First seen at the 2008 Detroit Auto Show, the Saturn Flextreme Concept was a virtual clone of the Opel Flextreme Concept which had been unveiled at the 2007 Frankfort Auto Show only a few weeks earlier. The Flextreme concept was a 4-door compact car featuring a plug-in serial-hybrid drivetrain similar to that introduced in the Chevrolet Volt Concept introduced at the Detroit Show a year earlier.

Unlike the Volt Concept, which featured a small gasoline engine, the Flextreme was powered by a tiny 1.3-liter diesel. When fully charged, the Flextreme was claimed to travel up to 34 miles on electric power alone, after which the diesel engine took over. Saturn claimed a combined electric/diesel range of 444 miles.

For urban explorers, a pair of Segway Personal Transporters were stored under the vehicle’s cargo area and could be accessed from outside of the car. No word on if the Segway batteries were charged while in storage under the car.

For this reason, Volt variants like the Opel and Saturn Flextreme never matured into full production models.
