Turbochargers are commonly used in passenger cars to obtain greater power output from a given engine size. The compact nature of a turbocharger means it is often a more space-efficient solution for increasing power output than fitting a larger engine. As an example, the turbo Porsche 944's acceleration performance was very similar to that of the larger-engine naturally aspirated Porsche 928.
1962: General Motors manufactured the first turbocharged production cars with the Turbo Jetfireengine used in the Oldsmobile Jetfire (a modified version of the turbocharger setup was also used in the Chevrolet Corvair Monza Spyder released a month later). A Garrett AiResearch turbocharger with integral wastegate was used. Power was significantly increased over the naturally aspirated (non-turbo) engine, however reliability of these engines was poor and the production of the engine stopped in 1963
1973: The next mass-produced turbocharged car was BMW's 2002 Turbo, introduced at the 1973 Frankfurt motor show and featuring a 2.0 L (120 cu in) four-cylinder engine. Due to excessive turbo lag, safety concerns and the 1973/1974 oil crisis, the 2002 Turbo was discontinued in 1974.
1974: At the height of the oil crisis, Porsche introduced the 911 Turbo, which was the fastest mass produced car at the time. The Porsche 911 has been available with a turbocharged engine for the majority of the years since 1974.
1977: Saab released the Saab 99 model with a turbocharged engine.
1978: Turbocharging returned to American-produced engines, in the form of the Buick Regal V6.
Since 1978, many manufacturers have produced turbocharged cars.
