Background
Although Rolls-Royce's acquisition of Bentley Motors in 1931 had robbed the latter of its independence, it did at least ensure the survival of the Bentley name. Launched in 1933, the first of what would become known as the 'Derby' Bentleys continued the marque's sporting associations, but in a manner even more refined than before.
Even W.O. Bentley himself acknowledged that the 3½-Litre model was the finest ever to bear his name.
Based on the contemporary Rolls-Royce 20/25, the 3½-Litre Bentley was slightly shorter in the wheelbase at 10' 6" and employed a tuned (115bhp), twin-SU-carburettor version of the former's 3,669cc overhead-valve six-cylinder engine. Add to this already remarkable package a part-synchromesh four-speed gearbox and servo assisted brakes, and the result was a vehicle offering the driver effortless high performance in almost absolute silence.
'The Silent Sports Car', as it was quickly dubbed, had few peers as a tireless long-distance tourer, combining as it did traditional Rolls-Royce refinement with Bentley performance and handling.
