W.O. Bentley was already well-known as the importer of the D.F.P. car, a pioneer of aluminium pistons and a designer of successful rotary aircraft engines when his first Bentley 3-litre car for sale appeared at the 1919 London Show. This Bentley model, indelibly imprinted in the layman’s mind as the archetype of the Vintage sports car, had a long-stroke (80x149mm) single ohc engine with fixed head and dual magneto ignition developing about 70bhp in its early form. The Bentley 3-litre was at its best in long-distance events; a team of Bentley 3-litres with flat radiators (the only instance of this apart from the same year’s Indianapolis car) finished 2nd, 3rd, and 5th in the 1922 T.T., and the model accounted for the first two of the marque’s Le Mans wins, those of Duff/ Clement in 1924 and Davis/ Benjafield in 1927 on the badly damaged ‘Bentley Old No. 7’ – one of the legends of motor-racin history. Up to 1929 1.630 3-litres Bentley motorcars were made. 1924 saw the introduction of front wheel brakes and also the famous sports four-seater ‘Bentley Speed Model’ by Vanden Plas. Bentley cars are popularly known by the colours of the enamel on their radiator badges – ‘Bentley Red Label’ signifying a Speed Model short-chassis 3-litre, ‘Bentley Blue Label’ the early short, and long chassis which could and sometimes did carry limousine coachwork, and ‘Bentley Green Label’, a special 100mph Bentley type made  in very small numbers.

In 1926 the Bentley company made a bid for the carriage trade with a big Bentley 6½-ltre six for sale on similar lines. A chassis cost £1.450, but the Bentley image made no impression in this market. However, the model was developed into the 180bhp ‘Bentley Speed 6’ of 1929, considered by many to be the best of the old-school Bentleys for sale, and responsible for the firm’s last two Le Mans wins – Barnato/ Clement in 1929, and Barnato/Kidston in 1930. In 1927 the Bentley 3-litre was developed into the Bentley 4½-litre, still with four cylinder, but with a 100bhp engine which was giving 130bhp by the time production ended. This admirable car could exceed 90mph in standard form, and was used by Barnato and Rubin to win LeMans in 1928. A supercharged version was listed in 1930; it had 182bhp, and did not have the approval of Bentley himself, but it was an excellent if thirsty road car, and won Sir Henry Birkin an unexpected 2nd place in the formule libre French G.P. of 1930. Bentley finances were always shaky, and even Woolf Barnato’s aid of 1927 did not last long; the Bentley company went down in the early summer of 1931 to the accompaniment of a splendid gesture – a 220bhp ohc Bentley 8-litre six, made in two wheelbase lengths, 12ft and 13ft. Only 100 of these eight-litres Bentleys were made, plus 50 examples of a rather uninspired inlet over exhaust valve 4-litre car.

Napier made an unsuccessful bid for the assets of the Bentley company, but were beaten by Rolls-Royce, who introduced their version of the Bentley at Olympia in 1933. This was an entirely different type, based on Derby’s contemporary 3.7-litre ohv push-rod ’20-25’. It had a 4-speed synchromesh gearbox, Rolls-Royce servo brakes, and sold for £1.460 with saloon bodywork. In this form, it could reach 90mph and merited its slogan ‘The Silent Sports Car’. It was not raced, of course, apart from E.R. Hall’s three consecutive second places in the T.T. (1934, 1935 and 1936). By 1936 it had grown into a Bentley 4¼-litre, the increase of capacity being necessitated by the rising weight of bespoke coachwork. An overdrive gearbox was standardized in 1939, and the 1940 Bentley Mk V had independent front suspension, though only a handful were made because of the war. The Derby Bentley car’s swansong was a creditable 6th place by H.S.F. Hay at Le Mans in 1949, on a ten-year-old machine with 60.000 road miles behind it. Cylinder capacity was unchanged at 4.257cc in 1946, but independent front suspension, was standard, and Bentely, like Rolls-Royce, had gone over to inlet over exhaust valves. Prices for the Bentley motorcars for sale rose from £2.997 to £4.474 in 1951 for the standard steel saloon, the first Rolls-Royce product to have a regular series-produced factory body.

Thereafter the Rolls-Royce and Bentley identities merges, though in 1952 there was a special ‘Bentley Continental’ version of the latter with fastback 2-door saloon body by H.J. Mulliner which gave 120mph on a 3.077:1 top gear. Capacity went up to 4.6 litres in 1952 and 4.9 litres in 1955. Automatic transmissions, already optional, became standard that year; power-assisted steering and air conditioning followed In 1957, and for 1960 the old six at long last gave way to a 6.2-litre V8 with full overhead valves, by which time only the radiator style distinguished one make from the other. The ‘Bentley Continental’ with separate chassis was discontinued at the end of 1966; 1972 Bentleys were the 6.745cc Bentley T saloon and the Bentley Corniche 2-door saloon and convertible. Even the price differential between the two sister makes was now a thing of the past, the Bentley T-series selling for the same £10.455 as the Rolls-Royce Silver Shadow.

Hotchkiss

France, 1903 – 1955

(1) Hotchkiss et Cie, St. Denis, Seine, 1903 – 1936

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.
