Vauxhall Flextreme GT/E Concept
From Vauxhall press: Vauxhall will unveil a dramatic concept car at this year’s Geneva Show that is set to boost its credentials as a leader in environmental vehicles. The Flextreme GT/E illustrates how extended-range electric vehicle (E-REV) technology can be plugged into large or mid-sized vehicles, as well as compact cars, like the upcoming Ampera.
Vauxhall calls the strategy underpinning Flextreme GT/E, ‘e-mobility unlimited’, which will effectively adapt the highly efficient E-REV drive system to vehicles across all market segments. In other words, the Flextreme GT/E concept shows that size really doesn’t matter when it comes to driving a car with zero C02 emissions.
Sleek and aerodynamic, the Flextreme GT/E achieves a projected drag co-efficient of just 0.22, allowing it to reach an estimated top speed of 125mph-plus while conserving energy and extending the driving range. Stand-out visual features include a low, wide stance, wing-shaped lights front and rear, a distinctive nose and grille, ‘floating’ C-pillars and muscular, sculptured bodywork.
The Flextreme GT/E concept also includes the groundbreaking E-REV drive system, already developed for the Vauxhall Ampera. Despite its greater size and a maximum speed of more than 125mph, the Flextreme GT/E is estimated to offer performance similar to that of the Ampera: a battery-powered driving range of up to 40 miles – with zero CO2 tailpipe emissions – and a total range of over 300 miles. Average fuel consumption is estimated at 175mpg, with CO2 emissions of less than 40g/km.
Unlike a hybrid vehicle, the wheels of the Flextreme GT/E are powered at all times by electricity. For typical journeys up to 40 miles, energy is supplied by a T-shaped lithium-ion battery pack located under the floor and rear seat.
However, unlike a battery-only electric vehicle, the Flextreme GT/E eliminates any possibility of range anxiety through fear of being stranded without power. The small petrol engine/generator is seamlessly engaged to provide electricity whenever the battery’s supply becomes depleted. In this mode, the driving range is extended to more than 300 miles, until the plug-in battery pack can be recharged or the car is refueled.
The motor in the electric drive unit delivers a substantial 370Nm of instant torque, giving lively performance and projected zero to 62mph acceleration in less than nine seconds.
The Flextreme GT/E concept is a logical next step towards Vauxhall’s emerging strategy for the electrification of the car, which will in time include products using battery, extended-range, hybrid and fuel cell technologies.
