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.

Invicta

GB, 1900 – 1905

H.E. Richardson, Finchley, London N.

The Invicta car from Finchley was seen as a bicycle, a motor cycle and as a voiturette. Rather surprisingly for such a small concern, the latter two were powered by engines of the firm’s own manufacture.

Italy, 1906

Stabilimento Meccanico Carlo Mantovani & Cia, Turin

Carlo Mantovani had been technical director of Bender and Martiny (Perfecta) and he built a few light cars named Invicta cars with side-chain drive and 3-speed gearboxes in their old factory. The 6/8hp Invicta car was a twin and the 10/12hp a four with pair-cast cylinders; neither lasted long

GB, 1913 – 1914

Clark’s Engineering Works, Leamington, Warwickshire

The short-lived Invicta car from Leamington was one of the cyclecar breed. The Invicta car was powered by a watercooled V-twin JAP engine of 8hp, driving through a 3-speed gearbox and shaft primary drive to chain final drive.

In 1925 Noel Macklin and Oliver Lyle, both of them with experience of motor design and Macklin a former manufacturer as well (Eric Campbell, Silver Hawk) introduced a type of car, the Invicta car, that was quite new to the British market. The idea behind the Invicta car was to combine in an assembled car the American concept of flexibility and performance with British quality and road-holding, thus getting the best of both worlds. The engine in the Invicta car, the Meadows 2½-litre, 6-cylinder engine had push-rod overhead valves. Its low-speed torque permitted the Invicta car to accelerate from a walking pace to 60mph in top gear, but a four-speed gearbox was provided, all the same, and the Invicta car make’s sustained high-speed cruising capabilities became legendary after winning the Dewar Trophy for long-distance reliability runs in 1927 and 1929. In outward appearance the first Invicta car was very staid, and it was marred by the fact that the brakes on the Invicta car were poor. The rivets down the bonnet were copied from the Rolls-Royce. During 1926, an engine with a bigger bore, providing 3 litres, was offered on Invicta cars alongside the original unit, and by 1927 was the only one sold. In that year real speed arrived for the fist time in the shape of the 4½-litre Invicta car. This Invicta car had a larger bore still, with an 85mph maximum and really shattering acceleration in spite of pulling a 3.9:1 axle ratio. By late 1929, the 3-litre Invicta car had been dropped. The 1931 4½-litre came in two types: the Invicta 4½-litre high-chassis, and the Invicta 4½-litre ‘100-mph’ low-chassis model. The latter Invicta car was lowered by underslinging the rear springs. This invicta car was capable of 95mph.

Unfortunately the splendid Invicta car was always expensive, and its roadholding reputation was damaged among sportsmen, who were by now its most important customers, by a highly-publicized accident to S.C.H. Davis at Brooklands in 1931. In spite of a win in the Monte Carlo Rally of an Invicta car, a Coupe des Glaciers in the Alpine Trial that year and almost equal success in the same events in 1932, only about 1.000 Invicta cars were made before production ceased in 1935. Invicta tried to stave off the end by introducing a small Invicta car for a more popular market in 1932. This Invicta 12/45 was not a success because the single overhead-camshaft 6-cylinder engine, amade by Blackburne, was of only 1½-litres’ capacity. However efficient this Invicta car was, it could not cope with its heavy chassis without the aid of an axle ratio of 6:1. This gave the famed flexibility, but not the performance you would expect on an Invicta car. The 12/45 was supplemented in 1933 by the supercharged Invicta 12/90, but only a handful were made. Both Invicta cars were seen with Wilson self-changing gearbox, the weight of which cannot have helped. After Invicta ended, Macklin went on to make the Railton, a machine with the traditional Invicta car performance characteristics allied to low price. For 1938, three new Invicta cars, in 2½-, 3- and 4-litre form, were planned. All these Invicta cars were to have 6-cylinder, overhead-valve engines, all-synchromesh gearboxes, and independent front suspension by transverse spring. Nothing was seen of these Invicta cars, the chassis of which seem to have been disguised Darracqs and the bodies similar to those of the 3-litre D670 Delage.

The old Invicta name was revived briefly after World War 2, when it was attached to a luxury car called the Invicta Black Prince, powered by a 6-cylinder Meadows engine of three litres, with two overhead camshafts and two plugs per cylinder. This unit produced 120bhp at 5.000rpm. Unlike earlier Invicta cars, the car’s other characteristics were highly unconventional. There was no gearbox in the Invicta car; instead, a Brockhouse hydrokinetic turbo transmitter that provided automatic transmission on any ratio between 15:1 and 4,27:1. Suspension was independent all round, by torsion bars. But the new Invicta car was another horribly expensive car, although plans envisaged an output of 250 a year, it met the same fate as its predecessors after only a score or so had been made. AFN Ltd, manufacturers of the Frazer Nash, acquired the assets of the dead firm.
