Set to debut at the Geneva Motor Show, one of Opel’s newest concept vehicles may remind you a bit of a Chevrolet Volt. Why you ask? Well, it seems they have toyed with the idea of adding the Volt’s extended-range electric vehicle drivetrain in their Flextreme GT/E concept which basically looks like a larger scaled Volt. In this case it’s a mid-sized five-door hatchback. Up until now every car shown by GM with an ER-EV drivetrain has been a fairly compact in size vehicle. Opel just seems to be, ‘stretching’ if you will, the idea. Using carbon composite and aluminum to keep weight down and close attention to aerodynamics, the Flextreme GT/E is able to achieve a low 0.22 coefficient of drag while still looking ‘cool’ sporting large 21-inch wheels. Like the Volt, the Opel Flextreme GT/E will only travel a brisk 37 miles on battery power along before it’s 1/4-liter four-cylinder gas engine/generator spins up. Obviously Opel won’t be the only car production company to follow suit on these newer ER-EV drivetrain vehicles so look for more to come, and hopefully with better battery packs/range and more options. Possibly even a cheaper price?
