1959 Bentley S1 Continental: One of Nine Style 7500 Mulliner Tailfin Coupes

The 1959 Bentley S1 Continental represents the zenith of the post-war straight-six era, acting as a bridge between the legendary R-Type and the V8-powered S2. As a Continental variant, it was delivered as a high-performance chassis to the world’s elite coachbuilders, with H.J. Mulliner providing some of the most avant-garde designs of the period. This specific example, chassis BC26GN, is one of a reported nine examples featuring the Style 7500 tailfin-coupe bodywork. It stands as a mechanical transition point, showcasing the styling cues that would eventually define the S2 Continental. Currently offered in Switzerland with extensive documentation, this S1 Continental is a rare artifact of British bespoke motoring.

Mulliner Style 7500 Bodywork and Refined Blue Finish

The visual character of this 1959 Bentley S1 Continental is defined by its transition from the classic fastback silhouette to a more modern, three-box profile designed by H.J. Mulliner. Originally delivered with distinctive rear tailfins and triangular front fender peaks, this example was modified during a 1990s refurbishment to feature the smoother lines of the later Style 7514. It is finished in a deep blue that complements the 15-inch steel wheels, which are adorned with chrome covers and body-color rings. Details include Lucas fog lamps, dual side mirrors, and a wrap-around rear window that provides exceptional visibility. The aluminum opening panels ensure that despite its substantial presence, the car retains the lightweight advantage synonymous with the Continental name.

Tan Leather Cabin and Dual-Grain Wood Appointments

Inside, the right-hand-drive cabin offers an environment of unrivaled British luxury, having been re-trimmed in supple tan leather that replaces the factory-specified gray. The interior is anchored by a stunning dual-grain wood dashboard and matching door caps, providing a warm contrast to the color-matched carpeting. Modern comforts were integrated during its South African tenure, including a discreetly installed air conditioning system and a push-button radio. Smiths instrumentation keeps the driver informed, while a three-spoke steering wheel manages the power-assisted system. The cabin remains a sanctuary of quiet refinement, utilizing top-tier materials to ensure that long-distance touring remains a relaxing endeavor for up to four occupants.

4.9L F-Head Inline-Six and Highway-Optimized Gearing

The heart of the 1959 Bentley S1 Continental is its 4.9L F-head inline-six engine, the final evolution of a lineage tracing back to the 1920s. This unit utilizes overhead intake valves and side exhaust valves, breathing through twin SU carburetors to deliver a smooth and torquey power delivery. Continental models were distinguished by an increased 8:1 compression ratio and a higher-ratio rear end, allowing for effortless high-speed cruising. The engine likely produces approximately 178 hp/180 PS and 270 lb-ft/366 Nm, though official figures were famously “sufficient.” Power is managed by a four-speed automatic transmission, while the chassis features electrically adjustable rear shock absorbers to tailor the ride quality to the road surface.

Market Context and the Rare Style 7500 Value

The S1 Continental occupies a prestigious market niche, frequently benchmarked against the Rolls-Royce Silver Cloud I, yet the Bentley variant carries a distinct sporting pedigree. The Style 7500 by H.J. Mulliner is particularly significant due to its extremely low production volume of just nine units, making it far rarer than the standard “Fastback” or the later S2 versions. In the current 2026 market, collectors place a high premium on cars with documented history through the RREC and factory build records. This vehicle’s unique journey through England, South Africa, and Europe, combined with its rare coachbuilt status, provides a unique selling point for investors seeking a documented alternative to more common post-war luxury coupes.

Documented History and European Stewardship

Ownership of chassis BC26GN is exceptionally well-documented, beginning with its delivery to Hansons Buses Ltd. in June 1959. The vehicle is accompanied by copies of its factory build documents, an RREC and SHRMF Certified Copy of a Factory Record, and a Schoellkopf card detailing its early life. Recent mechanical refreshes and invoices from the last seven years ensure that the car remains in peak operating condition. Now offered on dealer consignment in Switzerland with German registration, the car shows just 61,000 indicated miles. This documented provenance, combined with the 1990s refurbishment by Clark & Carter, ensures that the next steward inherits a Bentley with both a rich narrative and a solid mechanical foundation.

A Masterpiece of Bespoke Continental Touring

The 1959 Bentley S1 Continental is a physical manifestation of a golden era in coachbuilding, where performance and luxury were tailored to the specific whims of the individual owner. By merging the last great British straight-six with the exclusive Mulliner Style 7500 bodywork, Bentley created a vehicle that transcended standard production limits. This blue-over-tan example remains a loud, proud, and beautifully preserved reminder of the brand’s heritage as the preferred choice for the discerning driver. Whether navigating Swiss mountain passes or occupying a place of honor in a global collection, this S1 Continental continues to deliver a world-class presence that remains as dignified today as it was in 1959.
