In the late 1960s, Citroën was hoping to build a rotary-powered small car. They got together with NSU and formed a Luxembourg-based company to develop the new Wankel powerplant, then made a few hundred Heuliez-bodied Ami coupes equipped with their proud new rotaries. These vehicles, officially designated the M35 and considered to be prototypes, were supplied to selected high-mileage Citroën buyers for long-term testing use. Sadly, the rotary Citroëns didn't work out, for the usual reasons of high fuel consumption and/or emissions, and Citroën dropped the whole idea. What if they'd stuck with the idea and Mazda hadn't? Imagine an alternate universe in which the RX-7 is French! [Citroenet]
