Rolls-Royce B range engines

The Rolls-Royce B range was a range of petrol engines first intended to be installed in a car but in 1943 developed into a range to power the British Army's wheeled vehicles.

The range included B40, B60, B80 and B81 versions.

The Alvis Saladin and Rolls-Royce Phantom IV were fitted with 8-cylinder versions.

The group of engineers at Rolls-Royce's Clan Foundry in Belper Derbyshire led by W A Robotham completed development of the Rolls-Royce Meteor engine in 1943 and began work on this rationalised range of petrol engines to power a range of army combat vehicles. Development was completed and manufacture started at Rolls-Royce Crewe in 1947.
