Sorry, it's just a variable that makes these comparisons difficult. Who knows how well or at which rpm the z06 driver is shifting at. I'm sure I could look up trap speeds for both cars, if they are close, yes it is impressive, but then again is it really that impressive. I would have to imagine that for performance luxury the panamera is the bench mark, I'm sure the M5 is good, it just needs to be raced against it's peers.
