The Sunbeam Tiger was a racing car of the 1920s, built by Sunbeam of Wolverhampton. It was the last car to be competitive both as a land speed record holder, and as a circuit-racing car. cite book

Design and engine

The chassis and bodywork of the Sunbeam were conventional for racing cars of their time.

The car's novelty lay with its engine. Sunbeam's 1925 Grand Prix engine had been a successful 2 litre straight-6 twin-overhead-cam. This car was to use a pair of the same block and head arrangements, mated to a single 75° vee crankcase to for a 3,976cc V12. Supercharging brought the power up to 306 hp.

Land Speed Records

Henry Segrave was so keen to test the new car and engine that he took it to Brooklands in September 1925, still unpainted. A half-mile speed of 145 mph was recorded. Minor works, including the bright red paint still notable today, were done over the winter.

Spring 1926 saw Segrave on the wide, flat beach at Southport. On 16th March 1926, with little fuss and few spectators, he and the bright-red car now named 'Ladybird' set a new land speed record at 152.33 mph. This was also the smallest-engined car ever to hold the Land Speed Record.

Racing

At the time of the land speed record attempt, the car was fitted with a narrow inlet cowling over the radiator,cite web

"Tigress"

One sister car to Tiger was built and named "Tigress".

It survives today, fitted with a Napier Lion engine and racing in British Vintage events as the "Sunbeam-Napier".

In 1990, the now 65 year old Tiger re-created its record attempt, and succeeded in beating it at 159 mph.cite web

The 'Tiger' name

In 1964 and 1972 the "Tiger" name was revived within the marque, first for a V8 version of the Sunbeam Alpine, the Sunbeam Tiger. Later it appeared on the more mundane , which resembled a tiger by being orange with black stripes, if little else.
