During this year's Frankfurt Motor Show in September, GM will be taking the wraps of its latest eco-minded concept, in the form of a new Opel-branded vehicle. The E-Flex-equipped concept will feature an electric motor that sends power to the wheels, which can be charged via either a household power outlet or the concept's ultra-efficient diesel mill.

Along with the aforementioned concept, GM will be unveiling a Opel/Vauxhall Corsa equipped with a 1.3-liter common rail diesel that produces 75 HP and releases 119 grams of carbon dioxide per kilometer traveled. The show stand will also hold the E85-capable Cadillac BLS and the HydroGen4, a Euro-spec version of the Chevy Equinox fuel cell vehicle.
