La Citroën M35 est un prototype développé par le constructeur français en 1969, sur une base d’Ami 8 par le carrossier Heuliez soustraite de ses deux portes arrière et équipée d’un châssis à suspension oléopneumatique et d’un moteur rotatif bi-rotor. Elles adoptent une couleur gris métal ainsi que la mention « Prototype Citroën M35 » suivi de leur numéro respectif sur les ailes avant.
Moins de 500 exemplaires furent fabriqués et moins de quarante sont à ce jour recensés.
Ala fin des années 60, Citroën en quête d’innovations s’intéresse au moteur rotatif Wankel. Une collaboration commence donc avec la société NSU, dont un premier contrat dit « Comoto » permet l’exploitation des moteurs Wankel. En 1969, NSU, en faillite, est rachetée par Volkswagen et le constructeur français est donc contraint de continuer seul dans l’aventure Wankel.
Le directeur des relations publiques Jacques Wolgensinger a l’idée de produire une petite série de véhicules expérimentaux et de les confier à des clients. L’objectif était d’avoir un panel de personnes évoluant dans des régions ayant des climats et des reliefs différents. Les consommateurs se transforment donc en testeurs officiels Citroën et seront chargés de transmettre leurs expériences au Bureau d’Etude pour tester et améliorer cette technologie. Vendue contre la somme de 14 120 Francs, les clients bénéficiaient de deux ans de garantie totale sur le moteur. L’expérience est un échec et Citroën s‘efforcera de racheter la majeure partie de ces autos une fois l’expérience terminée.
L’exemplaire que nous vous présentons aujourd’hui a une histoire limpide. Le docteur Marion, fidèle client de la marque aux Chevrons avait été sélectionné pour tester le prototype. Après plus de 40 000 km parcourus, il se rapproche de son concessionnaire Citroën car le moteur chauffe. Deux choix s’offrent donc à Monsieur Blanc, passez un coup de fil à la maison mère pour transformer la M35 en César ou la racheter et la garder pour réparer le moteur. Il choisit heureusement la 2éme option. Mais la réparation d’un moteur rotatif n’est pas une mince affaire, et il abandonne. Ce n’est que de nombreuses années plus tard, que son petit-fils entreprend la remise en route de l’auto (aidé d’un spécialiste NSU), avec succès, pour permettre à son grand père de faire quelques tours de roue. La voiture a toujours son immatriculation d’origine. Elle est dans un état exceptionnel et est prête à prendre la route. Elle a entre autres : échappement inox neuf, stator trochoïde neuf, segmentation neuve, pompe à eau refaite à neuf, sphères suspension et pompe hydraulique neuves.
Cette voiture est un marqueur d’une époque d’innovations techniques automobiles prolifiques, pendant laquelle un constructeur confiait des prototypes à ses clients, pas certains que cela soit possible aujourd’hui !
A noter, un ensemble de documentations sera fourni avec la voiture, comprenant un book de pièces détachées.

The Citroën M35 is a prototype developed by the French manufacturer in 1969, on an Ami 8 base by the coachbuilder Heuliez, with the two rear doors removed and equipped with an oleo-pneumatic suspension chassis and a bi-rotor engine. They were painted in a metallic grey colour with the words "Prototype Citroën M35" followed by their respective numbers on the front wings.
Less than 500 were made and fewer than forty are known to date.
At the end of the 1960s, Citroën, in search of innovations, became interested in the Wankel rotary engine. A collaboration began with NSU, whose first contract, known as the "Comoto" contract, allowed the use of Wankel engines. In 1969, NSU, which had gone bankrupt, was taken over by Volkswagen and the French manufacturer was therefore forced to continue the Wankel adventure alone.
The public relations director Jacques Wolgensinger had the idea of producing a small series of experimental vehicles and entrusting them to customers. The aim was to have a panel of people in regions with different climates and terrain. The consumers thus became official Citroën testers and were responsible for passing on their experiences to the Design Office in order to test and improve this technology. Sold for 14,120 francs, customers were given a two-year full engine warranty. The experiment was a failure and Citroën tried to buy back most of these cars once the experiment was over.
The car we are presenting today has a clear story. Dr Marion, a loyal customer of the Chevron brand, was selected to test the prototype. After more than 40,000 km, he approached his Citroën dealer because the engine was getting hot. Mr Blanc had two choices: he could call the parent company to transform the M35 into a Caesar or he could buy it and keep it to repair the engine. Fortunately, he chose the second option. But repairing a rotary engine is no easy task, and he gave up. It was not until many years later that his grandson undertook to restart the car (with the help of an NSU specialist), with success, to allow his grandfather to drive it a few times. The car still has its original registration. It is in exceptional condition and is ready for the road. Amongst other things, it has new stainless steel exhaust, new trochoidal stator, new segmentation, new water pump, new suspension spheres and new hydraulic pump.
This car is a marker of an era of prolific automotive technical innovation, during which a manufacturer entrusted its customers with prototypes, not sure if this is possible today!
A set of documentation will be supplied with the car, including a parts book.
