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.
