Austria’s most famous motor car, the Austro-Daimler, was born when Daimler of Cannstatt established a factory in Vienna for the manufacture of about 100 of its Daimler cars annually. The Austro-Daimler was a copy of its German parent. In 1906 the Austro-Daimler concern became a separate financial entity, and a year earlier, Ferdinand Porsche had replaced Paul Daimler at Wiener-Neustadt as director. A new era began, for Porsche was a designer with original ideas. He did not exercise them at once; the two 1909 Austro-Daimler models for sale were large well-made fours with side valves in a T-head and a choice of chain or live-axle drive. World-wide fame came to the Austro-Daimler company with their 1910 models, especially the Austro-Daimler 22/80ps model originally designed to win the Prince Henry Tour of that year. It accomplished this very convincingly. The five large valves per cylinder – one inlet, four exhaust – were actuated by a single overhead camshaft. A combination of well-shaped combustion chambers and light reciprocating parts made for an engine of an efficiency never before seen in a catalogued, non-racing car. Its 5.7-litres produced 95bhp. Even Porsche, however, felt that so much power could not be safely transmitted by a live axle, and chain drive was used initially. The Austro-Daimler 22/80’s small brother, the Austro-Daimler 16/18ps, had a side-valve L-head engine. After it had swept the board in the Austrian Alpine Tour of 1911, the Austro-Daimler 16/25ps Alpine variant was also for sale. In 1914 the range consisted of these three cars, the sv Austro-Daimler 20/30ps, and the luxurious Austro-Daimler 35/60ps also with side valves. Both Austro-Daimler and Daimler sold the Lohner-Porsche, the name given to the electric and petrol-electric cars designed by Porsche before he went to Wiener-Neustadt. The Vienna Austro-Daimler firm was Austria’s largest manufacturer of motorcars.

Immediately after World War 1 a few cars were assembled in Liège from pre-war Austro-Daimler parts by M. Klinkenhammers, and sold under the Alfa-Legia. On their home ground the company returned to high-grade fast tourers. As well as the old ‘Austro-Daimler 16/18’ and ‘Austro-Daimler 20/30’, they made the new Austro-Daimler AD617 for sale, a 6-cylinder car of 4.4-litres with a single overhead camshaft, that was succeeded in 1923 by its development, the Austro-Daimler ADV17/60ps for sale, which was the same but for its front wheel brakes. Four years earlier, Porsche had maintained his reputation for really exciting design by producing the Sascha-type Austro-Daimler, a 1100cc – later 1½-litre – racing voiturette. Its four cylinders, like the six of the Austro-Daimler AD617, were of aluminium, with detachable steel liners. There were two overhead camshafts, however, and dry sump lubrication. The power output was 50bhp. Four-wheel brakes were, of course, fitted.

Although Porsche left Vienna in 1923 to return to Daimler, he was mainly responsible for the new ADM type, which was offered alongside the Austro-Daimler ADV17/60 from that year. The Austro-Daimler ADM1 was basically similar, but had a smaller engine of 2½-litres, and its rounded radiator was a departure for the hitherto traditional Austro-Daimler V-shape. It was sold in sports from in 1925 as the Austro-Daimler ADMII. After 1926, the old Austro-Daimler ADV17/60 was dropped and the ADM engine was enlarged to three litres by increasing the bore. This Austro-Daimler ADMIII in sports form developed 100bhp at 400rpm, and could do more than 100mph. Porsche’s successor, Karl Rabe, designed the even more advanced ADR type. Its tubular backbone chassis and swing-axle independent rear suspension so resembled that of the Tatra that legal action was taken against Austro-Daimler. The Austro-Daimler ADR was available in sports or normal form. At first, the Austro-Daimler ADR used the old ADMIII engine, but the Austro-Daimler ADR6 Bergmeister of 1929, one of the most glamorous Austro-Daimler built, had a new 3.6-litre power unit providing 120bhp. This car was made until production ceased shortly after the Steyr-Daimler-Puch amalgamation in 1934. The Austro-Daimler ADR8, the firm’s first and last 8-cylinder car, designed for more formal bodies, had disappeared in 1933 after a life of three years.

Cadillac

US, 1903 to date

(1) Cadillac Automobile Co, Detroit, Mich., 1903 – 1905

(2) Cadillac Motor Car Co, Detroit, Mich., 1905 to date

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.
