The Delahaye 135 was one of the most important French performance cars from the 1930s. In racing trim the 135 won the illustrious Monte Carlo Rally in 1937 and the 24 Hours of Le Mans in 1938, taking a slew of other wins and podium places in races as far away as Australia.

As was common at the time, Delahaye made the powered rolling chassis for the 135, it was then sent out to have a body fitted. The companies who built 135 bodies are a veritable who’s who of French coachbuilding – names like Figoni & Falaschi, Marcel Pourtout, Jacques Saoutchik, Henri Chapron, Faget-Varnay, and many more.

Fast Facts – The Delahaye 135

  • The Delahaye 135 was conceived along with the Type 134 and Type 138 in the hopes of reviving the French automaker’s flagging fortunes.
  • First released in 1935, the Delahaye 135 was powered by a 3.2 liter straight-six with overhead valves and a four-bearing crankshaft. Depending on the state of tune, this engine could produce well over 100 hp for racing applications, and 95 bhp in road trim.
  • The 135 was developed with a steel chassis, independent front suspension and a live axle rear, with a front-mounted engine powering the rear wheels. The transmission was either a partially synchronized four-speed manual or a four-speed Cotal pre-selector unit.
  • The Delahaye 135 would become the canvas upon which many of the greatest coachbuilders in France would work their magic, creating some of the most beautiful cars in history.

Émile Delahaye

Delahaye was founded back in the early days of the automobile in 1894 in the city of Tours in central France. The company was named for its founder, Émile Delahaye, a French engineer who had a particular interest in automobile racing.

The formative years of the company were focussed largely on racing, Émile Delahaye entered his four-wheeled creations into early events like the 1896 Paris–Marseille–Paris race, the 1897 Paris–Dieppe race, the 1898 by the Marseilles–Nice rally, the Course de Perigeux, and the Paris–Amsterdam–Paris race.

Within a few years the company moved their manufacturing operations to Paris, and released a number of production automobiles, early examples of which featured rear-mounted engines and tiller steering.

Émile Delahaye retired in 1901, selling his shares in the company that carried his name. It was around this time that the company left the world of racing behind and chose to instead focus on the manufacturing of heavy duty commercial vehicles like trucks, along with a limited number of automobile chassis.

By the early 1930s Delahaye was in dire financial straights, they embarked on a return to their racing roots with the development of a new line of cars – let by the Delahaye 135.

The Delahaye 135

When the Delahaye 135 was released in 1935 it proved immediately successful, and it helped to launch Delahaye back to the forefront of the performance motoring world.

Both racing and road-going versions of the 135 were offered, and buyers could choose from a long list of iconic coachbuilders to create bodies for their new cars to their own specifications.

The engineering that went into the Delahaye 135 wasn’t particularly groundbreaking and yet the car managed to become more than just the sum of its parts. The company’s experience building heavy duty trucks resulted in over-engineered powertrains that were remarkably reliable, making them particularly well-suited to endurance events like the 24 Hours of Le Mans.

The first Delahaye 135 from 1935 was powered by an inline-six cylinder engine with overhead valves, a four bearing crankshaft, and either a four-speed manual transmission with partial synchronization, or a four-speed Cotal pre-selector unit.

Image DescriptionThe body was created by famed French coachbuilder Henri Chapron, it’s a great example of the kinds of beautiful bodies that French coachbuilders were turning out at the time.

The 135 used a steel chassis with independent front suspension on leaf springs and a live axle on leaf springs in the rear. Brakes were cable operated drums fitted at each wheel.

The car would be quickly nicknamed the “Coupe des Alpes” after its success in the Alpine Rally, it also enjoyed wins in the Monte Carlo Rally in 1937, the 24 Hours of Le Mans in 1938, the 1949 Australian Grand Prix, and a slew of other races.

Production ceased during WWII, it was restarted after the war and continued until 1954. Approximately 2,000 examples of the 135 (and its related models) were built and today they’re highly-prized among collectors.
