of Jean Chassagne. A different team of 2-litre dohc 1922 Grand Prix Sunbeams designed by Ernest Henry were entered in that year's French Grand Prix. World land speed record cars He also built a Brooklands racer with a purpose-built V12 18.3-litre engine whose design was a hybrid of the Sunbeam Manitou and the Sunbeam Arab aero engines. This engine had four blocks of three cylinders arranged in two banks set at 60 degrees (unlike the Arab which were set at 90 degrees). Each cylinder had one inlet and two exhaust valves actuated by a single overhead camshaft. The two camshafts were driven by a complex set of 16 gears from the front of the crankshaft – a similar arrangement to that used on the Maori engine which had two OHC per bank of cylinders. This famous car (Sunbeam 350HP) established three Land Speed Records, the first achieved by Kenelm Lee Guinness at Brooklands in 1922 with a speed of 133.75 mph. Malcolm Campbell then purchased the car, had it painted in his distinctive colour scheme, named it Blue Bird and in September 1924 achieved a new record speed of 146.16 mph at Pendine Sands in South Wales, raising it the following year to 150.76 mph. The same year Coatalen's new 3-litre Super Sports came 2nd at Le Mans, beating Bentley – this was the first production twin-cam car in the world. In 1926 Segrave captured the LSR in a new 4-litre V12 Sunbeam racer originally named Ladybird and later renamed Tiger. Coatalen decided to re-enter the LSR field himself, building the truly gigantic Sunbeam 1000HP powered by two Matabele engines. On 29 March 1927 the car captured the speed record at . The car is now at the National Motor Museum, Beaulieu, UK. A later land speed record attempt, with the 1930 Silver Bullet, failed to achieve either records, or the hoped-for advances in aero engines. It is now almost forgotten. Commemoration The name lives on in the open space known as Sunbeam Gardens near a housing estate built in the early 1990s on most of the Ladbroke Grove site of the Clément-Talbot car factory. One of the original buildings remains, the Talbot administration block now known as Ladbroke Hall, with the earl's crest high above its main entrance. In the housing area there is a Sunbeam Crescent.
