Delahaye was initially based in Tours, Italy when it produced its first automobile in 1894, later moving to Paris in 1906. They would become one of the most successful French luxury car manufacturers of the pre-war period. The popularity of their belt-driven single and twin-cylinder horseless carriages necessitated significant investment to fuel expansion. Although he was able to find investors, he would not live long enough to see his company's success, as he passed away in 1905. Along with securing a strong financial footing, Delahaye hired some of the best engineers of the era who would carry on his legacy long after his demise. The company was issued many patents prior to World War I including the twin-cam multi-valve engine and the V6 cylinder layout.
The Delahaye Type 135 was introduced in 1935 and would enjoy a lengthy 19-year production lifespan and was built in numerous body styles by a long list of coachbuilders. Also known as the 'Coupe des Alpes' for its success in the Alpine Rally, it represented a major shift for the marque, turning away from rather pedestrian models to focus on those with sporty intentions. The engine initially displaced 3.0-liters and just prior to the outbreak of war, grew to 3.6-liters, and would continue in this guise following the war when automobile production resumed. The car's lifespan became numbered when the French government imposed heavy taxes on cars with an engine displacement over 3.0 liters.
Delahaye introduced the Type 135 in 1935 at the Paris Salon and it would be the company's mainstay for the remainder of its lifetime. It was given a new chassis designed by engineer Jean-François with welded box-section side members and pressed cross members welded to a ribbed floor. The suspension was independent with leaf springs and a live rear axle. Behind the standard 17-inch spoked wheels were cable-operated Bendix brakes.
Initially, Delahaye installed a 3.2-liter overhead valve straight-six engine with a four-bearing crankshaft from one of its trucks into the engine bay. This was the same engine powering their Type 138. With twin carburetors, the engine produced 95 horsepower; with three downdraught Solex carburetors installed, output rose to 110 hp. Transmission options included a partially synchronized four-speed manual or four-speed Cotal pre-selector unit.
A year after its introduction, Delahaye installed a larger-displacement 3,557cc engine that offered 90, 105, or 115 horsepower with either one, two, or three carburetors installed. These versions were dubbed the Type 135M. In racing guise, the 135 series took the first six places at the 1936 Marseilles race, a second at Le Mans in 1937 (the 1936 race was canceled), and first, second and fourth place at Le Mans in 1938.
Delahaye Type 135 MS (Modifiee Speciale)
At the Paris Salon in 1938, Delahaye introduced its new top-of-the-line model dubbed the Type 135 MS equipped with an updated version of the existing 3.5-liter six-cylinder engine. With larger valves and a larger cylinder head, output rose to 130 hp. With triple carburetion, output was rated at 160 bhp. Production examples rested on a 2.95m wheelbase platform while the competition models had a shortened 2.70m chassis. Production of the 135MS continued until 1954 when new owners Hotchkiss brought it to an end.
Coachwork
The modern and sophisticated Type 135 chassis provided an excellent canvas for many of the finest coachbuilders of the era to create coachwork. Among the list includes Henri Chapron, Letourner et Marchand, deVillars, Saoutchik, Guillore, Franay, Graber, and Figoni et Falaschi.
