Auto racing (also known as automobile racing, motor racing or car racing) is a motorsport involving racing cars. It is one of the world's most watched television sports.
Car tuning is both an industry and a hobby, in which a car is modified in order to improve its performance and handling and improve the owner's driving style. As most cars leave the factory set up for average driver expectations and average conditions, tuning has become a way to personalize the characteristics of the vehicle to the owner's preference. For example cars may be altered to provide better fuel economy, produce more power at high RPM or the ride comfort may be sacrificed to provide better handling.
Auto Show / Motor Show
An Auto Show, or motorshow, is a public exhibition of current automobile models, debuts, concept cars, or out-of-production classics. It is commonly attended by automobile manufacturers. Most auto shows occur once or twice a year. They are vital to car manufacturers and local dealers as a public relations exercise, for advertising products, and for increasing publicity.
