Two cars were assembled in London, England [4] A new feature was a wrap-around front grille of horizontal bars.
[1][6] This placed the Suprastella towards the higher end of the price bracket occupied, with their "standard" coachbuilt bodies, by luxury automakers such as Delage and Delahaye, although buyers of these cars often had bodies designed independently by specialist coachbuilders and could easily spend considerably more.
The Suprastella was powered by a traditional flathead 8-cylinder in-line engine of 5448 cc which had already appeared, towards the end of its production run, in the Nervastella.
This was a cabriolet-bodied limousine with coachwork by Franay, delivered to the government in 1943 after it was decided that Marshal Pétain needed a new state car.
Better-known images of the state Suprastella date from August 1944 when General de Gaulle, having succeeded in entering Paris ahead of the American army, toured the city while standing in the rear part of the car and accompanied by General Lattre de Tassigny.
