The Voisin V12 was an automobile unveiled at the 1936 Paris Motor Show.

The economic situation of Voisin was in such a way that sales had collapsed. Gabriel Voisin intendded to strike the spirits of the public at the 1936 Paris Motor Show.

Voisin imagined that only a glorious feat could possibly boost the business.

The V12 was fitted with an engine which was made by coupling two six cylinders engines of the companies own design.

Two versions of this 12-straight were planned. A "normal" one with a 3150 mm wheelbase and a "long" one with a 3500 mm wheelbase.

The car never reached production and only a few prototypes were produced.
