Audi Plans E-REV Using Rotary Engine

German car manufacturer Audi has recently revealed plans of developing an extended-range electric vehicle that uses a rotary engine to recharge the batteries. The company is currently testing prototypes of its A1 subcompact vehicle with an electric drivetrain and a Wankel rotary range extender.

As we previously reported, the automaker is testing prototypes based on the A1 e-tron concept. The first all-electric Audi e-tron model to enter production will be based on the e-tron sports car concept first shown at the 2009 Frankfurt Show and is expected to be available in Europe from late 2012.

Unfortunately, no decision has been made for the US market. Audi is expected to reintroduce the A2 name for the vehicle, an extremely slow selling model that was produced in Europe from late 1999 to 2005.

"The first prototype car is running very well at the moment. We hope to make a small series at the end of 2012 or the beginning of 2013," Michael Dick, head of research and development was quoted as saying by Motor Trend.

Delivering an output equivalent to 102PS, the lithium-ion battery mounted within the floor assembly in front of the rear axle of the A1 e-tron powers it to a top speed of 81 mph (130 km/h) and gives it a range of more than 31 miles (50 km) in city traffic.

"It is a big favorite for me personally, this concept, because it works perfectly with this city car,"
Dick told the aforementioned source. "We have the full space, it remains a four-seater, and it has full space in the trunk. It's designed to drive pure electric, but this takes the fear away from people of losing power when they are driving. The range extender is like the auxiliary engine in a sailboat. If there is no wind, then you motor in to your harbor."
