The 8140 was a diesel engine made by Sofim for cars. Originally introduced as a swirl chamber, naturally aspirated diesel it was mostly used in commercial vehicles worldwide.

At the time of introduction, the 8140's overhead camshaft layout (driven by a toothed timingbelt) was unexpected in a diesel engine, which were typically overhead valve designs.{{cite book |year=1977 |chapter=Fiat 131 Mirafiori: da 3 anni è un successo |trans-chapter=Fiat 131 Mirafiori: a three-year success |title=Quattroruote: Tutte le Auto del Mondo 77/78 |language=it |location=Milan |publisher=Editoriale Domus S.p.A |page=205}} Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to restrictions of the original design.{{ cite magazine |last=Norbye |first=Jan |editor-last=Kennett |editor-first=Pat |date=September 1982 |title=Intertruck: Italy |magazine=Truck |location=London, UK |publisher=FF Publishing Ltd |page=27}} Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development. Before entering the market, Fiat tested the Sofim engine in its 131 model during the 1977 London-Sydney Marathon.{{cite web| url = https://www.londonsydney77.com/crews.html | title = The 1977 SIA London to Sydney Marathon: the Longest Car Rally in History | access-date = 2025-02-15 | archive-date = 2024-12-13 | archive-url = https://web.archive.org/web/20241213183728/https://www.londonsydney77.com/crews.html | url-status = live}}

First direct injection models also appeared in the mid-1980s.

Additionally to the Fiat designation 8140 some engines got a Renault tag (S8 for indirect injection, S9 for direct injection).

In the early beginning there was a {{convert|1,995|cc|l|0|adj=on|order=flip}} four-cylinder {{cvt|65|PS}}, called the Sofim 8144.65. Alongside the 2.4-litre version it was used in light commercial vehicles like the Saviem SG2, OM Grinta, and the Fiat/Iveco Daily, as well as passenger cars like the Fiat 131 and 132 models.{{cite web|title=1981 FIAT 131 DIESEL SUPER 2500|url=http://www.automobile-catalog.com/car/1981/713060/fiat_131_diesel_super_2500.html|website=automobile-catalog.com|access-date=2012-01-01|archive-url=https://web.archive.org/web/20160506015656/http://www.automobile-catalog.com/car/1981/713060/fiat_131_diesel_super_2500.html|archive-date=2016-05-06|url-status=dead}}{{cite web|title=FIAT 131 CL DIESEL 2000 (1978)|url=http://www.automobile-catalog.com/auta_details1.php|website=automobile-catalog.com|access-date=2012-01-01|archive-url=https://web.archive.org/web/20120106213704/http://www.automobile-catalog.com/auta_details1.php|archive-date=2012-01-06|url-status=dead}}{{cite book |last = Mazzocchi Bordone| first = Maria Giovanna |title = Fiat, tutti i modelli del novecento| trans-title=Fiat, all the 20th century models| publisher = Editoriale Domus| series = Un secolo di auto italiana | volume = II| location = Rozzano (MI) | date = 2010}}{{rp|96}} It also saw use in the Fiat Campagnola.

{{anchor|Today|F1A|F1C}} F1A/F1C

After continuous development these engines are nowadays known as F1A (2.3 L) and F1C (3.0 L), available for marine and industrial use from Fiat Powertrain Technologies (FPT) and CNH Industrial (since 2012) respectively. The 3-liter version is also built by Mitsubishi Fuso for use in their medium-duty commercials, under the name 4P10.
