Tracta

The business was directed and cars were designed by the engineer Jean-Albert Grégoire, who controlled the business, with financial support from his friend Pierre Fenaille.^[2]

The cars were initially built in small numbers for competition use, but they were exhibited and offered for road use at the 1927 Paris Motor Show.^[3] They used a front-wheel-drive system featuring Grégoire's patented Tracta constant-velocity joint and sliding pillar independent front suspension and a live axle with quarter-elliptic leaf springs at the rear. 1100, 1200, 1500 and 1600 cc engines made by S.C.A.P. were available with optional Cozette supercharger. The 1500 cc car was claimed to reach 80 mph.^[4]

The first cars were made in a workshop in Versailles but Grégoire soon moved to a small factory in Asnières. After about 140 cars were made there came a change of engines with larger six-cylinder 2.7-litre units from Continental and 3- and 3.3-litre ones from Hotchkiss fitted in coupé and saloon-bodied road cars.

Notable models had the following names:

• Tracta Type A
• Tracta Type A Gephi
• Tracta Type E
• Tracta Type D2 Sport
• Tracta Spéciale

Tracta appeared at 24 Hours of Le Mans for the first time in 1927. It brought two Type A Gephi. Car number 19 did not start due to an accident on the way to the circuit and number 20 finished 7th.

Three cars competed in the 1928 Le Mans 24 Hour race, two Type As, including one driven by Grégoire (in partnership with) himself, and one Type A Gephi. All three finished, albeit well down the field.

Tracta returned to Le Mans in 1929, now with four cars, three Type As using supercharged 4-cylinder four-stroke engines and a fourth one, a Spéciale, with experimental two-stroke engine designed by the engineer Cozette (who at the time was better known as a designer of superchargers).^[2] Only two of the Tractas competing in 1929 completed the race, the two-stroke experimental car retiring after 43 laps.^[2]

By 1930 only two Type As appeared a Le Mans, with an overall 8th and 9th finishing position.

The company failed to make money from car manufacture and production stopped in 1934.^[1] Grégoire kept the factory at Asnières and used it for his own design and engineering work. He would use it for the chassis and engine of his "Sports Cabriolet" in the mid 1950s, following his acrimonious break with Hotchkiss over the technically adventurous but commercially disastrous Hotchkiss Grégoire.
