Audi predicts new A1 e-tron concept on its stand at the Geneva motor show. It has an electric drive system, with backup power produced by a small Wankel engine.

Unless I’m mistaken, this is the first automotive use of the Wankel engine, outside Japan, since the NSU Ro80 produced in Germany during the 1960s and 70s. The Wankel rotary engine, used in the Mazda RX-7 and RX-8, does not have conventional cylinders, but uses a rotary action for a compression, combustion and exhaust.

The electric drive system on the A1 e-tron gives the car a range of more than 31 miles in city traffic, with a peak output of 102 PS. Acceleration 0 to 62 mph is quoted at 10.2 seconds, with a top speed of more than 80mph.

When the battery is flat, the compact Wankel cuts in to recharge it. With the benefit of this, ODC the range of is extended by 124 miles. The expectation is that its fuel consumption will be rated at 140.7 miles per gallon, with carbon dioxide emissions of only 45 g/km.

Audi say that the electric drivetrain, with range extending engine, require “absolutely no sacrifices in terms of sportiness or comfort” and go on to assert that the car will offer high standards in terms of driver enjoyment.
