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.

DeSoto

US, 1913 – 1916

DeSoto Motro Car Co, Auburn, Ind.

The DeSoto appears to have succeeded the Zimmerman. This was a large car with a 55hp, 6-cylinder engine, which was furnished with a compressed-air starter. The DeSoto model Six-55 five-seater touring car sold for $2185.

US, 1928 – 1960

Chrysler Motors Corp, Detroit, Mich.

The DeSoto was launched in 1928 as a 3.2-litre side valve six to compete with Oldsmobile, Pontiac and the cheaper Nashes. Styling and general design of the DeSoto were in line with the 1929 Chryslers, and at $885 for a DeSoto sedan 90.000 were sold in the first twelve months. A 3.4-litre straight-8 DeSoto on a 9ft 6in wheelbase was announced for 1930 as the world’s cheapest 8-cylinder car. However, DeSoto suffered badly in the Depression, and in 1932, when flexible rubber engine mountings and free wheels were made available, sales dropped to 26.000 DeSoto cars.
The DeSoto disappeared from the British market about this time, though certain ‘Chrysler’ models listed in England (the Mortlake, Croydon, and some of the Richmonds) were in fact DeSoto cars in all but name. A 6-cylinder version of Chrysler’s advanced unitary-construction Airflow, the SE-type with a 4-litre engine, was brought out in 1934, but was an unsuccessful as its bigger sister. Later DeSotos followed regular Chrysler lines closely though in later years there was a tendency for DeSoto to move into a higher price class than Dodge; by 1952 DeSotos started $300 higher than the companion make.
By 1939 the DeSoto cars for sale were being made with independent front suspension, hypoid back axles and column change. There was a choice at DeSoto of two 6-cylinder engines and three wheelbase lengths, the longest of these being reserved for seven-seater bodywork – DeSoto continued to offer a really roomy family car right up to 1954. A 4-speed semi-automatic Vacumatic transmission became an option in 1941, but DeSoto’s big post-war change of models did not take place until 1952, when the division followed Chrysler’s lead in adopting the oversquare ohv V8; the DeSoto version was of 4½-litre capcity and developed 16-bhp. With the advent of Chrysler’s ‘flight sweep’ styling in 1955, the side-valve sixes were dropped and the standard engine in a DeSoto was now a 4.8-litre eight, giving 185bhp in Firedome guise, and 200bhp in Fireflite form. Though this redesigning saved Chrysler sales generally, the slump in the medium-price class had an adverse effect on DeSoto and in 1959 the DeSoto division was merged with Plymouth. Last of the DeSotos were the 1961 models, unitary-construction cars with a choice of three engines: Plymouth’s 145bhp ohv ‘slant six’ as used in the Valiant, and V8s of 230 and 265bhp, the two former only in Canadian DeSotos. Production of DeSoto cars ceased in November 1960 after only a few had been delivered.
