The Delahaye firm was established in 1845 and initially produced brick-making machinery, later launching out into stationary engines. The first Delahaye cars were very much on Benz lines with slow-running, rear-mounted horizontal engines and belt transmission. Radiators and frames were tubular; Archdeacon and Delahaye himself took 4th and 6th places respectively in the Paris-Marseilles-Paris Race of 1896, though the Delahaye firm took little interest in competition and their last appearance was in the Paris-Vienna (1902). By contrast, Delahaye were very interested in commercial vehicles, which made their debut in 1898 and bulked larger and larger in later years. In 1898 a 1.4-litre single and twins of 4½hp and 6hp were being made, the Paris Delahaye works were opened, and Charles Weiffenbach joined the Delahaye firm as Chief Engineer, a post he was to retain until after World War 2. By 1899, 600 Delahaye cars had been delivered, and production was running at 20 Delahaye’s a month. Emile Delahaye himself retired in 1901, when wheel steering was standardized, though the old belt-driven designs were still catalogued as late as 1904, and there was even a short-lived 1902 Delahaye model with front vertical engine and belt drive. More advanced was Delahaye Type 10B, a 2.2-litre 4-cylinder, still with aiv, but with Panhard styling, final drive by side chains, and detachable cylinder heads; this was followed by a bigger 4.4-litre Delahaye car said to develop 28bhp.

In 1904 detachable heads were found on both the 2.7-litre Delahaye Type 15B twin at £420, and on a big 4.9-litre 4-cylinder Delahaye car which also had a water-cooled exhaust system. T-head engines, gate change, and ht magneto ignition made their appearance in 1905, when the range included two twins and three 4-cylinder cars, the largest an 8-litre. The King of Spain bought one of these big Delahaye cars, with two hand and two foot brakes, and a foot-operated decompressor, in 1906. In 1907 licence-production of the Delahaye make was undertaken in Germany by Presto, transverse rear suspension was featured, and the small 2-cylinder model acquired shaft drive. In the usual French tradition L-head Monobloc engines appeared in 1908 on the 1.9-litre 12/16hp (Delahaye Type 32), but the chain-driven cars were listed as late as 1911. An even smaller 1.2-litre 4-cylinder Delahaye sold for £240 in 1909, and the new monobloc engines were used by White in America as the basis for their first petrol car, the 20/30. 1911 brought an interesting departure in the shape of the 3.2-litre Delahaye Type 44, a blockcast V6 with 4-speed gearbox. It sold for £470 in England, and this Delahaye was still being made in 1914. A 4-cylinder car was used for tests with the Parry Thomas electric transmission. Apart from such ingenious features as pressure lubcrication to the spring shackles, the other 1914 Delahaye models were conventional monobloc 4-cylinder machines, available with detachable wheels and electric lighting. They came in 1.6-litre, 2.3-litre, 2.6-litre, 3-litre, 4-litre and 5.7-litre sizes, all but the smallest with 4-speed gearboxes.

After World War 1 the Delahaye company settled down to 14 years of stodgy, dependable, and uninteresting cars, now with full electrical equipment and V-radiators, though at first the foot-operated transmission brake was retained. 4-cylinder Delahaye models were sold with 2.6-litre and 3-litre sv engines, but there was also a 4.1-litre six (Delahaye Type 82), with the unusual combination of detachable head and valve caps, which acquired front wheel brakes in 1921. All other Delahaye models were so equipped by 1925, but in the meanwhile the firm was ringing the changes on a complicated and dull range which included a 1.8-litre in sv and ohv versions, and two bigger inlet over exhaust fours, the 2.4-litre Delahaye 15/35hp and the 2.9-litre Delahaye 18/40hp. 4-speed gearboxes, pump cooling, and wooden wheels were regular features. In 1927 Delahaye formed a consortium with Chenard-Walcker, Donnet and (for a short while only) Unic, which was supposed to rationalize production, and did to the extent that it was hard to distinguish the 6-cylinder Delahaye for sale from its Chenard-Walcker counterpart, though the former had full overhead valves and the latter inlet over exhaust. These sixes appeared in 1928, the Delahaye cars coming in 2.5-litre and 2.9-litre sixes, with magneto ignition up to 1929, and coil thereafter. 1929 was also the last year for the V-radiatored Delahaye for sale, which gave way to an American-style ribbon-type. In 1930 there were also two 4-cylinder models, the smaller a straight-forward sv 1½-litre (Delahaye Type 109), which was still listed in 1932. A bigger 6-cylinder for sale (Delahaye Type 126) pointed the way to better things, and in 1934 independent front suspension was offered on the 2150cc Delahaye Super 12 4-cylinder and on the Delahaye 18CV Superlux, an ohv 6-cylinder which was also available with a Wilson gearbox.

In 1935 Delahaye bought the ailing Delage company, and in 1936 Delahaye were supplying 2.2-litre ohv 4-cylinder engines to Amilcar for installation in that firm’s Pégase model. More important, they had come out with two exciting 6-cylinder sports Delahaye models, both with ohv push-rod engines, independent front suspension, Bendix brakes, and synchromesh or Cotal gearboxes; the 3.2-litre Delahaye Coupe des Alpes had 110bhp, and the 3.5-litre Delahaye Type 135 120bhp. Both were capable of over 100mph in standard form, and the Delahaye 135s proceeded to take 2nd, 3rd, 4th and 5th places in the 1936 French Sports Car Grand Prix, following this up by wins in 1937 and 1939 Monte Carlo Rallies, and at Le Mans in 1938. A Delahaye type 135 also won the controversial ‘Fastest Sports Car Race’ at Brooklands in 1939, where the opposition included a 2.9-litre Alfa Romeo. There was a long-chassis version of Type 135, the Delahaye Type 148, and in 1937 came the Jean Francois-designed Delahaye Type 145, a short stroke 4½-litre ohv V12 with Cotal gearbox and De Dion rar axle; its output was 238bhp, and the two-seater was capable of 165mph. Delahaye tried very hard with this car during the 1938 GP season, even beating Mercedes-Benz at Pau, as well as finishing 4th in the Mille Miglia – a remarkable double. The Delahaye was outclassed, however, and even more so in 1939, despite the introduction of a single-seater version. A very few ‘cooking’ V12s with conventional rear axles, hydraulic brakes, and exotic roadster coachwork were sold by Delahaye in 1939 at £1485; though the 135 continued to do well.

During World War 2 Delahaye joined Baron Petiet’s G.F.A. (Groupe Francaise Automobile) selling organization, these initials appearing on the radiator badges of all post-war Delahaye cars, though the group ceased production in 1952. Production of the 4-cylinder Delahaye 134 as well as the Delahaye 135 was resumed in 1946, though the former did not last long. Output of the sports cars was now 130bhp, and narrower, more ornate radiator grilles were used. In 1948 came the 4½-litre Delahaye Type 175 series with hydraulic brakes; output was quoted as 185bhp, but they were not a success and were dropped from the range in 1951. Penal taxation was in any case making life difficult for France’s quality-car makers, and combined Delahaye and Delage sales dropped from 483 in 1950 to only 77 in 1951. In which year Delahaye won the Monte Carlo Rally for the second and last time. It also marked the introduction of the Delahaye company’s last new designs – a Delahaye jeep-type 4x4 with all-round independent suspension, and an improved 3½-litre, the Delahaye Type 235 with aerodynamic bodywork, its output increased to 152bhp, and still with mechanical brakes. The marque was still exhibiting at the Salon in 1953, but the following year Delahaye merged with Hotchkiss, and under the new management only trucks were made. After 1956 these too only bore the name of Hotchkiss.

Riley

GB, 1898 – 1969

(1) Riley Cycle Co Ltd, Coventry, Warwickshire, 1898 – 1912

(2) Riley (Coventry) Ltd, Coventry, Warwickshire, 1912 – 1948

(3) Riley Motors Ltd, Abingdon, Berks., 1948 – 1969

The first Riley car was a small single-cylinder belt-driven voiturette which Riley car did not go into production. Motor Riley tricycles followed n 1900, and a handlebar-steered Riley tricar with 2 forward speeds, and a 517cc engine with mechanically-operated inlet valves in 1903. Riley Tricars were made until 1907, later examples of these threewheeled Riley cars being twins with driver’s seats in place of saddles, water cooling and wheel steering. The 1.034cc V-twin engine was also fitted to the Riley car company’s first 4-wheelers, which Riley car had amidships-mounted power unit with their gearboxes alongside and chain drive, and the Riley car sold for £168. Bigger V-twins of 2-litres’ capacity, more conventional layout and round radiators were made from 1908 onwards. These Riley car incorporated pressure lubrication, shaft drive, constant-mesh 3-speed gearboxes, and Riley’s own patent detachable wheels, the demand for which brought Riley car production almost to a standstill and was responsible for the formation of the new Riley car company in 1912. In 1914 the 2-cylinder Riley cars were still being made, but there was also a new 2.9-litre sv monobloc four Riley car with worm drive, which was offered again after World War 1 by the Riley engine Co, though this Riley car soon disappeared from the market.

The first post-war 1 Riley cars were the Riley Elevens with sv 1½-litre 35bhp engines, alloy pistons and full electrical equipment which Riley cars were selling £550 in 1920, acquiring spiral bevel final drive in 1921. The Redwinger sports version of the Riley car, with wire wheels and polished-aluminium coachwork appeared in 1923, offering 70mph for £450, and the sv Riley cars were continued until 1928, with a 1.645cc engine and the option of front-wheel brakes in 1925. One of these Riley Twelves was used to prospect Kenya’s road system in 1926, and in 1927 there was even a supercharged development Riley car of the Redwinger available, though this Riley car was overshadowed by Percy Riley’s advanded new Riley Nine, with a 1.987cc 32bhp 4-cylinder engine, twin camshafts and high push-rods, a unit which was to form the basis of all Riley car designs made up to 1957.

In 1928 came the handsome Riley Monaco fabric sports saloon version at £298, a best-seller Riley car from the start, and the lowered and tuned Riley Brooklands sports, inspired by the late J.G. Parry Thomas, which Riley car weighed 1.120lb, had a twin-carburettor 50bhp engine, and was capable of 80mph, all for £395. A twin carburettor variant of the touring Riley Nine followed in 1929, along with a new 1.6-litre 6-cylinder Riley Fourteen of similar styling at £495.

Riley cars had a distinguished competition record in the following years: class wins with a Riley car in the 1929, 1930, and 1931 Tourist Trophies were followed by Whitcroft’s outright victory in 1932, while two more wins were recorded by F.W. Dixon on the later 1½-litre 4-cylinder Riley car in 1935 and 1936. A 4th place at Le Mans in 1933 led to 2nd, 3rd, 5th, 6th, 12th and 13th places in 1934, not to mention three successive wins – 1934, 1935, and 1936 – in the BRDC 500 Mile Race at Brooklands. Leverett won the light-car class of the 1931 Monte Carlo Rally on a Riley Nine, while the 6-cylinder racing Riley cars of 1933-1934 formed the genesis of the ERA, and nearly twenty years later the late Mike Hawthorn was to make his name in Club Racing on sports Riley Nines and 1½-litres. Both the Riley Nine and the Riley 14/6 were progressively developed, the former Riley car acquiring vacuum feed in 1931, a lowered chassis and semi-panelled bodywork in 1932, and an optional (later standard) preselector gearbox in 1934. A super-sports 6-cylinder 1½-litre Riley car with water-cooled centre main bearing appeared in 1932, being followed in 1933 by the touring Riley Mentone version at £348. 1933 also brought two advanced body styles of Riley cars, the fastback Riley Kestrel saloon (listed up to the end of the old Riley car company in 1938) and the more-conservatively styled Riley Falcon on which the doors opened into the roof. A Salerni automatic transmission was offered on the 14/6 Riley car, but did not go into regular production.

Two handsome sports two-seater variants Riley cars were listed in 1934/ 1935, the Riley 9hp Imp on a 7ft 6in wheelbase and the 1.654cc 6-cylinder Riley MPH which gave over 90mph for £550, while a newcomer in 1935 was the classic 1½-litre Four Riley car with Wilson gearbox, rod-operated Girling brakes and centralized chassis lubrication, a best-seller in its class at £335, and available in single- and twin-carburettor versions: subsequent developments were the 85mph Riley Sprite two-seater and the Riley Kestrel-Sprite and Riley Lynx-sprite saloon and tourer which offered more room but the same highly-tuned engine for £398. A cheaper Riley Nine, the Riley Merlin with pressed-steel bodywork, came on the market in 1936, along with the 1½-litre, a 6-cylinder 15/6 Riley car, and a 2.2-litre V8 Riley car, of which very few were made, the engine of the V8 Riley car made up of two 9hp blocks. 1937 Riley Nines came with new 6-light Riley Monaco bodies and twin-carburettor 42bhp engines as standard, while other new models of Riley cars were an abortive 3-litre luxury V8 made by a subsidiary company, Autovia Cars, and a more successful long-stroke 2.4-litre Big Four Riley car on classic lines, with an 85bhp engine and Borg-Warner 3-speed synchromesh gearbox incorporating an overdrive at £385. Overdrive was optional on 1938 1½-litres Riley cars.

Finances, however, were insecure and the Riley car company were acquired by the Nuffield Organization later in that year. Under the new management only the 1½-litre and the Big Four Riley cars were continued, with disc wheels, conventional synchromesh gearboxes and Wolseley-like bodywork. The post-World War 2 successors Riley cars used the same engines, but were altogether more handsome Riley cars with independent torsion-bar front suspension and fabric tops, the bigger engine’s output being boosted first to 90bhp and then to 100bhp: this Riley car unit was also used by Healey in the 1946 – 1954 period, while some open three-seater versions with column change were made by Riley cars for export. Hypoid back axles and full hydraulic brakes were incorporated in 1952 Riley cars.

After the Nuffield-Austin amalgamation the 1½-litre Riley car was continued into 1955 with relatively little change, but the 1954 2½-litre Riley Pathfinder shared its bodywork with Wolseley’s 6-90, the new chassis being a BMC design with coil rear suspension and cam-type steering. Even this disappeared after 1957 in favour of a version with a 2.6-litre 6-cylinder ohv BMC engine, and subsequent Riley cars were merely luxury versions of BMC themes, starting with the Riley One-Point-Five (basically a Wolseley 1500), and working through variations of the Farina-styled 1½-litre and 1.6-litre saloon Riley cars, the Mini, and, from 1966, the 1100/1300 family with Hydrolastic suspension, known in Riley cars guise as the Kestrel. Riley’s Mini, the Riley Elf, had a built-out boot and (from 1963) a 998cc engine in place of the standard 848cc Austin/ Morris type. This meaningeless badge-engineering was stopped by British Leyland in 1969.
