It may seem a little insane to compare the BMW M3 to the Toyota Prius as very few people would consider either car to be a competitor to the other. Perhaps that is exactly why Top Gear has pitted the BMW M3 against the Toyota Prius, to find out which car achieves better gas mileage on the track. Both cars are leaders in their segments, but are they truly competitors. Watch the video and find out...
