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.

Stutz

US, 1911 – 1935

(1) Ideal Motor Car Co, Indianapolis, Ind., 1911 – 1913

(2) The Stutz Motor Car Co of America, Indianapolis, Ind., 1913 – 1935

The Ideal Motor Car Company was the name of the firm which made the first racing Stutz cars, but it was changed to the Stutz Motor Car Company in 1913. Harry C. Stutz’ most famous passenger Stutz car was the Stutz Bearcat speedster of 1914 – this Stutz car is probably the best known of all American sports cars. The Stutz car followed the usual recipe of a low-hung chassis, a big, slow-turning proprietary engine (in this case, a T-head, 4-cylinder Wisconsin unit, producing 60bhp at 1.500rpm), and very little else, just a bonnet, wings, raked steering column, two bucket seats, and a fuel tank behind them. A Stutz-made 3-speed gearbox was integral with the rear axle; an uncommon feature. This component had been sold by the Stutz car company before he made complete Stutz cars. A 6.2-litre 6-cylinder engine was available on the Stutz car, but seldom seen. The Stutz Bearcat was the most popular of its breed, in spite of its high price, and the appeal of the Stutz car was boosted by Stutz cars successes with ohc, 16-valve racing cars. The Stutz car was the Mercers’ greatest rival. Touring Stutz cars were made as well, but these Stutz cars were comparatively little known. Total production grew from 759 Stutz cars in 1913 to 2207 Stutz cars in 1917. Two years later, Stutz left to make another car, the HCS, although the cheaper Stutz cars of the 1915 period were also known as H.C.S. The gearbox was moved back on the Stutz car to the normal position in 1921, and shortly after this Stutz cars began making their own engines: an sv four giving 88bhp and a 75bhp ovh six. The latter was developed to give 80bhp in the 4.7-litre Speedway Six Stutz car of 1924, the last Stutz car of the old line.

In 1926, there was a change of management within the Stutz car company, and Frederick E. Moskovics, the new president, initiated a radiacally new Stutz car policy. Paul Bastien, who had designed the splendid 2-litre Métallurgique from Belgium, was responsible for the Stutz AA, or Vertical Eight Stutz car. This Stutz car was a beautifully-made fast tourer, more typical of Europe than America. Its specification embraced a straight-8 4.7-litre engine with a single overhead camshaft, and dual ignition, including two plugs per cylinder. Power output of this Stutz car was 92bhp at 3.000rpm. This was a modern, reasonably efficient engine by any standards, and the Stutz car was distinctly advanced in these respects by American standards. There were, however, only 3 forward speeds on the Stutz car. The hydraulic brakes were very good indeed, and the underslung worm final drive allowed the fitting of low-built, good-looking bodies on Stutz cars. Centralized chassis lubrication and safety glass were provided. Glamorous though the AA Stutz car was, the Stutz car was sold on the slogan of ‘The Safety Stutz’, and a year’s free passenger insurance was given with each Stutz car. In 1927, the engine of the Stutz car was enlarged to 4.9-litres, now giving 95bhp, and a speedster option, the Stutz Black Hawk, was added. In the following year, Weymann fabric body construction was adopted on Stutz cars; another European touch. The engine of the Stutz car was enlarged again in 1929 and this made 113bhp available. Better still, this Stutz car had 4-forward speeds. Special Stutz Black Hawk speedsters were 2nd at Le Mans in 1928, but the Stutz cars came no higher than 5th in 1929. These Stutz cars had Roots superchargers and vacuum servo brakes. This Stutz car was put on sale as the Stutz Bearcat, reviving a famous name. Stutz cars also competed at Le Mans in 1930, 1931 and 1932. Unfortunately, a Stutz car lost a well-publicized challenge match at Indianapolis with a Hispano-Suiza, and Frank Lockhart was killed at Daytona Beach while trying to take the World Land Speed Record with a Miller-engined car built by the Stutz car company, both setbacks taking place in 1928.

Sales of Stutz cars fell, and a range of cheaper Stutz carmodels with, it was hoped, wider appeal was introduced for the next year, alongside the existing Stutz car range. These Stutz cars had little in common with the classic models, so were called Black Hawks, not Stutz cars. One used a 6-cylinder, ohc engine of 4 litres’ capacity made by Stutz car company, and the other a straight-8 sv unit by Continental. At the other end of the scale, there appeared in 1931 the superb DV (dual valve) 32 Stutz car, to compete with the new multi-cylinder Stutz cars being brought out by Lincoln, Cadillac, Marmon, and others. The Stutz car design was basically similar to that of the SV16 Stutz car, still current, but there were two overhead camshafts and four valves per cylinder: 32 Stutz cars in all. The DV32 Stutz car was listed in speedster form, as the Stutz Bearcat, and, on the shorter chassis, as the Stutz Super Bearcat. These stubby, formidable Stutz cars were guaranteed to exceed 100mph. The expensive, high-quality, specialist Stutz went the way of most of its kind in the Depression years. Intead, the Stutz car company sold, and later made a light delivery van, called the Pak-Age car. This had a rear engine and all-independent suspension, and was current from 1928 to 1938, after which manufacture was taken over by Diamond T.

US, 1970 to date

Stutz Motor Car of America, New York, N.Y.

Unlike replica cars such as the Auburn and Cord, the makers of the Stutz Blackhawk coupé merely borrowed the name of the pre-war Stutz car for their machine. The Stutz car was powered by a 6½-litre Pontiac V8 engine stripped and modified so that the original output of 365bhp was raised to 425bhp. This was mounted in a modified Pontiac chassis, and the Virgil Exner-designed body was hand-built by Carrozzeria Padana of Modena, Italy, where the final assembly of the Stutz cars was done. The first Stutz car model, the 2-door hardtop, was priced at $22.500; a new Stutz car model for 1972 was a 4-door saloon using an long wheel base Cadillac chassis, and selling for $31.250.
