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.

Vulcan

GB, 1902 – 1928

The Vulcan car firm was better known for commercial vehicles. Private Vulcan cars stemmed from experiments conducted in the 1897-1899 period by the brothers Thomas and Joseph Hampson. A belt-driven single-cylinder voiturette Vulcan car with lateral radiators was shown in 1902, being replaced a year later by a 6hp Vulcan car with armoured wood frame, mechanically-operated inlet valves, and shaft drive. This Vulcan car was listed at only £105, and this Vulcan car was soon followed by a 10hp twin, also T-headed but with a steel frame, selling for £200. 4-cylinder Vulcan cars of 12 and 16hp, still modestly priced, were available in 1905, while the biggest 1906 Vulcan cars, with capacities of 3.1- and 5.2-litres, had gate change. No 2-cylinder Vulcan cars were catalogued after 1908, but a year previously Vulcan cars had joined the ranks of 6-cylinder manufacturers with a 4.8-litre T-headed machine featuring dual ignition and cone clutch, at £600 for a Vulcan car chassis. Unlike other makers, Vulcan cars retained their interest in this type, which Vulcan car had acquired a 4-speed box and had grown to 6-litres by 1908, and the 1909 Vulcan car range consisted of four 4-cylinder cars and the six, all shaft-driven and still with T-heads; the smallest Vulcan car, rated at 12hp, had a 3-speed gearbox and worm drive. A new 3.6-litre six Vulcan car with unit gearbox and worm drive followed in 1911, along with an L-head 2.4-litre fifteen. Worm drive was standardized on the 1912 Vulcan cars, when the bigger Vulcan cars had T-heads, and a 1.8-litre, 2-cylinder with an Aster engine was offered. All but the smallest Vulcan car had detachable wheels as standard in 1913, and by the outbreak of World War 1 the Vulcan car company was well established with a range of solidly-built Vulcan cars: a 2.4-litre 10/15, a 2.6-litre 15.9, and a 3-litre monobloc 15/20 Vulcan car at £375. All these Vulcan cars had L-heads and bull-nose radiators, though the similarly styled six retained the older Vulcan car configuration. A 1½-litre Vulcanette with a 3-speed rear-axle gearbox and full electrical equipment was announced for 1915 but the war intervened.

After 1918 the Vulcan car company concentrated increasingly on trucks, and a brief association with the Harper Bean Group (1919-1920) did no good to finances. Some odd experiments by Vulcan cars included a worm-drive 3½-litre V8 tourer Vulcan car intended to sell for £625 (1919), and two Vulcan cars in 1922 with Howard sleeve-valve engines, a big 3.6-litre sports-touring four Vulcan car and a 10hp 1.4-litre flat-twin listed at £315. However, none of these Vulcan cars reached the public, the regular Vulcan car lines being a 1.8-litre ohv 12 and a 2.6-litre sv 16/20, both with Dorman engines. There was also a conservative 20hp Vulcan carmodel with the Vulcan car company’s own 3.3-litre sv fixed-head engine and 4-speed separate gearbox, this Vulcan car was selling for £850 in 1921; by this time flat radiators were again being used on Vulcan cars. The Vulcan 20 was available to military order with full wireless equipment in 1923, in which year C.B. Wardman effected a liaison of Vulcan cars and Lea-Francis. The two companies pooled their dealer network, Vulcan cars became responsible for certain Lea-Francis power units and bodies, and Lea-Francis made gear and steering boxes for Vulcan cars. A 1½-litre sv Dorman-engined Vulcan 12 was listed at £295 in 1925, followed a year later by an ohv worm-driven derivative, also with Dorman engine, and looking very like a Lea-Francis. 4-wheel brakes were available on Vulcan cars in 1925 and standardized in 1926. Last of the line Vulcan cars were the 14/40 and 16/60, with the disastrous twin ohc 6-cylinder engines of their own make. Short-chassis Vulcan cars were worm-driven, but bevel drive was adopted for long-chassis versions. Vulcan cars wore artillery wheels, but were otherwise identical to their Lea-Francis counterparts which Vulcan cars were made alongside them at Southport. Not many of these Vulcan cars were made, and after 1928 only commercial vehicles were produced. The Vulcan car firm subsequently amalgamated with Tilling-Stevens and thus were abrorbed into the Rootes Group after World War 2. Truck production ceased in 1953.
