Engine aspirations. Turbo vs supercharger

Abstract

Before 1980s, most of the motor vehicles were naturally aspirated or all motor powered, shortly said, it doesn`t require a boost power-up like a turbocharger or a supercharger. Other vehicles like commercial vehicles needed a boost for better heavy duty performance, and so does the planes, for easier transportation at the highest height. Accordingly, the first production car to feature a turbocharger was produced in 1962, being the one and only Oldsmobile Cutlass Jetfire,, although it had turbo failures marked as “Turbo Lag”. After 1980s, turbochargers were finally featured on most of the motor vehicles, being more improved, based on the materials and technology like the sealing technology and better fuel efficiency, making it as the only reason why turbocharged engines last longer than naturally aspirated engines. Nowadays, 67% of motor vehicles in Europe and Asia were turbocharged, while in North America, it`s 17% , because most of the North American production cars were either all motor or supercharged, because of the low cost. Specifically, the famous Hot Rod culture, where Americans modified their V8 powered cars by installing a supercharger from military aircraft vehicles, has influenced American car manufactures to use this sort of a boost on their V8 powered production motor vehicles like Chevrolet Camaro ZL1 or Dodge Challenger SRT Hellcat.
