Audi A1 e-tron: Coming with Wankel rotary generator

Audi A1 e-tron
Audi and Wankel engines have quite a history so we are excited to see the Audi A1 e-tron being fitted with a Wankel rotary generator for extended range. There are no pictures published yet, expect them to be here soon.

However, unlike the Volt or Fisker Karma, the A1 is using a single-rotor Wankel engine to drive the generator. While Wankels are not renowned for their fuel efficiency (much the opposite in fact), in this application it could work well thanks to its high power density.

The range with the Wankel running is bumped up by another 124 miles to a total of 155. With only a 15kW generator available to sustain the battery, it will be interesting to see how much performance is degraded in that mode. Audi claims the A1 e-tron achieves 123.8 miles per gallon (U.S.) on the draft EU standard for ER-EVs.
