Opel has today released a number of sketches and renderings of its upcoming Opel Antera-based Flextreme GT/E Concept car.

Powered by GM’s Voltec petrol/electric hybrid system, the Flextreme GT/E boasts a smooth, streamlined look that helps it achieve a low drag coefficient of just 0.22Cd. The tall, sloping tail and flat, enclosed underbody will help keep the car on the road, as well as improving fuel economy and performance. Opel claim the Flextreme GT/E will have a top speed in excess of 201km/h.

Another interesting bit of information is that when traveling above 48km/h, a vertical panel will extend behind each wheel arch to help improve high speed airflow and reduce turbulence. The body is constructed predominantly of carbon fibre to reduce weight.

Under full electric power, the Flextreme GT/E has a range of up to 65 kilometres, while using the petrol engine as a generator, this range is extended to over 480km.Opel claims a fuel economy figure of 1.34L/100km, a CO2 output of 40g/km and a 0-100km/g time of under nine seconds.

The Flextreme GT/E concept will debut next month at the Geneva Motor Show.
