After an attempt to enter the luxury market with the AK, which did not get beyond the prototype stage, the company decided on a one model policy and introduced the Coventry designed AM in 1923. Later that year the Coventry plant was sold to Morris. Henry Mann Ainsworth (1884–1971) and Alfred Herbert Wilde (1889 – 1930) who had run it, moved to Paris to become general manager and chief engineer of the car division respectively.

In 1926 construction of the new factory in the Boulevard Ornano was completed and in 1929 Hotchkiss got hold of a steel press allowing in-house manufacture of steel bodies. The one model policy lasted until 1929 when the six-cylinder AM73 and AM80 models were announced. “73” and “80” stood for the bore of the engines used, a naming theme picked up again later in 1936 after a brief hiatus.

Although most cars had bodies that were factory built, Hotchkiss still was a luxury car brand, and so coachbuilder Veth and Sons built a small number of bodies for the AM80.

The AM models were replaced by a new range in 1933 with a new naming system.

The 411 was an 11CV model with four-cylinder engine, the 413 a 13CV four and the 615, 617 and 620 were similar six-cylinder types. The 1936 686, which replaced the 620, was available as the high-performance Grand Sport and 1937 Paris-Nice with twin carburettors and these allowed Hotchkiss to win the Monte Carlo Rally in 1932, 1933, 1934, 1939, 1949 and 1950. The new naming scheme introduced in 1936 consisted of the number of cylinders, followed by the bore of the engine (in millimetres).
