Fred and August Duesenberg were self-taught mechanics and car builders whose careers began in the Midwest at the start of the twentieth century with the manufacture of Mason and Maytag cars. Fred was five years older than August and was the designer and tinkerer of the pair. Augie complemented his brother by bringing the ideas and creations to life.
The talents of the Duesenberg brothers influenced many early American auto manufacturers, with their four-cylinder engine produced by Rochester being used to power around six different marques. Legendary drivers of the era who drove vehicles powered by Duesenberg-designed engines included Rex Mays, Peter DePaolo, Tommy Milton, Albert Guyot, George Souders, Ralph DePalma, Ab Jenkins, Deacon Litz, Joe Russo, Jimmy Murphy, Jimmy Gleason, Eddie Rickenbacker, Joe Boyer, Fred Frame, L.L. Corum, Roscoe Sarles, Harry Hartz, Ralph Mulford, and Stubby Stubblefield.
Duesenberg cars raced at the inaugural Indianapolis 500 in 1913. 70 Duesenbergs would compete over 15 consecutive starts at the Indy 500, with thirty-two of them finishing in the top 10. At the 1922 Indy 500, eight of the top 10 cars were powered by Duesenberg engines. In 1921, a Duesenberg driven by Jimmy Murphy won the French Grand Prix at Le Mans.
The car, called the 'Murphy Special,' had a Duesenberg chassis and a Miller engine, and was the first car with hydraulic brakes to start a Grand Prix.
The Duesenberg brothers were world-class engineers, but they were terrible businessmen and lacked the necessary administration skills needed to run a business. Their first passenger car was called the Model A, and they were unable to sell all of the units. The Model A was powered by a Duesenberg Straight-8 engine, the first 'mass-produced' straight-eight engine in the United States. The engine was a single overhead-camshaft unit with four-valve cylinder heads. It had 16-inch hydraulic brakes, designed by Fred in conjunction with Lockheed, and was one of the most advanced and powerful, fastest, and expensive automobiles on the market.
The model experienced production delays and dealers were slow to receive deliveries. The goal had been to produce 100 examples per month, but this proved too difficult to achieve, and the factory was barely able to produce one per day. Over six years, approximately 650 Model As were sold.
The Model A was followed briefly by the Model X, with around 13 examples being built. They were similar to the Model A, but longer, heavier, and had a 100-horsepower engine. They also had hypoid differentials and all the valves were on one side.
On October 26th of 1925, Errett Lobban Cord acquired the Duesenberg Company, mainly for the brothers' talents and engineering skills. The Duesenberg Motor Company was added to E.L. Cord's rapidly-growing enterprise, the Auburn Automobile Company. It was Cord's vision that this new acquisition would compete and surpass the best automobiles being produced in America and Europe. Cord tasked Fred Duesenberg with the monumental task of building the greatest car in the world - the Model J.
The Duesenberg Model J was introduced on December 1st of 1928 at the New York Auto Salon. The reputation of the Duesenberg and Cord marque made the Model J front-page news and trading was halted on the New York Stock Exchange for the announcement. Duesenberg ordered enough components to build 500 examples while development continued for six months after the Model J's introduction. The finest materials were used throughout and each completed chassis was driven at speed for 100 miles at the Indianapolis Motor Speedway. The short wheelbase chassis was nearly 12 feet long, measuring 142.5 inches. The 420 cubic-inch engine had double overhead camshafts, four valves per cylinder, and eight cylinders offering 265 horsepower.
Five months before Black Tuesday and the Stock Market crash, the first customer took possession of the Model J in May of 1929. The utopia was short-lived, as the decimated economy meant the pool of capable buyers drastically dwindled. Lacking financing and support from E.L. Cord and Auburn Corporation, the Duesenberg soldiered on guided by their advertising slogan, 'He drives a Duesenberg' and 'She drives a Duesenberg.' These black-and-white advertisements were drawn by Paul Gerding and became the images Americans associated with success, wealth, privilege, success, and power. The car's external exhaust pipes were a symbol of performance and power.
During this era, a new family sedan sold for approximately $500, while the coach-built Duesenbergs often cost in the vicinity of $20,000. The cost of the short-wheelbase chassis began at approximately $8,500.
The powerful engine was designed to easily carry the imposing coachwork hand tailored to the customer's needs, desires, and specifications. About half of the Models Js built had coachworks created by the company's chief body designer, Gordon Buehrig. These in-house bodies used the name of La Grande. The rest were from independent coachbuilders such as Rollston, Walker, Weymann, Willoughby, Derham, Holbrook, LeBaron, Murphy, and Judkins. The list of European coachbuilders includes Gurney Nutting, Saouthick, Franay, and Fernandez et Darrin.
The Murphy Body Company of Pasadena, California is generally recognized as the most successful builder of Model Js. At least 125 bodies were built by Murphy for the Model J, with the most popular being the Disappearing-Top Roadster and the Convertible Sedan, with approximately 50 individual bodies built in total. Most of the designs are credited to W. Everett Miller. The open-body style designs became so popular by the early 1930s, Murphy began constructing these bodies 'in the white' so that customers would not have to wait months to receive coachwork for their new Duesenberg.
Another popular coachbuilder was LeBaron who - along with Murphy and Holbrook - were selected to build bodies for the first Model Js, which were displayed at the model's 1929 debut in New York. 28 of the 38 LeBaron bodies wore the Ralph Roberts-designed Dual Cowl Phaeton style, in both sweep-panel and barrel-side configurations.
The straight-eight engine powering the Model J was based on the tried-and-true racing engines of the 1920s designed by Duesenberg. Manufacturing was handled by the Lycoming Company of Williamsport, Pennsylvania, another company owned by Cord. The engine gave the Model J a top speed of 119 mph, and 94 mph in second gear.
Two versions of the chassis were offered with one being the long 153.54-inch platform and the other being the short 141.73 inches. Other special sizes were built, including two SSJs with a wheelbase shortened to 125 inches.
A few cars had a 160-inch wheelbase.
A supercharged version often referred to as the SJ, brought horsepower to 320 hp and was introduced in May of 1932. Just 36 examples were built. The supercharger was placed beside the engine, which means the exhaust pipes were bent and extended through the side panel of the hood. These shiny tubes, a registered trademark of Cord and used on other supercharged cars from Cord and Auburn, helped distinguish the supercharged models from the naturally aspirated cars.
The Great Depression hit in October 1929, and by this point around 200 examples of the Model J had been built. An additional 100 orders were received in 1930, which meant the Model J did not achieve the original goal of selling 500 cars a year. Between 1928 and 1937, 481 Model Js of all versions were built, including the SJ, SSJ, and SJN. Although production lasted nearly a decade, the design remained mostly unchanged.
Among the list of major modifications include the four-speed gearbox, which was replaced with a three-speed unsynchronized unit early in the Model Js production as it was unable to cope with the engine's power.
Most of the chassis and engines were built in 1929 and 1930, but due to the astronomical cost and the Depression, many were sold in subsequent years. The year in which the Model J received its body is considered the date on which it was built, even though the chassis had been built year(s) earlier.
The Model J was the most expensive and fastest American automobile in the market.
