A supersprint is a speed event where cars are sent out onto the circuit in pairs to set their fastest single lap. The pairings are sent out at 10 second intervals, with the fastest pair at the front to minimise overtaking. It is not a race – in fact, anyone found to be racing is sent straight to the stewards.
Cars are divided into seven types.
– Type 1 is for standard registered road cars.
– Type 2 is for modified registered road cars.
– Type 3 is for touring cars and production sports cars which can be modified as per the Improved Production regulations.
– Type 4 is for sports sedans.
– Type 5 is for open-wheelers, sports/racing cars and clubman sports cars.
– Type 6 is for time attack cars.
– Type SV (Special Vehicles) is for road registered kit cars, modified road registered cars and other cars running on slicks.
All types have classes within them loosely based on engine size.
The whole field (usually about 100 cars) is split into colour groups based on potential performance. This ensures that fast cars share the track with other fast cars, and slower with the same.
A run is eight minutes on the track, and each competitor will get about five or six runs. At the end of the day, each competitor’s fastest individual lap is compared with every other driver to get an outright result and with every other driver in the class to get a class result.
