1930 saw the fabulous C20 sleeve valve V12 finally reach production, and it was shown at that year's Paris Salon.

Can there be a more impressive car than the 28CV Voisin?

It stood at only 1.50 metres high thanks to its underslung chassis, with the longerons passing beneath the axle and springs, the 28CV was the first articulation of the sharp-edged 'angles vifs' design vocabulary that was characterise Voisins of the thirties.

Whether underslung or not, they offered more spacious interior accommodation than would at first seem from the outside.

Passengers sat in deep wells on either side of the transmission tunnel, contributing to a low centre of gravity and centralised weight distribution.

Initially available as a bare chassis (code Simoun), it was available from 1931 in three body styles: saloon (code Myra), demi-berline (code Mylord) and 4-seater cabriolet (code Myrte).

During the model year, the wheelbase was lengthened to 3.71m.

No significant changes were made for 1932 et 1933, during which, although the model was listed in the catalogue, few are thought to have been produced.
