Fred Duesenberg began by making bicycles and designed his first Duesenberg car, the Mason, in 1904. He and his brother August made engines with horizontal overhead valves for the 1912 Mason racing cars, and founded Duesenberg Motors in the following year in order to produce marine engines and complete racing cars bearing the Duesenberg name. The most famous of the latter appeared in 1920: a 3-litre Bugatti-inspired Duesenberg straight-8 with single overhead camshaft and three (vertical) valves per cylinder. This Duesenberg won the 1921 French Grand Grand Prix. In the 1920s the Duesenberg racing cars were the great rivals of the Millers at Indianapolis, and victory was assured in 1924 by the adoption of a centrifugal blower on Duesenberg cars. Though a two-stroke 1½-litre 8-cylinder racing engine capable of 7.000rpm was made in 1926, this was not proceeded with. The horizontal-valve Duesenberg engine was taken over in 1920 by the Rochester Motor Manufacturing Co Inc and was used in various sporting and luxury cars.

Meanwhile, at the end of 1920, the first Duesenberg production car made its debut. This Duesenberg Model A was an extremely expensive, if very advanced, luxury car, embodying an 8-cylinder in-line engine – the first to be seen in an American production car – of 4.2 litres, basically similar to the Duesenberg racing unit, but with only two valves per cylinder and developing about 100bhp. There were also hydraulically-operated front wheel brakes – another ‘first’ as far as America was concerned. The Model A was current until 1926. A handful of its little-altered successor, the Duesenberg Model X, was made in 1926-1927, but in the former year E.L. Cord of Auburn acquired control of the Duesenberg company. He stipulated that Fred Duesenberg’s next car should be completely new, and a quite exceptional machine. In fact, the Duesenberg Model J, which made its bow at the end of 1928, was the most remarkable automobile in America: bigger, faster, more elaborate and more expensive than any other, yet also superior to them in refinement and good looks. Its 6.9-litre, 8-cylinder engine, made by Lycoming (a firm which Cord had also bought), had two chain-driven overhead camshafts operating four valves per cylinder; a layout of racing type unique among American cars at the time and said to develop 265bhp at 4250rpm – more than double the output of any rival. Although the complete Duesenberg car weighed more than 4980lb, it was claimed to be capable of 116mph in top gear and 89mph in second. Only Duesenberg Model J chassis were made for which $8500 was asked in 1929. Immensely long and strong and lowbuilt, Duesenberg cars were very popular with all the leading coachbuilders. The Duesenberg company preferred to sell cars complete with bodies designed by them but made by approved builders, such as Murphy, Bohman & Schwarts, Judkins, Derham and Le Baron. In this form, catalogued Duesenberg models cost up to $17.950. The transmission – apart form the double dry-plate clutch – was conventional, as was the suspension by half-elliptic springs and hydraulic shock absorbers. The brakes, of course, were hydraulic, with vacuum servo assistance from late 1929.

In 1932 a supercharged version of the Model J, the Duesenberg SJ, was added. To cope with the 320bhp now alleged to be available, bearings, reciprocating parts and valve springs were strengthened. Usually, the shortest Duesenberg J chassis was used, with the highest axle ratio and stronger front springs. A maximum speed of 129mph was attributed to the Duesenberg SJ, with an acceleration figure of 0-100mph in 17 seconds.

Duesenberg survived the Depression, but died in the collapse of the Cord Corporation in 1937. Attempts to revive the Duesenberg name were made in 1947 and in 1966. The first Duesenberg was unsuccessful, and in 1966 only one Duesenberg car was actually made, powered by a 7-litre V8 Chrysler engine with push-rod overhead valves, developing 431bhp at 5.000rpm. Transmission was automatic, front suspension was independent, and there were disc brakes. Body styling was by Ghia. This Duesenberg venture, too, collapsed.

Wanderer

The Wanderer firm – like many others – started with bicycle manufacture; motor cycles followed and led the way to Wanderer cars. Extensive experiments with Wanderer cars were undertaken. In 1905 the 2-cylinder Wanderermobil was ready, but this Wanderer car remained a prototype. Another Wanderer car – which is still in existence – is claimed to date from 1904.

It is reported by some sources that Ettore Bugatti offered a small car design to Wanderer in 1910 before starting manufacturing on his own. But Wanderer cars did not take over the Bugatti car, as their own Wanderer car designs were ready and they started production of these Wanderer cars in 1911. Their first production Wanderer car had a 4-cylinder 1.150cc, 5/12PS engine and a two-seater tandem body. This Wanderer car was popularly known as the Püppchen (doll). Engine capacity was increased to 1.220cc in 1914 and the output raised to 5/15PS. Three- and four-seater Wanderer cars were also available and this model Wanderer carwas listed until 1922. Some 4-cylinder models Wanderer car in the 1½- and 2-litre range followed udring the 1920s. A 6-cylinder Wanderer car (the W11) with a 2.540cc 50bhp engine was built under licence by Martini of Switzerland. The W11 was also available in a sports version of 2.995cc and 65bhp. In addition to 4-cylinder Wanderer cars, a range of 6-cylinder cars was built during the 1930s which were based on a Porsche design. These Wanderer cars had push-rod ohv engines, and later cars had swing-axle rear suspension.

A very sporty looking Wanderer car appeared in 1936, the W25K (K for Kompressor). The 1.936cc engine with blower developed 85bhp and the Wanderer car easily reached 93mph. However, this Wanderer car did not figure much in competitions and was produced in limited numbers only. After 1932 Wanderer was a member of the Auto Union. Their cars had a reputation for quality, finish and good performance although they were intended for workaday use. In the Auto Union catalogues they represented the ‘upper middle-class’. Wanderer car production ceased at the outbreak of World War 2 in 1939, by which time two sv models, with all-round independent suspension, a 1.8-litre four and a 2.6-litre six, were being offered.
