The Lexus LF-A is not to be confused with the SUpra. That car is inspired by F-1 and will be a V-8 or V-10 depending on F-1 rules. It will be a Lexus and cost over 100k.

As for the Supra, they are currently testing cars based on a shortned Lexus GS platform, using the new 3.5 V-6, tuned for 330hp (This engine makes 280hp in the Avalon and over 300hp in the IS 350). Engineers are not 100% happy with the cars weight and handling, if they scrap this car and do a Supra only platform, it will push the car back (release date).
