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.

Horch

August Horch was among the pioneers of car manufacture in Germany. He was employed as a an engineer with Benz from 1896 to 1899 when he started his own Horch car factory at Cologne. The first Horch car appeared in 1900. This Horch car had a 2-cylinder 5hp front-mounted engine and shaft drive. The next Horch models were a 2-cylinder 10/12hp and a 4-cylinder 16/20hp. After the Zwickau works had been set up in 1904 Horch was able to increase production. The Horch 18/22hp ohv 4-cylinder model of 1904 became very popular and was the basis for several subsequent Horch cars. A victory in the Herkomer Trial of 1906 was gained with this Horch car model, the first such success for a Horch. Horch also pioneered with his Horch Torpedo form aero-dynamic bodies for the Prince Henry Trials, which were built by Kathe of Halle. In 1906 a 6-cylinder 8-litre power unit was designed for Horch cars, developing 60bhp, but it was not a success and this was one cause of differences between Horch and his partners. Horch himself left the firm and started the Audi factory.

Various models with different engine sizes were included in the Horch car range, from the small Horch 6/18PS 1.588cc to the Horch 25/60PS 6.395cc. All Horch cars had 4-cylinder engines. After World War 1 the Horch 33/80PS 8.440cc model appeared, which had actually been designed in 1914. This Horch car started a series of prestige cars for which the make became famous in the following years. Paul Daimler (son of Gottlieb) was engaged as chief engineer in 1923. Ohc 4- and 6-cylinder Horch car models with fwb appeared in 1923/ 1924, but the first new Horch car under his management was the Horch 300 with a straight-8 3.230cc engine with twin overhead camshafts. In 1927 the ‘Horch 305’ and ‘Horch 306’ appeared, which also featured straight-8 engines, with twin overhead camshafts and a capacity of 3.375cc developing 75bhp. These Horch car models differed only in wheelbase. They were followed by the ‘Horch 375’ in 1928 with an 8-cylinder 3.974cc engine capable of 80bhp. After Daimler left Horch two more models (the Horch ‘400’ and ‘405’) were produced showing Daimler influence. The Horch 450 of 1930 was entirely new. This Horch car was straight-8 with only one overhead camshaft. Two different wheelbases and engines of 4, 4½ and 5 litres were available. The last of these stayed in the Horch car range until 1939, later Horch cars having 10-bearing crankshafts and all round independent suspension. Type numbers of Horch cars became a little confusing in the next few years, when some models were available with different wheelbases and engine capacities. A V12 with 5.990cc (Horch car models ‘600’ and ‘670’) appeared in 1931, followed by the V8 3.517cc ‘Horch 830B’ in 1933, available in two wheelbase and engine sizes. By 1939 the range consisted of the ‘Horch 930V’ and ‘Horch 830BL’(3.823cc, 92bhp) and the ‘Horch 951A’, ‘Horch 853A’ and ‘Horch 855’ (4.944cc, 120bhp). These Horch car models were available with different wheelbases and a variety of body styles from a two-seater roadster to a large Pullman saloon. The Horch car company was celebrated for luxurious ‘prestige’cars which were sold at lower prices than other top makes; a V8 cost £615 in England, and straight-8s from £985.

From 1932 Horch was a member of the Auto Union, and the racing cars bearing this name were built in the Horch car works. In 1945 the Horch car factory was nationalized and in 1956 it brought out a new Horch car. This had to be sold as the Sachsenring, as Auto Union, now based on Düsseldorf, hold the sole rights to the brand-names Horch, Audi and Wanderer.
