Duesenberg

Fred and August Duesenberg began designing engines in the early 1900s, after Fred became involved with bicycle racing. The brothers designed a vehicle in 1905, and they formed the Mason Motor Car Company in 1906 with funds from lawyer Edward R. Mason in Des Moines, Iowa. F. L. and Elmer Maytag acquired a majority stake in the company and renamed it the Maytag-Mason Automobile Company until they sold their stake in 1912.

The Duesenberg brothers then moved to Saint Paul, Minnesota, where they established the Duesenberg Motors Company in 1913. Eddie Rickenbacker drove the first Duesenberg-designed vehicle to race at the Indianapolis 500 in 1914, placing tenth. During World War I, the Duesenbergs designed and built aircraft engines in Elizabeth, New Jersey. A Duesenberg driven by Tommy Milton won the 1919 Elgin Trophy. In 1919, the brothers sold their Saint Paul factories.

In 1920, the Duesenberg brothers relocated to Indianapolis, Indiana, where they founded the Duesenberg Automobile & Motors Company, manufacturing the Duesenberg Model A. The brothers assumed engineering roles after signing over the naming rights and patents for Duesenberg engines to promoters Newton E. Van Zandt and Luther M. Rankin. The first Model A was commissioned by Hawaiian businessman and politician Samuel Northrup Castle. The car had a 260-cubic-inch (4.3 L) straight-eight engine that output 88 horsepower (66 kW), the largest engine in a commercially available vehicle at the time, and was the first to have hydraulic brakes on all its wheels.

The company continued to build race cars as well, and a Duesenberg driven by Jimmy Murphy won the 1921 French Grand Prix, the first American car to do so. Duesenberg cars also performed well at the Indianapolis 500 during the 1920s, winning the race in 1922, 1924, 1925 and 1927.

Van Zandt left the company in 1921, after which it struggled financially and entered receivership in 1924. Duesenberg was purchased by Errett Lobban Cord in 1926. August's role in the passenger-car side of the business declined after Cord's takeover, and August worked primarily in Duesenberg's racing division after 1926, designing all Duesenberg race cars built from that year until the company's dissolution. Two years later, Cord had the Duesenbergs make a new model to "outclass" all other American cars. In 1929, the company began selling the Duesenberg Model J, which was powered by a 265-horsepower (198 kW) straight-eight engine. The body and cabin were custom-built by coachbuilders. Prices for the cars ranged from $14,000 to $20,000 at the time.

Duesenbergs were considered to be among the most luxurious American cars ever made. Historian Donald Davidson called them the "most prestigious passenger car" in American history and likened them to an American version of the Rolls-Royce. The vehicles were popular with movie stars, royalty and other wealthy individuals. The company was sold by Cord and dissolved in 1937. The last Duesenberg to be made by the original company was completed in 1940, commissioned by German artist Rudolf Bauer and completed by August Duesenberg after the company had shut down.

In 1998, The Franklin Mint started producing collectible scale models of Duesenberg Coupé Simone, a fictitious custom-made luxury car allegedly manufactured in the late 1930s.

Revivals

Several unsuccessful attempts were made to revive the Duesenberg name. August Duesenberg failed to restart the company in 1947, and an attempt by his son, Fritz, and car designer Virgil Exner to revive the brand failed after the production of one concept car in 1966. In 1970, Bernard Miller bought the Duesenberg Corporation and produced the SSJ model from templates taken from the original 1935 SSJ La Grande body. The body was aluminum over ash. There were grand plans for over 300 SSJ's to be produced but over the company's life span of 1970-1974 only 8 were completed.

Model A (1921–1927)

Duesenberg's first car was the Model A. It is powered by the Duesenberg Straight-8 engine and was the first car to be mass-produced with a straight-eight. The purchase price for a Model A started at $6,500 (equivalent to $123,000 in 2025). The Duesenberg Model A introduced several innovative features, such as an overhead camshaft, four-valve cylinder heads, and the first four-wheel hydraulic brakes offered on a passenger car. It had the largest engine of any consumer vehicle at the time of its production.

The Duesenberg Model A experienced various delays going from prototype to production. Deliveries to dealers did not start until December 1921. Sales lagged, and Duesenberg could not meet a 100-vehicles-per-month quota as the Indianapolis plant struggled to roll out one a day. In 1922, no more than 150 Duesenberg Model As were manufactured, with only a total of 650 units sold over a period of six years.

Model X (1926–1927)

The Model X is a sportier version of the Model A with a heavier and longer (136 in (3,500 mm) wheelbase) chassis and 100 hp (75 kW) engine that enabled it to reach 100 mph (161 km/h). The most notable differences between the A and the X were that the latter had hypoid differentials and all its valves were on one side.

The Duesenberg Model X chassis is an upgrade over the Model A chassis, offering a reworked 260-cubic-inch (4.3 L) straight-8 engine, an overhead cam, with a new crankshaft, revised valve train, improved pistons and superior intake manifold. Power is 100 hp, which made driving at 100 mph (160 km/h) possible. The chassis length increased to 136 inches (3.5 m), with additional reinforcements. Improved leaf springs are mounted above the frame rails, thus, lowering the center of gravity. The Duesenberg Model X chassis is the rarest Duesenberg street production chassis ever made, with only thirteen ever manufactured. Only five of the Duesenberg Model Xs manufactured are known to have survived.
