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.

Lagonda

GB, 1906 – 1963

Wilbur Gunn, the founder of the Lagonda Car Company, hailed over Springfield, Ohio. He came to England in about 1897. In 1898 he built an air-cooled cycle in a greenhouse at Staines. On this site the first vehicle to bear the Lagonda car name was assembled in 1900, an improved version of the air-cooled cycle; and it was here that Lagonda cars were to be built until 1947.

To his new product, the Lagonda car, Gunn gave the French form of the American Indian name for Buck Creek, the stream near his home town. In 1905 the Lagonda car company’s first racing success came when a V-twin cycle won the London-Edingburgh trial. This victory encouraged Gunn to enter the motor car field with a 20hp 4-cylinder Lagonda car. Developed in 1906, this first Lagonda car was brought out the following year as the Lagonda Torpedo. A 6-cylinder version followed; the Lagonda car carried Wilbur Gunn and Bert Hammond to win the Moscow – St Petersburg Reliability Trial in 1910. The big tourer Lagonda car was a result ‘greatly favoured’ by Tsar Nicholas II, and the Lagonda Car Company’s early fortune was made form exporting these Lagonda cars to Russia until war broke out in 1914.

At home a dapper Lagonda 14/4 replaced the earlier Lagonda 12/4 in 1909. This gave way in 1913 to an 11.1hp light Lagonda car of radically advanced design. Among its more striking innovations were a riveted monocoque body of unit construction; an anti-roll bar to assist the suspension; and the Lagonda car had the earliest known fly-off hand brake. The Lagonda car enjoyed a wide market, being subsequently enlarged into a 11.9 in 1920 and a 12/24 in 1924, though later Lagonda cars no longer had monocoque construction.

In 1925 Arthur Davidson designed the 1954cc ohv-engined Lagonda car which marks the beginning of the Lagonda as a sports car. The Lagonda 14/60 engine featured 4-fully-machined hemispherical combustion chambers, the first to be marketed, aspirated by interchangebale valves opposed at 90 degrees. Twin camshafts were carried high in the block of the Lagonda car. A Rubury braking system of prodigious efficiency was fitted. Grouped chassis lubrication nipples were featured, as was a clutch stop. The whole Lagonda car was superbly finished.

The Lagonda 2-litre Speed Model, a modified version of the 14/60 Lagonda car, was developed late in 1927 for the 1928 season. The chief difference between it and the earlier Lagonda car lay in the valve-timing overlap, twin carburetors on a direct manifold, and a raised compression ratio of 6.8:1. These alterations combined to give the Lagonda Speed Model tourer an acceleration from rest to 80mph in 50 seconds, and the new Lagonda car did well in competition. A 2½-litre 6-cylinder Lagonda car with push-rod operated ohv was introduced in 1926, and this was subsequently enlarged to 3-litres on Lagonda cars in 1928. For 1930 the chassis of the Lagonda 2-litre was lowered and during that year a supercharged Lagonda car became available. In 1932 came the last of the 4-cylinder 2-litres Lagonda cars, the Lagonda Continental, which had smaller wheels and a sloping radiator, and this finally gave way to the Lagonda 16/80, a 2-litre six with a push-rod operated ohv engine of Crossley manufacture. This Lagonda car was later fitted with an ENV preselector gearbox. This was an attractive car but, like all the Lagonda 2-litres, it suffered from excessive weight.

In the meantime a version of the 3-litre known as the Lagonda Selector Special appeared. This Lagonda car was fitted with a Maybach gearbox that gave eight forward speeds, four high and four low, by means of an internal reduction gear with semi-automatic control. This Lagonda car was something of a failure, however, and was quietly dropped.

At the 1933 Motor Show two outstanding Lagonda cars were introduced: the 1.104cc Lagonda Rapier, with twin overhead camshafts and the 4½-litre Lagonda M45, having a similar Meadows 6-cylinder ohv engine to that in the now defunct Invicta. At last a Lagonda car had real performance and it is noteworthy that the Lagonda Car Company made their own very attractive coachwork.

For 1935 two additional Lagonda car models made their appearance, the 4½ Lagonda Rapide and the Lagonda 3½-litre, both using the same shortened chassis. It was no doubt this complexity of models which caused the Lagonda car company to get into financial difficulties, and a victory at Le Mans by a Lagonda Rapide came too late to save the day.

When in the summer of 1935 Alan Good saved the Lagonda Car Company from absorption by Rolls-Royce, he appointed W.O. Bentley as chief designer. The Lagonda LG45 model with which Bentley attacked the Luxury market in 1936 had longer road springs and Luvax dampers, but retained the Lagonda M45R engine and chassis. Not until the 1936 Motor Show could Bentley’s influence on the Meadows engine be seen in its definitive form in Lagonda cars. The Sanction III unit featured an improved coss-flow inlet manifold cast integrally into the head, onto which the carburetors were now bolted directly. Various other improvements on the engine of the Lagonda cars including a lightened flywheel allowed the line on the revolution counter to be moved up to 4.000rpm.

The last of the 4½-litre Lagonda cars was the Lagonda LG6 of 1938. This Lagonda car had independent front suspension, hydraulic brakes and outboard rear springs, but still used the Meadows engine. The V12 engine, brought out for the 1937 Lagonda car season, is considered the finest of W.O. Bentley’s designs. This 180bhp unit could raise the Lagonda car’s speed from 7 to 103,45mph on top gear without snatching; and this flexibility could be supplemented by revving freely to 5.000rpm on the indirects. Regrettably the Lagonda car design was never developed fully, for production was stopped in 1940, a few months after Lagonda Rapide versions had been placed third and fourth at Le Mans.

In 1947 the Lagonda car firm was taken over by the David Brown complex. Contrary to spelling the end of the traditional Lagonda car, the new merger enabled Bentley’s last motor-car design to be realized. This was the Lagonda 2.6-litre model which appeared in 1948. Its brilliant but unorthodox layout embraced a true cruciform chassis, independent rear suspension unique amongst British cars, and a twin ohc 6-cylinder engine. A bored-out edition of the 2.6 Lagonda car was offered as the 3-litre in 1951, featuring luxurious styling, rich appointments and a top speed of 110mph. HRH the Duke of Edingburgh had two Lagonda cars for his personal use, and for many years was a honorary member of the Lagonda Club.

The Lagonda Rapide was announced in 1961. Using a DB4 engine of 3.996cc capacity, the Lagonda car was set up on a platform chassis with independent springing all round, servo-assisted disc brakes and a De Dion rear axle. An elegant, aluminium Superleggera body by Touring of Milan contributed greatly to the Lagonda car’s massive acceleration. The Lagonda Rapide’s top speed was a genuine 125mph with comfortable cruising at 120; its sumptuous finish and appointments were in kepping with a price of £5.000. Production of Lagonda cars ceased in 1963, though a 4-door saloon version of the V8 Aston Martin DBS built for Sir David Brown in 1970 bore the Lagonda emblem.
