The Bentley S1 was built from 1955 to 1959.
The Saloon, the most traded version: The S1 marked Bentley's bold departure from pre-war tradition, introducing unitary construction and modern styling while retaining the marque's legendary refinement. Powered by a robust 4.9-liter straight-six producing 178 horsepower, the S1 delivered effortless grand touring capability with a top speed of 106 mph. Its pressed-steel monocoque body, shared with the Rolls-Royce Silver Cloud, represented a technological leap forward from the separate chassis designs of the R-Type. The S1's understated elegance and superb build quality established the template for modern Bentley luxury. With approximately 3,538 examples produced over four years, finding a well-preserved S1 requires patience, as many suffered from neglect during the marque's less fashionable decades. Today's collectors appreciate the S1 as the foundation of contemporary Bentley DNA—sophisticated, powerful, and distinctly British. Values have steadily climbed as enthusiasts recognize its significance in Bentley's evolution from sporting manufacturer to luxury icon.
