The Opel/Vauxhall Flextreme GT/E Concept is a vehicle which builds on the foundations of the Opel Flextreme concept from 2007. This concept is designed to illustrate the usefulness of extended-range EV systems in large or midsize cars. The Flextreme GT/E features aerodynamic shape and a low drag coefficient to maximize speed and performance.
The Flextreme GT/E’s aerodynamic shape, and drag coefficient of just 0.22, means the car can extract the highest speed and performance possible from its electric motors. The vehicle is driven entirely by electric motors, which rely on a lithium-ion battery. The motors can propel the vehicle to a top speed of 125mph and a 0-60mph time of under nine seconds. The vehicle’s onboard batteries are good for a range of 40 miles, after which a small 1.4-liter 4-cyclinder engine kicks in to act as a generator.
With the generator the vehicle’s range is extended to 300 miles with a fuel efficiency of 175mpg. The exterior design of the Flextreme GT/E has been dedicated for maximum aerodynamic efficiency. At speeds above 30mph, a vertical panel extends along the body from the air extraction slot behind each rear wheel-arch, to guide high-speed airflow around the rear corners of the car to further reduce turbulence.
