I'm surprised I haven't seen this posted yet, as it was revealed yesterday at the Detroit motor show. In its current incarnation it's a very aggressively styled concept that's called the FT-1, and is speculated will become the next Supra. No engine specifics have been revealed, but Toyota has said it will be front engine and RWD with “a high-technology, high-performance internal combustion engine". I'm reading that as a forced induction DI engine. It Looks awfully F1-esq, with a dose of Lexus LFA thrown into the rear end. I don't love it, but I kind of dig it.
