The Primaquatre was first exhibited on 29 December 1930 as the Type KZ6, being a development from to the KZ series.

Its 4-cylinder engine was of 2120 cc providing a published maximum output of 35 horsepower (26 kW) at 2900 rpm.

In January 1936 the New Primaquatre (Type ACL1) appeared, featuring with a new 2383 cc (14CV) engine providing up to 48 PS (35 kW; 47 hp) at 3200 rpm.

In following years the types ACL2, BDF1, BDF2 and BDS1 were introduced, and were produced until the early summer of 1940 when the unexpected speed of the German invasion put an end to most passenger car production in France.

Two changes towards the end of 1937 were the introduction of Renault's newly developed mechanical brake servo, as well as the removal of one of the two access points for the fuel tank which from now on had to be filled using a single fuel filler on the right hand side of the rear panel.
