Really have no idea, there's more to a car than just numbers. For all we know the Corvette has more horsepower and torque than the GT-R but the other model may corner better. Who knows.
That's true to a point but when it comes close to something that's already coming out on top even in segments well above it, anything else that comes out is benchmarked against it. Regardless, GM has to do something about the GT-R. Unlike the Viper, this could come closer to being a good handling, high-powered vehicle... like the GT-R.
