How is the handling difference between the two?

525 RWHP and 20mpg. GM engine mgmt is pretty impressive nowadays. Have

20 mpg where?  Highway.......for mixed driving that's too optimistic....

Z06: 26mpg, 3100lbs, 505bhp
> S2000: 28mpg, 2850lbs, 240 bhp


Again.....what kind of driving is this?

It's hard for me to get 15-16 mpg mixed driving.......highway I can get mid
20s, even higher at a constant 75-80mph. I can get 30+ at a sustained 50
mph....

Granted a corvette is several hundred pounds lighter than my car....but 26
mpg mixed use is hard for me to swallow.

Mixed use fuel economy = 4 cylinder is stronger
Highway use fuel economy  = 8 cylinder is stronger

I guess I'm just whining because I rarely get such nice driving, and because
I'm always punished for enjoying myself.

Why is an LS1 powered 3rd Gen RX7, lighter, more powerful and more fuel

I guess the gas is greener on the other side of the fence.........I want to
play with a high revving no torque motor ;-)
