Opel, a division of General Motors (GM), has unveiled Flextreme, an eco-friendly concept car designed to emit less than 40 grams per kilometer of carbon dioxide. The electric vehicle, which debuted at the International Motor Show (IAA) in Frankfurt, Germany, is built upon E-Flex, GM's electric vehicle architecture, and uses a lithium-ion battery that can run up to 55 kilometers (km) at a time. Flextreme also incorporates versatile storage space via its rear-hinged back doors, transparent roof, tailgate doors and luggage compartment located beneath the vehicle’s floor. Prior to its European debut in Frankfurt, the Flextreme was presented at the Detroit Motor Show in January 2007, with a 1.0-liter, three-cylinder turbo gasoline engine that can run on E85, and then again at the Shanghai Motor Show in April 2007, as an electric concept car with hydrogen fuel cell propulsion. The concept car presented in Frankfurt contains two engines: a battery-operated engine and a 1.3-liter CDTI diesel engine.
