Editing Straight-five engine (section)

=== Diesel engines ===
The 1938 [[Lancia 3Ro#Lancia 3Ro|Lancia 3Ro]] trucks introduced a straight-five diesel engine to replace the previous straight-three engine. Built for the Italian and German armed forces during World War II and later for civilian usage, the truck remained in production until 1950.<ref>{{cite book|title=Storia Illustrata del Camion Italiano|date=1996 |publisher=Edizione Neri|isbn=978-88-900 955-8-0|language=it}}</ref>

The first mass-production straight-five passenger car engine was the 1974 [[Mercedes-Benz OM617 engine|Mercedes-Benz OM617]], a [[naturally aspirated engine|naturally-aspirated]] {{convert|3.0|L|cuin|0|abbr=on}} engine introduced in the ''Mercedes-Benz 300D (W114/W115)'' models. In 1978, a [[turbocharger|turbocharged]] version was introduced in the ''Mercedes-Benz 300SD Turbo'' models. Mercedes-Benz continued to produce straight-five engines for the next 28 years, until the [[Mercedes-Benz OM647 engine|Mercedes-Benz OM647]] engine ended production in 2006.

In 1978, the [[List of discontinued Volkswagen Group diesel engines#2.0 R5 D 51kW|Audi 2.0 R5 D]] engine was introduced in the ''Audi 100'' sedan. In 1983, a turbocharged version was introduced, initially for the U.S. market Audi 100. Several Volvo cars were produced with Audi straight-five diesel engines, prior to the introduction of the [[Volvo D5 engine|Volvo D5]] turbo-diesel engine; this engine was produced from 2001 to 2017 and was used in several diesel hybrid applications (marketed as "twin engine" models).<ref>{{cite web |url=http://ipaper.ipapercms.dk/Volvocars/GB/V60GBen/ |title=V60_GBen |publisher=Ipaper.ipapercms.dk |access-date=2018-05-17 |archive-date=2018-09-16 |archive-url=https://web.archive.org/web/20180916154704/http://ipaper.ipapercms.dk/Volvocars/GB/V60GBen/ |url-status=dead }}</ref><ref>{{cite web|url=https://www.matthewsvolvosite.com/history-volvo-5-cylinder/|title = History of the Volvo 5 Cylinder|date = 11 October 2017}}</ref>
