Gabriel Voisin contributed immensely to the French aeronautical industry during World War I. His expertise in aircraft allowed him to implement several features in his automobile brand, Voisin. 

Voisin’s designer André Telmont developed the Vosin C27 Aerosport Coupe at a time when all designers and manufacturers were creating models that were rounded in shape. Applying elements from the Art Deco^ style, Telmont created this car with a few elements from their earlier model, Voisin C25 Aerodyne.

He gave it a pentagon (five sides) shaped door glass windows, piano key-type door handle, huge boot space, aluminium ribbing across the edges of the car body, three sets of wipers on the windscreen, etc. The most attractive part of the car was her large-size sliding roof that operated on its own at the flick of the switch provided on the dashboard (this technology was too advanced for those times).

The Mullin Automotive Museum is a world-famous museum that is present in California and belongs to Peter Mullin who runs an insurance and financial services business and has the best collection of some of the rarest cars. This Voisin C27 Aerosport Coupe is one in their possession.
