On Cummins' stand at this year's Goodwood Festival of Speed (from 1^st July) visitors can see a recreation of the famous Napier Railton racing car, one of the few inter-war period racing cars sill running.

The Napier Railton Special is powered by Napier Lion XI gasoline aero engine used in the First World War. The engine has 12 cylinders in three banks of four arranged in a ‘W’ or broad arrow configuration. With a total capacity of 24 litres it has a rated power of 530bhp at 2,350rpm. Using double overhead camshafts it has four valves and two spark plugs per cylinder.

The car was designed by Reid Railton and built by Thomson and Taylor on the Brooklands site. It was first raced in August 1933 by John Cobb and is now based in the Brooklands Museum. It broke the Brooklands outer circuit lap record of 143.44mph in 1935 and set the 24 hour record of 150.6mph at the Bonneville Salt Flats in 1936.

Their prestigious history doesn't preclude higher insurance, so make sure you shop around a few car insurance quotes before committing.
