Black Panhard & Levassor X77 from 1936 with six cylinders (2861 cc). Max. speed: 120 km/h
The Panhard et Levassor Dynamic is a large car introduced by the French auto-maker Panhard et Levassor as a replacement for the company’s CS model at the Paris Motor Show in October 1936.
A first prototype, known as the Dynamic 20 CV, was presented in March 1936. This was powered by a six-cylinder in-line engine of 3,485 cm3 with cylinder diameters that indeed corresponded with the French 20 hp taxation class. However, the car that entered production and was offered for sale from May 1935 as the Dynamic 130 came with the six-cylinder in-line sleeve-valve engine of 2,516 cc from the predecessor model, the Panhard et Levassor CS. This placed it in the French 14 CV taxation class. The “130” in the name was to indicate a claimed top speed of 130 km/h (81 mph).
Along with the Dynamic 130, Panhard et Levassor offered a Dynamic 140, which shared its engine with the (initially still in production) “CS Spécial” model. The engine size on this version was 2.861 cc (16 CV). Actual claimed horsepower was 75 hp (55 kW) and it was this “Dynamic 140” that was the most popular with customers, 2,230 having been produced by 1940 when war brought production to an end. By this time the car had become the last production sleeve-valve-engined car in the world.
