With the smaller Ampera set to go into production next year, the Flextreme GT/E adapts the current electric and hybrid technology to offer zero CO2 emissions in a larger car.
The low roof height frontal area is designed to improve aerodynamics, while the large Vauxhall badge doubles as a socket to power the battery.
Weight-saving measures are employed throughout the design, including carbon composite outer panels and polycarbonate window glazing. The subsequent 40 per cent reduction in weight reduces energy consumption and increases the driving range of the Flextreme.
Not all new innovations are purely weight saving, however. When speeds top 30mph, a vertical panel extends along the body from behind the rear wheel arch. The ‘spoilers’ increase the aerodynamics of the car by directing air around the rear of the car.
Vauxhall’s E-REV drive system, used in the hybrid Ampera, offers a maximum speed of 125mph in the Flextreme GT/E. The lithium-ion battery has a range of 40 miles of zero emissions and a total range of 300mph.
Joining electric concept cars from Peugeot, Nissan and hybrids from Lotus and Ferrari at Geneva, the Flextreme GT/E indicates Vauxhall’s ambitions in the growing segment.
Vauxhall has not made plans to put the Flextreme into production, but its ‘e-mobility unlimited’ strategy is aimed at introducing the E-REV drive system into all models in the Vauxhall range.
