The ‘Standard of the World’ started humbly as a single-cylinder car selling for $750. Henry M. Leland, its creator, had been associated with Henry Ford and has also built engines for Oldsmobile. The Model-A Cadillac was markedly similar to the early Fords in having a horizontal underfloor engine, 2-speed planetary transmission and central chain drive via a spur-type differential, but Cadillac’s 1½-litre inlet over exhaust power unit had one cylinder where Ford used two. There was no bonnet on the early Cadillac models. This very successful design remained in production until 1908, later improvements including rack-and-pinion steering, transverse front suspension and a dummy bonnet. The Cadillac marque was introduced to Britain by F.S. Bennett, who in 1908 conducted a ‘standardization test’ at Brooklands. Three single-cylinder Cadillac cars were dismantled and the parts mixed up – they were then reassembled and the vehicles run on the track. The R.A.C. awarded Cadillac the Dewar Trophy for this achievement.
A 30hp 4-cylinder Cadillac car with separate cylinders and copper jackets was announced for 1906 and 75.000 of this type Cadillac were sold before it was discontinued in 1914. The original planetary transmission gave way first to a conventional 3-speed box, and finally in 1914 to a 3-speed box with 2-speed back axle. Cadillac was one of the firms organized into the General Motors group in 1909 by W.C. Durant, and in 1910, when a 4-cylinder Cadillac tourer could be bought for $1600, the company was claiming that tolerance on 112 parts of the car were accurate to one-thousandth of an inch. 1912 saw a most important Cadillac innovation: the standardization of the Delco system of electric lighting and starting on the Cadillac, now of 5½-litres capacity and capable of 60mph. The first left-hand drive Cadillac of 1915 was also the first of the company’s V8s, to become as much a hallmark of the breed as were Buick’s overhead valves. Inspired by the De Dion Bouton of 1910 it had 5.1-litre engine and sold for $2700. 13.000 V8 Cadillac cars were sold in the first year of production and the model was widely used by the U.S. Army in World War 1. Cylinder heads were detachable from 1917 on, and 1924 Cadillac versions had Duco cellulose finish and front wheel brakes.
In 1927, when 47.000 Cadillac cars were sold, a less expensive companion make, La Salle appeared, and the cars were restyled in 1928. The synchromesh gearbox made its world debut with the 1929 Cadillac models, which also featured chromium plating and safety glass, with a price range from $3.295 to $5.995. 1930 saw the advent of the ohv Cadillac V16 of 7.4-litres, which gave 185bhp and had a wheelbase of 12ft 4in. This sold at an average rate of 500 Cadillac cars a year for eight seasons in the $6.000-$9.000 price backet. It was joined in 1931 by an equally impressive ohv 6-litre V12 Cadillac for sale. Improvements over the next few years included power brakes (1931), ride control (1932), no-draught ventilation (1933), Dubonnet type independent front suspension (1934) and ‘turret-top’ all-steel bodies (for sale in 1935). 1938 Cadillac models had column change as standard, a year ahead of other GM products, while the V12 and V16 were dropped in favour of a side-valve short-stroke Cadillac 16-cylinder model which was made until 1940. Another new model for Cadillac in 1938, the 8-cylinder Cadillac Sixty Special, anticipated GM’s 1940 styling with its absence of running boards and 4-light sedan bodywork. 5.7-litre side-valve V8s in three wheelbase lengths made up the 1941 Cadillac range, on which Hydramatic transmission was optional for the first time.
The post-war era was to see Cadillac outstrip all its competitors in the top-price class and become an international symbol of wealth. Sales climbed from 66.000 cars in 1941 to 103.857 Cadillac cars in 1950, and to a new record of 165.959 Cadillac cars in 1964. Tail fins made their first appearance on Cadillac’s 1948 fastback coupé, and in 1949 Cadillac, along with Oldsmobile, adopted overhead valves and oversquare cylinder dimensions, their new 5.4-litre engine developing 160bhp. Cadillacs were raced at Le Mans in 1950 by Briggs Cunningham and the Cadillac engine was also used in export editions of Britain’s J2. Allard. Power output increased steadily: 190bhp in 1952 (by which time manual transmission was no longer offered), 210bhp in 1953 (when a 12-volt electric system was standardized), and 230bhp in 1954, the year when panoramic wrap-around windscreens and power-assisted steering became standard on the Cadillac for sale.
The expensive Cadillac Eldorado Brougham of 1957 (it cost over $13.000) was the first car to have air suspension (dropped after a few seasons) as standard equipment, while Cadillac, along with Lincoln, started the fashion for four headlamps, that later became universal in the USA. 1966 Cadillac cars featured GM’s perimeter-type chassis frame, a 340bhp 7-litre engine, variable-rate power steering, full air conditioning, electric door locks and seat controls, a time switch for the headlamps and a six-position steering wheel. Prices started at $4.650. In 1967 Cadillac set a new sales record of 213.161 cars, bettered in 1969 with 266.798/ They introduced a fwd car on Oldsmobile Toronado lines, the Fleetwood Cadillac Eldorado with torsion-bar ifs, self-levelling suspension, and front disc brakes, these last being applied to the more expensive Cadillac Fleetwoods with conventional drive, and to all the 1969 Cadillac range. Capacity of the Cadillac V8 engine was increased – to 7.735cc in 1968 and to 8.2 litres in 1970, but otherwise there were no major changes. In 1973 Cadillac were one of the few firms offering a nine-seater limousine: the Cadillac 75 with a wheelbase of 12ft 7½in and an overall length of 20ft 8in.

Louis Delage, a former employee of Turgan-Foy and Peugeot, started modestly with a conventional shaft-driven single-cylinder 6½hp runabout with a De Dion Bouton engine which was marketed in England as the Baby Friswell. As early as 1906 Delage showed an interest in racing, and the Delage make’s second place in that year’s Coupe des Voiturettes was followed in 1908 with an outright win on a Delage single powered by a Causan-Designed engine. Meanwhile touring Delage cars continued to use De Dion power units, and later 4-cylinder engines of modest capacity built by Ballot, though single-cylinder cars rated at 6, 8 and 9hp were still catalogued by Delage for sale as late as 1910. The 1.4-litre ’Delage 12’ of 1909 was a neat little machine with monobloc cylinders, 3-speed gearbox and fuel tank streamlined into the dashboard, which sold for £230 and was progressively developed up to 1914. This Delage car had a pressure-fed crankshaft in 1910 and was joined in 1911 by a 2.5-litre 30bhp six on similar lines: the footbrake, unusually, worked on the rear wheels. This Delage model had acquired a 4-speed gearbox and electrics by 1914, a version with 11ft wheelbase being listed for town-carriage work.
Delage also pursued his racing career to good purpose, winning the 1911 Coupe de l’Auto with a horizontal-valve 3-litre 4-cylinder Delage which had a 5-speed gearbox with overdrive top. These features were also found on the 6.3-litre Delage cars which won both the 1913 GP du Mans and the 1914 Indianapolis 500-Mile Race, while for the 1914 Grand Prix his 4½-litre Delage cars had twin ohc, desmodromic valves and 4-wheel brakes (but no handbrake). While producing munitions in World War 1, Delage found time to develop a new long-stroke 4½-litre sv 6-cylinder (Delage Type CO), which went into production in 1919 with 4-wheel brakes, but still with a fixed cylinder head. There was also a companion 3-litre 4-cylinder, and by 1921 the Delage CO had developed into the Delage CO2 with ohv, twin-plug head, dual magneto ignition and 88bhp. The 1920s saw a line of excellent fast Delage tourers, while from 1922 to 1927 a costly but very successful Delage racing programme was pursued. Starting with the 6-cylinder Delage I and Delage II sprint cars, the Delage company progressed to an ohv V12 of 10.7 litres’ capacity in 1923, with which René Thomas annexed the World’s Land Speed Record at Arpajon in the following year with a speed of 143,31mph. The Delage car subsequently had a long and distinguished racing career in England. For the 2-litre GP Formula in 1924 Planchon designed a four ohc V12 Delage of great complexity – in twin-supercharged 1925 form it gave 190bhp and won the French and Spanish Grand Prix. Equally costly were the Lory-designed 1½-litre twin-cam Delage straight-8s of 1926 – 1927, with 5-speed overdrive gearboxes and various types of supercharging. In their early days these Delage cars had a bad name for overheating but they were unbeatable in 1927, with five major Grands Prix to their credit. There was also R.J.B. Seaman’s triumphal 1936 voiturette season, when the nine-year-old Delage trounced the ERA and Maseati opposition.
Mainstay of the Delage touring-car programme from 1924 onwards was the classic 2.1-litre 4-cylinder Delage DI for sale, with ohv, 4-wheel brakes, magneto ignition (coil on later cars), 4-speed gearbox and single-plate clutch. For sale at £475 in England it was excellent value and sports versions with aluminium pistons were quite fast. At the same time the Delage company offered the vast 6-litre Delage Type-GL as competition for the Hispano-Suiza: unusual features of this ohc 6-cylinder were the clutched fan, twin oil pumps, X-braced frame and hydraulic servo brakes – it could be bought in England for £1650 in 1925. It was only produced up to 1927. The Delage DI had gone a year later, Delage turning to 6-cylinder cars of more modest capacity: the 3.2-litre ohv Delage DM followed by a less successful sv Delage DR, made in 2.2-litre and 2.5-litre forms. The 1929 Paris Salon saw the first of the big ohv long-stroke straight-8s Delage cars for sale, all with coil ignition, pump and fan cooling, and 4-speed gearboxes. Valve bounce was countered by making the springs operate separate rocker arms. It came in several wheelbase lengths from 10ft 10in to 11ft 11in, and carried superbly elegant if not always practical bodywork. In 1931 it was joined by a 3-litre Delage D6 which was the same car with two less cylinders.
A super-sports Delage D8 was available in 1932: though often overbodied it took its International class 12-hour record at 112mph. The Delage range was further complicated in 1932 by the advent of a new series of short-stroke models, the first of which, the Delage D6-11, had an almost square 2.1-litre 6-cylinder unit, with the Delage D8’s valve gear, independent transverse front suspension and a silent-third gearbox. Inexpensive pressed-steel saloon bodywork was used and the Delage car sold for £595. By 1934 there was not only a companion straight-8 (the Delage D8-15) of 2.7-litres, but also a 1½-litre 4-cylinder version. The big Delage D8s were still listed. 1935 Delages featured synchromesh and hydraulic brakes and slightly undersquare 6- and 8-cylinder engines were used: all Delage cars now had ifs. Louis Delage was, however, forced to sell out to Delahaye and thereafter the Delage cars slowly evolved into more florid versions of that make, built in the same factory. The 4-cylinder cars died out with the obscure 2.2-litre mechanically-braked Delage DI-12 of 1936, a badge-engineered Delahaye. There was an abortive plan to make Delage cars in England in 1937. Up to World War 2 the Delage company’s offerings were the 2.7-litre Delage D6-70 and the 4.3-litre 8-cylinder Delage D8-100 and Delage D8-120. All had hydraulic brakes, Cotal gearboxes and ifs, and the Delage D6-70 could be bought in England for £695. This Delage was raced to some purpose, winning the 1938 TT and taking second place at Le Mans in 1939, in which year capacities of both engines were increased. The 3-litre 6-cylinder car appeared after the war, but only a few were made, and Louveau’s and Jover’s second place at Le Mans in 1949 was almost the last that was heard of Delage. Along with Delahaye, Delage was aborbed by Hotchkiss in 1954.
