[1][2] It was powered by a supercharged 9-cylinder 488.2 cu in (8.0 L) Potez 9B air-cooled radial engine driving a two-bladed fixed pitch propeller.

[4] The first (racing no.10) was flown by Georges Détré, who won first place, covering the 2,000 km (1,200 mi) closed-circuit course with an average speed of 323 km/h (201 mph).

[4] Following this success, a new machine designated the Potez 533 (or 53-3) was built with various improvements for the 1934 race, including an uprated engine delivering 350 hp (260 kW) driving a Ratier variable-pitch propeller, slimmer and more streamlined fuselage and redesigned wings of increased area.

[7] Gustave Lemoine, who was flying the Potez 533 (racing no.3), completed ten 100 km (62 mi) circuits with an average speed 368 km/h (229 mph) before being forced to withdraw due to a problem with the variable-pitch propeller.
