I was impressed at the current GM V6 motor. I noticed it in the Camaro, 304hp and 273 lb/ft torque from a 3.6! DOHC, VVT, Direct injection and all of this on 87 octane. That is right up there with the best Honda/Acura V6, the Infinity 3.5, 3.7motors you name it. The Camaro did however impress with the ultra cheap interior and lack of strut bars just to name a few.
The LFA was the king of the show imo, especially with that exposed wheelbase. Nissan, Ferrari, Lamborghini epic fail.
