Between 1923 and 1943, Yellow Coach built transit buses, electric-powered trolley buses, and parlor coaches.

Founded in Chicago in 1923 by John D. Hertz as a subsidiary of his Yellow Cab Company, the company was renamed "Yellow Truck and Coach Manufacturing Company" in 1925 when General Motors (GM) purchased a majority stake. After GM completely acquired the company in 1943, it was merged with GM's truck division to form the GM Truck & Coach Division.

The car rental subsidiary (known both as ''Hertz Drivurself Corp'' and ''Yellow Drive-It-Yourself'') was purchased back by John Hertz in 1953 through The Omnibus Corporation and floated the following year as The Hertz Corporation.

George J. Rackham, whose career had commenced with the London General Omnibus Company after the First World War, spent the years 1922–1926 in the U.S., and recognised the advantage of low swept chassis frame for bus development while employed by Yellow. It is likely that he was recruited by Hertz to help start up the bus building business. In 1926, he returned to England to join Leyland Motors as Chief Engineer and was responsible for the groundbreaking Titan and Tiger models.<ref>{{cite book|last=Townsin|first=Alan A. and Senior John A.|title=The Best of British Buses No.1 Leyland Titans 1927-42|year=1979|publisher=Transport Publishing Company|location=Glossop|isbn=9780903839563|pages=7}}{{cite book|last=Townsin|first=Alan A.|title=Blue Triangle: Alan Townsin Looks at AEC Buses|year=1994|publisher=Venture Publications|location=Glossop|isbn=189843204X|pages=59}}</ref>

GM purchased the company outright in 1943, merging it into their GM Truck Division to form GM Truck & Coach Division.<ref name=photobook/> Although GM continued with the Yellow Coach T-series and P-series product lines, the Yellow Coach badge gave way to the '''GM Coach''' or just '''GM''' nameplate in 1944. Widespread production of Yellow Coach designs—including certain ZIS buses produced in the Soviet Union—continued until 1959. Limited production of the two remaining small-capacity "Old Look" models (3101/3102 and 3501/3502) would continue until 1969.<ref name="omot.org">{{cite web|title=Ohio Museum of Transportation - GM/Yellow Coach Old-Look Transit Production Lists|url=http://www.omot.org/roster/GMOldLookList/index.html|website=www.omot.org|access-date=2 April 2018}}</ref> '''GMC''' badges did not appear until 1968.

== Models produced ==

=== Letter series (1923–1936) === Yellow started its model designation at the end of the alphabet and worked forward. Initially four types were offered: * Z type single-deck bus or coach * Z type double-deck bus * Y type coach * X type bus or coach. All were conventional front-engine design vehicles powered by Yellow Knight I4 sleeve-valve gasoline engines, or a General Electric gas-electric hybrid unless noted otherwise. The Knight engine was connected to the rear wheels by a mechanical drive shaft. In gas-electric models, a gasoline engine in front supplied electric power to two large electric motors mounted on the rear axle.<ref>{{cite web|title=Yellow Coach Part 1, Yellow Coach Mfg.

In 1931, Yellow Coach introduced its 700 series buses, featuring one of the first bus designs to mount the engine in the rear.<ref name="RoessWheelsThatDroveNY" /> Mounting the engine in the rear represented a significant innovation,<ref name="RoessWheelsThatDroveNY" /><ref name="RearEngineRevolution">{{cite web|title=A Century of Transport - Front to Back; A Rear-engined Revolution|url=http://www.wythall.org.uk/transhisa.asp|website=www.wythall.org.uk|publisher=Transport Museum Wythall (UK)|access-date=28 March 2018|language=en|archive-date=28 March 2018|archive-url=https://web.archive.org/web/20180328231819/http://www.wythall.org.uk/transhisa.asp|url-status=dead}}</ref> reducing mechanical losses, noise, and weight of a long drive shaft and exhaust running between a front engine and the rear drive and tailpipe.<ref>{{cite web|title=Choosing the best bus body style for your build|url=http://www.buslandia.net/blog/2016/10/11/choosing-a-body-style-length|archive-url=https://web.archive.org/web/20170426110318/http://www.buslandia.net/blog/2016/10/11/choosing-a-body-style-length|url-status=usurped|archive-date=April 26, 2017|website=Buslandia|access-date=28 March 2018}}</ref> Bus manufacturers in Germany and the United Kingdom would not perfect rear-engine models until the 1950s.<ref name="RearEngineRevolution" /><ref name="DaimlerRearEngine">{{cite web|title=Buses after the merger: the long road to the rear-mounted engine {{!}} marsMediaSite|url=http://media.daimler.com/marsMediaSite/en/instance/ko/Buses-after-the-merger-the-long-road-to-the-rear-mounted-engine.xhtml?oid=9361530|website=marsMediaSite|publisher=Daimler AG (Germany)|access-date=28 March 2018|language=en-EN|quote=The first bus with a rear-mounted engine debuts in 1951}}</ref> Customers did not always prefer rear-engined designs, noting that front engines were easier to access, and placed engine noise and vibration away from passengers and sometimes outside the coach body.<ref name="RoessWheelsThatDroveNY" /> Eventually, the 700 series included both front- and rear-engined models.

In 1934, Dwight Austin, patent-holder on an innovative rear-drive system, was hired by Yellow Coach and soon developed new models in the 700-series with transverse engines and a “V” angle drive. The V-drive and other innovations introduced in the 700 series would become long-lasting standards: air conditioning, diesel engines, a flat front, a high passenger floor (with luggage beneath), and unibody construction. The V-drive would be GM's standard configuration until the 1980s.<ref name="Rothacker">{{cite web|last1=Rothacker|first1=David|title=Greyhound Buses Through the Years; Part 1|url=http://www.daverothacker.com/files/greyh1-1.pdf|website=Rothacker Reviews|access-date=28 March 2018|archive-date=29 December 2009|archive-url=https://web.archive.org/web/20091229132459/http://www.daverothacker.com/files/greyh1-1.pdf|url-status=dead}}</ref>

==== Greyhound (intercity) buses: Models 719 and 743 ==== For Greyhound Lines, an operator of intercity bus service, Yellow Coach developed model ''719'' in 1936 which introduced the high floor, underfloor luggage storage, a flat front and streamlined styling. In 1937, model 719 was revised to become model ''743'' and introduced air conditioning and a diesel engine. Models 719 and 743 were both branded as the ''Super Coach'' by Greyhound, and sales were effectively limited to Greyhound and its affiliates.

By 1940, Model 1200 series designs were renamed into either the ''T''- or ''P''-series. The new model designations indicated type, fuel, propulsion (for transit) or customer (for parlor), seating capacity, and version number. (The first was -01, the second, -02, and so on.)<ref name="coachbuilt.com"/>

=== T-series (1940–1942) === All "T"-series models were urban transit buses. The model designation consisted of two or three letters followed by four numbers. These gave a basic description of the type of bus: {| class="wikitable" |- ! Type !! Fuel !! Transmission !! !! Nominal seating capacity !!

All models were rear-engined except the 21xx and 24xx series.

===GM and GMC===

In 1944, General Motors completed its acquisition and merger of Yellow Coach. The T-Series and P-Series production and series numbering continued under the GM and GMC bus brands, along with other variants such as B-Series school buses and S-Series suburban buses. Yellow Coach designs would continue to be widely produced until 1959, when GM introduced its New Look models. The last Yellow Coach design ceased production in 1969.<ref name="omot.org"/>
