1936 Delahaye 135 S
- Engine
- 3.6L straight-six
- Colour
- French racing blue

The Delahaye 135 S was among the most potent pre-war French racing machines, with only 20 examples constructed. Chassis 47188, the penultimate car built, was delivered to the Works team and subsequently campaigned by Albert Divo in 1936 Grand Prix events before passing through British hands to Prince Bira and eventually Rob Walker, who drove it to 8th place at the 1939 Le Mans 24 Hours and entered it post-war through the 1950s. Repurchased by Walker in 1970, it received a new body styled on an original scale model before returning to Le Mans for a 1973 anniversary race driven by Stirling Moss.
