Opel Flextreme

The Opel Flextreme is a concept car by General Motors that debuted in Europe at the 2007 Frankfurt Auto Show. At the North American International Auto Show, the Flextreme was rebranded under GM's Saturn line. A diesel plug-in series hybrid, the Flextreme runs on the same E-Flex platform found in the Chevrolet Volt and the Cadillac Provoq.c

An added feature to the Flextreme is the inclusion of two Segway transporters that can be stored below the cargo space, behind the car.
