Saturn Flextreme Concept

This is yet another GM concept built to showcase the company's E-Flex electric propulsion system. It's called the Saturn Flextreme concept and other than the badge, it's virtually the same vehicle as the Opel Flextreme that debuted in Frankfurt last fall. Given that the two companies are sharing almost every car in their lineups these days, GM figured it only made sense that they share concept vehicles as well.


In this case, the Flextreme's E-Flex drivetrain consists of an electric motor powered by lithium-ion batteries. Saturn says the system is good for 34 miles of all-electric driving. When that juice runs dry, a 1.3-liter diesel engine kicks in to recharge the batteries and extend the range.
