The Delecroix was a Belgian automobile. First built in 1897, but commercialised in 1898, it was a light car with a rear-mounted engine and a suspension-less tubular frame.
In 1899, the company started building a model with places for carrying four people. It had a single-cylinder 3.5 hp engine.
A small car with a 2-cylinder De Dion engine was also built. This had the added advantage over many of its contemporaries of having the capability to drive backwards.
