In 1952, Bentley boosted the size of its engine to 4566cc in the so-called “big bore, small boot” models. The company also rectified the “small boot” criticism with “R” Type chassis, whose wheelbase remained 10 feet but whose overall length was extended eight inches at the rear, to create a useful luggage space.
GM’s four-speed Hydra-matic automatic transmission became available on the R-Type in 1953, and was soon standardised. The model's new welded box chassis was strengthened by cruciform bracing, central lubrication was standard, and the ride stiffness could be adjusted via a column lever. Standard accessories included a radio, a heater, a fitted tool kit, leather upholstery, and a sunroof. In all 2,320 R-Types would be built during the car’s four years of production.
Meanwhile, in 1951, the prototype Bentley R-Type Continental was developed, finally to go into production in 1953. The R-Type Continental coupe was a throwback to the fast 1930s Bentley tourers, being lower and sleeker than the saloons, with a curved windshield and streamlined form, a long swooping tail, and rear wing skirts. At its introduction, the R-Type Continental was the fastest four-seater in the world with a top speed of 120 mph. The 4.5-litre engine would be increase to 4.9 litres in 1955 and the close-ratio four-speed gearbox was offered as both floor- and column-shift.
A total of 208 Bentley R-Type Continentals were built, including the prototype. Most were bodied by H.J. Mulliner with five by Park Ward. All but 16 had the distinctive fastback. These cars remain the most desirable post-war Bentley, and were replaced by the S-Type Continental in 1955.
R-Type Bentleys are reasonably common, quite functional, and extremely elegant, but rust is the big enemy of the Standard Steel bodies. As always, full provenance is essential, with as few owners as possible. Bentley records are quite thorough, which is helpful. Cars may have had wedding service — this can be a two-edged sword, as they may have racked up larger miles but may also have been well maintained.
