Duesenberg

US, 1920 – 1937, 1966

(2) Duesenberg Corporation, Indianapolis, Ind., 1966

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.

Marmon

US, 1902 – 1933

(1) Nordyke and Marmon Co, Indianapolis, Ind., 1902 – 1925

(2) Marmon Motor Car Co, Indianapolis, Inc., 1926 – 1933

Howard Marmon’s first cars were advanced machines, featuring air-cooled V4 engines of oversquare dimensions, with mechanically-operated overhead valves and pressure lubrication. Something approaching independent front suspension was achieved on Marmon cars by the use of double-three-point suspension, with a separate sub-frame for engine and transmission. Only the 2-speed gearbox of planetary type conformed on the Marmon cars to American practice of the period. These Marmon cars persisted until 1908, though 1907 brought the introduction of selective sliding-type gearboxes on the Marmon car and a short-lived 60hp V8. In 1908 buyers of Marmon cars had the choice of air or water cooling and cylinder heads were detachable. The following year Marmon went over to conventional T-head in-line fours rated at 40/45hp and 50/60hp, and two years later only the 5.2-litre Model 32 Marmon car with rear-axle gearbox was listed. Marmon cars did well in contemporary competition, with 54 1st places logged with a Marmon car between 1909 and 1912; Ray Harroun won the first Indianapolis 500 in 1911 with a specially-built 6-cylinder Marmon car, the well-known Marmon Wasp. An enormous 9.3-litre six rated at 48hp was available in 1914.

In 1916 the advanced ohv 6-cylinder Marmon 34 with aluminium cylinder block, body, bonnet and radiator shell, and double transverse rear suspension was introduced. The engine capacity of this Marmon car was 5½-litres, and its output 74bhp; developments of this Marmon car were still listed as late as 1927, acquiring Delco coil ignition in 1920, and the option of a Marmon car with front wheel brakes in 1923. The Marmon cars were expensive: $5.000 was asked for a touring car in 1921. A not very successful 3.1-litre ohv straight-8 in the Marmon car appeared in 1927, but the following season only Marmon cars with eights were made, the cheapest sv Marmon 68 selling for $1.395. In 1928 Marmon also entered some front-wheel-drive Marmon cars at Indianapolis, but they were in fact only revamped Millers. The Marmon car company sold 22.300 Marmon cars in 1929, thanks to a cheap new straight-8 at under $1.000, the Marmon Roosevelt. This brandname, however, did not last, for the Marmon car appeared in the 1930 programme as the Marmon R, along with three other eights, the sv 69, and two big ohv Marmon cars with 4-speed gearboxes and capacities of the 4.9- and 5.2-litres respectively.

Marmon cars swansong was the magnificent 9.1-litre 200bhp 16-cylinder model of 1931. This Marmon car was beautifully proportioned, and had an alloy engine. The list price of the Marmon car was $4.925; there was a companion Marmon 8-125 in 1932, but only the Marmon Sixteen was listed for 1933. At the very end Marmon was testing a Marmon car with a 150bhp V12 with independent front suspension, De Dion rear axle, and tubular backbone frame, but this never saw production.
