This is the Flextreme GT/E concept car that will be Opel’s showstar at the Geneva show next month. Using the Chevrolet Volt’s extended range electric vehicle (E-REV) technology, the 4.7-metre Flextreme is the first big bodied housing for the E-REV drivetrain.
As a recap, the wheels of E-REV cars are powered by electricity at all times (unlike hybrids). For journeys up to 60 km, energy is supplied by a lithium-ion battery pack. However, unlike regular EVs, E-REV will continue running when the battery is depleted, as a small gasoline engine then acts as a generator to provide current. GM says that this arrangement “eliminates any possibility of range anxiety through fear of being stranded without power”. Charging the Flextreme via a 230V outlet takes less than three hours.
The Flextreme GT/E has a drag co-efficient of just 0.22, which helps it reach a 200 km/h-plus top speed. Weight reduction measures include the use of carbon composite panels, polycarbonate window glazing and aluminum alloy structural components. 370 Nm of torque comes in at 0 rpm to propel the Flextreme to 100 km/h below nine seconds.
