Just had a thought: I know a guy with a Corvette ZR1 (I think). I'm going to ask if he'd be interested in plotting a speed vs. mpg graph for it.
Ok, I was worried that it was just me! I'd be interested to see that data. Is it possible that the static draw is so large that it bumps up the optimal fuel efficient speed that much??
