1923 Sunbeam Grand Prix Race Car

The 1923 two-liter Sunbeam, which became the first British racing car ever to win an Grand Prix, has been referred to as "the Fiat in green paint. "for some observers believed it shared many features with the 1922 Fiat Grand Prix racer. Actually any similarities originated with the man the sunbeam motor Company of Wolverhampton, England, hired to design its 1923 Bertarione had designed the highly successful Fiat type 804 Grand prix racer.

The 1923 sunbeam had a six-cylinder, in-line engine with a total displacement of 1,988 cubic centimeters. With two overhead camshafts operating two valves per cylinder, the engine produced 102 horsepower of 5,000 rpm. Drive was through a three-speed gearbox and an open final shaft, and the car had a maximum speed of just under 110 miles per hour.

After they were successfully tested at England's Brooklands circuit, four 1923 sunbeams were shipped across the channel. Then they were driven to the French Grand prix circuit at Tours under their own power.

The cars to beat at Tours were those same supercharged eight-cylinder Fiat Type 804s designed in 1922 by Bertarione. The Fiats were clearly faster than the Sunbeams, as they convincingly proved during the early stages of the race. But, one by one, the Italian cars dropped out of the running, their supercharges clogged with the dirt thrown up by the cars they passed along the way. As the Fiats fell by the wayside, a Sunbeam driven by Kenelm Lee Guiness became the first British car ever to lead a Grand Prix.

In the  end, a sunbeam driven by the famed Henry Segrave was first across the finish line, covering the 496-mile distance at an average speed of 75.3 miles per hour. Two other sunbeams finished in second and fourth places. Later in that same year, Albert Divo won the 248.5-mile Spanish Grand Prix in a two-liter Sunbeam. Divo s' victory turned out to be the last major Grand prix win for a British-built car for more than 30 years.

Sunbeam returned to Grand prix racing in 1924 with cars quite similar to the racers they entered during the 1923 season. A four-speed transmission had replaced the three-speed gearbox, and the cars were slightly longer and wider in wheelbase and track. They had also gained about 300 pounds in weight. The big improvement, however and raised top speed to 125 miles per hour.

Although they were competitive, the 1924 sunbeam were not winners, and the firm gradually lost interest in international racing. Segrave's victory at Tours remains Sunbeam's greatest moment in Grand Prix competition.
