It's hard to believe that the c7 performance pack will have similar performance to a c6 z06 when it still weighs 200lbs less with a 50 hp advantage? I wonder what the suspension tweaks come down to?
Btw I avg 26 mpg from la to Laguna seca hitting 90 often and sitting in traffic 20% of the time in my z06. But then again I got 18 mpg in my m6 in similar conditions
