The Bentley 4¼ Litre was introduced in 1936. The 4¼ Litre was essentially a Bentley 3½ Litre, but fitted with a larger 4.25L inline six engine. As was the standard at the time, Bentley sold the 4¼ Litre as a rolling chassis, and the bodywork was created by a coachbuilder of the owner's choosing. The Bentley 4¼ Litre was in production until 1939.
