The 2002-2011 MINI Cooper and MINI Cooper S are compact cars designed not only for economy but to also offer a fun driving experience, so neither a pure hydraulic system nor a complete electrically assisted steering rack would be an appropriate choice for MINI engineers. Instead, the MINI Cooper uses a different system that is a hybrid of both hydraulic and electric steering systems which they call an Electro-Hydraulic Power Assisted Steering. This type of system uses an electric motor to drive the hydraulic power steering pump instead of a belt from the engine giving you the best of both worlds: it frees up some horsepower by not being driven off the engine belts but still gives you the supreme steering feel that is so important in a well-handling and fun-to-drive small car.
Not satisfied with your engine’s performance? A supercharger offers a quick fix. Designed to supply increased air pressure (or, sometimes, air density) to an engine, superchargers achieve increased power through optimum fuel use with each engine cycle. Some stock engines aren’t designed for pulse-pounding speed – actually, the majority aren’t – so you’ll have to consider alternatives if you want the best possible power output.
