doors. The German paper reports that the car is actually a Lexus reskin of a 2004 Opel Vectra DTM racer (above, top). Even the engine is from the Opel DTM car, and not a Toyota V8. This could explain why no one at the Lexus stand at the salon would say a word about the car.
So Lexus might get away with never claiming it was a Lexus... cough, cough... but it's a bit odd that they would let Winding Road get the idea that it's the pet project of the IS-F's chief engineer, designed to show the true potential of Lexus' hot sedan and "something of what a full race IS-F might just feel like." Perhaps what a full-race IS-F might look like. Unless Lexus really intends for a full-race IS-F to feel like a 4-year-old Opel.
Thanks for the tip, Georg!
