The story
History
Établissements N. Delsaux was based at Guesnain, near Douai, in the Nord, one of the many makers of licence-free cars in the north of France in the late 1970s.source 1source 2 Its Modulo appeared in 1979 by the old microcarfan.com’s account; the German Wikipedia starts production in 1980, and perhaps one dates a show debut and the other the start of production.source 2source 1 It began with three wheels and, following the fashion, soon had four.source 2
The old site found its originality in the shape rather than the mechanicals. Once again, it noted, the small 47 cc Sachs had the heavy task of moving the car along.source 2 The German Wikipedia gives the engine as an air-cooled two-stroke at the back, and the car as a two-seater with a plastic body. It measured 1,840 by 1,250 mm (6 ft 0 in by 4 ft 1 in), stood 1,390 mm (4 ft 7 in) tall and weighed 149 kg (328 lb).source 1
In 1982 a new body arrived, the Minimax, which the German Wikipedia calls the Modulo Minimax; everything else stayed the same.source 2source 1 The firm closed in 1983, having sold its few cars in tiny numbers; after that, the old site says, all trace of it is lost.source 2source 1
What we do not know
The founder’s first name, the prices, how many were built, the sizes of the three-wheeler and the Minimax, and whether any survives are all missing. No French period source has been found.
