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.

Premier

US, 1903 – 1925

(1) Premier Motor Mfg Co, Indianapolis, Ind.

(2) Premier Motor Corp, Indianapolis, Ind.

The Premier car started life as a conventional machine made on modern lines, with a pressed-steel frame, mechanically-operated inlet valves, and shaft drive. A four-cylinder air-cooled Premier car was made in 1905. The designer of the Premier car was G.A. Weidely, who made his name with proprietary engines. A line of conventional water-cooled big fours and six-cylinder Premier cars followed, starting with a 24/28hp Premier car in 1907. From 1913, sixes alone were built, the ‘Premier 48’ at $3.250 having a capacity of over 8 litres. The special racing Premier cars of 1916 had a twin ohc, 4-cylinder, 16-valve engine reminiscent of the Peugeot. The touring Premier car of 1919 – 1920 was notable mainly for its use of the Cutler-Hammer Magnetic Gear Shift, an electric transmission system controlled by a lever mounted on the steering wheel. The ohv 4.8-litre engine of the Premier car was an unusually advanced six, with aluminium block, crankcase and pistons, and iron liners.

GB, 1906 – 1907; 1912 – 1913

Premier Motor Co Ltd, Birmingham

The Premier car company were concessionaires for the Italian Marchand car, and the 1906 4-cylinder Premier car was, in fact, a Marchand. Towards the end of 1906 Premier cars launced a short-lived two-seater of their own design powered by a 10/12hp Aster engine, but no further Premier cars appeared until the cyclecar boom of 1912. This brought two distinct designs of Premier cars: the PMC Motorette 3-wheeler with a rear-mounted 6hp single-cylinder engine driving the rear wheel by chains; and the more conventional Premier car, a 4-wheeler using an 8hp 2-cylinder engine, and chain drive.

D, 1913 – 1914

Justus Christian Braun Premier – Werke AG, Nuremberg

After producing the Kaiser cars this firm offered a new model in 1913 under the name of Premier. This Premier car was a two-seater sports car with a 1.030cc 4/12PS engine. This Premier car was also built in the company’s Austrian factory at Eger and was marketed as the Omega.
