Doriot, Flandrin & Parant (commonly abbreviated as D.F.P.) was a French car manufacturer situated in Courbevoie, Seine, with operations spanning from 1906 until 1926.
The company was established in 1906 by Auguste Doriot and Ludovic Flandrin, who previously worked for Peugeot and Clément-Bayard. Their first offering was a lightweight automobile powered by a single-cylinder engine, sold under the Doriot-Flandrin name.
In 1908, Alexandre and Jules-René Parant became partners, prompting the expansion of the company’s title. Production evolved to include four-cylinder vehicles equipped with Chapuis-Dornier engines, while continuing to manufacture single-cylinder models until their phase-out in 1910. Subsequently, a smaller four-cylinder engine of 1592 cc was introduced.
By 1912, D.F.P. had begun producing engines internally. The 2-litre 12/15 model earned acclaim when W. O. Bentley competed with a modified version featuring aluminium alloy pistons at Brooklands. These pistons were also incorporated into certain 12/40 hp models produced from 1914, which were notable for their electric starters.
Following World War I, the company utilized proprietary engines primarily sourced from Altos and Sargant. In 1923, D.F.P. resumed manufacturing its own engines with the launch of the 1924 cc 13/50 model and introduced the D.F. Petite, a compact car powered by a 1098 cc C.I.M.E. engine.
Production ended in 1926 when the premises were sold to the light car manufacturer Lafitte, which itself ceased operations in 1928.
