What is Autograss Racing? Autograss is a non-contact motorsport that takes place on an oval (approximately 400 metre) track using a natural soil surface. Due to the close nature of the racing, thrills and spills are never far away. There are several differing classes of car, from near standard minis or small hatchbacks through to spaceframed single seaters with monster V8 or twin motorbike power! Up to 8 cars start on a straight line grid and race over short 4-8 lap races.
