From a performance standpoint, of course, not even close. However, I'm not sure there will be much cross-shopping between the M2 and the Corvette as they have such different purposes and typical demographics.
It is certainly exciting for America to be producing a car that can, performance-wise, compete with much more expensive European sports cars. And given that most of the aforementioned European sports cars don't offer a manual transmission, I can see how Chevrolet justified the DCT-only decision. Given I'm not in the market for this car, I'm having difficulty understanding why that decision still bothers me so much....
