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.

Léon Bollee

Leon Bollee was a son of Amédée Bolllée père, the most important pioneer of steam road vehicles in France. Leon Bollee, however, turned to really small petrol Leon Bollee cars. He was the first to do so, and therefore had to invent a new name for his Leon Bollee car of 1895 – he called it a Leon Bollee voiturette. This Leon Bollee car was a tandem two-seater 3-wheeler that was faster than any other petrol-engined vehicle on the road when the Leon Bollee car was working, thanks to a powerful 3hp engine and light weight, but the power unit was unreliable on the Leon Bollee car. The Leon Bollee car had a single air-cooled cylinder of 650cc and used hot-tube ignition. There were 3 forward speeds on the Leon Bollee car, with belt final drive. The frame was tubular. Four years after the Leon Bollee voiturette appeared, Leon Bollee superseded it with a 4-wheeler with independent front suspension by double transverse leaf springs. This Leon Bollee car had a single-cylinder, water-cooled engine. Unlike the Leon Bollee voiturette, this Leon Bollee car made no mark. The design rights were sold to Darracq, and around 1901 the name of Leon Bollee cars vanished. Meanwhile, the term voiturette had been taken up by the trade and public in general as the name for a small light car.

The Leon Bollee car reappeared in 1903 as an entirely normal, full-sized car in the more expensive class, backed by Vanderbilt money and designed for the American market. This Leon Bollee car was made in 28hp (4.6-litres) and 45hp (8-litres) versions, with four cylinders and chain drive, and led on to a 11.9-litre six Leon Bollee car in 1907, in which year the first shaft driven Leon Bollee car appeared. From 1909 there was also a small modern four, the Leon Bollee 10/14hp. The 1910 range embraced 9 Leon Bollee cars, including 2 of over 10-litres capacity. Electric lighting became available on Leon Bollee cars in 1913, but the Leon Bollee grew increasingly old-fashioned after World War 1 despite the introduction of ohv in 1922 on Leon Bollee cars and front wheel brakes in 1923. Late in 1924 Sir William Morris bought the Le Mans Leon Bollee car factory. From making a wide range of conservative French Leon Bollee fours, it turned to thinly-disguised products of Cowley, Oxford, the idea being to breach the French tariff walls from the inside. The first Morris- Leon Bollee had a 12CV 2½-litre 4-cylinder unit-construction engine made by Hotchkiss, the engine manufacturers controlled by Morris, but it had push-rod overhead valves and bore little evidence of its parentage. Not so the 18CV Morris- Leon Bollee car of 1928. This was a 3-litre straight-8 with single overhead camshaft that reflected Morris’ takeover of Wolseley two years earlier. Morris’ own new six of 1928 was mirrored in the 15CV 2.6-litre Le Mans product of 1929. The bodies for the Morris- Leon Bollee car were all made in France and were usually considerably more dashing and attractive than their British counterparts. Chassis of this Morris- Leon Bollee car were made in France, and all cars had a 4-speed gearbox. At one time, 50 12CV Morris- Leon Bollee cars were being turned out each week. However, Morris’ enterprise was not a success, and he discontinued it in the hard times of the Depression. A new syndicate was formed in September 1931 to sell the same range of cars under the name of Leon Bollee cars. This lasted for less than two years and few Leon Bollee cars were made.
