General Motors fitted the [[GM Whirlfire engine|GT-30x series of gas turbines (branded "Whirlfire")]] to several prototype buses in the 1950s and 1960s, including [[GM "old-look" transit bus#Turbo-Cruiser I|Turbo-Cruiser I]] (1953, GT-300); [[GM New Look bus#Variants based on the New Look|Turbo-Cruiser II]] (1964, GT-309); Turbo-Cruiser III (1968, GT-309); [[Rapid Transit Series|RTX]] (1968, GT-309); and [[Transbus Program|RTS 3T]] (1972).<ref>{{cite news |url=https://www.curbsideclassic.com/bus-stop-classic/bus-stop-classics-general-motors-gm-turbo-cruiser-i-ii-and-iii-urban-transit-coaches-maverick-top-gun-your-bus-is-here/ |title=Bus Stop Classics: General Motors (GM) Turbo Cruiser I, II and III Urban Transit Coaches – Maverick (Top Gun), Your Bus is Here... |first=Jim |last=Brophy |date=June 2, 2018 |website=Curbside Classic |access-date=12 September 2022}}</ref>

The arrival of the [[Capstone Turbine]] has led to several hybrid bus designs, starting with HEV-1 by AVS of Chattanooga, Tennessee in 1999, and closely followed by Ebus and ISE Research in California, and [[DesignLine Corporation]] in New Zealand (and later the United States). AVS turbine hybrids were plagued with reliability and quality control problems, resulting in liquidation of AVS in 2003. The most successful design by Designline is now operated in 5 cities in 6 countries, with over 30 buses in operation worldwide, and order for several hundred being delivered to Baltimore, and New York City.

[[Brescia|Brescia Italy]] is using serial hybrid buses powered by microturbines on routes through the historical sections of the city.<ref name="Source">{{cite web |url=http://draft.fgm-amor.at/altermotive/study_sheet.phtml?study_id=2866&lang1=en |title=Serial Hybrid Busses for a Public Transport scheme in Brescia (Italy) |publisher=Draft.fgm-amor.at |access-date=13 August 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120316112717/http://draft.fgm-amor.at/altermotive/study_sheet.phtml?study_id=2866&lang1=en |archive-date=16 March 2012}}</ref>
