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.

Alvis

GB, 1920 -1967

(1) T.G. John Ltd, Coventry, Warwickshire, 1919 – 1937

(2) Alvis Car & Engineering Co Ltd, Coventry, Warwickshire, 1921 – 1937

(3) Alvis Ltd, Coventry, Warwickshire, 1937 – 1967

From its beginning, the name of Alvis has connoted high quality, long life and better-than-average performance. The first production Alvis set the trend. Those responsible for it were T.G. John, formerly of Siddeley-Deasy, and G.P.H. de Freville, who had worked for D.F.P. and had designed aluminium pistons bearing the name of Alvis for them. Their 10/30hp light car, current until 1922, used an extremely efficient 4-cylinder sv engine of 1.460cc made by Alvis, a 4-speed gearbox and attractive aluminium bodies by Morgan or Charlesworth. It was available in two-seater, four-seater or Super Sports form. The last-named as the first Alvis to have the famous ‘duck’s back’ body. Though noisy and expensive, the aLVIS ‘10/30’ was immensely popular among sporting motorists. In 1921, 322 examples were sold and by the following year the Alvis company employed 350 people. At the end of 1919, the new-born company had undertaken to deliver 1.000 cars, but the moulders’ strike which a brief spell during this period, the company made the Buckingham cyclecar.

In 1922, an engine of 1.598cc with a bigger bore and rated at 12/40hp was introduced in Alvis cars designed more for touring. Captain G.T. Smith-Clarke became chief engineer in 1923. He was responsible for the push-rod ohv 12/50hp engine, which was quieter and more powerful than its predecessors and at the same time extremely strong and long-lasting. It was first seen, in modified form, in the Alvis that won the Brooklands 200-Mile Race of 1923. The touring Alvis models were provided with 1.598cc engines, but the Alvis Super Sports had a shorter stroke giving 1.496cc and was more highly-tuned. The former were usually capable of about 60-65mph, but the latter would exceed 70mph comfortably. Handling qualities of all Alvis models were excellent, while bodies were by Cross & Ellis. During 1924 all Alvis cars went over to the new engine. At first, the Alvis firm’s survival was doubtful. Although 963 units of the older Alvis models had been sold in 1923, a receiver had to be appointed in the following year, because of lack of the capital needed for production on a scale to meet demand. More money was forthcoming, however, and the new Alvis 12/50hp restored the company’s fortunes. Prices were reduced for 1926, and all Alvis models were given front-wheel brakes. The chassis was stiffened by doing away with the separate subframe that had carried the engine and gearbox, and the engine was rubber-mounted. The downward-sloping ‘beetle-back’ tail was now the Super Sports style. By 1928, 6000 Alvises were on the road, and production was running at about 900 chassis per annum.

In that year, Alvis introduced a new type that was also to be a great success. Following fashion, it was a small six of 1.870cc. Similar in design to the old four, this Alvis was smoother, more flexible and quieter. Bodies were roomier and gearing was lower. This Alvis 14.75hp was superseded by the Alvis Silver Eagle in 1929, a car with a bigger bore that gave a mistake. They put into production a Alvis sports machine that had front-wheel-drive (Alvis FWD) – the first instance of this type of drive in a catalogued car – and independent suspension by four quarter-elliptic springs at the front and swing axles with quarter-elliptics at the rear. The 4-cylinder, 1.482cc, single ohc engine utilized many Alvis 12/50 parts, and could be had with a Roots-type supercharger. Helped by a low centre of gravity, the roadholding was very fine, and so were the brakes. During 1928 this Alvis model finished 6th and 9th at Le Mans, and 2nd in the Ulster Tourist Trophy race. In the following year an 8-cylinder version, still of 1½-litres was added. Unfortunately, the Alvis fwd had a very specialized, limited appeal, being complicated, unconventional, temperamental and hard to work on. However, Alvis were so confident in them and in the new six that they announced suspension of the production of the Alvis 12/50 in 1929. It was hurriedly reinstated when the six, popular though it was, proved insufficient to keep the Alvis company going alone. It was for sale until 1932, alongside a new sporting variant, the Alvis 12/60hp.

This was the Alvis company’s last out and out sports car, but its reputation for high-performance vehicles was sustained by the introduction of another new line for sale in 1932. The Alvis Speed Twenty was an exceptionally low-built, handsome fast tourer of modern appearance that combined the refinement of a medium-sized (2.511cc) six with speed, excellent roadholding and brakes, stamina and a reasonable sales-price. The car, and the types which succeeded it were a great success. The engine was a slightly tuned version of the largest option available in the Alvis Silver Eagle, and the chassis, too, was basically similar to that of the earlier Alvis model, which was retained. The power output was about 87bhp, permitting the better examples of the Vanden Plas open tourer to attain 90mph, in spite of the car’s weight, which was an equally traditional Alvis feature. The bodies were all coachbuilt.

With the introduction of this Alvis, the character of Alvis policy in the 1930s was set: the Alvis Speed Twenty and its developments provided the glamour, while an assortment of ‘bread-and-butter’ fours and sixes backed it up. All had push-rod ohv engines. The old Alvis ‘12/50’ and Alvis ‘12/60’ were replaced for 1933 by the sale of the heavier Alvis Firefly in the 1½-litre, 4-cylinder range. Much of the extra weight was added by the optional Wilson pre-selector gearbox, which could also be had on its development, the Alvis Firebird of 1935. This car, however, had an 1.842cc engine, in an attempt to cope with the avoirdupois. The Alvis Silver Eagle was joined early in 1933 by the 2.511cc Alvis Crested Eagle, which also had a Wilson gearbox. This was a chassis intended to carry heavier boddies, and was important because it was the first Alvis touring car to have independent front suspension, which was by a single transverse leaf. This feature, together with an all-synchromesh gearbox, was seen on the 1934 Alvis Speed Twenty. The latter model for sale, which was also growing heavier with increasing public demand for comfort rather than sporting pretensions, was given a bigger engine of 2.762cc in 1935 by lengthening the stroke.

For the same reason, the Alvis 3½-litre also made its bow. It was basically similar to the Alvis Speed Twenty, which it supplemented, but had a smoother, quieter engine with a bigger bore, providing 3.571cc and was designed to accommodate more comfortable, less sporting bodies. The Alvis 3½-litre was, however, a more powerful car than the Alvis Speed Twenty, with 110bhp. It was a short and logical step to replace the Alvis Speed Twenty with a new car for sale for 1936 that combined the virtues of both models. This was the fine Alvis Speed Twenty-five, which used the 3.571cc engine. Capable of a smooth and silent 95mph in saloon form, it was what many people still regard as the best Alvis ever built. At the same time, a car that was originally envisaged as a replacement for the short-lived Alvis 3½-litre was announced. This Alvis 4.3-litre had the same engine, bored out to a capacity of 4.387cc and providing 123bhp. With the introduction of the short-chassis sports tourer version for 1938, the Alvis 4.3-litre became the most exciting Alvis in the range, for it could easily exceed 100mph, with acceleration to match. Some consider that it was not quite as good-looking as the Alvis Speed Twenty-five, nor equally refined.

A new four for sale to replace the Alvis Firebird was listed for 1938. This was the Alvis 12/70hp, a George Lanchester design, with an 80mph performance in spite of its weight. The engine size was unaltered. The Alvis Silver Eagle had been dropped in 1936, but the Alvis Crested Eagle became for sale in a number of versions with the 2.762cc and 3.571cc engines as they appeared, in less highly-tuned forms. The Alvis Silver Crest, another Alvis car in which George Lanchester had a hand, was also brought in for sale in 1938 alongside the 12/70hp. It was intented to carry bodies of the more formal sort, and was powered by the 2.762cc engine, among others. It, too, had independent front suspension.

An aero engine works had been opened as early as 1937. The Alvis car factory at Holyhead Road, Coventry was completely destroyed by bombing in 1940, but the company continued to make aero engines – Rolls-Royce Merlins – at eighteen shadow factories. After World War 2, Alvis made their own Leonides unit and Alvis car production was restarted in 1946. A one-model policy, tailored to meet conditions of austerity, was adopted. Quality was still the main characteristic of the new Alvis TA14 for sale, which, in Alvis tradition, used a 4-cylinder push-rod ohv engine, now of 1.892cc.This Alvis TA14 car was the direct descendant of the 12/70hp. An ugly sporting model appeared briefly for sale in 1948. The Alvis TA14 was dropped during 1950 and the Alvis TA21, a big six, substituted. This was the first entirely new post-war Alvis. Its 2.993cc engine developed 90bhp, and this Alvis car – though not its sports roadster variant the Alvis TB21 – was as slower car than the Alvis Speed Twenty-five. Not so its development, the Alvis TC21/100, for sale in 1954 and 1955. This, after attention from Alec Issigonis, had a tuned engine providing 100bhp and a higher axle ratio, and carried a 100mph guarantee. The Alvis TC21/100 did not last long, for in 1955 there appeared one of the handsomest cars Alvis ever made, the Graber-designed Alvis saloon on what was virtually the Alvis TC21/100 chassis. Few were built until 1959, when this car was given a modified engine delivering 120bhp and renamed the Alvis TD21. It acquired disc brakes as standard fittings on all four wheels for 1962. For 1964, it was replaced by Alvis TE21, with 130bhp and five forward speeds. Automatic transmission was optional. In 1965 Rover acquired a controlling interest in the firm; production of private ceased in the summer of 1967.
