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.

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.

Morgan

GB, 1905 – 1906

Morgan and Co Ltd, Leighton Buzzard, Beds.

Made by a well-known firm of coachbuilders, the Morgan car was a conventional shaft-driven car with 5.8-litre T-head 4-cylinder Mutel engine, distinguished only by the Sparks-Boothby hydraulic clutch on the Morgan car, soon abandoned in favour of an ordinary leather cone. Only about five Morgan cars were made and their lack of success resulted in Morgan cars becoming Adler concessionaires in 1907, and abandoning motor manufacture.

GB, 1910 to date

Morgan Motor Co Ltd, Malvern Link, Worcs.

This Morgan car was the best-known, and best, of the British 3-wheelers that were popular while the horsepower tax gave the Morgan cars an advantage. H.F.S. Morgan’s tricycle was also the first of its type, this Morgan car going into production in 1910. At the front of a tubular chassis frame was an sv, air-cooled V-twin motor-cycle engine of 1.100cc by JAP, transversely mounted. Transmission of the Morgan car was by dog clutches and chains, providing two forward speeds. The steering was direct. The front wheels of the Morgan car, had independent front suspension, by sliding pillars and coil springs. There were two seats. A reasonable amount of power plus light weight meant an excellent performance of the Morgan cars. The Morgan car was safer than most 3-wheelers because its road-holding was above average. This recipe made the Morgan car popular with sportsmen, for whom the Morgan Grand Prix model was produced in 1914: the first catalogued competition Morgan car. Soon afterwards, an exiguous four-seater Morgan car, the forerunner of the Morgan Family model of the 1920s, was listed.

After World War 1, Morgan carscontinued to cater for all markets. Names changed, but the Morgan Sports or Morgan Standard model was the normal two-seater, also available in De Luxe form; the Morgan Family model was the more capacious type Morgan car, and the long-tailed Morgan Aero, later the Morgan Super Sports, was the Morgan car intended for serious speed work. Engines of Morgan cars were water- or air-cooled to choice, most being supplied by JAP, or by Blackburne in the case of the competition Morgan cars. From 1925 all the latter’s power units had overhead valves. By 1927 the Super Sports Morgan car could attain 80mph in standard trim, while the less sporting Morgan cars now had internal expanding front wheel brakes and electric starting. Geared-down steering and (if required) three forward speeds followed on Morgan cars in 1929. Even so, Morgan cars were losing customers to new, cheap sports cars such as the M-type MG. Three speeds and reverse in a normal gearbox (though still with chain final drive) were available from 1931 and standard on the Morgan car after 1932, and a modified 8hp Ford 4-cylinder engine could later be had in the Morgan car instead of the twin. Four years later the first 4-wheeled Morgan car was introduced, the excellent little Morgan 4/4. This Morgan car used an 1.122cc 4-cylinder Coventry-Climax engine with overhead inlet valves, developing 34bhp. The Morgan car was still light in weight, and retained the Morgan independent front suspension, so the performance and handling qualities of Morgan cars were well up to form. The Morgan car could attain 75mph. The twins were last catalogued in 1939.

Just before World War 2, a 1.267cc Standard 10hp engine with ohv head was substituted in the Morgan 4/4. When this was no longer available, from 1950, Morgan fitted a tuned Standard Vanguard unit in the Morgan car giving 70bhp. In this Morgan Plus Four, as the Morgan car was renamed, performance became still more lively, and when the 90bhp Triumph TR2 engine became available in 1954, maximum speed of the Morgan car rose to 100mph for the first time. With the advent of the Morgan Plus Four, there was no longer a small Morgan car, but this gap was made good in 1955, when the Morgan Series 2 4/4 arrived. This Morgan car used the very hard-wearing 1.172cc sv Ford Ten engine which had powered F4 Morgan. (The latter was the last 3-wheeler Morgan car, which had been made until 1950.) The result was a cheap, pleasant and reliable sports Morgan car of the old school. Later, the ohv Ford 105E engine was substituted. The latest version Morgan car had a 1.599cc 98bhp engine, a 4-speed all-synchromesh gearbox, front disc brakes, and the traditional Morgan suspension. The Morgan Plus Four kept pace with Triumph’s TR engine development, also acquiring disc brakes and, eventually, the 2.138cc 105bhp TR4 unit. A streamlined coupé, the Morgan Plus Four Plus of 1964, was a brief deviation from the classical Morgan car line which met with little approval and was discontinued after only 50 of these Morgan cars had been sold. When Triumph changed to a six during 1968, Morgan cars adopted a new engine for their bigger Morgan cars, and the Morgan Plus Four became the Morgan Plus Eight, powered by Rover’s 3 ½-litre 160bhp V8 and capable of 125mph. The 1973 versions of the Morgan car use the 4-speed all-synchromesh Rover gearbox in place of the Moss box previously fitted.
