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.

Maybach

D, 1921 – 1941

Maybach Motoren-Werke GmbH, Friedrichshafen

Wilhelm Maybach left the Daimler company in 1907. Together with Count Zeppelin he founded a factory primarily for the production of aero engines, especially for the Zeppeling air-ships. These engines were designed by Karl Maybach, Wilhelm’s son. After World War 1, Karl Maybach started to build a 22/70ps 5.7-litre 6-cylinder engine intended for motor cars. This Maybach engine was used by Spyker, but no other factories were interested, so Maybach decided to take up Maybach car production on his own. From the beginning Maybach cars aimed at a high quality car with outstanding driving comfort. The first Maybach Model W3 appeared at the 1921 Berlin Motor Show, and this Maybach car featured a very advanced 2-speed pedal-controlled transmission. This Maybach carmodel was produced until 1926. It was followed by the ohv Maybach Model W5 (for sale in 1926 – 1930) using a 27/120ps 7-litre engine in the same chassis, this being available with Maybach’s Schnellgang 2-speed auxiliary box, giving the Maybach car 4 forward speeds. The Maybach 12 of 1929 had a V12 7-litre engine, which was superseded one year later by the Maybach Zeppelin, also with V12 7-litre engine of 150bhp; after 1931 the Maybach car was also available with an 8-litre 200bhp engine. The Zeppelin range was listed until 1939. Maybach Zeppelin car chassis were also fitted with 6-cylinder engines of 7-litres capacity (already used in Maybach Model W5) and a new 5.2-litre engine developing 130bhp (the Maybach W6 and DSH models respectively). These Maybach cars retained beam axles to the end and were characterized by 7-speed boxes of great complexity. A Zeppelin chassis for the Maybach car cost the equivalent of £1.300 in Germany.

In 1935 a new 6-cylinder Maybach car was presented, starting the SW range. This was the Maybach SW35 with a 3.5-litre 140bhp engine. Engine capacity of this Maybach car was raised to 3.8-litres in the Maybach SW38 in 1936 and to 4.2-litres in the SW42 of 1940. Production of the Maybach car ceased in 1941. The Maybach Zeppelin shared with the Mercedes 770 the claim to be the most exclusive German car of the 1930s. This reputation was enhanced by Maybach cars high standards of material and finish, of comfort and quietness in running. No less well-made were the 6-cylinder Maybach cars which were in the first rank of German cars of this class. Maybach only built complete chassis for their Maybach cars, bodies being made by various firms to customers’ special requirements. Best known of these firms was Spohn of Ravensburg. Spohn aslo built aerodynamic bodies to Jaray designs for the Maybach Zeppelin in 1932 and 1934, and for the Maybach SW35 in 1935. These versions Maybach cars were produced only in very limited numbers. Maybach car production was not taken up again after World War 2. Altogether, some 2.000 Maybach cars are believed to have been made. In 1960 Maybach cars pooled their interests with Daimler-Benz in the manufacture of diesel engines for locomotives and ships.
