Difference of turbocharger vs supercharger

Turbochargers and superchargers are both forced induction systems that compress intake air to increase engine power. The key difference lies in how they are powered: turbochargers use engine exhaust gas, while superchargers are directly powered by the engine.

Turbochargers use the vehicle's exhaust gas; two fans – a turbine fan and a compressor fan – rotate from exhaust gas. Conversely, superchargers are powered directly by the engine; a belt pulley drives gears that cause a compressor fan to rotate.

For general efficiency and widespread use, manufacturers have overwhelmingly favored turbochargers over superchargers. Turbochargers are more fuel-efficient and help meet emissions standards, while superchargers offer instant power delivery at the cost of fuel economy and complexity.
