still on display at the Brussels Motor Show in January 1948, adding to the variety on the Renault show stand and suggesting that at that stage it was still intended to produce more Juvaquatre coupés. A station wagon model based on the van, known initially simply as the "Renault Break 300 Kg" was launched only in 1950. This version, rebranded in 1956 as the "Renault Dauphinoise", would remain in production for nearly a decade after the withdrawal of the saloon/sedan versions of the Juvaquatre, since the rear engined configurations of Renault's post war small cars, the 4CV and the Dauphine made them far less suitable for conversion to the station wagon format than the front engined Juvaquatre. Engine The four-cylinder water-cooled engine with which the Juvaquatre was launched in 1937 (and which continued to power the car till the mid 1950s) shared the 95 mm cylinder stroke of the broadly similar engine that had powered the Renault Celtaquatre since 1934. On the Juvaquatre the cylinder bore (diameter was reduced to 58 mm, however, giving rise to an overall engine capacity of just 1003cc. The engine was a side-valve unit, and at launch a maximum power output of was listed. Significantly, market dynamics dictated that Renault's Juvaquatre was destined to spend more than ten years competing head to head with the Peugeot 202 which from the start came with a more efficient OHV power unit (and more power). The old side-valve unit was finally laid to rest in 1952 and the Juvaquatre Break (estate/station wagon) which was by now the only surviving Juvaquatre version received the smaller 747cc engine from the Renault 4CV. The overhead valve unit produced slightly less power than before, but the Juvaquatre Break was valued for its dependability and low cost rather than for performance, and the new unit came with the bonus of a lower annual car tax bill now that the model was in the 4CV tax band. In 1956 the car moved back up a notch to the 5CV band when it received the bored out version of the same engine fitted at the back of the new Renault Dauphine. The connection with the Dauphine was stressed by the rebranding of the Juvaquatre Break which was now christened the Renault Dauphinoise. The engine size was now 845cc and listed maximum power was up to (SAE). Running gear and brakes Power was transmitted from the
