W kwietniu firma została przejęta przez producenta silników Gnome & Rhône. Gabriel Voisin został zatrudniony na stanowisku dyrektora generalnego.
Całkowicie nowy model C30 został zaprezentowany w październiku na salonie w Paryżu.
In total 30 C28s and fourteen Aerosports were built between 1935 and 1937.
On the stand of the 1937 Paris show Voisin presented their new C30 to the president of the Republic of France, Albert Lebrun. Adorned with a huge domed grille, this car differs radically from the previous achievements of the brand. Its bodywork designed by Gabriel Voisin adopts a new style but there are a few principles still dear to the builder, including the absence of any trim and looking for the best balance possible. The C30 reserves a good location to its five passengers who are all seated in the middle between the axles providing central weight distribution. That effects its quite angular aesthetic look with a bonnet extended very far forward. The car is lowered through the adoption of a rigid box chassis with integrated floor. It is 'flocked' i.e. it has a velvety appearance obtained by the application of felts which make the interior quieter. The suspension retains the patented Voisin system with four leaf springs and friction shock absorbers. Under the bonnet is the greatest surprise. No more valveless engine. They were too expensive to manufacture. Instead there is six-cylinder motor derived from the American Graham and a supercharged version is also announced.
