Well, the Tesla Roadster has almost all of those aspects covered. It's fast, fancy, handles like a dream and goes like a rocket, but it's virtually silent and it'll never burn a single drop of gasoline. Tesla's first production car is also the world's first high-performance electric car. Unlike a traditional gasoline-powered car, the Tesla Roadster doesn't contain hundreds of moving parts. It's powered by just four main systems: 1  The Energy Storage System (ESS). 2  The Power Electronics Module (PEM). 3  An electric motor. 4  A sequential manual transmission.
