Even if the mid-engine 'vette base engine is a crappy little 450 hp non-breathing cam in block unit like they use in the current Corvette, the mid engine 'vette could be really great on the road course. Just the balance from having the mid-engine and the visibility with the small, low hood could make a huge difference in handling enjoyment. It should be interesting to see how light the mid engine 'vette ends up being.Which will be slower than the GT500. The cool TT one will be well over $100k.
And get real - any mid-engine V8 sports car is cool. If GM can make a mid-engine 'vette that I can afford it will be super difficult to resist buying one. Unless they do something dumb like no manual transmission option.
The GT500 may end up being more of a point and shoot, or run a few laps and then wait for the tires to cool kind of car.
