The sedan/saloon found itself overshadowed and was soon withdrawn from production after the appearance in 1946 of the Renault 4CV (which was France's top selling car in the post-Second World War years).

However, there was no estate version of the rear engined 4CV or Dauphine, and the Juvaquatre "Dauphinoise" station wagon remained in production until replaced by the Renault 4 in 1960.

[3] Four months later, in the early summer, Louis Renault gave orders for the construction of a batch of at least twenty preproduction prototypes identified as the "Juvaquatre AEB2".

[3] On the basis of the reports received following this exercise the engineers at Renault's Billancourt plant were able to apply the necessary modifications before volume production of the "AEB2" got underway in April 1938.

[3] On the publicity front, a non-stop endurance run was organised during the closing days of March 1938: a Juvaquatre was driven flat out round and round the Montlhéry racing circuit (a short distance to the west of Paris), driven by a team of four drivers who took turns to cover a distance of 5,391 kilometers (3,350 miles) during 50 hours at an average speed which was computed at slightly under 109 km/h (68 mph).

[6] Power was transmitted from the front-mounted engine to the rear wheels via a traditional three-speed manual gear box, with synchromesh on the upper two ratios.

The Renault's side-valve engine positioned it at the bargain-basement end of the class, confirmed by an advertised starting price for the two-door sedan/saloon of 16,500 Francs at the 1937 Paris Motor Show.

The Peugeot 202 was not exhibited at the 1937 show, but went on sale early in 1938 with a starting price of 21,300 Francs for a car with four doors and a more modern engine, while the Simca 8, essentially a rebadged, locally assembled Fiat, appeared at the 1937 show already with hydraulic brakes, a four-speed gear box and independent front suspension, advertised at a sticker price of 23,900 francs for the four-door "Normale" sedan/saloon.

[3] Half a class up, the front-wheel-drive 7CV Amilcar Compound, was advertised at the Motor Show at an aggressive 21,700 Francs for a "coach-normal" (2-door base version) with independent front suspension.

Ten years later, after a period of savage currency depreciation, the advertised prices had changed, but the relative positions of three competitors in the 6CV class had not.

At the 1947 Paris Motor Show the Juvaquatre, now offering four doors and independent front suspension as standard, came with an advertised starting price of 260,000 Francs.

This is the end of official production (until after the war) but a very small series was still turned out until 1942, and in 1943, 1944, and 1945, the occasional car was assembled for the occupation forces or for French government use.

There was very little to distinguish the first post-war Juvaquatres from the four-door saloon/sedan "berline" bodied version launched in 1939, but from the back there was now an opening hatch (boot/trunk lid) so that it was no longer necessary to clamber over two sets of seats in the passenger cabin in order to access the luggage compartment.

The "Break Juva 4" (station wagon) remained in production, between 1950 and 1953 retaining the dashboard and side-valve 1,003 cc engine (albeit now enhanced by an air filter) of the prewar cars.
