Rules on measuring don't matter to me, fact is right now most of my driving is city and I consistently get 10 mpg in a stock ZL1.
I read somewhere, a while ago, that 2019 should bring a 400hp 30 mile to the gallon base Corvette. If that estimate has been moved up to this stingray its gonna be hard for me to think about another Camaro as a daily driver and go with the Vette.
But who really knows what the future holds?
PS, love my ZL1, not giving it up, don't drive that many miles a week anyway.
