At the SEMA autoshow, GM unveiled the Jay Leno Camaro. Not only does it probably give us hints at what the Z28 will/may( since it is killed and revived so many times....) look like, it also debuts a concept Twin Turbo 3.6 SIDI V6 producing 425 HP and no sacrifice to fuel economy( so I am guessing the same 18/29 EPA as the regular V6). I hope GM decides to put that motor into production.
