The Bentley S1, introduced in 1955, represented a seamless blend of traditional British craftsmanship and engineering excellence. Produced until mid-1959, it was the last Bentley to utilize a straight-six engine before the introduction of the V8-powered S2. Characterized by its elegant styling and luxurious appointments, the S1 was typically bodied as a standard steel saloon, featuring a robust stressed steel structure with lighter alloy for the opening panels. This particular 1957 Bentley S1 saloon boasts a unique history, having spent its early years in the UK, a period in the US during the 1980s, and a return to England for a refurbishment in the late 1990s, before being imported back to the US approximately fifteen years ago. Acquired by its current Oregon owner in 2016, this right-hand drive example presents a compelling opportunity to experience classic British motoring with a well-documented past and recent servicing.
This 1957 Bentley S1 saloon is presented in a sophisticated Tudor Grey finish, a shade applied during its late 1990s refurbishment. It is believed to have undergone a color change sometime in the 1980s before being refinished in its current elegant hue. The exterior features classic chrome bumpers with guards, providing a touch of traditional styling, along with functional front fog lamps for enhanced visibility. Dual side mirrors aid in maneuvering, and a rotating roof-mounted antenna adds a period-correct detail. The car rides on 15-inch steel wheels adorned with bright covers, wrapped in Bridgestone Dueler H/T tires, ensuring a comfortable and reliable ride. A spare wheel is neatly stored in a compartment beneath the trunk. The braking system utilizes servo-assisted hydraulic drum brakes, with twin master cylinders managing hydraulic actuation at the front and hydromechanical actuation at the rear, providing a reassuring level of stopping power for a car of this era. A comprehensive brake system refresh in March 2025 included the rebuilds of both master cylinders, thorough cleaning of the wheel cylinders, and a complete fluid flush, ensuring optimal braking performance.
Power and Performance: Under the bonnet of this elegant Bentley S1 resides a refined 4.9-liter F-head inline-six engine. This engine design incorporated overhead intake valves and side exhaust valves, fed by twin SU carburetors, known for their smooth operation and reliable performance. While specific horsepower figures for the 1957 S1’s engine typically ranged around 120-130 bhp, the inline-six provided ample torque for a comfortable and stately driving experience. Power is delivered to the rear wheels through a GM-designed Hydra-Matic four-speed automatic transmission, offering smooth and effortless gear changes, perfectly suiting the car’s luxurious character. The car features an independent front suspension with coil-sprung double wishbones, contributing to a comfortable and controlled ride. The solid-axle rear arrangement utilizes semi-elliptical leaf springs, a traditional setup for the era, providing a balance of comfort and stability. Telescopic shock absorbers have been added at both the front and rear, likely enhancing the ride and handling characteristics. Recent mechanical work in March 2025 also included repairs to the electric fuel pump, an essential service to ensure reliable fuel delivery, along with a routine oil change and the replacement of the battery, preparing the car for its next owner.
The right-hand-drive cabin is trimmed in rich red leather, covering the front and rear bench seats, as well as the door panels, creating a cohesive and luxurious environment. Color-keyed carpeting adds to the refined ambiance, while multigrain wood door caps provide a touch of traditional elegance. Roll-up windows maintain the car’s classic feel, and a dashboard-mounted rearview mirror offers a clear view. Adding a touch of classic sophistication is an under-dash bar fitted with two decanters, along with practical rear trays that fold down from the front seatbacks, offering convenience for rear passengers. A fold-down central rear armrest enhances rear passenger comfort. The three-spoke steering wheel sits ahead of a beautifully crafted wood dashboard, housing Smiths instrumentation, including a 110-mph speedometer and a combination gauge. The five-digit odometer currently shows 88,000 miles, with approximately 20 of those added under the current ownership. This 1957 Bentley S1 saloon, with its right-hand drive configuration, well-documented history, recent mechanical attention, and classic British elegance, offers a unique opportunity to own a piece of automotive history. The car is offered with service invoices from 2025 and a clean Oregon title listing the car as a 1958 model year, a likely clerical discrepancy given the production dates of the S1.
