A silhouette racing car is a race car which, although bearing a superficial resemblance to a production model, differs mechanically in fundamental ways. The purpose of silhouette cars is to provide a manufacturer with a tangible link to their consumer product offerings so as to derive maximum marketing benefit from their investment in the sport. They also provide spectators with familiar, identifiable car models.
The use of a special-purpose racing car chassis rather than modifying a production car offers a number of potential benefits for a competition, which vary in importance depending on the specific class. They may include:
Silhouette cars often employ radically different chassis construction techniques, such as tubular space frames or carbon-fibre tubs in place of regular monocoques, and many also have completely different drivetrain configurations than their road-going counterparts. The body shells themselves are generally made of lightweight materials such as fibreglass or carbon fibre, and often, few parts (or none at all) are shared between the race and road versions of the cars. These changes are aimed at improving the desirable characteristics of the vehicle, such as increasing the stiffness of the chassis [3] or the output of the engine. [4]
In some silhouette classes, for instance Australian TA2 racing, the underlying chassis is the same for all cars in the series, with multiple body styles resembling different road cars available to fit the chassis.
Entire championship fields can consist of silhouettes. Sometimes, only a single class in a multi-class field may permit silhouettes. Notable racing classes where silhouette cars have been used include Trans-Am, NASCAR, Stock Car Brasil, Group 5, Group B, DTM, JGTC/Super GT, monster trucks and the Australian Supercars Championship.
Due to homologation rules (e.g. Group B rally cars), some silhouette racing cars, such as the Lancia 037 and Lancia Delta S4, also end up being sold as road cars.
Touring car racing is a motorsport road racing competition that uses race prepared touring cars. It has both similarities to and significant differences from stock car racing, which is popular in the United States.
Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be either purpose-built sports prototypes which are the highest level in sports car racing or grand tourers based on road-going models and therefore, in general, not as fast as sports prototypes. Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing, touring car racing and stock car racing. Sports car races are often, though not always, endurance races that are run over particularly long distances or large amounts of time, resulting in a larger emphasis on the reliability and efficiency of the car and its drivers as opposed to outright car performance or driver skills. The FIA World Endurance Championship is an example of one of the best known sports car racing series.

A grand tourer (GT) is a type of car that is designed for high speed and long-distance driving with performance and luxury. The most common format is a front-engine, rear-wheel-drive two-door coupé with either a two-seat or a 2+2 arrangement. Grand tourers are often the coupé derivative of luxury saloons or sedans. Some models, such as the Ferrari 250 GT, Jaguar E-Type, and Aston Martin DB5, are considered classic examples of gran turismo cars.
