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.

At first the Tatra car was a continuation of the Nesselsdorf, producing the pre-war Types T and U Tatra cars, the latter a 6½-litre ohc 6-cylinder. The first real Tatra car of 1923 was completely different from the last Nesselsdorf models. After his return from Steyr, Hans Ledwinka produced a car which became one of the classics in the history of automobile design. This Tatra car was characterized by an air-cooled opposed-twin engine of 1.056cc developing 12bhp, a central tubular frame, and special rear swing axles and differential. It was known as the Type 11, and was the basis of later Tatra car models, commercial vehicles as well as private Tatra cars. Type 12 was identical with the Type 11, but this Tatra car had 4-wheel brakes. The Tatra car design was not intended for sporting events, but nevertheless two of these Tatra cars participated in the 1925 Targa Florio and gained 1st and 2nd place in the 1.100cc class, driven by Fritz Hückel and Kart Sponer. These were standard production Tatra cars, except that two inlet valves instead of one were fitted, and the front transverse-leaf springing was replaced by swinging half axles. Josef Vermirovsky was another competition driver on the small Tatra carmodel; his successes with Tatra cars included winning a 5.000 kilometre (3.107 miles) trial from Leningrad via Tiflis to Moscow in 1925. About 25.000 Tatra cars of Types 11 and 12 were built up to 1930. Some 4-cylinder Tatra cars followed, built on the same lines with air-cooled opposed engines, central tubular frames and swing axles: the Tatra 30 (1.680cc, 40bhp) and Tatra 52 (1.910cc, 40bhp). There were also the in-line 6-cylinder Type 70 Tatra car of 3.400cc and 60bhp, and the 6-litre V12 Type 80 Tatra car with 100bhp, both featuring the same frame construction and swing axles. The Type 80 Tatra car was built only in limited numbers, like the single-cylinder, 528cc 3-wheeler Tatra car (Type 49).

The next important development was the Tatra 57 which appeared in 1932. This Tatra car had the central tubular frame and swing-axles which were traditional by this time, and an air-cooled opposed 4-cylinder engine of 1.160cc developing 22bhp. Engine capacity of the Tatra car was later increased to 1.690cc, and this Tatra car was built until 1938. The German Röhr Junior was the Tatra 57 design built under licence. Under the name of Austro-Tatra the light Tatra cars were also manufactured in Vienna.

Ledwinka and Tatra were destined to make automobile history again with the Tatra Type 77 of 1934. The all-enveloping body of the Tatra car was built strictly to aerodynamic principles. A central box-type frame was used, and in its forked rear end – behind the rear axle – an air-cooled V8 engine of 3.400cc was placed. It developed 70bhp and gave the Tatra car a maximum speed of 95mph. The 1937 Tatra 87 incorporated the same technical principles and this Tatra car used a basically similar body. Engine capacity of the Tatra car was reduced to 2.960cc; output was 75bhp – a result of weight reduction. This Tatra car was capable of 100mph. In the same year the Tatra 97 was introduced with the same body, but an opposed 4-cylinder unit of 1.760cc and 40bhp was fitted. After the district of Koprivnice had come under German occupation, and the restriction of numbers of types which had been introduced in Germany in the 1930s was enforced in Czechoslovakia too, production of the Tatra 97 ceased and only the 87 Tatra car was continued until about 1941. In 1945, after the war, the Tatra car factory were nationalized by the Czechoslovak government, and production of Tatra cars was devoted to the front-engined Type 57B Tatra car and the rear-engined Tatra Type 87. These Tatra car were replaced in 1948 by a single model, the 2-litre rear-engined Tatraplan, derived from the pre-war Type 97 Tatra car. This Tatra car was made until 1954, after which there was a three-year period when no private Tatra cars were made. In 1957 the Tatra 603 was introduced; this Tatra car again had an air-cooled V8 engine of 2.472cc mounted in the rear. The Tatra car is still in production today as the T3-603, with twin-carburettor engine, servo-assisted disc brakes, and powere assisted steering, although Tatra concentrate on commercial vehicles and railway carriages. In preparation for 1973 was the 3.4-litre T613, a development of the existing theme.
