Morgan

GB, 1905 – 1906

Morgan and Co Ltd, Leighton Buzzard, Beds.

Made by a well-known firm of coachbuilders, the Morgan car was a conventional shaft-driven car with 5.8-litre T-head 4-cylinder Mutel engine, distinguished only by the Sparks-Boothby hydraulic clutch on the Morgan car, soon abandoned in favour of an ordinary leather cone. Only about five Morgan cars were made and their lack of success resulted in Morgan cars becoming Adler concessionaires in 1907, and abandoning motor manufacture.

GB, 1910 to date

Morgan Motor Co Ltd, Malvern Link, Worcs.

This Morgan car was the best-known, and best, of the British 3-wheelers that were popular while the horsepower tax gave the Morgan cars an advantage. H.F.S. Morgan’s tricycle was also the first of its type, this Morgan car going into production in 1910. At the front of a tubular chassis frame was an sv, air-cooled V-twin motor-cycle engine of 1.100cc by JAP, transversely mounted. Transmission of the Morgan car was by dog clutches and chains, providing two forward speeds. The steering was direct. The front wheels of the Morgan car, had independent front suspension, by sliding pillars and coil springs. There were two seats. A reasonable amount of power plus light weight meant an excellent performance of the Morgan cars. The Morgan car was safer than most 3-wheelers because its road-holding was above average. This recipe made the Morgan car popular with sportsmen, for whom the Morgan Grand Prix model was produced in 1914: the first catalogued competition Morgan car. Soon afterwards, an exiguous four-seater Morgan car, the forerunner of the Morgan Family model of the 1920s, was listed.

After World War 1, Morgan carscontinued to cater for all markets. Names changed, but the Morgan Sports or Morgan Standard model was the normal two-seater, also available in De Luxe form; the Morgan Family model was the more capacious type Morgan car, and the long-tailed Morgan Aero, later the Morgan Super Sports, was the Morgan car intended for serious speed work. Engines of Morgan cars were water- or air-cooled to choice, most being supplied by JAP, or by Blackburne in the case of the competition Morgan cars. From 1925 all the latter’s power units had overhead valves. By 1927 the Super Sports Morgan car could attain 80mph in standard trim, while the less sporting Morgan cars now had internal expanding front wheel brakes and electric starting. Geared-down steering and (if required) three forward speeds followed on Morgan cars in 1929. Even so, Morgan cars were losing customers to new, cheap sports cars such as the M-type MG. Three speeds and reverse in a normal gearbox (though still with chain final drive) were available from 1931 and standard on the Morgan car after 1932, and a modified 8hp Ford 4-cylinder engine could later be had in the Morgan car instead of the twin. Four years later the first 4-wheeled Morgan car was introduced, the excellent little Morgan 4/4. This Morgan car used an 1.122cc 4-cylinder Coventry-Climax engine with overhead inlet valves, developing 34bhp. The Morgan car was still light in weight, and retained the Morgan independent front suspension, so the performance and handling qualities of Morgan cars were well up to form. The Morgan car could attain 75mph. The twins were last catalogued in 1939.

Just before World War 2, a 1.267cc Standard 10hp engine with ohv head was substituted in the Morgan 4/4. When this was no longer available, from 1950, Morgan fitted a tuned Standard Vanguard unit in the Morgan car giving 70bhp. In this Morgan Plus Four, as the Morgan car was renamed, performance became still more lively, and when the 90bhp Triumph TR2 engine became available in 1954, maximum speed of the Morgan car rose to 100mph for the first time. With the advent of the Morgan Plus Four, there was no longer a small Morgan car, but this gap was made good in 1955, when the Morgan Series 2 4/4 arrived. This Morgan car used the very hard-wearing 1.172cc sv Ford Ten engine which had powered F4 Morgan. (The latter was the last 3-wheeler Morgan car, which had been made until 1950.) The result was a cheap, pleasant and reliable sports Morgan car of the old school. Later, the ohv Ford 105E engine was substituted. The latest version Morgan car had a 1.599cc 98bhp engine, a 4-speed all-synchromesh gearbox, front disc brakes, and the traditional Morgan suspension. The Morgan Plus Four kept pace with Triumph’s TR engine development, also acquiring disc brakes and, eventually, the 2.138cc 105bhp TR4 unit. A streamlined coupé, the Morgan Plus Four Plus of 1964, was a brief deviation from the classical Morgan car line which met with little approval and was discontinued after only 50 of these Morgan cars had been sold. When Triumph changed to a six during 1968, Morgan cars adopted a new engine for their bigger Morgan cars, and the Morgan Plus Four became the Morgan Plus Eight, powered by Rover’s 3 ½-litre 160bhp V8 and capable of 125mph. The 1973 versions of the Morgan car use the 4-speed all-synchromesh Rover gearbox in place of the Moss box previously fitted.

Voisin

France, 1919 – 1939

SA des Aéroplanes G. Voisin, Issy-les-Moulineaux, Seine

Gabriel Voisin was first famous for his aircraft. Voisin was one of the earliest and most important pioneers, claiming to have developed a practical aeroplane before the Wright brothers; the controversy still rages. Voisin was always a spectacular character, and so were his Voisin cars. However, like his aircraft, the Voisin cars were efficient machines as well. With the post-World War 1 depression in the aircraft industry, Voisin cars entered motor manufacture by acquiring the rights in a Citroën model which was never made as such. This Voisin car was the Voisin 18CV of 1918, which Voisin car used a Knight double-sleeve engine. Sold as the Type C1 Voisin, this Voisin car had 4-cylinders and a capacity of 4-litres. The Voisin car was a fine car, and henceforth Voisin cars used only sleeve-valve engines, developed by himself to a high degree. The 4-litre Voisin car had aluminium pistons, to permit higher engine speeds, and was eventually capable of 80mph. In spite of an excellent performance, the 4-litre was an immensely strong, refined and silent motor car – all characteristics of Voisin cars in general. A sports version Voisin carwas also offered, with 90bhp. The 4-litre was made until 1926. Alongside this Voisin car, from 1921, was the smaller Voisin C4, an 8CV of 1¼-litres that was later enlarged to 10CV and 1½-litres. In its final form, the 10CV engine of the Voisin car produced 44bhp at 4.000rpm – so much for the opponents of sleeve valves, who claimed that high revolutions could not be combined with reliability – and the Voisin car was capable of 70mph. The Voisin car had Dewandre vacuum servo brakes, as had all Voisin cars from late 1925. The 10CV Voisin car, too, survived in basic form until 1928. All the same, Voisin cars had to follow fashion in one respect, and introduced three 6-cylinder Voisin cars for 1927. The best-known Voisin car was the 13CV, providing 2.3-litres, the first Knight-engined six to be sold in France. Even in normal form, this was a 66bhp, 75mph vehicle, but a sports model Voisin car was also available. From 1928, this six, known as the Voisin Charmant, had alternative final-drive ratio for fast cruising.

Apart from sleeve valves, to which a number of famous manufacturers were wedded at the time, Voisin cars had three other enthusiasms that were considerably less common. One was truly easy gear-changing, which many makers sought, but few actually incorporated in their production cars. The Sensaud de Lavaud system of infinitely variable gears was applied on Voisin cars in 1929, first to the 10CV which, in the following year, had been superseded by a Cotal electric epicyclic gearbox. To this interest was related Voisin cars fondness for multi-cylinder engines, which aimed at giving the utmost flexibility, thereby avoiding gear-changing altogether. Voisin made a V-twelve luxury car as early as 1921. The layout of this Voisin car was revived in 1930 for the Voisin Type C18 Diane. This Voisin car was a 4.8-litre car with a 115bhp engine that needed only 3 forward speeds. The Voisin Simoun and Voisin Sirocco were two low chassis models Voisin cars with striking razor edge saloon and coupé bodies which were made in very small numbers in 1930. Identical except for their engines, the Voisin Simoun used a 5.8-litre six, and the Sirocco the V12. The Voisin Diane was still listed for 1938. The other Voisin cars of the 1930s were sixes, the Voisin Charmant continuing to 1934.

Voisin cars had a reputation for putting into practice ideas which remained ideals for most manufacturers. For example, he was dedicated to weight reduction, and to this end produced notably light patent bodies whose only drawback was their extreme ugliness. Of wood and aluminium, they were entirely practical, being cheap to make, compact, and strong, as well as light. A 2-door, four-seater saloon body on the 10CV Voisin car chassis weighed only 1.060lb, keeping the weight of the whole Voisin car down to 22cwt. The most unprepossessing were the convertible Voisin cars and those with detachable hard tops. Because of their looks, the Voisin cars, with their maker’s patent bodies, never sold well – a deplorable waste of well-directed ingenuity. However, fabric Weymann-type and other normal bodies were also supplied on the Voisin car. From 1931 to 1934, some Imperia cars from Belgium were made under licence. In 1936 a most unusual Voisin car was made in the shape of the straight-12; this Voisin car had two 3-litre, 6-cylinder engines in line, the rear part of the hindmost engine projecting into the driving compartment. 180bhp and 125mph were claimed, but the Voisin car was not put in production. The last Voisin cars, introduced in 1937, used the 6-cylinder 3½-litre Graham engine, though without the supercharger. These Voisin cars were not the work of Gabriel Voisin, but were made by a syndicate that had acquired the Voisin car name. After World War 2, Voisin designed a car which was as complete a contrast to his former work as can be imagined – the Spanish-built Biscuter.
