Chevrolet

US, 1911 to date

Chevrolet Motor Co, Detroit, Mich.

Chevrolet, General Motors’ least expensive American car and the world’s best-seller, was actually started by W.C. Durant at a time when he did not control GM. In association with racing driver Louis Chevrolet he brought out a 4.9-litre six with side valves in a T-head, selling for $2150. This was followed by a smaller 6-cylinder model, but the Chevrolet marque’s first big impact came with the 4-cylinder overhead-valve Chevrolet Baby Grand touring car at $875, and its companion roadster model, the Chevrolet Royal Mail. Electrics were an optional extra on Chevrolet cars for sale until 1917, but in the meantime the Chevrolet company had come right to the fore with the 2.7-litre 4-cylinder Chevrolet 490, also an ohv, in 1916. The type designation indicated its original list price in dollars, and sales went up from 13.600 to 70.701.
General Motors acquired Chevrolet in 1917, and by 1920 the Chevrolet marque was ousted in the United States only by Ford and Dodge. A one-model policy was pursued in 1923, but before this there had been other types of Chevrolet including the FA and FB fours, and a short-lived Chevrolet V8 with a Mason engine at $1100. There was also anabortive air-cooled Chevrolet car using the regular chassis and body styles in 1923. The 1925 Chevrolet Superior coach with disc wheels and Duco cellulose finish sold for $650, and two years later Chevrolet outsold Ford for the first time, though this was hardly a fair comparison, since Ford was shut down for a good part of the year during the change-over from the Model T to the Model A. Chevrolet did not have front-wheel brakes until 1928, the last year of the 4-cylinder cars. In 1929 came the ‘Cast Iron Wonder’, the 3.2-litre ohv Chevrolet International 6 with an 8ft 11in wheelbase and detachable disc wheels. More than a million Chevrolet cars were sold during its first season at $595, and the engine was progressively developed up to 1953.
In 1931 Chevrolet finally went ahead of Ford and stayed there apart from three seasons. 1932 Chevrolet cars resembled scaled-down Buicks or Oldsmobiles and featured rubber engine mountings, synchromesh and a free wheel, all for $495. In 1933 a V-grille was adopted to the Chevrolet cars, and capacity went up to 3.4-litres. GM’s Dubonnet-type ifs was fitted on the 1934 Chevrolet cars – in that year the ten millionth Chevrolet was delivered. Turret top styling followed in 1935 and hydraulic brakes in 1936. Engine capacity was increased slightly again in 1937. 1939 was the year of the fifteen millionth Chevrolet car; station wagons were catalogued, column-shift was optional, and prices ranged from $625 upwards. In 1940 Chevrolet was offering a power-top convertible in the low-price field, and Juan Manuel Fangio scored his first big victory in a long-distance race in Argentina at the wheel of one of that year’s coupés. Fastback Chevrolet coupés were listed in 1942, but along with most other American makes, the Chevrolet cars were little altered when they reappeared on the market after World War 2.

Extensive restyling and lowering took place in 1949, when a Chevrolet sedan cost $1460, but in 1950 Chevrolet offered the option of a 2-speed Powerglide fully-automatic transmission, as well as a now-fashionable hardtop coupé style. A new sports car, the Chevrolet Corvette, with fiberglass bodywork, featured in the 1953 programme with a 160bhp version of the regular 6-cylinder Chevrolet engine.
Chevrolet’s lead over Ford was down to a narrow 20.000 margin by 1954. In 1955 they came out with a 4.3-litre ohv V8 on conventional lines, giving 162bhp with an 180bhp ‘power pack’ available at extra cost. The capacity of the companion six was now 3.9-litres. By 1957 the Chevrolet Corvette had acquired the 8-cylinder engine, and special Chevrolet Corvette SS versions were being tried with 360bhp power units and 4-speed all-synchromesh boxes listed as a factory option. 1958 V8 Chevrolets had 5.7-litre engines and air suspension was available, though the idea was soon discarded.
A new departure was the Chevrolet Division’s 1960 compact car, the Chevrolet Corvair, a 2.3-litre air-cooled flat-6 with engine at the rear, unitry construction of chassis and body and all wheels independently sprung. It proved a little too advanced for the market at which it was aimed, but by 1966 Chevrolet had entered upon a new lease of life as a specialist semi-sporting machine available with such options as a 4-speed box and 180bhp turbosupercharged engine.

The evolution of subsequent Chevrolets reveals the need of the modern American mass-producer to offer a diversity of products, rather than to concentrate on a single basic model and ring the changes on body styles. In 1963 the Chevrolet company started to bridge the gap between the Chevrolet Corvair and the inexpensive, but by no means small Chevrolet Impala, Chevrolet Bel Air and Chevrolet Biscayne series(that year’s version were 17ft 6in long) with a ‘semi-compact’, thee Chevy II. This had integral construction, a 9ft 2in wheelbase and the choice of two engines of modest dimensions, a 2½-litre four and a 3.2-litre six. The slightly bigger Chevrolet Chevelle of 1964 was the first Chevrolet to use GM’s perimeter-type chassis frame (standardized on the big cars in 1965) and was available either with the Chevy II six or a 4.6-litre V8. Another new model in 1964 was the Chevrolet Corvette Stingray sports car with retractable headlamps, giving 145mph from 360bhp; the following season it had disc brakes as standard equipment. 1966 coverage of the market was comprehensive. Besides the specialized Chevrolet Corvair and Chevrolet Corvette there was the Chevy II in three series, the Chevrolet Chevelle with a wide choice of power units and five different types of full-sized Chevrolet from the inexpensive Chevrolet Biscayne up tot the luxurious Chevrolet Caprice. Prices ranged from $2028 for the simplest Chevy II with 90bhp 4-cylinder engine up to the Chevrolet Caprice custom station wagon at $3347. Chevrolet engines were used by Checker, Avanti, the revived 8/10 Cord, Excalibur, the last Canadian-built  Studebakers, the Anglo-American Gordon-Keeble and the Italo-American Iso and Bizzarini. They were also used in the smallest Oldsmobiles in 6-cylinder form and in Candian-built Pontiacs and the Acadian, an all-Canadian GM product. They are also found in the biggest 8-cylinder Opels. For 1967 the Chevrolet company added to its range a sports coupé model, the V8 5.7-litre Chevrolet Camaro with 295bhp and front disc brakes, a belated answer to Ford’s Mustang. 
Meanwhile Chevrolet Corvette-powered cars were dominating Can-Am racing, continuing to do so until 1971. Chevrolet’s sixth two-million year came in 1968 (the others had been 1962 – 1966 inclusive), the tenth successive season in which they had outsold Ford. Chevrolet Camaros were now available with 6½-litre engines, and the Chevrolet Corvette was completely restyled. Then 1969 brought the demise of the Chevrolet Corvair, the final season’s sales being a low 2359 as against its 1961 peak of 316.000. A further gap in the range was filled by the Chevrolet Blazer, a 4x4 jeep-type vehicle offered with 6-cylinder or V8 engine. Sporting and prestige images were combined in the Monte Carlo of 1970, a coupé on the Chevrolet Chevelle chassis with front disc brakes and a choice of five V8 units, the biggest having 7.3-litres and 360bhp. This was the last year of 4-cylinder engines in the Chevy II line, and Chevrolet Camaro sales came within 20.000 of the Ford Mustang’s. The major news of 1971 was a sub-compact, the unitary-construction Chevrolet Vega with coil rear suspension, offered in hatchback coupé, 2-door sedan and station wagon styles, and powered by a new 2.3-litre 4-cylinder engine with alloy block and cogged belt drive for its overhead camshaft. Transmission options included a 3-speed semi-automatic and front disc brakes were standard. The 1973 line was one of the biggest in the USA, embracing the Vega, Chevy II Nova and Chevelle in the compact and intermediate markets, the Chevrolet Bel Air, Chevrolet Impala and Chevrolet Caprice with 10ft 1½in wheelbase in the full-size group; the Chevrolet Camaro and Chevrolet Monte Carlo coupés; the Chevrolet Corvette sports car; and such specialist semi-utility types as the Chevrolet Blazer, the Chevrolet Suburban station wagon on a light-truck chassis, the forward-control twelve-seater Chevrolet Sportsvan station wagon, and the Chevrolet El Camino, a car-based coupé-utility in the Australian idiom. All passenger-car types with the exception of the Chevrolet Nova had front disc brakes as standard equipment, while innovations were a Nova hartchback coupé and a restyled and lowered Monte Carlo available with V8s of 5736cc or 7440cc. Power-assisted steering was standard on Camaros, big Chevrolets were now offered only with automatic transmissions, and energy-absorbing front bumpers were found on all types.
In the summer of 1972 Chevrolet announced plans for a Wankel-powered Vega to be available by 1975.

Sunbeam

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.
