Video: the world’s smallest car

For a brief spell, Jeremy conceived the world's smallest car - a two-stroke, 100cc-powered P45. And it had literally no fundamental design or engineering flaws whatsoever.

But that didn't put off Austin Coulson from Texas, USA. Because he's just built another world's smallest car that's, er, smaller. 2 foot 1in tall, 2 foot 1.75 wide, and 4 foot 1.75in long to be precise. And fully road legal...

Like the P45, it's gristled with many exciting features. There's special safety glass for the windscreen, a pair - pair - of fully functioning wipers, DOT-approved signal lights, seat belt, and a horn that works. But despite its hopelessly overwrought spec sheet, the child's quad bike-powered car can reach speeds of 33mph (limited to 25mph on public highways.

This or a P45, internet?
