In my early college years (mid 1990's) I had a 1977 Honda Civic CVCC. That was the only car I owned that you never had to lift the throttle going around corners. Of course, you could never get a speeding ticket either......

It was actually a pretty interesting engine. Each cylinder had two interconnected combustion chambers - a small, thimble-sized CC that received a rich mixture from the smallest of the three-barreled carb, and the normal CC that received a lean mixture (somewhere on the order of 100:1, IIRC). The sparkplug sat in the rich CC, and when the rich CC lit it sent a flame into the lean mixture. It was able to meet emissions requirements without the use of a catalytic converter. Needless to see, it was slow.

I bought a 1970 MGB and never drove the Honda again.
