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.

Mors

France, 1895 – 1925; 1941 – 1943

Emile Mors was an electrical engineer, which may account for the ingenious ignition system (by low-tension coil and dynamo) found on his first Mors cars with aiv V4 engines, dry-sump lubrication, water-cooled heads and air-cooled barrels. These power units were rear-mounted, and the belt-and-pulley change-speed gear on the Mors car was in the Benz idiom. Production in 1898 was running at 200 Mors cars a year and front-mounted engines made their appearance on the Mors Petit Duc, an 850cc flat-twin with partial water cooling, cone clutch and final drive of the Mors car was by side chains. Steering was by handlebar and the Mors car cost £294 in England in 1900. The Mors car was still listed in 1901, though later examples were wheel-steered. 

The Mors racing cars designed by Brasier at first rivalled and then surpassed the hitherto invincible Panhards, winning the Paris-st. Malo and Paris-Bordeaux in 1899, following this with victories of Mors cars in the Paris-Toulouse-Paris and Bordeaux-Périgeux-Bordeaux in 1900, and the Paris-berlin and Paris-Bordeaux in 1901. In 1902 the Mors 60hp 9.2-litre competition machines had shock absorbers and in 1903 capacity of the Mors car had gone up to 11.6-litres, with mechanically-operated overhead inlet valves and streamlined bodywork of the upturned-boat type. Gabriel won the Paris-Madrid race on one of these Mors cars, while the Hon. C.S. Rolls recorded 84,68mph over the kilometer at Welbeck on a similar Mors car. The 1904 racers saw a reversion to T-head power units, but this was the last year in which Mors cars made any impression on the circuits. Though Jenatzy drove a Mors car for the team in the 1908 Grand Prix, he took 9th place, and the 2½-litre Mors cars prepared for the cancelled 1914 Coupe de l’Auto never reappeared.

Though full water cooling was not adopted till 1902 on Mors cars, vertical 4-cylinder engines made their appearance late in 1899, followed in 1900 by low-tension magneto ignition. 1901 Mors cars had what amounted to one carburetter per cylinder, with a huge central float chamber. From 1902 onwards the Mors cars followed conventional lines; 1903 Mors carmodels retained the chain drive, but had mechanically-operated sv in a T-head, pressed-steel frames, Dubrulle lubrications and Mercedes-style honey-comb radiators. Brasier had already departed the Mors car company to work for Georges Richard. In 1904 Charles Schmidt, also of Mors cars, went to design European-style cars for Packard in America – this had no connection with the American Mors cars made from 1906 to 1909. Also new on Mors cars in 1904 was the ‘shouldered’ radiator shell which persisted on the Mors carmarque almost to the end. 4-cylinder Mors cars only were made in 1905; they came in 2.3-litre, 3.2-litre, 4.3-litre, 5.7-litre and 8.1-litre sizes, and the largest Mors car, rated at 40/52hp, had an auxiliary transverse spring at the rear and cost £1.224. In 1906 the aluminium water jacketing introduced on Mors cars in 1903 was abandoned, while cone clutches gave way to the contracting-band type which Mors cars never departed from. Ignition was now by high-tension magneto and options included the Huillier windscreen (patented by a Mors car company’s director) and compressed-air starting. A cab-over-engine petrol brougham was listed on the 17hp Mors car chassis. In 1907 L-head monobloc engines arrived with the small 10hp Mors car and 15hp models, which Mors cars also had shaft drive and pressure lubrication: at the top of the range was an 50hp 6-cylinder Mors car with gate change and low-tension magneto ignition and this Mors car sold at £1.375 in England.

The 1908 depression was a blow from which the Mors car company never really recovered, though the company was reconstructed under André Citroën’s management and in 1909 they made 2.000 Mors cars, sales being aided by bigger shaft-driven 2.5-litre and 3.7-litre models. Chain drive and make-and-break ignition were to persiste on the biggest Mors cars until 1912, though there was a shaft-driven 3.6-litre 6-cylinder Mors car in 1911 and the L-head monobloc 12/15hp with 4-speed gearbox was quite popular in 1913/1914. Poppet and Knight sleeve-valve models in great diversity were offered on Mors cars during the last two pre-World War 1 seasons, the latter coming in 2.1-litre, 3.7-litre, 4.4-litre and 7.2-litre sizes with engines by Minerva. By 1914 only the small Mors cars retained sv power units; Citroën double helical bevels were standard, and an sv sports 17/20hp Mors cars was offered with electric lighting. Only Minerva-built Knight engines were used in Mors cars after 1918, the radiators wearing a triple-S monogram as a riposte to Panhard’s double-S (for sans soupages). Mors cars, however, had fewer resources than their former rivals, and not even good looks and a 70mph performance (plus front wheel brakes in 1921) could save the 3.6-litre Sporting 20 Mors car. A 2-litre Mors car, also Minerva-engined, appeared in 1922, but by 1925 most, if not all the Mors car company’s facilities had been absorbed by Citroën. There was a brief renaissance by Mors cars with electric cars during World War 2, but the last vehicles to bear the name of Mors were the Speed motor scooters made from 1952 to 1956.
