TCR meaning in Sports ?

Touring car racing is a motorsport road racing competition with heavily modified road-going cars. It has both similarities to and significant differences from stock car racing, which is popular in the United States.

While the cars do not move as fast as those in formula or sports car races, their similarity both to one another and to fans' own vehicles makes for entertaining, well-supported racing. The lesser use of aerodynamics means following cars have a much easier time passing than in open-wheel racing, and the more substantial bodies of the cars makes the subtle bumping and nudging for overtaking much more acceptable as part of racing.

As well as short "sprint" races, many touring car series include one or more endurance races, which last anything from 3 to 24 hours and are a test of reliability and pit crews as much as car, driver speed, and consistency.
