The Smart Roadster is a two-door microcar first introduced in 2003 by Smart GmbH. Sales of the Roadster and Roadster Coupé were below expectations, resulting in a halt of production of both models in November 2005 after 43,091 Roadsters were made.
Both the Roadster and Roadster Coupé are available with a removable Targa roof or an electrical Softtop. The Roadster is powered by 45 or 60 kW (61 or 82 PS) versions of the turbocharged 698CC 3-cylinder Suprex engine in the rear, which is engineered by Mercedes-Benz.
The Smart Roadster Coupé has only the more powerful 82 PS (81 hp/60 kW) engine. A steering wheel with Formula 1-style gearpaddles, to control the semi-automatic sequential transmission, is optional. With weight as low as 790 kg (1742 lb), it is meant to provide the emotion of driving a sports car at an affordable cost.
