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.

Stoewer

The Stoewer car factory developed out of the Stoewer ironworks and was among the pioneers of the German car industry. After manufacturing motor cycles, tricycles and quadricycles for two years, Stoewer turned to cars in 1899. The first Stoewer car had a rear-mounted 2-cylinder engine. 4-cylinder Stoewer cars followed in 1901, and electric Stoewer cars were also produced. Best known were the 2-cylinder Type T Stoewer car (2.280cc and 3/12PS), the 4-cylinder Stoewer P4 (3.052cc and 11/22PS), the Stoewer G4 (1.500cc and 6/12PS) and the 6-cylinder Stoewer P6 (8.820cc and 34/60PS), evolved in the 1905-1907 period all Stoewer cars with shaft-drive. The Stoewer B1 of 6/16PS and the Stoewer B6 of 9/22PS which appeared in 1910 were also built by Mathis under licence. The G4 Stoewer car was the basis for the Stoewer B5, which Stoewer car in 1912 became famous by setting up a record at Brooklands with 67.7mph. The new range of Stoewer cars which appeared in 1913 was also based on successful earlier cars. They were the Stoewer C1 (6/18PS), Stoewer C2 (10/28PS) and C3 Stoewer car (6-cylinder and 19/45PS). Shortly before the outbreak of World War 1 the Stoewer car range was headed by the F4 Stoewer car with a 4-cylinder, 8.8-litre 33/100PS ohc engine. After the war an enormous Stoewer car appeared, the Stoewer D7, using a 6-cylinder 11.2-litre 42/120PS aero engine, as well as some conservative sv 4- and 6-cylinder Stoewer cars with rear wheel and transmission brakes. Front wheel brakes appeared on Stoewer cars in 1925. Stoewer introduced 8-cylinder Stoewer cars in 1928. These were the Stoewer Superior, Stoewer Marschall, Stoewer Gigant and Stoewer Repräsentant with engines ranging from 2-litres and 45bhp to 4.9-litres and 100bhp. The Stoewer car firm re-entered the economy class in 1931 with the V5, a front-driven Stoewer car with a V4 1.188cc engine, followed by the front-drive models R140 (1.369cc), R150 (1.488cc) and R180 (1.769cc). Another 8-cylinder was the front wheel drive Greif V8 with a 2.488cc engine, which was replaced by the conventional 6-cylinder 3.609cc Arcona Stoewer car in 1938. In 1934 the 1½-litre 4-cylinder Stoewer car and 2½-litre V8 Stoewer car were shown at the Brussels Salon by Monsieur Dewaet under the name D.S. (Dewaet-Stoewer). The Greif Junior was built under Tatra licence with an opposed 4-cylinder 1.474cc engine. It succeeded the Röhr Junior. In the middle of the range was the Stoewer Sedina with a 4-cylinder engine of 2.4-litres.

Production of private Stoewer cars was given up at the outbreak of World War 2 in 1939. The Stoewer car factory was destroyed during the war and production of Stoewer cars was not resumed.
