Why is touring car racing called touring car racing?

Touring car racing is called so because it features modified production cars that are based on standard road-going vehicles, often referred to as "touring cars." The term originated in the early 20th century when automobiles were used for long-distance travel, or "touring." These races emphasize the performance and handling of cars that are more accessible to everyday drivers, distinguishing them from purpose-built race cars. The format often includes a mix of manufacturers and models, adding to the competitive and diverse nature of the sport.
