The must fun I've ever had while driving was with the family '99 Honda Civic. Zero power. Zero torque. But, man, it was like driving a go kart in the streets. I'd zip through mountain passes with the engine revving to hell but in reality I'd only be barely going the speed limit.

I did the same mountain pass in my Subaru recently and didn't even notice I was going 20mph over the speed limit. The engine was silent and still responsive.
