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.

Mercury

US, 1904

Mercury Machine Co, Pittsburgh, Pa.

The Mercury car was a two-seater with a 2-cylinder water-cooled engine of 7hp. A liding-gear transmission was used and the weight of the Mercury car was 1.250lb. The price of the Mercury car was $295 and a top cost $100 extra.

GB, 1905

Ivanhoe Motor Co, Cricklewood, London N.W.

The Mercury car company made a small number of 24hp 4-cylinder Mercury cars which they also called Ivanhoes. In 1906 they became agents for Weigel and planned to show these cars on their stand at Olympia, but permission was refused because they had said in their application that they would show Ivanhoes. In fact, only second-hand Mercury cars were shown on the stand, but they stressed that the Weigel could be seen at the works.

(2) Mercury Cars (production) Ltd., Twickenham, Middlesex, 1920 – 1923

The Mercury car was a conventional light car with a 10hp 4-cylinder monobloc engine and shaft drive. One Mercury car model only was made before the war, but in 1920 there were three Mercury cars, a 9.5, 10.2 and 11.9hp. Bodies were the usual two- and four-seaters.

US, 1914

Mercury Cyclecar Co, Detroit, Mich.

The Mercury cyclecar differed little from other of that breed, except that Mercury car had a self-supporting body which eliminated the chassis frame; in other words integral construction. The engine was a 9hp 2-cylinder air-cooled unit, and the Mercury car used friction transmission and belt final drive. Body styles were a monocarp, a tandem two-seater and a light van.

US, 1918 – 1920

Mercury Cars Inc, Hollis, N.Y.

A small, assembled car of limited production, the Mercury car used a Duesenberg or Weidely 4-cylinder engine and the Mercury car was equipped with a door in the floor to give the driver ready access to the service brake mechanism.

US, 1938 to date

Ford Motor Co, Detroit, Mich.

The Mercury car, a product of Ford’s Lincoln Division, was intended to rival GM’s Oldsmobile and Buick, and widen Ford penetration of the American market. The Mercury car was in effect an enlarged Model 91 Ford V8 with a 3.9-litre 95bhp engine. At $957 the Mercury car cost $230 more than its smaller sister, but the Mercury car was $40 less than Buick’s cheapest 4-door sedan. Hydraulic brakes were standard from the start on Mercury cars and evolution followed established Ford lines, with no drastic changes until 1949, when the new low silhouette, hypoid rear axle, and coil-spring independent front suspension were incorporated on the Mercury car. Capacity of the engine of the Mercury car went up to 4.2-litres and the front-end styling of the Mercury car emphasized the association with Lincoln. Mercury cars, like Ford, progressed to overhead valves and oversquare cylinder dimensions and in 1955 buyers of the Mercury car had a choice of two V8 engines of 188 and 198bhp. An inexpensive Mercury Medalist series was added in 1956 and in 1957 the standard power unit was a 255bhp. Mercury cars became bigger and more expensive in 1958 and 1959 to avoid clashing with the Edsel range from the same stable, and a 6.3-litre, 360bhp engine was available in Mercury cars.

In 1961 Mercury cars broke with tradition, and offered for the first time something other than a V8; not only was there the option of a 3.6-litre six in the regular Mercury car range, but there was also a semi-compact Mercury car, the 2.4-litre Mercury Comet, a Mercury car with a 9ft 6in wheelbase parallel with Ford’s Falcon. The Mercury Comet sold for $2.084 in 1962, when the largest of the standard V8s was a rather modest 4.8-litre. 1963 saw a return to bigger things on Mercury cars, with 6.4-litre and 6.8-litre engines available in the top-price Mercury Monterey models, which also included a Breezeway sedan with forward-sloped rear window as already used on Ford of Britain’s 1960 Anglia. Though the Mercury Comet was retained for 1966 with a 3.3-litre engine, the biggest Mercury cars looked like Lincoln’s Continental on a reduced scale; the wheelbase of the Mercury car is 10ft 3in, with 6.4-litre, 6.7-litre and 7-litre engines available. For the more sporting motorist there was the Mercury Comet Cyclone with compact dimensions and a 6.4-litre V8 unit. A 1967 sports coupé version, the Mercury Cougar, heralded a return to the waterfall-type radiator grille on the Mercury car so generally popular in the early 1950s.

Subsequent Mercury car developments were aimed at keeping station in the tricky medium-priced market, with the sporting element represented by the Mercury Cyclone and Mercury Cougar coupés (with V8 engines of up to 390bhp) and the luxury sector covered by the Marquis Brougham, which in 1969 form aped the Lincoln with its concealed headlamps, and came with 7-litre V8 unit and automatic as standard. Regular family Mercury cars were the Montego on a 9ft 9in wheelbase, and the stock Mercury car of 10ft 4in. In 1971 there was a Mercury edition of Ford’s Maverick compact, the Comet. Wheelbase was 8ft 7in, and engine options of the Mercury car were sixes of 2.8-litres, 3.3-litres or 4.1-litres, or a small 4.9-litre 210bhp V8. Basic price was a low $2.217, and it was continued into 1972 along with the Cougar, Montego, Monterey, Colony Park and Marquis lines, though new Federal regulations took their toll for Mercury cars, and the most powerful engine option gave only 266bhp, as against 375 in 1970. Mercury Montegos had front disc brakes as standard,  as had 1973 Mercury Cougars, which came with a traditional radiator grill in Humber-Sunbeam style. Most of the 1973 improvements on Mercury cars concerned safety (e.g. reinforced bumpers and radial-ply tyres as standard on the big sedans). Ford’s Lincoln-Mercury Division also distributed the German Ford Capri with 2-litre or 2.6-litre engine.
