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.

Franklin

US, 1901 – 1934

(1) H.H. Franklin Mfg Co, Syracuse, N.Y., 1901 – 1917

(2) Franklin Automobile Co, Syracuse, N.Y., 1917 – 1934

Probably the world’s most successful air-cooled car before the advent of the Volkswagen, the Franklin inspired an intense make-loyalty. H.H. Franklin had founded a factory for the manufacture of die castings in 1895, and in 1901 he was introduced to John Wilkinson’s air-cooled designs by Messsrs Brown and lipe, later well known as manufacturers of proprietary transmissions. The New York Motor Co had already made three prototypes before the first Franklin car went on sale in 1902. These Franklin featured transversely-mounted 1.7-litre 4-cylinder air-cooled engines – the valves were overhead, with mechanically operated inlet valves from 1905 – float-feed carburetors, 2-speed planetary gearboxes, central change, full-elliptic suspension and the wooden frames which were to be standard on all Franklin cars up to the end of 1927. A push-on handbrake was used until 1906. Although a Franklin version with water-jacketed engine was projected, the Franklin company remained faithful to air-cooling until they closed down. Sales rose from 13 in 1902 to 184 in 1903, when wire wheels gave way to the wood artillery type, and in 1904 a Franklin broke the San Francisco-New York record. The transverse-engined Franklin cars were catalogued until the end of 1906, but from 1905 onwards new Franklin models with conventionally-located engines made their appearance. These had auxiliary exhaust valves, shaft drive, 3-speed sliding-type gearboxes and round bonnets modelled on the Delaunay-Belleville. A 4-cylinder Franklin sold for $1800, but there was also a 6-cylinder Franklin Model H with a 7-bearing crankshaft and a 9ft 6in wheelbase for $4.000: all subsequent 6-cylinder Franklin cars had seven main bearings. A straight-8 appeared without success in the 1905 Vanderbilt Cup Eliminating Trials. Franklin’s full-elliptic suspension was continued. This gave an excellent ride and resulted in tyre mileages in the region of 20.000: this is why the Franklin company was refusing to fit detachable rims as standard equipment as late as 1922. In 1907 an automatic advance-and-retard was fitted on the Franklin and in 1908 a gear-driven fan. The 1910 Franklin cars used a suction-driven sirocco fan incorporated in the flywheel. Smallest of the 1909 range was the 18hp Franklin Model G, a 2.3-litre 4-cylinder car with quadrant change sold at $1850. Selective change was used on the bigger Franklin fours and sixes which had oversquare cylinder dimensions and cost $2800 and $3750 respectively. With the 1912 Franklin models came a Renault-type bonnet and full pressure lubrication, and a 4-cylinder was still available at $2.000, or $1.500 less than the big 38.4hp 6-cylinder.

In 1914 only a 6-cylinder car, the ‘Franklin 6/30’, was offered, and Franklin fell into line with the rest of the American industry by going over to left-hand drive, central change and full electrical equipment. A year later aluminium pistons were adopted. A stunt drive by Franklin from Walla Walla, Washington, to San Francisco in bottom gear demonstrated the car’s ability to keep cool. The 1917 models had electric chokes, while imitators arose in the industry to try and cash in on Franklin’s success with air-cooling. One of these firms, Holmes, was headed by former vice-president of the Franklin Automobile Co. By the end of World War 1 a 6-cylinder Franklin could be bought for $2.050, reduced two years later to $2.000. 8.648 Franklin cars were sold in 1920. Late in 1922, came a redesigned Franklin car with a ‘horse-collar’ bonnet allegedly modelled on the Fiat, pressure air-cooling with frontal blower, unit gearbox, single dry-plate clutch, 6-volt instead of 12-volt electrics and detachable rims. Sales rose to 11.000 and the Franklin company which had pioneered series-production closed cars as early as 1913 was offering a Franklin sedan at $2.850. During 1925 the design was face-lifted once again and the De Causse-styled Franklin Series 11 introduced. Cylinder capacity remained a modest 3.3-litres, but appearance was entirely changed with a 9ft 11in wheelbase and a vertical-barred ‘radiator’. This revolutionary step so appalled John Wilkinson that he resigned from the Franklin company forthwith. Some of the semi-custom body styles – especially the boat-taled sports coupé at $3.150 – were remarkably attractive. Subsequently some excellent and expensive custom bodywork was designed for Franklin by such firms as Derham, Willoughby, Holbrook, and (especially) Dietrich. Over 13.000 Franklin Series 11s were sold between mid-1925 and the end of 1926, among those who favoured Franklins being Colonel Charles Lindbergh. Yet even the ‘Franklin 11B’ of 1927 retained the wooden frame, full-elliptic suspension and foot transmission brake. Front-wheel brakes did not arrive until the introduction of the 1928 3.9-litre Franklin Airman, which boasted internal-expanding Lockheed hydraulics at a time when the contracting type was generally favoured in America. In 1928 long-chassis models were given steel frames, standardized in 1929, and a standard sedan sold for £885 in England. All but the cheapest Franklin cars now had silent 2nd gearboxes. This was the period in which Dietrich introduced their delightful speedster (actually a 4-door convertible sedan) and a 4½-litre 6-cylinder Franklin engine actually took to the air in a Waco biplane. Prices were generally in the $2.200 - $3.500 range, with custom Franklin models running up to $7.200.

The 1930 Franklin Series 14 introduced a new radiator and side-blast cooling, an the elegant Pirate models had concealed running-boards as well. The unconventional, however, could no longer sell in America, and only 2.851 Franklin cars were delivered in 1931. In 1932 came synchromesh, free wheels and ‘Startix’ devices, as well as a magnificent Dietrich-styled 6.8-litre supercharged V12 (Franklin Series 17) on a 12ft wheelbase. Unfortunately this was re-engineered to incorporate proprietary axles and semi-elliptic suspension, and in production form it weighed nearer three tons than the two tons of the prototype. It combined elegance, 95mph, and 150bhp for $4.400, but few were sold, though a dratic price cut to $2.885 was made for 1933. The last new Franklin was the Franklin Olympic, an inexpensive 6-cylinder using a Franklin engine wedded to a REO chassis and body. The Franklin factory closed down in 1934. The patents were, however, taken over by the Air-Cooled Motors Corporation (now Franklin Engine Co.), whose Syracuse factory has specialized in light horizontally-opposed aircraft engines: a 6-cylinder Franklin helicopter engine, converted to water-cooling, powered the Tucker of 1947. 2-, 4-, and 6-cylinder untis up to 5.7 litres’ capacity were being produced in 1972.
