Audi working with Mazda on Wankel for A1 e-Tron?

The Audi A1 e-Tron could be getting a Mazda Wankel Last year at the Geneva Motor Show, Audi showed us another in its seemingly endless line of fantasy e-Tron cars.

Think of the new RS 275 Trophy-R as the GT3 of Meganes, thanks to a 2.0-litre turbo tuned to 271bhp (275ps in metric, hence the name) and a crash diet stripping 100kg from its kerb weight for the sake of spicier performance and better handling.
