I drove one at the GM autoshow in motion, the car has a LOT of torque, which IMO is where the fun is. It handles great. Driven side by side with the comp G, the GXP is hands down the winner in ALL categories. The Comp G feels weak by comparison.

The airbox on the V8 looks smaller than the v6 GTP and the TB looked a LOT smaller but that might be because the MAF was combined in the older cars. I forgot where the MAF was on the V8 but thought if they open that thing up its going to HAUL. However Id bet its going to also be pretty well torque managed to save the tranny which means it wont be as fast as it should be but will have great potential.

A weakness I wish Gm would fix is their penchant for putting in transmissions and drivelines that just barely handle what comes from the factory and then fudging in a saftey margin with PCM schenanegans.

both the M6 and A4 GTO LS2 is like this.
