Leon Bollee was a son of Amédée Bolllée père, the most important pioneer of steam road vehicles in France. Leon Bollee, however, turned to really small petrol Leon Bollee cars. He was the first to do so, and therefore had to invent a new name for his Leon Bollee car of 1895 – he called it a Leon Bollee voiturette. This Leon Bollee car was a tandem two-seater 3-wheeler that was faster than any other petrol-engined vehicle on the road when the Leon Bollee car was working, thanks to a powerful 3hp engine and light weight, but the power unit was unreliable on the Leon Bollee car. The Leon Bollee car had a single air-cooled cylinder of 650cc and used hot-tube ignition. There were 3 forward speeds on the Leon Bollee car, with belt final drive. The frame was tubular. Four years after the Leon Bollee voiturette appeared, Leon Bollee superseded it with a 4-wheeler with independent front suspension by double transverse leaf springs. This Leon Bollee car had a single-cylinder, water-cooled engine. Unlike the Leon Bollee voiturette, this Leon Bollee car made no mark. The design rights were sold to Darracq, and around 1901 the name of Leon Bollee cars vanished. Meanwhile, the term voiturette had been taken up by the trade and public in general as the name for a small light car.

The Leon Bollee car reappeared in 1903 as an entirely normal, full-sized car in the more expensive class, backed by Vanderbilt money and designed for the American market. This Leon Bollee car was made in 28hp (4.6-litres) and 45hp (8-litres) versions, with four cylinders and chain drive, and led on to a 11.9-litre six Leon Bollee car in 1907, in which year the first shaft driven Leon Bollee car appeared. From 1909 there was also a small modern four, the Leon Bollee 10/14hp. The 1910 range embraced 9 Leon Bollee cars, including 2 of over 10-litres capacity. Electric lighting became available on Leon Bollee cars in 1913, but the Leon Bollee grew increasingly old-fashioned after World War 1 despite the introduction of ohv in 1922 on Leon Bollee cars and front wheel brakes in 1923. Late in 1924 Sir William Morris bought the Le Mans Leon Bollee car factory. From making a wide range of conservative French Leon Bollee fours, it turned to thinly-disguised products of Cowley, Oxford, the idea being to breach the French tariff walls from the inside. The first Morris- Leon Bollee had a 12CV 2½-litre 4-cylinder unit-construction engine made by Hotchkiss, the engine manufacturers controlled by Morris, but it had push-rod overhead valves and bore little evidence of its parentage. Not so the 18CV Morris- Leon Bollee car of 1928. This was a 3-litre straight-8 with single overhead camshaft that reflected Morris’ takeover of Wolseley two years earlier. Morris’ own new six of 1928 was mirrored in the 15CV 2.6-litre Le Mans product of 1929. The bodies for the Morris- Leon Bollee car were all made in France and were usually considerably more dashing and attractive than their British counterparts. Chassis of this Morris- Leon Bollee car were made in France, and all cars had a 4-speed gearbox. At one time, 50 12CV Morris- Leon Bollee cars were being turned out each week. However, Morris’ enterprise was not a success, and he discontinued it in the hard times of the Depression. A new syndicate was formed in September 1931 to sell the same range of cars under the name of Leon Bollee cars. This lasted for less than two years and few Leon Bollee cars were made.

Rosengart

France, 1928 – 1955

The first Rosengart cars were made in the old Bellanger factory under the direction of Lucien Rosengart and Jules Salomon (the designer of the original Citroëns). The Rosengart cars were Austin Sevens built under licence, and differed from their British prototypes mainly in matters of styling: for example the ribbon radiator shells, not adopted by Birmingham until late 1930. Production had reached 28 Rosengart cars a day by the summer of 1930, and the Austin theme was continued by Rosengart cars until the end of pre-World War 2 production, though 1932 and subsequent Rosengart cars had a longer wheelbase and semi-elliptic rear suspension. By 1939, when a roadster Rosengart car could be bought for the equivalent of £78, the chassis had channel-section side members. In the 1932 range of Rosengart cars there was also a 1.100cc 20bhp 6-cylinder, which Rosengart car was virtually an elongated 5CV with 3-speed gearbox and vacuum-servo brakes. A line of fwd 4-cylinder sv Rosengart cars began in 1933, with transverse independent front suspensions, built under Adler licence and based on the German company’s 1.6-litre Trumpf. A more conventional rear-driven Rosengart car was sold ast he ‘8/40’.

Fwd Rosengart cars were still marketed in 1939, but by this time the Rosengart cars were based on the 11CV Citroën, from which they derived their 1.9-litre ohv engines, 3-speed synchromesh gearboxes, and hydraulic brakes. Sporting 2-door saloon Rosengart car and cabriolet bodies were mounted on a platform-type chassis. Similar bodies were used on the 1947 Super-Trahuit, but the Super-Traction fwd structure now housed a 95bhp 3.9-litre sv Mercury engine. Such a car was an unrealistic proposition in the prevailing economic climate, and 1952 brought Rosengart cars a return to the Austin Seven theme – the sv 747cc engine now gave 21bhp, and the Rosengart Ariette and Rosengart Artisane saloons had modern styling, transverse independent front suspension and hydraulic brakes. Speeds of 60mph were claimed on these Rosengart cars.

The last of the line of Rosengart cars, the Rosengart Sagaie of 1954, abandoned the old sv four in favour of a 40bhp, 750cc, ohv air-cooled flat-twin engine. Saloon and convertible models Rosengart cars were made, and it was said to do 70mph, but failed to compete with Renault and Panhard.
