Jeremy Clarkson drives a 1963 P50 around the office in one of our favorite Top Gear clips.
The P50 has a 49cc engine with a top speed of about 35 mph and gets 100 mpg. The engine makes less horsepower than most modern-day lawnmowers….about 4.5 hp.
There you go….a 100 mpg car that was in production almost 50 years ago!
