History
Conceived by E. L. Cord as the finest car in the world, the Model J was unveiled at the New York Salon on December 1, 1928 (as a 1929 model). Engineered by Fred Duesenberg, its 420-cubic-inch (6.9-litre) straight-eight used double overhead camshafts and four valves per cylinder — exotic technology for any 1928 road car — and produced 265 horsepower, roughly double the output of its closest American rivals.
The Model J was sold as a chassis only — priced around $8,500 before coachwork, with finished cars reaching $14,000–$20,000 in the depths of the Depression — and clothed by the world's great coachbuilders, with many of the most admired bodies designed in-house by Gordon Buehrig. It was the car of film stars, royalty, and tycoons, and the source of the period slang 'It's a Duesy.'
Total Model J production (including the supercharged SJ) was only about 481 cars before the factory closed in 1937. Surviving examples are among the most valuable automobiles in the world.
