Why bother with a fourth wheel if it's only going to slow you down? The Peugeot 20Cup is a pretty hard core 170hp machine that only weighs 1100 pounds. In other words, it's like a motorcycle you can sit in.
Implications - The 20Cup is only a concept, so don't expect to see them on the road anytime soon. The car is more likely to hit the race track than the streets. Peugeot has recently announced that it plans to compete in the LMES (Le Mans Endurance Series) Championship. The car has a very futuristic look and is extremely fast. The featured images show the car in different colors such as red and black, looking totally badass.
