Under Fiat ownership, Abarth became the Fiat Group's racing department, managed by engine designer [[Aurelio Lampredi]].<ref name="history" /> Abarth prepared Fiat's rally cars, including the [[Fiat 124 Sport Spider|Fiat 124 Abarth Rally]] and [[Fiat 131#Motorsport|131 Abarth]].<ref name="history"/>
In December 1977, in advance of the 1978 racing season, the beforehand competing Abarth and [[Lancia#Lancia in motorsport|Squadra Corse Lancia]] factory racing operations were merged by Fiat into a single entity named EASA (''Ente per l'Attività Sportiva Automobilistica'', Organization for Car Sports Racing Activities).<ref name="lastampa EASA">{{cite news |url=http://www.archiviolastampa.it/component/option,com_lastampa/task,search/mod,libera/action,viewer/Itemid,3/page,17/articleid,1099_01_1977_0277_0018_16066498/ |title=Rally, Fiat e Lancia si uniscono in un nuovo "super-squadrone" |first=Michele |last=Fenu |date=6 December 1977 |newspaper=[[La Stampa]] |page=17 |access-date=13 March 2015}}</ref> [[Cesare Fiorio]] (previously in charge of the Lancia rally team) was appointed director, while [[Daniele Audetto]] was [[sporting director]]; the EASA headquarters were set up in Abarth's Corso Marche (Turin) offices.<ref name="lastampa EASA" />
The combined racing department developed the [[Lancia Montecarlo#Montecarlo Turbo|Lancia Beta Montecarlo Turbo]] [[Group 5 (racing)|Group 5]] racing car which won the [[1980 World Championship for Makes]] and the [[1981 World Endurance Championship of Makes]]. It also created the [[Lancia Rally 037]] [[Group B]] rally car, which won for Lancia the [[1983 World Rally Championship season|1983]] [[List of World Rally Championship Manufacturers' champions|World Manufacturers' Championship]]).

On 1 October 1981, Abarth & C. ceased to exist, and was replaced by Fiat Auto Gestione Sportiva, a division of the parent company specialised in the management of racing programmes that would remain in operation through to the end of 1999, when it changed to Fiat Auto Corse S.p.A. <!-- changed specialized to BE to match programme -->

Some commercial models built by Fiat or its subsidiaries [[Lancia]] and [[Autobianchi]] were co-branded Abarth, including the [[Autobianchi A112 Abarth]], a lightweight and inexpensive "[[boy racer]]". The A112 Abarth was introduced with a 58 hp engine, soon followed by a 70 hp one, and a specific "A112 Abarth trophy" was run from 1977 to 1984.<ref>{{cite web |url=https://www.fcaheritage.com/it-it/heritage/storie/autobianchi-a112-abarth-58-hp |title=Autobianchi A112 Abarth 58 HP |author=<!--Not stated--> |date=2020-01-14 |website=FCA Heritage |publisher=[[Fiat Chrysler Automobiles|FCA]] }}</ref>

In the 1980s, Abarth name was mainly used to mark performance cars, such as the [[Fiat Ritmo]] Abarth 125/130 TC.

In 2000s, Fiat used the Abarth brand to designate a trim/model level, as in the [[Fiat Stilo]] Abarth.
