The Elise is a compact, lightweight sports car meant for track driving. As such, its competitors, such as the BMW Z4 and Porsche Boxster, generally boast more comfort but fewer at-the-limits performance attributes. The Elise comes in two trims: the entry-level Elise with a non-supercharged four-cylinder, and the Elise SC, which adds a supercharger for 29 more horsepower.
