still diamond-shaped, but within the diamond the image of a three-masted frigate ("frégate") had been replaced by a tiny outline map of mainland France containing the inscription "RNUR-France". The "Frégate Affaires" offered a price saving of approximately 100,000 francs in return for a reduced specification that involved a simplified dashboard, reduced interior trim, the removal of exterior chrome over-riders from the bumpers as well as the loss of the twin fog lights and windscreen washer which remained a standard feature on the "Frégate Amiral" The launch of a cut-price Frégate was presumably part of the same strategy that was behind the launch of the cut-price 4CV Service. Neither of these stripped-down versions were well received by customers: in the Frégate's case, this was one of several attempts to make the model more competitive that failed to shake Citroën's dominance of the French market for large family cars. In 1956 Renault addressed the complaints about the lack of power from the 2-liter engine by introducing the bored out 2141 cc Étendard engine, which produced . A new, luxurious Grand Pavois trim package was launched the same year. In 1957 a three-speed 'Transfluide' semi-automatic transmission, incorporating a fluid coupling, became an option along with a slightly more powerful version of the 2141 cc engine producing due to a compression ratio increase from 7.0:1 to 7,5:1. The 1958 models saw another modified front grille. The prominent wide chrome oval and horizontal bars were removed to leave only the row of thin bars over which, since 1955, they had been placed. Domaine and Manoir An estate variant, the Renault Domaine was launched in 1956 and was powered by the 2141 cc Étendard engine. A luxury estate, the Renault Manoir was introduced in October 1958, featuring "Transfluide" automatic transmission included in the price. Commercial Citroën reinforced their domination of the market for larger saloon cars in 1955 with the introduction of the futuristic DS, followed in 1957 by its more aggressively priced ID variant. Sales of the Frégate peaked in 1955 with 37,717 cars sold before slumping to 24,608 in 1956 and dropping to 9,772 in 1957: volumes failed to recover as competition from Simca and Citroën intensified in the large car sector through the later 1950s. On 18 April 1960 the final Frégate emerged from the plant, after just 1,158 cars had been built during that year to date. In total, 163,383 Frégates were
