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.

The first Riley car was a small single-cylinder belt-driven voiturette which Riley car did not go into production. Motor Riley tricycles followed n 1900, and a handlebar-steered Riley tricar with 2 forward speeds, and a 517cc engine with mechanically-operated inlet valves in 1903. Riley Tricars were made until 1907, later examples of these threewheeled Riley cars being twins with driver’s seats in place of saddles, water cooling and wheel steering. The 1.034cc V-twin engine was also fitted to the Riley car company’s first 4-wheelers, which Riley car had amidships-mounted power unit with their gearboxes alongside and chain drive, and the Riley car sold for £168. Bigger V-twins of 2-litres’ capacity, more conventional layout and round radiators were made from 1908 onwards. These Riley car incorporated pressure lubrication, shaft drive, constant-mesh 3-speed gearboxes, and Riley’s own patent detachable wheels, the demand for which brought Riley car production almost to a standstill and was responsible for the formation of the new Riley car company in 1912. In 1914 the 2-cylinder Riley cars were still being made, but there was also a new 2.9-litre sv monobloc four Riley car with worm drive, which was offered again after World War 1 by the Riley engine Co, though this Riley car soon disappeared from the market.
The first post-war 1 Riley cars were the Riley Elevens with sv 1½-litre 35bhp engines, alloy pistons and full electrical equipment which Riley cars were selling £550 in 1920, acquiring spiral bevel final drive in 1921. The Redwinger sports version of the Riley car, with wire wheels and polished-aluminium coachwork appeared in 1923, offering 70mph for £450, and the sv Riley cars were continued until 1928, with a 1.645cc engine and the option of front-wheel brakes in 1925. One of these Riley Twelves was used to prospect Kenya’s road system in 1926, and in 1927 there was even a supercharged development Riley car of the Redwinger available, though this Riley car was overshadowed by Percy Riley’s advanded new Riley Nine, with a 1.987cc 32bhp 4-cylinder engine, twin camshafts and high push-rods, a unit which was to form the basis of all Riley car designs made up to 1957.
In 1928 came the handsome Riley Monaco fabric sports saloon version at £298, a best-seller Riley car from the start, and the lowered and tuned Riley Brooklands sports, inspired by the late J.G. Parry Thomas, which Riley car weighed 1.120lb, had a twin-carburettor 50bhp engine, and was capable of 80mph, all for £395. A twin carburettor variant of the touring Riley Nine followed in 1929, along with a new 1.6-litre 6-cylinder Riley Fourteen of similar styling at £495.
Riley cars had a distinguished competition record in the following years: class wins with a Riley car in the 1929, 1930, and 1931 Tourist Trophies were followed by Whitcroft’s outright victory in 1932, while two more wins were recorded by F.W. Dixon on the later 1½-litre 4-cylinder Riley car in 1935 and 1936. A 4th place at Le Mans in 1933 led to 2nd, 3rd, 5th, 6th, 12th and 13th places in 1934, not to mention three successive wins – 1934, 1935, and 1936 – in the BRDC 500 Mile Race at Brooklands. Leverett won the light-car class of the 1931 Monte Carlo Rally on a Riley Nine, while the 6-cylinder racing Riley cars of 1933-1934 formed the genesis of the ERA, and nearly twenty years later the late Mike Hawthorn was to make his name in Club Racing on sports Riley Nines and 1½-litres. Both the Riley Nine and the Riley 14/6 were progressively developed, the former Riley car acquiring vacuum feed in 1931, a lowered chassis and semi-panelled bodywork in 1932, and an optional (later standard) preselector gearbox in 1934. A super-sports 6-cylinder 1½-litre Riley car with water-cooled centre main bearing appeared in 1932, being followed in 1933 by the touring Riley Mentone version at £348. 1933 also brought two advanced body styles of Riley cars, the fastback Riley Kestrel saloon (listed up to the end of the old Riley car company in 1938) and the more-conservatively styled Riley Falcon on which the doors opened into the roof. A Salerni automatic transmission was offered on the 14/6 Riley car, but did not go into regular production.
Two handsome sports two-seater variants Riley cars were listed in 1934/ 1935, the Riley 9hp Imp on a 7ft 6in wheelbase and the 1.654cc 6-cylinder Riley MPH which gave over 90mph for £550, while a newcomer in 1935 was the classic 1½-litre Four Riley car with Wilson gearbox, rod-operated Girling brakes and centralized chassis lubrication, a best-seller in its class at £335, and available in single- and twin-carburettor versions: subsequent developments were the 85mph Riley Sprite two-seater and the Riley Kestrel-Sprite and Riley Lynx-sprite saloon and tourer which offered more room but the same highly-tuned engine for £398. A cheaper Riley Nine, the Riley Merlin with pressed-steel bodywork, came on the market in 1936, along with the 1½-litre, a 6-cylinder 15/6 Riley car, and a 2.2-litre V8 Riley car, of which very few were made, the engine of the V8 Riley car made up of two 9hp blocks. 1937 Riley Nines came with new 6-light Riley Monaco bodies and twin-carburettor 42bhp engines as standard, while other new models of Riley cars were an abortive 3-litre luxury V8 made by a subsidiary company, Autovia Cars, and a more successful long-stroke 2.4-litre Big Four Riley car on classic lines, with an 85bhp engine and Borg-Warner 3-speed synchromesh gearbox incorporating an overdrive at £385. Overdrive was optional on 1938 1½-litres Riley cars.
Finances, however, were insecure and the Riley car company were acquired by the Nuffield Organization later in that year. Under the new management only the 1½-litre and the Big Four Riley cars were continued, with disc wheels, conventional synchromesh gearboxes and Wolseley-like bodywork. The post-World War 2 successors Riley cars used the same engines, but were altogether more handsome Riley cars with independent torsion-bar front suspension and fabric tops, the bigger engine’s output being boosted first to 90bhp and then to 100bhp: this Riley car unit was also used by Healey in the 1946 – 1954 period, while some open three-seater versions with column change were made by Riley cars for export. Hypoid back axles and full hydraulic brakes were incorporated in 1952 Riley cars.
After the Nuffield-Austin amalgamation the 1½-litre Riley car was continued into 1955 with relatively little change, but the 1954 2½-litre Riley Pathfinder shared its bodywork with Wolseley’s 6-90, the new chassis being a BMC design with coil rear suspension and cam-type steering. Even this disappeared after 1957 in favour of a version with a 2.6-litre 6-cylinder ohv BMC engine, and subsequent Riley cars were merely luxury versions of BMC themes, starting with the Riley One-Point-Five (basically a Wolseley 1500), and working through variations of the Farina-styled 1½-litre and 1.6-litre saloon Riley cars, the Mini, and, from 1966, the 1100/1300 family with Hydrolastic suspension, known in Riley cars guise as the Kestrel. Riley’s Mini, the Riley Elf, had a built-out boot and (from 1963) a 998cc engine in place of the standard 848cc Austin/ Morris type. This meaningeless badge-engineering was stopped by British Leyland in 1969.
