The Tesla Roadster was based on the aluminum tub from the contemporary Lotus Elise, with which it shared its windshield and windshield frame. The remainder of the carbon-fiber body panels were unique to the Tesla, which featured a 2? longer wheelbase than the Elise. This example is finished in Twilight Blue Metallic and is equipped with a removable body-color roof panel, a black removable soft top, an exterior charging port, and LED taillights.
