Turbo refers to a type of forced induction system used in internal combustion engines. It works by using a turbine driven by exhaust gases to compress incoming air, allowing more air and fuel to enter the engine. This process increases the engine's power output without significantly increasing its size. The term "turbo" is often associated with performance vehicles, as it enhances acceleration and efficiency. Many modern cars, including those from manufacturers like Volkswagen and Ford, utilize turbochargers to improve fuel economy while delivering a sportier driving experience. Turbo technology has become popular in both racing and everyday vehicles.
