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.

Oscar Seyd’s firm never built a car, though some International car offerings were assembled in their Great Portland Street Showrooms and a certain amount of work was also undertaken at the service depot in Kilburn, where International cars had been operating since 1896. The original International-Benz was in fact a French-built Roger, a car which had become hard to sell in France; International added their own improvements to the International car, among them a reverse, a British-built version of the ‘Crypto’ gear and bodywork made to their order. Single- and twin-cylinder variations on the Benz theme were offered until 1901, later International car being German-built after the demise of M. Roger’s company. In 1899 International presented a ‘light two-seater racing car’ with wheel steering, a Benz-based 12hp with wheel steering, pneumatic tyres and double phaeton coachwork on the International car at £800, and a 9hp ‘vibrationless’ flat-twin (not on Benz lines) in addition to their regular range of International car. International cars became a limited liability company in 1900, when two Coventry firms, Payne and Bates (Godiva) and Allard, were approached to make a new design for the International car. The Payne and Bates-built International car(possibly the twin-cylinder Royal with steel frame and wheel steering, offered for £367 10s) proved unsatisfactory, but Allard’s effort, the International Charette, introduced in November 1900, sold in some numbers. This International Charette car was a belt-driven light car with front vertical 823cc engine of De Dion type (designed to run at only 1.000rpm), a coal-shovel shaped bonnet and rack-and-pinion steering. It sold for £165. Early International cars were rated at 5hp (later increased to 6hp) and there were 2-speed and 3-speed variants. All International Charette chassis were delivered to London under their own power. This type International car was not offered after 1903 and apart form the Mountaineer motorcycle, the later cars of the International company were of French origin. The International Armstrong (1902) was a single-cylinder 1.100cc machine with shaft drive on Renault lines and this gave way in 1903 to the Aster-engined Portlands, also shaft-driven and offered in a variety of sizes from a 6hp single at £205 up to a big 24hp 4-cylinder car with a 4-speed gearbox.

The smallest International car, the Portland was still available in 1904, but by this time the International car company was mainly concerned with importing the Diamant car. International were defunct by 1905.

US, 1900

International Motor Carriage Co, Stamford, Conn.

This International car company showed a light car with a 2-stroke engine designed to run on paraffin at the Madison Square Garden show in 1900, but this International car did not go into production.
