The 1st Electirc Sports Car
the Roadster was developed with help from Lotus Cars. The AC motor and drivetrain technology are more advanced than versions used in the GM EV1 and AC Propulsion tzero. Tesla Motors licensed AC Propulsion's Reductive Charging patent which covers integration of the charging electronics withe the inverter, thus reducing mass, complexity and cost.

Tesla Motors has designed and built its own power electronics, motots, and other drivetrain components that incorporate this licensed techonology from AC Propulsion.

Lotus supplied the basic chassis development techonology from its Lotus Elise. Tesla engineers designed a new chassis with this development technology. The Roadster shares some components with the elise, such as the windshield, air bags, tires, some dashboard parts, and suspension components. the styling was by Barney Hatt at Lotus' design studio with imput from Tesla. The car will be assembled at the Lotus Factory in Hethel, England, with drivetrain components and body componenets supplied to the factory by Tesla
