"In the patchy history of the Wankel engine - one car has been curiously lost to memory. We reckon that the Citroen GS Birotor deserves to be remembered for more than an aberration. Launched in 1973 it featured a 107 PS (79 kW) "
Sometimes it strikes you how innovative Citroën was as a company. The M35 is one of the most striking concepts in a long list of bold vehicle designs.
But it’s that strikingly swept body in the rear three quarters that has us going all strange. The design and production of the body was outsourced to design house Heuliez from 1969 to 1971.
The car was supplied to a select and loyal band of Citroën customers for feedback – and many elements of the car made it into live production models. The Rotary engine, for example, was used in the GS BiRotor – and the seat designs made it to the tasty Citroen SM.
A proper concept, then whose audacious design was to innovate in the real world.
