World's Smallest Car

Peel P50 weighing 150 pounds (59kg) with one door, one windshield wiper and one headlight. The world's smallest production car is about 4feet long.

I guess this would mean anyone who wants to get into this car has to follow an atkins diet and stay slim and trim.

Way back in the past there has been car inventions that even ran on compressed air. If you are single and have almost nil parking space then perhaps Peel P50 is for you.
