it's funny how the cr-z is only rated at some bullshit like 32 mpg, while the camaro found a way up to ~28. (just shooting from the hip and not 100% on the numbers, but i think they are close)
But it does... GM gears their cars so tall that the highway mileage on the current generation is just unreal. I drove a V6 Camaro as a rental for a week in Califonia, and it was honestly pretty impressive. Dude at work just traded his Civic for one. At least he got the manual. We'll see how he does on highway mileage.
