The 3 1/2 litre started the Derby Bentley Era. Derby is the name of the place where Rolls-Royce had their old factory, and Derby Bentleys are named after the factory where they were built following Rolls-Royce's acquisition of Bentley in 1931. Immediately after the acquisition by Rolls-Royce, true Bentley fans couldn't believe what had happened to Bentley and were heart broken. However the Bentley spirit was carried on, and Bentley's popularity increased due to high performance and better handling, bringing old fans back, and earning Bentley the title of "Silent Sports Cars". This Tourer with Vanden Plas coachbuilt body is known as the most beautiful Derby Bentleys of all.
