Illustrated Guide: Turbocharger vs Supercharger

Using a turbocharger or supercharger to ‘boost’ an engine's power, thereby making a smaller engine perform like a larger one, is one of the oldest go-fast tricks in the book. It’s even more relevant nowadays, as fuel savings are realized by offsetting some of the engine’s output to a turbocharger or supercharger, rather than simply using a bigger, thirstier engine. Using boost generates the on-demand power drivers want, with reduced fuel consumption when they’re driving gently. In a nutshell, using a smaller, boosted engine instead of a larger one means drivers will burn less fuel, more of the time, with no compromise in performance.

Answering the call of shoppers after higher performance and reduced fuel consumption, more and more automakers are shifting to boosted small-displacement engines to deliver a high-performance, high-efficiency punch.
