A truggy is a combination of a 1/8 scale racing buggy and a stadium truck. Truggies are generally four-wheel-drive with a center differential, no transmission, a monster truck or stadium truck body and perhaps monster truck tires. The idea is not a new one since stadium trucks originally sprung from buggies. A truggy, on the other hand, takes advantage of the state-of-the-art nature of purpose-built stadium trucks. The result is the semi-scale appearance and stability of a stadium truck with the agility of a buggy. Most simple truggies are made from buggies by merely changing the wheels, tires and body mounts, but there are also truggy kits and RTRs of various levels of cost and competency.
