Honda S660
The engines in Japan’s kei cars must displace no more than 660 cubic centimeters to qualify for tax benefits. Usually, the cars look like Kleenex boxes with wheels, not rear-drive, mid-engined roadsters. Sure, the S660 only has 63 horsepower, but it’s also got a tiny turbo, a 7700-rpm redline, and a six-speed manual. You want ponies, buy a Hellcat.
