Vauxhall's Flex appeal

The mainstream just got extreme! Vauxhall wowed the Geneva Motor Show with a four-door coupé concept which boldly demonstrated where the firm’s electric technology is heading.

The Flextreme GT/E cheekily pinches a performance name from the past to highlight the sporting prowess of the range-extender electric technology seen in the Ampera. The seductive yet wind-cheating profile has been designed to improve top speed as well as boosting economy.

Thanks to a 161bhp version of the Ampera’s electric motor and range-extending 70bhp 1.4-litre petrol engine, the Flextreme – which wore Opel badging at the show – will hit 125mph but emit 40g/km of CO2. Vauxhall says the 4.7-metre five-seater is a not-so-subtle pointer to the design and powertrain of the next Insignia due in five years. “It shows we can build big-platform cars with that technology,” said a spokesman. In the meantime, some aspects of the design will make it on to future Vauxhalls – most noticeably the axe-shaped front lights and the pronounced, low grille which is reminiscent of the Maserati GranTurismo’s.

According to chief exterior designer Malcolm Ward, the car’s long cabin and comparatively short engine compartment showcase what’s possible with this radical electric powertrain. “You get more interior space because less room is needed under the bonnet,” he said.

He added that the muscular, coupé profile proves a slippery eco shape can be achieved without resorting to the mono-curve of cars such as the Toyota Prius.
