Just reading around and came across this, it is supposed to have a twin turbo lf3 making about 380 hp. Thats good news for you v6 guys. If this is true it has to be all wheel drive, a near 400 hp front wheel drive car seems undriveable. If this is true it might be the perfect competition for the Ford Taurus SHO.
