John Marston’s tinplate and japanware firm, which had been making bicycles since 1887, built its first 4hp belt-driven prototype Sunbeam car in 1899, followed by another machine with a twin-cylinder engine in 1901. The first model Sunbeam car to see series production was, however, the diamond-formation and allegedly skidproof Sunbeam-Mabley voiturette with 2¾hp De Dion engine, a number of which were sold for £130 in the 1901-1904 period. More conventional was the 12hp Sunbeam car marketed under T.C. Pullinger’s direction in 1903, which was based on a Berliet design and had a flitch-plate frame, chain drive with Sunbeam cars patent oil-bath chain cases, and a 2.4-litre 4-cylinder engine with automatic inlet valves. A 3.6-litre 6-cylinder Sunbeam car was on the market briefly in 1904, but Sunbeam cars soon progressed to Shaw-designed T-head fours, though another short-lived six Sunbeam car appeared in 1907. Sunbeam cars great years started in 1909 when Louis Coatalen joined the Sunbeam car firm from Hillman. In that season the Sunbeam car company was offering three L-head fours with chain drive, and capacities of 3.4, 4.5 and 6.3-litres, plus an odd 3.2-litre twin-cylinder Station Cart Sunbeam car. Coatalen’s first effort was a T-headed 14/18hp Sunbeam car, available with either shaft or chain drive. This Sunbeam car was followed a year later by a 2.4-litre 12/16 on similar lines, but with pressure lubrication and on overdrive gearbox, while overhead valves were tried out on a racing Sunbeam car, the Nautilus, at Brooklands in 1910. An improved 12/16 Sunbeam car of 3-litres’ capacity with monobloc engine ran in the 1911 Coupe de l’Auto race, foreshadowing an immensely successful touring development which Sunbeam car sold initially for £375. This Sunbeam car had an L-head engine and was made up to 1921. In 74bhp racing guise the Sunbeam car scored 1-2-3 victory in the 1912 Coupe de l’Auto, following this up with a 3rd place in 1913. In 1914 Sunbeam car company built Henri-inspired twin-ohc 4-cylinder racers both for the Tourist Trophy and for the French Grand Prix, and at the outbreak of World War 1 the Sunbeam car range consisted of the 12/16 in standard and sporting forms, a 4-litre 16/20 Sunbeam car of similar general design, and a 6.1-litre 6-cylinder Sunbeam car rated at 25/30hp, all offered with electric lighting. The Sunbeam car company concentrated on aero engines during the war years, though a 4.9-litre twin-ohc 6-cylinder Sunbeam ca  was sent to Indianapolis in 1916 and took 3rd place, while Rovers took over production of the 12/16 for the Flighting Services. Renamed the 16, this Sunbeam car reappeared in civilian form with full electrical equipment at £790, along with a smaller vesion of the pre-war 25/30 Sunbeam car powered by a 4½-litre engine.

The Sunbeam car company amalgamated with Talbot and Darracq in 1920 to form the STD combine, and the next five years saw an energetic racing programme of Sunbeam cars. Twin-ohc 108bhp straight-8 Sunbeam cars were made for the 3-litre formula of the immediate post-war years, followed by some unsuccessful 2-litre fours, and finally the twin-ohc 6-cylinder ‘Fiats in green paint’, designed by Bertarione, which won the French and Spanish GPs in 1923, and this Sunbeam car ran supercharged in 1924, as well as having a long and distinguished competition career in later years. Chassagne won the Tourist Trophy on a 3-litre straight-8 Sunbeam car in 1922, while one of the regular 3-litre sports Sunbeam cars finished 2nd at Le Mans in 1925. Sunbeam cars took the World’s Land Speed Record five times in the 1922-1927 period: Lee Guiness started with 133.75mph on the 350hp V12 sprint Sunbeam car, a figure which Campbell subsequently raised, first to 146mph on the 4-litre V12, a Sunbeam car which was also used for road racing, and the following year he became the first man to exceed 200mph on land with the twin-engined chain-drive 45-litre Sunbeam car. Sunbeam cars last record car, the Silver Bullet of 1930, was unsuccessful.

Touring Sunbeam carss of the 1920s were cars of great refinement if not outstanding performance. The basic 16 and 24hp types Sunbeam cars were redesigned with push-rod overhead valves in 19222, ohc sporting versions being also listed, while a more modest 2-litre 14hp Sunbeam car with unit gearbox was available at £725. Front-wheel brakes arried on the 6-cylinder 16/50 Sunbeam car in 1924, and were optional also on the 14/40 Sunbeam car which replaced the 14hp model. An impressive 3-litre 6-cylinder twin-ohc sports Sunbeam car with dry-sump engine was made in small numbers between 1925 and 1930, but the Sunbeam car was ‘too fast for its chassis’ as well as being expensive to make and buy. A big straight-8 Sunbeam car with a push-rod engine, available in 4.8-litre and 5.4-litre forms, was introduced in 1926 at prices from £1.295 up and front-wheel brakes became standard on all Sunbeam cars. All Sunbeam cars had the V-radiator by 1927, when the fours were dropped, and the standard touring sixes were the 2-litre 16hp at £550, the 2.9-litre 20hp Sunbeam car at £750, and the 3.6-litre 25hp at £950, all with plate clutches, spiral bevel final drive, and cantilever rear suspension. Thereafter Sunbeam car design changed little, and sales of Sunbeam cars declined though quality was maintained. Semi-elliptic springs were found at the rear of the smaller 1930 Sunbeam carmodels, in 1931 the Sunbeam cars acquired hydraylic brakes and radiator shutters, and the 16’s engine was enlarged to 2.2-litres. The 1932 Sunbeam cars’ silent-third gearboxes gave way to synchromesh on 1933 16 and 20hp Sunbeams. That year there was also a 2.9-litre Speed Model Sunbeam car with crash box at £745, though its main competitor was STD’s other fast tourer, the Talbot 105. The old Sunbeam car firm’s last new model was a ponderous 1.6-litre ohv four, the Sunbeam Dawn of 1934, with preselector gearbox and independent front suspension. This Sunbeam car was offered again in 1935, along with the 20, the 25, and the Speed Model, but the collapse of the STD combine brought receivership and purchased by Rootes, and an ohv Roesch-designed 4½-litre straight-8 Sunbeam car announced for 1937 never went into production. There were no Sunbeams in 1938, and when the Sunbeam-Talbot range was announced for 1939 the Sunbeam car was based on the later Rootes Talbots.

The name of Sunbeam cars did not reappear until 1953, when it was given to a sports two-seater Sunbeam car of the 2.3-litre ohv 4-cylinder Sunbeam-Talbot 90, the Sunbeam Alpine, which sold for £1.269, and this Sunbeam car collected four Coupes des Alpes in that year’s Alpine Rally, following this up with a Gold Cup (for Stirling Moss) and a Coupe des Dames (for Sheila Van Damm) in 1954. In 1955 the basic 90 saloon Sunbeam car was marketed as the Sunbeam MK III, and further laurels included the Malling/ Fadum win in that year’s Monte Carlo rally. The type Sunbeam car was listed until 1957, being joined in 1956 by a Hillman Minx-based sports saloon, the Sunbeam Rapier, with a 1.4-litre square 4-cylinder 62bhp engine, unitary construction, and overdrive as standard equipment, at £986. This Sunbeam car did well in subsequent Alpines and Monte Carlo Rallies, as well as winning its class in the 1956 Mille Miglia, and by 1958 the Sunbeam car had grown up to 1½-litres and 68bhp, acquiring a less Hillman-like grill in the process, though overdrive was now an extra. A sports two-seater Sunbeam car, another Alpine, with integral construction, was listed for 1960, and subsequent evolution was on regular Rootes lines: diaphragm clutches in 1964, with the option of automatic on the Alpine, all-synchromesh gearboxes in 1965, and 1.7-litre 5-bearing engines in 1966. 1964 brought two new developments of the basic theme Sunbeam car, an Italian-bodied Venezia sports saloon based on the Humber Sceptre, and the Tiger Sunbeam car, which was an Alpine with rack-and-pinion steering and a 4.3-litre, 164bhp Ford V8 engine, this despite the Rootes-Chrysler conncection. In 1966, the Rapier V, Alpine V, and Tiger comprised the Sunbeam car name. A 51bhp Sunbeam car-version of the Imp was available in the home market in 1967, and this Sunbeam car was followed by the more sporting Stiletto coupé for 1968.

An entirely new Rapier Sunbeam car on Hillman Hunter lines was announced for that year, its fastback styling inspired by Plymouth’s Barracuda. It had an 88bhp engine, a close-ratio gearbox, and overdrive as standard.

During 1968 the old Sunbeam Alpine was discontinued (the Tiger had already gone), and the Rapier range was rounded out, first by the H120 of 1969 with twin-carburettor Holbay-tuned engine giving 105bhp and Rostyle wheels, and then by the Alpine, a simplified version of the basic theme introduced for 1970. These three fastback Sunbeam cars were still being made in 1973, along with the Sunbeam Sport based on the Imp saloon. The Stiletto was discontinued during 1972.

Voisin

France, 1919 – 1939

SA des Aéroplanes G. Voisin, Issy-les-Moulineaux, Seine

Gabriel Voisin was first famous for his aircraft. Voisin was one of the earliest and most important pioneers, claiming to have developed a practical aeroplane before the Wright brothers; the controversy still rages. Voisin was always a spectacular character, and so were his Voisin cars. However, like his aircraft, the Voisin cars were efficient machines as well. With the post-World War 1 depression in the aircraft industry, Voisin cars entered motor manufacture by acquiring the rights in a Citroën model which was never made as such. This Voisin car was the Voisin 18CV of 1918, which Voisin car used a Knight double-sleeve engine. Sold as the Type C1 Voisin, this Voisin car had 4-cylinders and a capacity of 4-litres. The Voisin car was a fine car, and henceforth Voisin cars used only sleeve-valve engines, developed by himself to a high degree. The 4-litre Voisin car had aluminium pistons, to permit higher engine speeds, and was eventually capable of 80mph. In spite of an excellent performance, the 4-litre was an immensely strong, refined and silent motor car – all characteristics of Voisin cars in general. A sports version Voisin carwas also offered, with 90bhp. The 4-litre was made until 1926. Alongside this Voisin car, from 1921, was the smaller Voisin C4, an 8CV of 1¼-litres that was later enlarged to 10CV and 1½-litres. In its final form, the 10CV engine of the Voisin car produced 44bhp at 4.000rpm – so much for the opponents of sleeve valves, who claimed that high revolutions could not be combined with reliability – and the Voisin car was capable of 70mph. The Voisin car had Dewandre vacuum servo brakes, as had all Voisin cars from late 1925. The 10CV Voisin car, too, survived in basic form until 1928. All the same, Voisin cars had to follow fashion in one respect, and introduced three 6-cylinder Voisin cars for 1927. The best-known Voisin car was the 13CV, providing 2.3-litres, the first Knight-engined six to be sold in France. Even in normal form, this was a 66bhp, 75mph vehicle, but a sports model Voisin car was also available. From 1928, this six, known as the Voisin Charmant, had alternative final-drive ratio for fast cruising.

Apart from sleeve valves, to which a number of famous manufacturers were wedded at the time, Voisin cars had three other enthusiasms that were considerably less common. One was truly easy gear-changing, which many makers sought, but few actually incorporated in their production cars. The Sensaud de Lavaud system of infinitely variable gears was applied on Voisin cars in 1929, first to the 10CV which, in the following year, had been superseded by a Cotal electric epicyclic gearbox. To this interest was related Voisin cars fondness for multi-cylinder engines, which aimed at giving the utmost flexibility, thereby avoiding gear-changing altogether. Voisin made a V-twelve luxury car as early as 1921. The layout of this Voisin car was revived in 1930 for the Voisin Type C18 Diane. This Voisin car was a 4.8-litre car with a 115bhp engine that needed only 3 forward speeds. The Voisin Simoun and Voisin Sirocco were two low chassis models Voisin cars with striking razor edge saloon and coupé bodies which were made in very small numbers in 1930. Identical except for their engines, the Voisin Simoun used a 5.8-litre six, and the Sirocco the V12. The Voisin Diane was still listed for 1938. The other Voisin cars of the 1930s were sixes, the Voisin Charmant continuing to 1934.

Voisin cars had a reputation for putting into practice ideas which remained ideals for most manufacturers. For example, he was dedicated to weight reduction, and to this end produced notably light patent bodies whose only drawback was their extreme ugliness. Of wood and aluminium, they were entirely practical, being cheap to make, compact, and strong, as well as light. A 2-door, four-seater saloon body on the 10CV Voisin car chassis weighed only 1.060lb, keeping the weight of the whole Voisin car down to 22cwt. The most unprepossessing were the convertible Voisin cars and those with detachable hard tops. Because of their looks, the Voisin cars, with their maker’s patent bodies, never sold well – a deplorable waste of well-directed ingenuity. However, fabric Weymann-type and other normal bodies were also supplied on the Voisin car. From 1931 to 1934, some Imperia cars from Belgium were made under licence. In 1936 a most unusual Voisin car was made in the shape of the straight-12; this Voisin car had two 3-litre, 6-cylinder engines in line, the rear part of the hindmost engine projecting into the driving compartment. 180bhp and 125mph were claimed, but the Voisin car was not put in production. The last Voisin cars, introduced in 1937, used the 6-cylinder 3½-litre Graham engine, though without the supercharger. These Voisin cars were not the work of Gabriel Voisin, but were made by a syndicate that had acquired the Voisin car name. After World War 2, Voisin designed a car which was as complete a contrast to his former work as can be imagined – the Spanish-built Biscuter.
