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.

Horch

August Horch was among the pioneers of car manufacture in Germany. He was employed as a an engineer with Benz from 1896 to 1899 when he started his own Horch car factory at Cologne. The first Horch car appeared in 1900. This Horch car had a 2-cylinder 5hp front-mounted engine and shaft drive. The next Horch models were a 2-cylinder 10/12hp and a 4-cylinder 16/20hp. After the Zwickau works had been set up in 1904 Horch was able to increase production. The Horch 18/22hp ohv 4-cylinder model of 1904 became very popular and was the basis for several subsequent Horch cars. A victory in the Herkomer Trial of 1906 was gained with this Horch car model, the first such success for a Horch. Horch also pioneered with his Horch Torpedo form aero-dynamic bodies for the Prince Henry Trials, which were built by Kathe of Halle. In 1906 a 6-cylinder 8-litre power unit was designed for Horch cars, developing 60bhp, but it was not a success and this was one cause of differences between Horch and his partners. Horch himself left the firm and started the Audi factory.

Various models with different engine sizes were included in the Horch car range, from the small Horch 6/18PS 1.588cc to the Horch 25/60PS 6.395cc. All Horch cars had 4-cylinder engines. After World War 1 the Horch 33/80PS 8.440cc model appeared, which had actually been designed in 1914. This Horch car started a series of prestige cars for which the make became famous in the following years. Paul Daimler (son of Gottlieb) was engaged as chief engineer in 1923. Ohc 4- and 6-cylinder Horch car models with fwb appeared in 1923/ 1924, but the first new Horch car under his management was the Horch 300 with a straight-8 3.230cc engine with twin overhead camshafts. In 1927 the ‘Horch 305’ and ‘Horch 306’ appeared, which also featured straight-8 engines, with twin overhead camshafts and a capacity of 3.375cc developing 75bhp. These Horch car models differed only in wheelbase. They were followed by the ‘Horch 375’ in 1928 with an 8-cylinder 3.974cc engine capable of 80bhp. After Daimler left Horch two more models (the Horch ‘400’ and ‘405’) were produced showing Daimler influence. The Horch 450 of 1930 was entirely new. This Horch car was straight-8 with only one overhead camshaft. Two different wheelbases and engines of 4, 4½ and 5 litres were available. The last of these stayed in the Horch car range until 1939, later Horch cars having 10-bearing crankshafts and all round independent suspension. Type numbers of Horch cars became a little confusing in the next few years, when some models were available with different wheelbases and engine capacities. A V12 with 5.990cc (Horch car models ‘600’ and ‘670’) appeared in 1931, followed by the V8 3.517cc ‘Horch 830B’ in 1933, available in two wheelbase and engine sizes. By 1939 the range consisted of the ‘Horch 930V’ and ‘Horch 830BL’(3.823cc, 92bhp) and the ‘Horch 951A’, ‘Horch 853A’ and ‘Horch 855’ (4.944cc, 120bhp). These Horch car models were available with different wheelbases and a variety of body styles from a two-seater roadster to a large Pullman saloon. The Horch car company was celebrated for luxurious ‘prestige’cars which were sold at lower prices than other top makes; a V8 cost £615 in England, and straight-8s from £985.

From 1932 Horch was a member of the Auto Union, and the racing cars bearing this name were built in the Horch car works. In 1945 the Horch car factory was nationalized and in 1956 it brought out a new Horch car. This had to be sold as the Sachsenring, as Auto Union, now based on Düsseldorf, hold the sole rights to the brand-names Horch, Audi and Wanderer.
