Go-kart

A go-kart (often just kart) is a small four-wheeled vehicle. Go-karts come in all shapes and forms, from motorless models to high-powered racing machines, some, like Superkarts, being able to beat racing cars on long circuits.

Gravity racers, usually referred to as Soap Box Derby carts, are the simplest type of go-karts. They are propelled by gravity, with some races taking place down a single hill.
