In the motorcycle world, engines with tiny displacements that make huge horsepower are common, and normally aspirated engines under 1 liter that make over 200 horsepower are available. In order to achieve these horsepower levels, the engines are designed to rev to well over 10,000 RPMs; unfortunately, like many extremely high-revving engines, the sacrifices are torque levels that are somewhat weak, and engines that aren’t suited to everyday driving in a heavier vehicle.
That kind of power density is unheard of in the car world, but manufacturers are getting close, while still providing impressive levels of torque. Their secret? Forced induction. None of the car engines on the list are normally aspirated, and all of them use a turbocharger (and one adds a supercharger as well). Let’s take a look at some of the most powerful car engines available with displacements under 2.0 liters, and see how they stack up to Aprilia’s most powerful engine.
