Autograss racing is the biggest form of amateur motor racing in Britain with more competitors than any other. It takes place at venues throughout England, Wales, Scotland, Northern Ireland and the Republic of Ireland. It is an old motorsport and has been going since the 1960's, although only became an official motorsport in the 1970's.

autograss

Autograss is car racing on natural surfaces such as grass or mud . It is usually held on quarter-mile oval tracks although this varies. It is primarily a participatory sport, although spectators do attend races. Meetings are promoted by non-profit-making clubs, which are affiliated to the sport's governing body, the National Autograss Sports Association. The National Championships consist of one event held each year for mens classes and one for ladies and junior classes, which gathers all the local clubs together to compete. The events usually take place in August (mens) and September (ladies and juniors).

Racing requires an autograss car and a members licence from a club, which then entitles the driver to race at most events, apart from the Nationals. To race in the Nationals requires either pre-qualification or pre-registration. However there are now also some exclusive events in the British Autograss Series calendar that don't fit into the usually informal tone of most autograss events.

Autograss racing is often a family sport. Junior drivers may start racing at 12 years old, moving into the adult classes at 16. Ladies’ races are held at every meeting and the sharing of cars between family members is encouraged. There are no medical restrictions and a driver does not have to hold any qualification, even a road driving licence, to be able to take part. A racing licence, usually around £50 per year for men, £40per year for women, £30 per year for juniors, £20 per year for mechanics and £10 per year for members. All cars must have a roll cage installed and fire extinguisher fitted within easy reach of the driver. There are eleven classes of car ranging from production saloons, through progressively more modified vehicles to the single-seat 'specials'. Juniors can only race Class 1 cars or Junior Specials. There is a very basic test of driving competence by the local track marshall, consisting of a short drive ending in locking all four wheels under braking on grass.

Classes[edit]

Class 1 Standard 1000cc Minis. As with all Autograss cars they have the trim, dashboard and seats removed. The engine is standard with limited modification allowed (rebored +60 etc.). The only engine capacity allowed is 998cc bar Minis which may be modified too 1058cc to compensate . Juniors, ages 12–16, are allowed to drive class 1 cars in separate races. This class was previously restricted to Minis, but the Peugeot 106, Nissan Micra, Toyota yaris and Citroën AX have been added to the list of eligible cars from 2006. Other experimental cars are being added to the list as the classic Mini is becoming more expensive and harder to source and is no longer as competitive against the more modern cars being allowed me in. The intention of class 1 racing is to maintain an entry level class that can be constructed at a low cost, with an initial outlay of under £500 and minimal running costs at club level, although race winning cars and versions that are competitive at national level tend to cost about ten times that figure and more.

Class 2 is open to front or rear wheel drive cars up to 1300cc. The engine can be either front or rear. Cars seen most regularly in this class are Vauxhall Novas, Nissan Micras and Ford Fiestas. Since the introduction of front wheel drive cars into this class, the Vauxhall Nova has become a popular car amongst class 2 drivers. Only 2 valve/cylinder cars are allowed and there is a minimum length requirement, preventing use of 1275cc Minis and Metros. The inlet manifold is fitted with a restrictor, to even out performance amongst the vast collection of vehicles used.

Class 3 is the first of the unlimited capacity classes. The cars must have engines at the front and be rear wheel drive. This class allows front wheel drive cars to be converted to rear wheel drive and 16v engines with a maximum of 2065cc, with 8v engines being unlimited cc. This leads to powerful cars which are lightweight and fast. Examples of cars in this class are Toyota Starlets, MKII Ford Escorts and Ford anglias.

Class 4 is a modified class, with engine capacities allowed up to 1130cc. Any engine modification is allowed, except turbo and super charging. Engines are extensively modified to bring them to a competitive level, as a specific of the rules is that the original engine and position are retained. Examples of cars in this class are Minis, Hillman Imps, Citroen Saxos, Nissan Micras and Peugeot 106s.

Class 5 is a very popular starting point for people wanting to drive modified saloons. Engine capacities from 1131 to 1420cc are allowed, the engine does not have to be the original or in the original position. A lot of cars run rear engines to help improve grip.

Class 6 is for cars with unlimited engine capacity and modifications in a front engine/front wheel drive combination. Costs can be in the region of £1000 to £10000.

Class 7 is restricted to rear wheel drive cars. The engines are unlimited, but must be above 1421cc, or 1000cc if a bike engine. Many class 7 cars use motorcycle engines, in which case 2 engines may be used to power the vehicle. Quite often large sums of money are spent on the engines for these cars, including Cosworth turbo motors, large block American V8s, and V6s of different types, all highly tuned.

Class 8 is the most competitive of the Special Classes and has lowest engine capacity limit, a maximum of 1420cc for car engined specials and 1350cc for bike engined specials. Engines may be tuned, but not be turbo or super charged. All cars are rear-engined; this is not part of the regulations, but is the most effective way to get the most weight over the wheels.

Class 9 is the class most likely to win an open-class race. This class combines the high power output of the modern 2.0 litre engine with the lightness to allow better handling than the heavier class 10 vehicles. The capacity limits are between 1421cc and 2070cc and any modifications are allowed, with the usual exception of turbo and supercharging. All cars are mid-engined with most utilising a transverse gearbox layout and rear wheel drive.

Class 10 is one of the most powerful classes within Autograss racing. Another of the purpose built classes, this one has a minimum capacity of 2071cc but no upper capacity limit or limit on the modifications made to the engine (except that motorcycle engines may not have forced induction). Twin bike engines are popular with the capacity limits being between 1550cc and 4000cc, as is V8 power. Large amounts of money can be spent to gain competitiveness in this class, with fully built cars costing roughly over 55 thousand pounds.

Junior Specials this is a single seaters in which all cars have an almost standard 1.2 Vauxhall Corsa engine. As with the junior class one saloons this class is for 12 to 16 year olds.

there are also classes which are the ideas of individual clubs and only tend only to be used by that club although can be used by any person At any club. For example F600's are a cheaper, less powerful variation of class 8 invented and mainly used by Leewood motor club and there are stock hatch's a cheaper variation of class 2 invented and used by pennine autograss club at Darley moor raceway. These classes are not recognised by nasa and run their own championships independent of nasa.
