Banger racing is a tarmac, dirt, shale and chalk track type of motorsport event popular in countries such as the United Kingdom, Ireland, Belgium and the Netherlands. Vehicles are raced against one another, with the winner being the first to the checkered flag after a set number of laps. Contact to damage an opponent's car is permitted and encouraged within the formula, with cars progressively becoming more damaged throughout an event. Races are held at an oval or tri-oval circuits that are up to long; however, on certain occasions, races are held in a figure of eight configurations. Banger racing is often confused with stock car racing, although there are differences between the two, despite often racing at the same tracks. Vehicles Banger racing vehicles are normally scrap or 'written-off' cars in varying states of disrepair. In modern bangers, there are different events held for different vehicle types. The most common type are 'Unlimited' bangers, where cars racing have no set engine size limit. Despite the high running costs, this is usually one of the most competitive classes and is favoured by most drivers because of the high speeds and car strengths. Fans often regard the unlimited class as the sport's pinnacle, with many big championship races being raced to unlimited class specs. The 'Under 2000cc' class is where cars have to have an engine under two litres in size, a formula that proves to be particularly popular with Ford variant cars such as the Mondeo and the Cougar. As these types of cars are used so often, some promotions have taken to limiting the 'Under 2000cc' class even more, by running races with additional car constraints that force drivers to use alternative vehicles to the favoured Fords. 'Under 1300cc-1800cc', also known as 'Domestic bangers', are another regular class of bangers seen in the UK, with the engine displacement cap varying on the track or promotion that is holding the event. The domestic class is most common in the 'Rookie' and 'Back to Basic' formats. 'Micros' are the smallest vehicle class used in the banger racing and usually feature cars such as the Ford Ka and the Nissan Micra, that are generally considered to be too small or uncompetitive to compete in the other classes. Micros have quickly become one of the most popular forms of banger racing, due to the cheap running and repair costs of the cars compared
