The Vauxhall D-type was a car manufactured by Vauxhall Motors from 1913 to 1922. Many were supplied to the British Army in World War I for use as a staff car.
In 1911 Vauxhall had introduced its C-type which had much sporting success and has become known as the Prince Henry. Many of the C-type cars were fitted with heavy bodies and to better cater for this trade, Vauxhall re-tuned the engine, de-rating the maximum power to 60 bhp (45 kW). The car was marketed as the "weight carrying chassis". Top speed is around 60 mph. The Vauxhall D-type was made before Vauxhall became General Motors and at the time it could beat most of the three litre Bentleys, however in 1925 when Vauxhall was taken over by General Motors the designers got angry and went to work for Bentley. This is why the Bentleys after 1925 were better than the Vauxhalls.
The substantial chassis has semi elliptic leaf springs and rigid axles front and rear. The engine, with fixed cylinder head and bore of 95 mm and stroke of 140 mm, drives the rear wheels via a multi-plate clutch and four speed transmission separated from the engine. The engine, clutch and transmission are mounted on a sub frame. There are no brakes on the front wheels but the car has a transmission brake immediately behind the gearbox operated by the foot pedal. The rear wheel brakes are operated by hand lever inside the car.
About 4500 were made in total including 1556 supplied to the armed forces. It was superseded by the 23/60 OD-type which had an overhead valve engine and four wheel brakes.
