The fastest ten score points, from 10 for first down to 1 for the tenth fastest. Points are awarded again, as in the first Run-Off. The Cars Hillclimb cars come in three categories, split into smaller groups according to the rules of championship at a particular meeting, and then into classes according to engine capacity. The main categories are for production cars, sports racing cars and single-seater racing cars. The programme usually opens with production cars, which, depending on the meeting, may range from more or less standard to heavily modofied.
Saloon cars run in different classes to sports cars.
The sports racing category encompasses the Hillclimb Supersports class and the Sports Libre classes. These sports racing machines are nominally two-seater purpose built racing cars with highly modified engines, aerodynamic wings and so forth. The single-seater racing cars come in all shapes and sizes, starting with the historic 500cc cars run to the 500 Owners Association rules. The modern equivalents, the 600cc racing cars, are powered by two or four-stroke motorcycle engines, and use a high power to weight ratio to produce remarkable performance. The 1100cc class is also dominated by bike-engined cars, and there are some highly sophisticated machines competing in this class nowadays.
