Karl Benz is honoured throughout the world as the man who designed and built the first workable motor car driven by an internal combustion engine. It is established that in 1885 his first Benz car was ready and made its first trials. Benz’s ideas were concentrated from the beginning on a car as an organic unit of chassis and engine, not on motorization of existing vehicles. The first Benz car was a three-wheeler with two driven rear wheels. The engine was a horizontal single-cylinder with a vertical crankshaft which had a horizontal flywheel. It developed ¾hp and a speed of 8mph is recorded for one of the first trial runs. This prototype Benz car had some featured which are still very extensively used in automobile construction: the water-cooled engine, electric ignition, mechanically operated inlet valve, and a differential gear. This first Benz car still exists and belongs to the Deutsches Museum, Munich, to which it was presented by its inventor. Several Benz Patentwagen replicas were built and are now in different museums.

Only a few Benz cars were produced and for sale in the following years. At the Munich Exhibition of 1888 Benz had the opportunity of showing his improved Benz car to a wider public. Instead of the wire wheels of the first Benz Patentwagen the later models had wooden-spoked wheels. Engine output was increased to 2hp. Sales of Benz’ stationary gas engines were quite satisfactory, while interest in Benz motor cars was very limited and it was not until 1890 that Benz started a real, if small, ‘to order’ production. This was partly a result of exhibiting his Benz car at the Paris World Fair in 1889 which led to increasing sales by his French agent Emile Roger, who already sold Benz stationary engines. The other important factor was that Benz was joined by two new partners in 1890. These two men who possibly saved Benz from the fate of numerous other inventors, driven aground by financial difficulties, were Friedrich von Fischer and Julius Ganss. Fischer took over internal administration and Ganss became responsible for sales. Benz himself was free for further developments on the technical side of the business, which made sound progress. 1893 saw the production of the first 4-wheeled Benz car, the Benz Victoria. This model was also the basis for the first Benz van and Benz bus in 1895; its technical conception was also adopted for the Benz Velo of 1894. This model has a place in the history of motoring as the world’s first production car. Production figures for 1885 to 1893 were 69 cars. 67 cars left the factory in 1894, mainly Benz Velos. These figures increased to 135 cars in 1895 and 181 in 1896.

In 1896 the first Benz Kontra-Motor appeared, an engine with two horizontally opposed cylinders. The first Benz lorry was produced in the same year. In 1898 pneumatic tyres were adopted for the Benz Comfortable. Production in 1899 was 572 cars, which brought Benz into the first rank of car producers. This number was surpassed in the following year with a production of 603 units. The first Benz racing car appeared in 1899 and was the start of numerus racing successes.

After 1901 sales of Benz cars declined as Benz stuck to his now outdated designs. Mercedes’ successes led him to evolve new concepts of construction; the result was the 2-cylinder front-engined Parsifal presented in 1903, available with cardan or chain drive and various engine outputs. In the same year a new 4-cylinder engine appeared and was used in all subsequent Benz models. A 1903 racing car developed 60hp and participated in the Paris-Madrid race. Karl Benz himself left the company in 1903 although he rejoined shortly afterwards. In 1906 he joined his sons in the firm of C. Benz Söhne.

1906 saw Benz gaining a second place in the Herkomer Trial while in the same event in 1907 a 5hp Benz finished first. Second and third place in the Coppa Florio, 1907, first place in the Florida 100-Miles Race, 1908, second and third place in the French Grand Prix, 1908, and second and fourth place in the American Grand Prix, 1908, led the world records which were set with 150hp and 200hp Benz cars by Bruce-Brown, Robertson, Oldfield and Hémery. With the 200hp Blitzen Benz Burman covered a mile in 25.4 seconds from a flying start at Daytona Beach in 1911. This was a speed of 140.8mph, but was not recognized internationally as a Land Speed Record.

In 1910 Benz acquired the Süddeutsche Automobil-Fabrik of Gaggenau. Production of private Benz cars in this factory was given up and in the following years Benz concentrated on commercial vehicles there.

A wide range of Benz cars for sale was marketed in the 1910-1914 period, ranging from the 2-litre Benz 8/20ps up to really big machines like the 10.1-litre Benz 39/100ps, all with side valve engines and shaft drive. However, the 22-litre Benz 200hp (which cost £1800 in England in 1912, and must have been the largest-engined private car to go on the market) had ohv and final drive by side chains. Benz were successful in the Austrian Alpine Trials, the Tatra-Adria Trial and various trials in Russia, to name only a few. The great promoter of German motoring, Prince Henry of Prussia, used only Benz cars.

The first Benz 6-cylinder car was produced in 1914 with the type Benz 25/65ps 6.5 litre. In 1918 the Benz 6/18ps 4-cylinder 1540cc appeared, a type developed during the war. A very important Benz development was the precombustion chamber diesel engine. It was first used in 1922 for Benz Sendling agricultural tractors, and the first diesel-engined lorry by Benz appeared in 1924. These were steps towards later Mercedes-Benz diesel-engined cars. Another idea introduced by Benz which also appeared in later Mercedes-Benz cars was the swing axle. It was one feature of the 2-litre 6-cylinder Benz ‘teardrop’ racing car designed on Rumpler principles. However, this car was not a great success either in its racing or in its sports version. In the Grand Prix of Italy in 1923 they gained fourth and fifth place. In 1924 Benz and Mercedes began to combine their interests, amalgamating in 1926.

Hotchkiss

France, 1903 – 1955

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.
