Bentley Continental S1 Fastback by H.J. Mulliner
The 1955 Bentley Continental S1 Fastback by H.J. Mulliner is widely regarded as one of the most beautiful British cars ever produced and among the finest expressions of post-war coachbuilt luxury. The Continental represented Bentley's highest expression of grand touring capability, and the H.J. Mulliner fastback body was the most celebrated of the coachwork designs available.
The S1 Continental was powered by a 4,887cc inline-six engine producing approximately 178 horsepower (Rolls-Royce and Bentley traditionally described their engines' output as 'adequate' rather than providing specific figures). The engine featured an F-head design with overhead inlet valves and side exhaust valves, mated to an automatic transmission. Despite the modest-sounding power output, the engine's generous torque provided effortless acceleration for high-speed continental touring.
The H.J. Mulliner fastback body was designed by chief stylist John Blatchley and built using traditional coachbuilding methods. The aluminum body panels were hand-formed over an ash wood framework, creating a shape of extraordinary grace. The sweeping fastback roofline, flowing rear fenders, and restrained chrome detailing produced a silhouette that has aged beautifully and continues to influence automotive design.
The Continental S1 was designed specifically for high-speed touring across European distances, and every aspect of the car reflected this mission. The higher-geared rear axle ratio prioritized relaxed cruising speed over acceleration. The improved cooling system could handle sustained high-speed driving in warm climates. The more aerodynamic body shape reduced drag compared to the standard Bentley saloon.
The interior was appointed to the highest standards of British coachbuilding, with Connolly leather upholstery, Wilton wool carpet, and polished wood veneers. The craftsmanship was exceptional, with every detail — from the stitching on the seats to the grain-matching of the wood — executed to perfection. The cabin was designed as a sanctuary for comfortable long-distance travel.
Bentley and H.J. Mulliner produced a limited number of Continental S1 fastbacks, making them exceptionally rare today. The car represented the absolute zenith of British craftsmanship in the 1950s and remains one of the most desirable post-war Bentleys. Well-preserved examples command prices well into six figures, reflecting the car's rarity, beauty, and the prestige of the Bentley Continental name.
The Continental S1 Fastback by H.J. Mulliner is not merely a car but an artwork in steel, aluminum, leather, and wood — a rolling expression of the finest traditions of British automotive craftsmanship.
Provenance and documentation are essential at these values. The coachbuilt body should be inspected for structural integrity of the wood framework and condition of the aluminum panels. The engine requires specialist Bentley knowledge for maintenance. The automatic transmission should shift smoothly. Interior trim quality should be assessed by a specialist. A full inspection by a recognized Bentley authority is mandatory before purchase.
The Continental S1 was produced from 1955 to 1959 at the Bentley/Rolls-Royce factory in Crewe, England. Bare chassis were delivered to coachbuilders, with H.J. Mulliner in London being the most prominent. Each fastback body was hand-built using traditional methods.
