audi a1 etron Audi Shows the A1 e tron Concept at Geneva

Now that the Geneva Motor Show is in full swing, a number of interesting cars have made their debut. Amongst these is the Audi A1 e-tron concept. The e-tron functions somewhat like the Chevrolet Volt, that is, the concept makes use of a range extender engine to power the batteries. A1 e-tron uses the power dense Wankel rotary engine/generator for the purpose, for a better performance.

The lithium ion batteries on the concept weigh just 330 pounds and are arranged in a T-shape that sits mostly under the rear seat. This battery has a capacity of 12 kiloWatt-hours and can power the car for 30 miles. The range extender engine can take over from that point, and manages to take the car’s range to 130 miles.

It may look a bit short of range, but the car is ridiculously short on fuel capacity as well. The fuel tank on the e-tron holds only 3.7 gallons, and a slightly larger fuel tank would work great if the car really does have the claimed fuel effieciency of 124mpg.
