Audi’s been playing around with its electric E-tron R8 model, chopping of the roof to make it convertible and adding a diesel engine to put it in the more usable and commercially viable hybrid category.

The new e-tron Spyder uses a lithium-ion battery hooked up to a couple 88bhp electric motors located on the front axle. With these two working alone, the Spyder can climb up to speeds of 37mph and sustain that performance for a range of 31 miles.

Then there’s the 3-litre TDI diesel engine. If you work all three engines at the same time performance goes up considerably, to a 4.4 second 0 to 60mph dash and a top speed that’s electronically limited to 155mph.

When it comes to actual fuel economy, Audi states that in hybrid mode the Spyder gets 128.4mpg and low low CO2 emissions of 59g/km. Both the performance and the green specs put it up against other high end hybrid sports cars like the Porsche 918 Spyder, and they might even make it leader of that pack.

On the entertainment side Audi’s multimedia interface can be controlled through a large touchscreen display on the dashboard, and also through less standard touch-sensitive panels located on the spokes of the steering wheel.
