Delahaye was a family-owned automobile manufacturing company, founded by Émile Delahaye in 1894 in Tours, France. Manufacturing was moved to Paris following incorporation in 1898 with two marriage-related brothers-in-law, George Morane and Leon Desmarais, as Emile Delahaye's equal partners. The company built a low volume line of limited production luxury cars with coachbuilt bodies; trucks; utility and commercial vehicles; buses; and fire-trucks. Delahaye made a number of technical innovations, particular in its early years. After establishing a racing department in 1932, the company came to prominence in France in the mid-to-late 1930s, first with the International record-breaking Type 138; then, the Type 135 that famously evolved into the special short-wheelbase sports-racing Type 135CS; followed by the V12 types 145 and 155 racecars. Many races were won, and records set. The company faced setbacks due to the Second World War, and was taken over by amalgamation with arch competitor Hotchkiss in 1954. Both were absorbed by the large Brandt manufacturing organization, within months, with automotive products ended. Delahaye closed forever at the end of 1954, taking Delage along with it.

Hotchkiss were luxury cars made between 1903 and 1955 by the French company Hotchkiss et Cie in Saint-Denis, Paris. The badge for the marque showed a pair of crossed cannons, evoking the company's history as an arms manufacturer.
