Bentley S 1 Classic Cars for Sale

Introduction and History of the Bentley S 1

Launched in 1955, the Bentley S 1 replaced the R-Type and marked a pivotal move for Bentley's luxury saloon segment. The model mirrored the Rolls-Royce Silver Cloud in almost every technical aspect and was produced alongside it. Distinguishing itself from its predecessor with a longer wheelbase, lower build, and larger boot, the S 1 repositioned Bentley within the postwar luxury market. Crafted in England at Crewe and released primarily as a four-door Standard Steel Saloon, the model introduced a host of technical refinements, including improved brakes and steering. Beyond standard saloon models, exclusive Continental versions—coachbuilt by the likes of HJ Mulliner and Park Ward—brought bespoke craftsmanship and superior performance to select clients. Production concluded in 1959, replaced by the S2 with V8 power.

Model History

The S 1 was the first in Bentley’s S Series (followed by S2 and S3 until 1965), succeeding the R-Type and preceding the V8-powered S2. Available as a standard saloon or Continental chassis, the model introduced options such as long wheelbase (LWB) variants from 1957, with only 35 built, several wearing bespoke bodies from renowned coachbuilders. Continental versions were built for superior performance and exclusivity, resulting in varied coupé and cabriolet designs. The Bentley S 1 platform saw very limited changes during its four-year production, focusing on incremental improvements and luxury customisation. S1 shares its technical underpinnings and design language with the Rolls-Royce Silver Cloud I, the main differences being the grille and badging.

Highlights and Unique Features

The S 1 distinguishes itself through its refined engineering—the robust 4.9-litre inline-six engine provides near-silent, effortless cruising, while the suspension and brakes were advanced for their time. Over 90% of S1s featured factory steel saloon bodies, augmented by a small batch of highly prized coachbuilt Continentals, with lightweight aluminium bodies and unique design touches. In addition to its technical pedigree, the S1’s cabin set new standards for luxury, with walnut dashboards, thick leather, and details like picnic tables and optional air conditioning available from 1957.

Technical Data

Special Editions and Collectible Models

The S1 Continental represents the pinnacle of exclusivity within the series, featuring lightweight aluminium coachwork—mostly as coupé or convertible—executed by HJ Mulliner, Park Ward, and others. Only 431 Continentals were produced, for selected clients, including a mere 31 left-hand-drive Park Ward Drophead Coupés and 49 HJ Mulliner Flying Spur models. LWB saloons with bespoke coachwork—such as those by Hooper or James Young—are exceedingly rare, with just 35 LWB chassis completed.

Weak Spots and Common Issues

No specific model-related issues are reported within supplied data, but prospective buyers should scrutinise the condition of hydraulic drum brakes, electrical systems, and ensure regular servicing of the six-cylinder engine—particularly carburettor balance and cooling system integrity. Attention to rust on steel-bodied saloons, and detailed inspection of coachbuilt aluminium panels for corrosion, are recommended. Ensure originality of the interior, as restoring high-grade walnut and original leather can involve substantial costs.

Engine and Performance, Transmission and Handling

The S 1’s 4.9-litre straight-six delivers a refined and nearly silent drive, particularly when combined with the Hydramatic four-speed automatic transmission. Road test figures from 1957 indicate a 0–100 km/h sprint in approximately 13 seconds and a maximum speed of 166 km/h. The long-travel suspension and robust chassis provide outstanding comfort and precise handling for a vehicle of this size, with LWB versions known for exceptional rear-seat comfort. Continental variations benefit from higher compression, lightweight bodywork, and distinct coachbuilt dynamics. - S1 Standard Steel Saloon: The staple model, combining robust engineering with understated British luxury.

• S1 Continental by HJ Mulliner/Park Ward: Custom chassis and light-alloy bodies, significantly improved acceleration and agility.
• LWB Coachbuilt Saloons: Ultra-rare variants offering unique styling and even greater interior space.

Interior, Comfort, Exterior and Design

The S 1’s exterior design prioritises elegance with restraint: flowing lines, subtle chrome, and an assertive Bentley grille create dignified presence without excess. Customers could specify exterior colours or select unique hues, especially on coachbuilt Continentals. Inside, S1s featured fine walnut dashboard and door cappings, deep-pile carpets, premium hides, and optional extras such as air conditioning (from 1957), electric windows, and rear picnic tables. Special-order cars were often equipped with further custom accessories—left- or right-hand drive, radios (HMV, Philips), and innovative comfort elements. Coachbuilt models offered almost limitless personalisation, including bespoke trim, detailing, and handcrafted finishes.

Other Notable Features

The Bentley S1 was aimed at high-level clientele, including British industrialists, aristocrats, and celebrities—reflected in both the standard of craftsmanship and level of customisation. Import versions, especially LHD configurations for the US market, are less common and attract substantial interest. Today, the S 1 remains a reference point for quiet British prestige and the enduring value of handcrafted luxury.

Summary

The Bentley S 1, produced just 3,538 times from 1955–1959, stands as the archetype of British luxury saloons in the 1950s. Technically advanced, meticulously built, and fully customisable, the S1 excels not only for its dependable six-cylinder engine and supple ride, but also for its unique position bridging traditional craftsmanship and postwar modernity. Collectors and enthusiasts searching for a luxurious yet usable classic, especially with rare coachbuilt bodies, will find the S1 a distinctly British answer to postwar automotive refinement.
