It is based on the same GM E-Flex series hybrid platform used in the Chevy Volt, but using a diesel rather than gasoline engine. It can travel 55 kilometres (34 mi) on its lithium-ion battery before a small diesel engine starts charging the battery. In January 2008, a rebadged version of the concept was introduced at the North American International Auto Show as the Saturn Flextreme. The Opel Flextreme is expected to emit 40 grams of CO2 per km or less (according to European test procedure ECE R101 for range extender vehicles). It is expected to reach approximately 153 mpg-US (1.54 L/100 km; 184 mpg-imp).
