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.

Alfa Romeo

Italy, 1910 to date

(1) A.L.F.A. (Anonima Lombardo Fabbrica Automobili), Milan, 1910 – 1914

(2) SA Italiana Ing. Nicola Romeo & C, Milan, 1914 – 1930

(3) SA Alfa Romeo, Milan, 1930 – 1942

(4) Alfa Romeo SpA, Milan, 1942 to date

(5) Alfa Romeo SpA, Pomigliano d’Arco, Naples, 1971 to date

A.L.F.A. (Anonima Lombardo Fabbrica Automobili) was founded in 1909 by Cav. Ugo Stella, formerly managing director of the Società Italiana Automobili Darracq, to manufacture a completely new range of Italian cars at Portello on the outskirts of Milan where, since 1906, small French Darracq cars had been assembled.

By 1910 the last Darracq had left the factory, and production commenced of a sturdy range of Alfa cars designed from scratch by Cav. Giuseppe Merosi, a native of Piacenza, who had been Chief Technician with Bianchi in Milan.

The first Alfas were a 24hp 4.1-litre car, later known as the 20/30hp, and a 12hp, 2.4-litre, which became the 15/20hp. Both were well made, with side-valve 4-cylinder monobloc engines and shaft drive. In 1913 the sports 6.1-litre 40/60hp appeared with push-rod overhead valves operated by two camshafts in the crankcase. A one-off 4½-litre Grand Prix car was built in 1914 with a 4-cylinder twin ohc engine, but it never ran in international races.

In 1915 the factory was taken over by the industrialist Nicola Romeo, and after World War 1 the pre-war models were marketed as Alfa Romeos. The 20/30 ES Sport of 1921-22 was successful in Italian races, as was a special racing 40/60 driven by Campari, which scored the firm’s first victory at Mugello in 1920. A 6-cylinder luxury side-valve car called the G1 was not a success, but Merosi’s best remembered designs followed it; the 3-litre 6-cylinder push-rod ohv touring, sports and racing RL series cars which first appeared in 1921 and went into production in 1922. A racing version won the 1923 Targa Florio. The similar 4-cylinder 2-litre type RM was marketed in 1923-26, but the pointed radiator sports 22/90hp RLSS and the touring 21/70hp RLT, which had a flat radiator, were sold until 1927.

In 1924 Alfa Romeo won the very first Grande Epreuve they ever entered, an unparalleled achievement, when Campari was victorious in the 1924 French Grand Prix at Lyons in the new straight-eight supercharged P2 car, designed by Vittorio Jano, who came from Fiat. In 1925 Alfa Romeo were declared World Champions. 

Jano took over from Merosi in 1926 and his first touring and sports car designs soon became world famous, these having single and twin overhead camshaft 6-cylinder engines, first in 1.500cc and then in 1.750cc form. When supercharged, these cars won all the great sports car races in the period 1928-1930, with the exception of Le Mans.

The latter omission was rectified from 1931 to 1934 when victory at Le Mans each year went to Jano’s next sports car design, which had a 2.3-litre straight-eight supercharged engine with a central drive to the overhead camshafts. This engine also powered the successful Grand Prix Alfa Romeo of 1931, known as the Alfa Romeo‘Monza’ model and raced for the factory by Scuderia Ferrari. In 1932 this engine, in 2.65-litre form, powered the Alfa Romeo Type B P3 Monoposte G.P. car, which proved virtually unbeatable and bore affinities with the Alfa Romeo Type A racing car of 1931 powered by two 1.750cc engines side by side. In 1933 Alfa Romeo came under State ownership and the Alfa Romeo Monopostos were withdrawn from racing until right at the end of the season. Ferrari continued F.O. racing with Alfa Romeo Monzas enlarged to 2.6 litres.

The Alfa Romeo Monopostos in 2.9-litre form were not powerful enough against the Mercedes and Auto Unions, although Chiron won the 1934 French G.P. for Alfa Romeo, whilst Nuvolari quite unexpectedly won the 1935 German G.P. in an Alfa Romeo 3.8-litre Monoposto fitted with Dubonnet independent front suspension. From 1936 to 1939 Alfa Romeo fielded independently sprung straight-eight, V-12, and V-16 cars in G.P. racing, but against the German cars only isolated victories in smaller races were attained, usually through the skill of Nuvolari. In 1935 Ferrari built two big bi-motore racing cars, with one Alfa Romeo P3 engine under the bonnet and another in the tail.

Some 2.9 P3 engines were put into all-independently sprung chassis in 1937-1939 to make expensive but exceedingly fast prestige sports cars. In sportscar racing Alfa Romeos won every Mille Miglia from 1928 to 1938 inclusive, except in 1931. 

In 1934 Jano’s unsupercharged 6-cylinder twin ohc 2.3-litre car replaced the 1750 and 8C 2300, and, developed by Bruno Treviso, it later became the 2500 of 1939 and the early post-war years. It was recplaced in 1950 by the 4-cylinder 1900. This marked an important change in Alfa Romeo policy. Previously the touring Alfas had been expensive and semi-bespoke machines, whereas the 1900 and its successors were unitary construction saloons whose production has risen to about 30.000 units per annum at the present time. In 1954 was introduced the famous 1300ccc Giuletta, designed by Orazio Satta. From it were derived the successful 1600 Giulia and the 6-cylinder 2600, introduces in 1962. For 1968 the 1600s were replaced by the 1750 series, actually 1.779cc, available as a saloon(Berlina), coupé (1750 GT Veloce) or open sports (1750 Spider Veloce).

The remarkable Colombo-designed supercharged 1½-litre 8-cylinder Monoposto known as the Alfa Romeo ‘158’ was introduces in 1938 for voiturette racing. After the war it was eligible for the Grand Prix formula, and by remaining unbeaten in Grandes Epreuves in 1946-1948 and 1950 until mid-1951, it set up a record unequalled by any other G.P. design. In 1946 Alfa Romeo took the first three places in the G.P. des Nations at Geneva, and repeated this finishing order in 1947 in the Italian G.P., the G.P. d’Europe at Spa and the Swiss G.P.. The most successful drivers during these years were Jean-Pierre Wimille, Achille Varzi and Count Felice Trossi, but the deaths of all three took place before the 1949 season and Alfa Romeo withdrew from racing as they had done in 1933. The Alfa Romeo 158s returned to the tracks in 1950 with Giuseppe Farina and Juan Manuel Fangio as their star drivers, and after victories in every race the cars ran in, Farina was declared World Champion. In 1951 Fangio was World Champion on the 400bhp Alfa Romeo Type 159, though the cars had to concede their first defeat, by and unblown 4½-litre Ferrari. 

At the end of the season Alfa Romeo withdrew from G.P. racing, and although the works Disco Volante sports racing 2½- and 3-litre cars of 1952-1953 were generally unlucky in racing, the Alfa Romeo Giulias have had G.T. successes in recent years.

Competition activities were resumed in 1967 with the Alfa Romeo T33, a rear-engined 2-litre 4ohc V8 with hemispherical combustion chambers, fuel injection, alternator ignition, and a 6-speed all-synchromesh gearbox. Until 1969 a tubular trellis frame was used, replaced for 1970 by an orthodox platform, and the disc brakes were mounted inboard. This Alfa Romeo T33 was catalogued at 9.750.000 lire but was primarily used by the Autodelta racing team; later cars had 2½-litre and 3-litre engines. In 1971 Alfa Romeos won the BOAC 1.000 Kilometers, the Targa Florio and the Watkins Glen 6 hours, but in 1972 they were powerless against the all-conquering Ferraris. In the touring-car range, the six disappeared in 1969, and in 1970 the fuel-injected dry-sump 2.6-litre V8 engine was applied to a conventional front-engined coupé, the Alfa Romeo Montreal.

Other new 1972 models were the Alfa Romeo 2000, an updated 1750, and the 1.750cc Alfa Romeo Alfetta saloon with 122bhp engine, a 5-speed De Dion transaxle, double wishbone independent front suspension, and inboard disc brakes. It was the angular rear-end treatment of Alfa Romeo’s new economy saloon. The Alfasud, made in the Naples factory opened during 1971. This car had a 1.186cc flat-4 engine with cogged-belt drive for its twin overhead camshafts, hypoid bevel drive to the front wheel, all-disc brakes, and four forward speeds.
