Autograss Class's 1 - 4 Breakdown
Class 1 used to be limited to 998cc minis until a few years ago but it was decided that the mini shell was becoming more difficult to get cheap. This resulted in a few other chassis being allowed into the class. Currently you are allowed a Mini saloon, Citroen AX or Fiat Cinquecento with an engine from the same car up to a maximum of 1000cc. There is also a trial currently taking place with a Peugeot. The class is also very limited to the alterations that are allowed with respect to tuning / alterations of the car.
