help Tracta FAQ
What was the Tracta constant-velocity joint?
Engineer Jean-Albert Gregoire developed the Tracta joint to transmit power smoothly through the changing angles required by front-wheel drive. The design was later licensed for use in other vehicles, including military machines.
Did Tracta build front-wheel-drive racing cars?
Yes. Tracta became closely associated with lightweight front-wheel-drive sports cars rather than conventional rear-driven Grand Prix machines, demonstrating the system in demanding endurance competition.
Did Tracta compete at the 24 Hours of Le Mans?
Tracta entered cars at Le Mans repeatedly during the late 1920s and early 1930s. Its appearances helped publicize Gregoire's front-wheel-drive engineering and constant-velocity joint.
When was the French Tracta company established?
The automobile marque emerged in the 1920s through the work of Jean-Albert Gregoire and Pierre Fenaille, not in 1905. Production remained limited, and the company is remembered chiefly for its front-wheel-drive technology and Le Mans entries.
