Click the Flextreme for high-res images

Back in September 2007 at the Frankfurt Motor Show, General Motors main European brand Opel unveiled the second body style and third power-train variant of their E-Flex architecture. Since the product lines of Opel and Saturn have been converging over the past few years it makes sense to display the Flextreme at U.S. auto shows with Saturn badging. Aside from the badge changes, the Flextreme is still the same vehicle that was on the Opel stand in Germany.

To refresh you memories, the Flextreme carries on the power-train concept of the original Chevy Volt as a range extended electric vehicle. Drive to the wheels is provided by a 53kW electric motor which gets electrons from a 16kWh lithium ion battery. Where the Flextreme differs from the Volt is the range extender. The Volt uses a 1.0L three cylinder, gasoline/E85 flex-fuel engine to drive the generator. The Flextreme uses a 1.3L four cylinder diesel engine.

Aside from the diesel E-Flex setup, the other important aspects of the Flextreme are the two on-board Segway scooters mounted in a compartment in the back and the vehicle and the styling. The design of the Flextreme gives a strong preview of the design language of the next generation of Opel and Saturn vehicles starting with the upcoming Opel Insignia which will replace the Vectra and Aura. Check out the coverage of the Flextreme from Frankfurt for more details on the powertrain.
