Bentley S Specs, Engines & Dimensions (1955–1959) — First Generation
The first-generation Bentley S is a luxury Coupe and Sedan built around a large gasoline automatic and rear-wheel drive. Both bodies are about quiet, long-distance travel rather than sporting pace.
A Bentley S engine in the 4.9 AT examples is a sizable gasoline unit matched to an automatic transmission. Coupe and Sedan share that rear-drive powertrain, so both feel unhurried and touring-oriented; these named versions are selected illustrations, not every drivetrain offered.
