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.

Isotta-Fraschini

Italy, 1900 – 1949

(1) Società Milanese d’Automobili Isotta, Fraschini & Cia, Milan, 1900 – 1904

(2) Fabbrica Automobili Isotta-Fraschini, Milan, 1904 – 1949

Cesare Isotta and Vincenzo Fraschini went into partnership in 1899, importing French cars (Mors, Renault) and proprietary engines (Aster); when their company was floated a year later the first Isotta Fraschini cars to bear their names were thinly disguised Renaults with shaft drive and 5hp single-cylinder Aster power units. A 12hp twin Isotta Fraschini car appeared in 1902, but the first wholly Italian designed Isotta Fraschini cars were not seen until 1903. These new Isotta Fraschini cars followed the fashionable Mercédès idiom with pair-cast 4-cylinder engines, side valves in a T-head, low tension magneto ignition, 4-speed gearboxes and side-chain drive. Initially three Isotta Fraschini carmodels were listed – a 4.180cc Isotta Fraschini 12, a 5.426cc Isotta Fraschini 16 and a 7.433cc Isotta Fraschini 24 – and there were few major changes until 1908, though foot accelerators and high tension ignition came in 1906 on Isotta Fraschini cars, and compressed-air starters were offered briefly in 1907, when the largest Isotta Fraschini carcar in the catalogue was the 11.3-litre Isotta Fraschini Tipo C.

Like FIAT and Itala, theIsotta Fraschini carfirm was quick to recognize the prestige value of racing: in 1905 they built an unsuccessful 17.2-litre machine with gear-driven ohc; in 1907 Minoia won the Coppa Florio with a Isotta Fraschini car; and in 1908 Trucco won the Targa Florio. The last year brought numerous successes in the USA, where 40 Isotta Fraschini cars were sold. By 1906 Isotta Fraschini were Italy’s second-ranking manufacturers, after FIAT, but they were hard hit by the Agadir Crisis, and in 1907 there was a successful takeover bid by Lorraine-Dietrich of France, whose intention it was to integrate the Milan Isotta Fraschini car-factory into their organization. By 1909, however, Isotta Fraschini were independent again and had sold a manufacturing licence to Praga in Prague.

A novelty in 1908 was a 1.327cc racing voiturette with ohc 4-cylinder monobloc engine said to run up to 3.500rpm; this Isotta Fraschini car went into limited production as the FENC type. More important, a successful uncoupled 4-wheel braking system was evolved by Oreste Fraschini and Giustino Cattaneo (who had joined theIsotta Fraschini car firm in 1905 and was to be responsible for all Isotta Fraschini cars up to 1935). This was available on production Isotta Fraschini cars by 1911, and three years later was standardized on the larger Isotta Fraschini cars. The 1909 range included a modern sv monobloc four, the ENC, available in 2.1-litre and 2.2-litre forms, though the old combination of T-head engine and chain drive persisted until 1913. The smaller Isotta Fraschini cars of 1914 closely paralleled the offerings of FIAT and Itala, coming in 2.3-litre, 3-litre and 4.4-litre sizes, with monobloc engines, 4-speed gearboxes, and optional electrics. However, for the enthusiast the Isotta Fraschini car company offered some 16-valve ohc sports cars with 4-wheel brakes and chain drive – the 6.2-litre Isotta Fraschini TM and the 10.6-litre Isotta Fraschini KM. The latter boasted dual magneto ignition, could be had with pear-shaped or V-radiator, and this Isotta Fraschini car was capable of 85-90mph on 140bhp. A Isotta Fraschini car with 130bhp 7.2-litre engine was raced unsuccessfully at Indianapolis in 1913, and there was also a shaft-driven variant of the TM, designated the Isotta Fraschini TC.

After World War 1 Cattaneo switched to a one-model Isotta Fraschini car programme with the Isotta Fraschini Tipo 8, a 5.880cc 9-bearing pushrod ohv straight-8 with alloy block, magneto ignition, 3-speed unit gearbox, central ball change, multi-plate clutch, semi-elliptic springing, and coupled 4-wheel brakes. Output was 80bhp at a low 2.200rpm, and the Isotta Fraschini car was conceived from the start as a chauffeur-driven carriage – hence the ponderous handling that attracted unfavourable comparisons with the contemporary 32CV Hispano-Suiza. Most straight-8s were exported: of 1.370 delivered Isotta Fraschini cars between 1919 and 1935 about 450 went to the United States and there were agencies in eight foreign capitals. In 1925 the Isotta Fraschini Tipo 8 gave way to the 7.4-litre Isotta Fraschini 8A with servo brakes, higher gear ratios, and an output of 110 – 120bhp; the 135 bhp Isotta Fraschini 8ASS sports version was said to do 104mph. By 1929 a Isotta Fraschini carlimousine cost £2.900 in London or $22.750 in New York. Two years later came the last of Isotta Fraschini car with a straight-8, the Isotta Fraschini 8B. This had a redesigned engine capable of 3.000rpm, coil ignition, and a stiffer and deeper frame; from 1932 Isotta Fraschini car was available with a 4-speed preselective gearbox, a conversion initiated by Antione Lago, then the Isotta Fraschini company London agent. In 1934 a 4-speed synchromesh box was offered, but by now sales were down to a trickle (only 25-30 8Bs were made all told, as against 950 8As) and the Isotta Fraschini car company, after unsuccessful negotiations for a merger with Henry Ford, elected to concentrate on aero engines. In 1936 Isotta Fraschini joined the Caproni organization, and their only roadgoing products were diesel trucks made under MAN-licence.

There was a final comeback of Isotta Fraschini cars in 1947 with the Rapi-designed 8C Monterosa – Isotta Fraschini never marketed a six. This Isotta Fraschini car had a 90 degrees ohc V8 engine mounted at the rear of a platform chassis, with independent front suspension by rubber in compression and swing-axle rear suspension. The 5-speed all-synchromesh gearbox incorporated an overdrive top, brakes were hydraulic, and a curious feature was an ignition warning light that went out in the event of trouble. Various cylinder capacities were tried: the 1947 Paris Salon Isotta Fraschini car had a 3.4-litre unit, but production models were to have had 2.544cc engines. Prototype Isotta Fraschini cars wore aerodynamic convertible and closed coachwork by Touring of Milan, but less than 20 Isotta Fraschini 8Cs had been built when the factory was shut down by order of the Italian government. The name Isotta Fraschini was acquired by the Breda armaments firm, who attempted a revival of the diesel commercial vehicle range as late as 1958
