The Speed indoor go-kart track opened in June 1996. In 1997, it became the world’s first natural gas go-kart track in operation. It is run by Gasversorgung Süddeutschland (GVS), a gas supplier in southern Germany, and Erdgas Südwest, a natural gas supplier in the area. Using natural gas helps significantly reduce harmful emissions, thus contributing to cleaner air and a much more comfortable environment in the track halls.
