David Buick’s first car followed conventional American design in having a flat-twin engine mounted amidships under the floor, a two-speed planetary transmission, and final drive by chain – but unusual were its mechanically-operated full overhead valves, a feature of all cars bearing the name of Buick to the present day, apart from Buick fours of the 1906 – 1909 period, which had side-valves in T-heads. Capacity was 2.6-litres, and it sold for $1.250. Developments of this original Buick model were selling in England for £294 in 1907, but there was already a companion 4.2-litre four with front-mounted engine, and 1908 saw a ‘square’ Buick four (95.2x95.2mm) with planetary transmission added to the range. In 1908 W.C. Durant formed General Motors, Buick being one of the original members of the group. In 1909 Bob Burman drove a Buick to victory in the first race ever held at Indianapolis Speedway. Sales had exceeded 30.000 Buick cars by 1910. For the next few years Buicks with English bodywork were sold in Britain first as ‘all British Bedfords’, and then as ‘Bedford-Buicks’. By 1912 planetary transmission had been dropped and 4-cylinder Buick cars were available in 2.7-litre, 3.3-litre and 5.2-litre sizes, still with rhd, but with the brake and gear levers faired into the driver’s door. Delco electric lighting and starting were standard on all Buick models by 1914, in which year Buick marketed their first six, the Buick B-55. Nearly 126.000 Buick cars were sold in 1916, and the company entered the post-World War 1 era with a 2.8-litre four and a 3.9-litre six, cars which brought Buick into fourth position in US sales, behind Ford, Dodge, and Chevrolet, all far cheaper vehicles; a Buick Six tourer cost $1795 in 1921.

Drastic change came in 1924. The Buick cars acquired front wheel brakes as standard equipment, while cylinder heads were now detachable, and the rounded radiator shell gave way to an angular, Packard-like outline that was to continue until 1928. Prices of Buick fours started at $935, and the cheapest Buick six was listed at $1565. The 6-cylinder cars became the staple in 1925 and the ‘back-to-front’ gear shift pattern shared with Dodge was discarded in 1927. The Buick cars were completely re-styled in 1929, when hydraulic shock absorbers were added, and the capacities of the two basic Buick models were increased to 3.8-litres and 5.1-litres respectively. Prices ran from $1.195 to $2.145, but for Buick customers with slenderer pockets there was the Buick Marquette. Buick went over to an all-straight-8 programme, still with overhead valves, in 1931. Expanding brakes were now standard at front and rear. Synchromesh was standardized on the more expensive Buick models and available as an extra on all, and was standardized throughout the range in 1932.

Buick’s evolution up to World War 2 followed General motors policy; cruciform-braced frame and no-draught ventilation in 1933, Dubonnet-type ifs in 1934, and turret-top styling, down-draught carburation and hydraulic brakes in 1936 with the Buick DA-series – one example of which became famous when it took Mrs Ernest Simpson into exile at the time of the British Abdication crisis. Despite Buick’s upper middle-class position in the GM sales picture, the 1937 range of 4.1-litre and 5.2-litre eights covered everything from a sedan on a 10ft 2in wheelbase at $855 up to a seven-seater Buick C090 limousine at $2095; prices in Britain, where the Buick cars were consistently well received between the Wars, were £500 and £865 respectively. 1938 Buicks had coil springing all round, and that year the Division produced GM’s first ‘dream car’, a two-seater convertible coupé styled by Harley Earl on a Roadmaster chassis. Buicks used the same engines up to 1952, though they came out with a 2-speed Dynaflow automatic transmission in 1948. In 1948 they pioneered the now popular hardtop convertible body with their Buick Riveira. The smaller engines were, however, enlarged to 4.3-litres in 1952, and the following year the Division’s first ohv V8 unit appeared; its capacity was 5.3-litres, and its output 188bhp. All 1954 Buicks used this type of engine.

Buick sales dropped in 1958, but the 1959 cars were style leaders with the delta tail and fins. Buick’s first effort at a compact car in 1961 was the Buick Special with an all-aluminium 155bhp, 3½-litres V8 engine, replaced the following year by a cast-iron V6, used also by Oldsmobile. The demand for cars with a sporting flavor resulted in the handsome Buick Riviera sports coupé of 1963, which by 1966 was giving 340bhp from 7 litres, and was capable of 120mph. Automatic transmission was, of course, standard. The 1966 Buick range had a more sporting atmosphere than in the past, and embraced the Buick Special with a 9ft 7in wheelbase and a choice of V6 or 4.9-litre V8 engines; the Buick Skylark with the same chassis dimensions and a 6.6-litre V8 engine; and the bigger Buicks in the shape of the 5½-litre Buick Le Sabre, the 6.6-litre Buick Wildcat, the Buick Electra, and the top-line Buick Riviera. These models continued without basic change until 1971, though concealed screenwipers (found on other GM cars of that year) and the option of front disc brakes came in 1967, and cylinder capacities were increased: the biggest V8 ran to 7046cc in that year, to 7456cc in 1970. The small 3½-litre V8 abandoned by Buick in 1963 was taken up by Rover of England in 1968 and was subsequently supplied by them to Morgan. The 1971 Buick station wagons featured glide-away tailgates. By 1972 all but the economy Buick Skylarks had front disc brakes as regular equipment. Engine outputs were reduced (from 370bhp to 250bhp in the case of the most potent V8), and the Buick Riviera was restyled in the Chevrolet Corvette hardtop idiom. Only V8s, of 5736cc and 7456cc, were offered in 1973; the Buick Skylark gave way to a new car with an old Buick name, the Century, that reverted to the single-headlamp layout.

Cadillac

US, 1903 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.
