'''Duesenberg Automobile & Motors Company, Inc.''' was an American [[race car|racing]] and [[luxury car|luxury automobile]] manufacturer founded in [[Indianapolis]], Indiana, by brothers [[Fred Duesenberg|Fred]] and [[August Duesenberg]] in 1920. The company is known for popularizing the [[straight-eight engine]] and four-wheel [[hydraulic brakes]]. A Duesenberg car was the first American car to win a Grand Prix race, winning the [[1921 French Grand Prix]]. Duesenbergs won the [[Indianapolis 500]] in [[1922 Indianapolis 500|1922]] (when eight of the top ten finishers were Duesenbergs), [[1924 Indianapolis 500|1924]], [[1925 Indianapolis 500|1925]] and [[1927 Indianapolis 500|1927]]. Transportation executive [[Errett Lobban Cord]] acquired the Duesenberg corporation in 1926. The company was sold and dissolved in 1937. It was the only automotive company to go bankrupt in the Great Depression and not be rescued by the US government, largely a political move due to [[New Deal]] policies avoiding the imagery of helping the richest, despite Duesenberg being the largest employer in Indianapolis at the time.

===Revivals===
Several unsuccessful attempts were made to revive the Duesenberg name.<ref name="Star1"/> 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.<ref name="CST1">{{cite news |last1=Jedlicka |first1=Dan |title=Marriage of muscle and magic; No car holds a candle to Duesenberg |work=[[Chicago Sun-Times]] |date=January 24, 1999}}</ref><ref name="DFP1">{{cite news |last1=Phelan |first1=Mark |title=The Last Duesenberg is about to go to auction |work=[[Detroit Free Press]] |publisher=[[Gannett]] |date=July 14, 2019}}</ref> In 1970, Bernard Miller bought the Duesenberg Corporation and produced the SSJ model from templates taken from the original 1935 SSJ La Grande body.

Duesenberg's first car was the Model&nbsp;A.

The Duesenberg Model A experienced various delays going from prototype to production. Deliveries to dealers did not start until December 1921.{{r|"Borgeson1"|p=40}} 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{{spaces}}As were manufactured, with only a total of 650 units sold over a period of six years.{{r|"Mueller1"|p=52}}

===Model X (1926–1927)===
The Model X is a sportier version of the Model{{spaces}}A with a heavier and longer ({{convert|136|in|mm|abbr=on}} [[wheelbase]]) chassis and {{convert|100|hp|kW|0|abbr=on}} engine that enabled it to reach {{convert|100|mph|km/h|0|abbr=on}}.<ref name="Kimes1"/> The most notable differences between the A{{spaces}}and the X were that the latter had hypoid differentials and all its valves were on one side.<ref name="Wolff1"/>

The Duesenberg Model X chassis is an upgrade over the Model{{spaces}}A chassis, offering a reworked {{convert|260|cuin|l|adj=on}} straight-8 engine, an overhead cam, with a new crankshaft, revised valve train, improved pistons and superior intake manifold. Power is 100&nbsp;hp, which made driving at {{cvt|100|mph}} possible. The chassis length increased to {{convert|136|in|m}}, with additional reinforcements. Improved leaf springs are mounted above the frame rails, thus, lowering the center of gravity. The Duesenberg Model{{spaces}}X chassis is the rarest Duesenberg street production chassis ever made, with only thirteen ever manufactured.

The first Model J prototype was created in 1927 and the first cars were delivered in 1929, shortly before the onset of the [[Great Depression]]. About three hundred Model{{spaces}}Js were completed by 1930, short of the original 500-vehicle goal.<ref name="MSN1">{{cite web |last1=Ema |first1=Randy |title=The Duesenberg: The Grandest Yet |url=http://autoshow.autos.msn.com/autoshow/pebblebeach2007/Article.aspx?cp-documentid=5257881 |website=[[MSN]] |access-date=April 14, 2022 |archive-url=https://web.archive.org/web/20120216133550/http://autoshow.autos.msn.com/autoshow/pebblebeach2007/Article.aspx?cp-documentid=5257881 |archive-date=February 16, 2012 |date=August 8, 2007 |url-status=dead}}</ref>

Only the chassis and engine of the Model{{spaces}}J were displayed, as the body and cabin of the car were custom built per custom for luxury vehicles at the time. The company's chief body designer, [[Gordon Buehrig]], designed around half of the Model{{spaces}}J bodies, while the remainder were designed by coachbuilders around the world, including [[J Gurney Nutting & Co Limited|Gurney Nutting]], [[Walter M Murphy Company|Murphy]], and [[Derham Body Company|Derham]], among others.<ref name="Buehrig1">{{cite news |last1=Buehrig |first1=Gordon |title=I remember the Duesenberg |url=https://books.google.com/books?id=svPzoud4n_MC&pg=PA370 |access-date=April 14, 2022 |work=Automobile Quarterly |issue=4 |publisher=Automobile Quarterly Inc. |date=Spring 1966 |isbn=9781596131156 |language=en |archive-date=April 15, 2022 |archive-url=https://web.archive.org/web/20220415004709/https://books.google.com/books?id=svPzoud4n_MC&pg=PA370 |url-status=live }}</ref>{{rp|372}}
