The American Benjamin Berkeley Hotchkiss set up his ordnance Horchkiss car factory at St. Denis in 1867; the Hotchkiss cars were the result of an arm slump. The work of Terrasse, these first Hotchkiss cars were T-headed fours with pair-cast cylinders, 5-ball-bearing crankshafts, low-tension magneto ignition, round honeycomb radiators, 4-speed gearboxes, and the famous Hotchkiss drive by live axle and open propeller shaft. Initially cylinder capacities of Hotchkiss cars were 4.6-litres and 7.4-litres, but the Hotchkiss car company’s first racers of 1904 were 17.8-litre monsters notable for their aiv and chain drive. Though their 1905 successors conformed once more to touring-car practice, they were even bigger Hotchkiss cars, with 18.815cc and an alleged 130bhp. Hotchkiss’s last racing season was 1906 with their Grand Prix Hotchkiss cars had 16.3-litre L-head units and quick-detachable wire wheels. Though these Hotchkiss cars were unsuccessful, Hotchkiss sold 167 cars that year, with gate change standardized, and a choice of five Hotchkiss car models: a short-lived 4.2-litre petrol brougham, fours of 18, 30 and 42hp, and their first six. The last-mentioned Hotckiss car was the large V-type that evolved into a 9½-litre machine and was still being offered in 1912 as a Hotckiss car. Chassis price was £1.000 and it was capable of 60mph.

The slump following the Agadir crisis led to the abandonment of ball-bearing crankshafts on Hotchkiss cars; at the same time there was a move towards smaller Hotchkiss cars with the 3.1-litre T-type, with side valves in an L-head and high-tension magneto ignition. Two years later came something even smaller and more modern, the 12/16hp Hotchkiss X-type with 2-bearing crankshaft and three forward speeds at £390. Soon monobloc engines spread up the range to the 3.7-litre Hotckiss AB of 1912. From 1911 there were some smaller L-head sixes, the 4.678cc Hotchkiss X6 and the 5½-litre Hotchkiss AC6; 1912 sales were a record 598 Hotchkiss cars. Electric lighting was available from 1913, and all the 1914 Hotchkiss car models – the 2.6-litre Hotchkiss AG, the 4-litre Hotchkiss AF, the 5.7-litre Hotchkiss AC, and the 6-cylinder Hotchkiss AC6 – had semi-elliptic suspension all round.

The wartime demand for Hotchkiss machine guns led to the establishment of a branch factory under the Englishman Harry Ainsworth, this subsequently making engines for W.R. Morris until it was absorbed by him in 1923. At home Hotchkiss sold off their surplus works capacity at Lyons and concentrated on a revised Hotchkiss car again, the AF with full electrics and a horseshoe-shaped radiator in place of the traditional round one. Its successor, the Hotchkiss AH of 1921, had cantilever rear springs and torque tube drive, and a year later came the Hotchkiss AL with ohv, and a detachable head; front-wheel brakes were added for 1923. There was also a prototype luxury Hotchkiss car at the 1921 Paris Salon; this Hotchkiss AK had a 6.6-litre 6-cylinder ohc engine, dual ignition, 4-speed unit gearbox, servo-assisted 4-wheel brakes, and a cruciform-braced frame, but it never went into production.

The return of Ainsworth to St. Denis in 1923, coincided with the construction of a new Hotchkiss car factory and a more realistic type of car, the 2.4-litre 12CV Hotchkiss AM, with 4-cylinder sv engine, 4-speed unit box, four-wheel brakes, wire hwwls, and Hotchkiss drive once more. Between 1924 and 1928 it was the Hotchkiss car company’s staple product, selling at the rate of over a thousand a year and offering a 70mph performance at a modest outlay. It persisted until 1932, acquiring ohv in 1926 and rod-operated brakes in 1928, and its engine was used in some Morris-Léon Bollées. Even better was the Hotchkiss AM80 of 1929, largely the work of Bertarione. This was a short-stroke (80x100mm), 7-bearing ohv 3-litre six that owed a good deal to the AM2, though early cars featured torque tube drive; it was to be the basis from which all subsequent Hotchkisses were evolved. A silent 3rd gearbox featured on 1931 Hotchkiss car models, Hotchkiss drive reappeared in 1932, and 1933 improvements included Bendix brakes, cruciform-braked frames, down-draught carburetors and mechanical fuel pumps. Hotchkiss AM80 engines were also fitted to Sizaire Frères and Tracta cars.

The 1933 Hotchkiss car range was expanded both up and down, with new Hotchkiss 12CV (2-litre) and 13CV (1.3-litre) fours for the economy market, and an 85mph fast tourer, the 100bhp 3½-litre Hotckiss AM80S, for the enthusiast. This Hotchkiss car was based on the car with which Vasselle won the 1932 Monte Carlo Rally. Hotchkiss cars repeated this success in 1933 and 1934: in the latter year the Hotchkiss cars collected two Glazier Cups in the Alpine Trial. There were further wins in the Monte Carlo in 1938 and 1939; on the latter occasion a Grand Sport Hotchkiss car tied with a 3½-litre Delahaye. Radiators were moved forward on the 1934 Hotchkiss cars, and the 3-litre gave way to a 2.650cc 15CV that was not a success and lasted only one season. The 1935 Hotchkiss cars had synchromesh and integral boots, and at the top of the 3½-litre 20CV range was the twin-carburettor Hotckiss Paris-Nice, a 115bhp sports car capable of 95mph. Hydraulic brakes appeared in 1936 on Hotchkiss cars (to be quietly dropped halfway through 1937). The sports 20CV engine was now giving 125-130bhp and when allied to a short 9ft 2in wheelbase resulted in the Hotchkiss Grand Sport, a true 100mph saloon.

By 1938 the horseshoe radiator on the Hotchkiss car was now a wire-mesh grille, but despite the exigencies of French rearmament programmes the Hotchkiss car company managed to deliver 2.751 Hotchkiss cars that year, made up of the two fours, the reinstated 3-litre Hotchkiss 680, and the 3½-litre Hotchkiss 686 in various forms, including seven-seater limousines with the single-carburettor 100bhp engine. Hotchkiss also came to the rescue of the ailing Amilcar concern, helping to make the Grégoire-inspired 1.185cc Compound, a small fwd saloon with unitary construction in Alpax; this was sold in England, though not in France, as a Hotchkiss car. A 1.3-litre ohv development, the Hotchkiss B67, was ready for production when France collapsed in the summer of 1940.

Hotchkiss never really recovered from World War 2, though Peugeot were briefly interested in the Hotchkiss car company and Hotchkiss 686 cars won the first two post-war Monte Carlo Rallies of 1949 and 1950. The Hotchkiss 12CV and Hotchkiss 20CV were back in production, unchanged, by 1946, but the first year’s output was a miserable 117 Hotchkiss cars. Hydraulic brakes and independent front suspension did not appear until 1949 on Hotchkiss cars (though Hotchkiss had experimented with the latter in 1937), and a Cotal electric gearbox became a factory option. The 1951 Hotchkiss car models were ‘facelifted’ with V-screens, recessed headlamps and auxiliary coil rear suspension, but in the meantime there had been an expensive mistake: the acquisition by Hotchkiss of the rights to the Grégoire flat-4. This ingenious device was a development of the 1938 Amilcar theme featuring all-round independent suspension and a 4-speed overdrive gearbox, as well as front wheel drive. Production Hotchkiss car models with 2.2-litre engines were said to achieve 95mph and 30mpg, but the teething troubles were endless, and Hotchkiss only managed to make 250 Hotchkiss cars in the end. There was a shutdown in 1952 and the price of recovery was a merger with Delahaye that led inevitably to concentration on commercial vehicles. The old Hotchkiss cars 13CV and 20CV received another facelift in time for the 1954 Paris Salon, but his was their swansong, though medium-powered trucks continued to be made until 1970, along with a version of the American Jeep built under licence.

GB, 1920

Hotchkiss et Cie, Coventry, Warwickshire

Hotchkiss of Coventry, a British offshoot of the famous French Hotchkiss car firm, was set up during World War 1 to make engines in Britain. Their units became best known as the motive power for Morris and BSA light cars, but before they were taken over by William Morris, Hotchkiss experimented with a small car of their own. The Hotchkiss car consisted of their 1.080cc air-cooled V-twin ohv engine installed with a 3-speed gearbox in a pre-war Morris Oxford chassis. It never went into production.

Rolls-Royce

GB, 1904  to date

(1) Royce Ltd, Manchester, 1904 – 1906

(2) Rolls-Royce Ltd, Manchester, 1906 – 1908

(3) Rolls-Royce Ltd, Derby, 1908 – 1945

(4) Rolls-Royce Ltd, Crewe, Cheshire, 1946 – 1971

(5) Rolls-Royce Motors (1971) Ltd, Crewe, Cheshire, 1971 to date

The Rolls-Royce car was the result of a meeting between Henry Royce, a manufacturer of electric cranes in Manchester, and the Hon. C.S. Rolls, a pioneer motorist then selling Panhards in London, who wanted a quality car to boost falling sales. The first Rolls-Royce cars were based on the 1.8-litre (later enlarged to 2-litre) vertical-twin 10hp ioe Royce with shaft drive, but the range of Rolls-Royce cars was expanded to embrace a 3-litre, 3-cylinder, ‘light’ and ‘heavy’ versions of a 4-cylinder Rolls-Royce Twenty, and a 6-litre pair-cast six retailing at £900. A Light Twenty Rolls-Royce car with geared-up top, driven by Rolls, won the 1906 Tourist Trophy, and also broke the Monte Carlo-London record.

An abortive 3½-litre V8 petrol brougham Rolls-Royce car with square cylinder dimensions was shown in 1905, but 1906 was the start of a one-model policy based on the 40/50hp 6-cylinder Rolls-Royce car, later to win immortality as the Rolls-Royce Silver Ghost, which Rolls-Royce car made its début at Olympia that year. This Rolls-Royce car had a conventional 7-litre sv engine with pressure lubrication and dual ignition, as well as the 4-speed overdrive gearbox. Output of the Rolls-Royce Silver Ghost was a modest 48bhp, but the Rolls-Royce car’s reputation was assured after a successful 15.000 mile RAC-observed trial in 1907, from which the Rolls-Royce Silver Ghost emerged with flying colours. 6.173 Rolls-Royce Silver Ghost cars were made: the first ones at Manchester, and from 1908 on the Rolls-Royce cars were made at Derby. At £985 for a chassis the Rolls-Royce car was backed by a unique inspecition scheme, and in mid-1909 it was revised with a longer-stroke 7.4-litre engine and conventional 3-speed box. The Rolls-Royce Silver Ghosts reverted to 4 speeds in 1913, when cantilever rear suspension was adopted; later modifications were full electrics (1919) and Hispano-Suiza-type mechanical servo 4-wheel brakes (1924). The ‘Best Car in the World’ – a reputation which was well established by Rolls-Royce cars by 1914 – was not normally entered in competitions but in 1911 a Rolls-Royce Silver Ghost was successfully driven from London to Edingburgh and back on top gear for a fuel consumption of 24.32mpg, and a works team Rolls-Royce car swept the board in the 1913 Austrian Alpine Trials. Armoured-car versions of the Rolls-Royce Silver Ghost gave yeoman service both during and after World War 1.

Production of Rolls-Royce cars was resumed after the Amistice, the chassis price being inflated to £2.100. In 1920 an American Rolls-Royce car actory was opened, this making the Rolls-Royce car until 1931. Post-war 1 inflation led Rolls-Royce to abandon their one-model Rolls-Royce car policy in 1922 and to introduce a 3.1-litre ohv 6-cylinder Rolls-Royce Twenty with a 3-speed unit gearbox and central change at £1.100 for a chassis. This Rolls-Royce car was regarded by Rolls-Royce enthusiasts as heresy, but the Rolls-Royce Twenty was an excellent if sluggish car which last none of the traditional quality; nearly 3.000 Rolls-Royce cars were made up to 1929. In 1925 the Rolls-Royce car acquired a 4-speed box, right-hand change, and the servo 4-wheel brakes of the Rolls-Royce Silver Ghost, which was retired that year in favour of a 7.7-litre Rolls-Royce Phantom I with overhead valves and vertical radiator shutters. An improved Phantom II Rolls-Royce car with hypoid back axle and redesigned combustion chambers was listed from 1930, while the Rolls-Royce Twenty emerged as the more powerful Rolls-Royce 20/25 with a 3.7-litre engine. A Continental version of the bigger Rolls-Royce car gave a genuine 90mph with closed coachwork. Refinements of the early 1930s on Rolls-Royce cars included synchromesh (on the 20/25 in 1932, and on the Phantom a year later), and centralized chassis lubrication (1933).

In 1931 the Rolls-Royce car company bought Bentley Motors, after Napier had made an unsuccessful bid. The Bentley emerged two years later, as a Rolls-Royce-based 3½-litre: it was not to lose its identity until the 1950s. Sir Henry Royce died in 1933, and the entwined ‘R’s of the radiator emblem of the Rolls-Royce car was changed from red to black, supposedly in mourning. The smaller Rolls-Royce cars acquired hypoid final drive in 1936, in which year an alternative power unit of 4¼-litres’ capacity was offered, first as an option on the Rolls-Royce car, and then as standard: thus the 20/25 Rolls-Royce car grew up into the 25/30. In this year Rolls-Royce cars stopped making their own carburetors, though electrical equipment was not bought out until after World War 2. Aero-engine influence (the Rolls-Royce car company had been making these units since 1914 and had been responsible both for the Schneider Trophy R engine of 1931 and the Merlin of 1935) was reflected in the 12-cylinder Phantom III Rolls-Royce car first shown in 1935. The capacity of this Rolls-Royce car was 7.3-litres, and it was the first Rolls-Royce car to have independent front suspension. Later examples Rolls-Royce cars had overdrive gearboxes. It offered 90-95mph for £2.600 and up. This Rolls-Royce car model was still being made in 1939, along with a development of the 25/30, with independent front suspension, the Rolls-Royce Wraith, which Rolls-Royce car could be bought for around £1.600 complete.

Post-war 2 production Rolls-Royce cars was transferred from Derby to Crewe and the first new Rolls-Royce car model was the Rolls-Royce Silver Wraith, with a 4¼-litre engine, overhead inlet valves and hydraulic actuation for the front brakes, this Rolls-Royce car costing around £4.300 in 1947. The Rolls-Royce Phantom III was not revived, but sixteen ioe 5.7-litre straight-8 Phantom IV Rolls-Royce cars were made for heads of state from 1949 onwards. Among the customers of the Rolls-Royce car was HRH Pincess Elizabeth, who was to become the first reigning British monarch to use Rolls-Royce cars officially. The 6-cylinder Rolls-Royce cars continued up to 1959. 1949 brought the first Rolls-Royce car factory-bodied model, the export only Rolls-Royce Silver Dawn, using the standard Bentley saloon body, left-hand drive, and steering column change. In 1952 capacity of the Rolls-Royce car went up to 4.6-litres and a long-chassis version was listed with an 11ft 1in wheelbase. The General Motors Hydramatic transmission became an option in 1953, and the famous manual box with right-hand control was finally dropped two years later with the advent of a 4.9-litre Rolls-Royce Silver Cloud, a restyled saloon with 15in wheels, which Rolls-Royce car could be bought with power-assisted steering and full air-conditioning. 1960 Rolls-Royce cars were identical in outward appearance, but were powered by entirely new oversquare alloy 6.2-litre V8 engines. Power assisted steering was now standard on the Rolls-Royce car, though the hydro-mechanical servo brakes were retained. The standard saloon Rolls-Royce car cost £6.093, and a limousine version on a 12ft wheelbase, the Rolls-Royce Phantom V, was some £3.000 dearer. A four-headlamp layout was introduced on the Rolls-Royce car in 1963, and a year later Rolls-Royce cars started to supply a 4-litre version of their ioe 6-cylinder engine to BMC for installation in the Vanden Plas Princess.

At the 1965 Shows Rolls-Royce cars introduced an entirely up-to-date design, the Rolls-Royce Silver Shadow. This Rolls-Royce car boasted unitary construction, self-levelling, all-round independent suspension, and servo-assisted disc-brakes with three separate circuits. It retained the 1960 V8 engine, also the (now dummy) traditional radiator. The Phantom V Rolls-Royce car with its separate chassis was kept on, a ceremonial limousine for head of state being listed at £10.695. A Silver Shadow convertible was available in 1968 for £10.449; 1969 brought both a long-wheelbase version of the Rolls-Royce car model and the enlargement of the engine to 6.745cc. In 1970 a new 3-speed automatic gearbox (already used on left hand drive export models since late 1965) replaced the earlier 4-speed type on the Rolls-Royce car, and the Phantom VI replaced the Phantom V; production of these state Rolls-Royce carriages ran at about 50 Rolls-Royce cars a year. Similar modifications were applied to the parallel Bentley cars. The sensational bankruptcy of February 1971 found the Rolls-Royce Car Division still profitable; indeed, within a month the Rolls-Royce car company had announced their high-performance Rolls-Royce Corniche 2-door saloon and convertible with coachwork by H.J. Mulliner-Park Ward, at prices from £12.829 upward, and that December the 10.000th Silver Shadow Rolls-Royce car left Crewe. By late 1972 prices of the more expensive Rolls-Royce cars had risen to £14.399 for the Rolls-Royce Corniche and £15.559 for the Rolls-Royce Phantom Limousine.

US, 1921 – 1931

Rolls-Royce of America Inc, Springfield, Mass.

The American Rolls-Royce car company was formed in November 1919 to build the famous British Rolls-Royce cars in an American factory and so avoid high import duties. The Rolls-Royce car plant was bought from the American Wire Wheel Co, and the Rolls-Royce Silver Ghost went into production there in 1921. This Rolls-Royce car had a 6-cylinder 7.4-litre sv engine developing 80bhp, and came in two wheelbases, 12ft and 12ft 6½in. Right-hand drive was used until 1923. Unlike the British Rolls-Royce car company, Rolls-Royce of America always advertised coachwork and supplied complete Rolls-Royce  cars if customers wished. Most bodies of the American Rolls-Royce cars were by Brewster, and in 1926 this firm was taken over by Rolls-Royce car company. In 1926 came the New Phantom, or Rolls-Royce Phantom I as it was later called. This Rolls-Royce car had a 6-cylinder 7.7-litre engine with overhead valves, and again came in two wheelbases, 11ft 11½in and 12ft 2½in. The Depression badly hit sales of the American Rolls-Royce car, and production of Rolls-Royce cars at Springfield came to an end in 1931, although a few British Rolls-Royce cars were assembled there later. A total of 2.944 American Rolls-Royce cars was made, of which 1.703 were Rolls-Royce Silver Ghosts and 1.241 were Rolls-Royce Phantom Is.
