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.

Marmon

US, 1902 – 1933

(1) Nordyke and Marmon Co, Indianapolis, Ind., 1902 – 1925

(2) Marmon Motor Car Co, Indianapolis, Inc., 1926 – 1933

Howard Marmon’s first cars were advanced machines, featuring air-cooled V4 engines of oversquare dimensions, with mechanically-operated overhead valves and pressure lubrication. Something approaching independent front suspension was achieved on Marmon cars by the use of double-three-point suspension, with a separate sub-frame for engine and transmission. Only the 2-speed gearbox of planetary type conformed on the Marmon cars to American practice of the period. These Marmon cars persisted until 1908, though 1907 brought the introduction of selective sliding-type gearboxes on the Marmon car and a short-lived 60hp V8. In 1908 buyers of Marmon cars had the choice of air or water cooling and cylinder heads were detachable. The following year Marmon went over to conventional T-head in-line fours rated at 40/45hp and 50/60hp, and two years later only the 5.2-litre Model 32 Marmon car with rear-axle gearbox was listed. Marmon cars did well in contemporary competition, with 54 1st places logged with a Marmon car between 1909 and 1912; Ray Harroun won the first Indianapolis 500 in 1911 with a specially-built 6-cylinder Marmon car, the well-known Marmon Wasp. An enormous 9.3-litre six rated at 48hp was available in 1914.

In 1916 the advanced ohv 6-cylinder Marmon 34 with aluminium cylinder block, body, bonnet and radiator shell, and double transverse rear suspension was introduced. The engine capacity of this Marmon car was 5½-litres, and its output 74bhp; developments of this Marmon car were still listed as late as 1927, acquiring Delco coil ignition in 1920, and the option of a Marmon car with front wheel brakes in 1923. The Marmon cars were expensive: $5.000 was asked for a touring car in 1921. A not very successful 3.1-litre ohv straight-8 in the Marmon car appeared in 1927, but the following season only Marmon cars with eights were made, the cheapest sv Marmon 68 selling for $1.395. In 1928 Marmon also entered some front-wheel-drive Marmon cars at Indianapolis, but they were in fact only revamped Millers. The Marmon car company sold 22.300 Marmon cars in 1929, thanks to a cheap new straight-8 at under $1.000, the Marmon Roosevelt. This brandname, however, did not last, for the Marmon car appeared in the 1930 programme as the Marmon R, along with three other eights, the sv 69, and two big ohv Marmon cars with 4-speed gearboxes and capacities of the 4.9- and 5.2-litres respectively.

Marmon cars swansong was the magnificent 9.1-litre 200bhp 16-cylinder model of 1931. This Marmon car was beautifully proportioned, and had an alloy engine. The list price of the Marmon car was $4.925; there was a companion Marmon 8-125 in 1932, but only the Marmon Sixteen was listed for 1933. At the very end Marmon was testing a Marmon car with a 150bhp V12 with independent front suspension, De Dion rear axle, and tubular backbone frame, but this never saw production.
