Hot Rods refers to a number of British oval racing formula (not to be confused with hot rods, which are generally road-going modified vintage cars). Hot Rod racing was introduced at Hednesford Hills Raceway in the early 1960s as a British counterpart to NASCAR-style production car racing. The term 'stock car' was not adopted because it was already in use for a form of oval racing in Britain that had evolved in a very different way than American stock cars.
In south west England, hot rod racing evolved from a class known as sports and production car racing, which began at to be held at tracks in Plymouth and St Austell in the 1950s.
Most vehicles that race are based upon European or Japanese hot hatches, although compact cabriolet cars such as the Vauxhall Tigra are also widely used. As time has moved on, the sport has evolved to allow sportier cars such as the Ginetta G40 and the Lotus Exige to be raced, in order to increase the variety of cars on track. Races are conducted on tarmac ovals 1/4 mile in length. Despite deliberate contact between cars being banned, accidents can be common due to the large number of cars (30+) racing within a tight environment.
The fastest and most expensive Rod formula are the National Hot Rods (not to be confused with the American-based National Hot Rod Association) which use tube chassis, kevlar bodies and highly tuned 2 litre straight-4 engines. This formula also races in Ireland, continental Europe and South Africa. They have similarities with some of the more sophisticated mini-stock divisions in the USA. The World Championship race for the National Hot Rods is staged at the annual spedeweekend at Foxhall Stadium in Ipswich, which is traditionally held during the first weekend of July each year.
A smaller class known as 2 Litre Hot Rods are the next class down and are usually considered a stepping stone to the National class. Using smaller Hatchback style cars such as the Citroën DS3. Their annual World Championship race is held at various tracks in England and Scotland, With every third running being staged at either of the two Spedeworth-sanctioned tracks (Tullyroan Oval or Aghadowey Oval) in Northern Ireland.
