The Lancia Aurelia (the first series production car with a V6 engine) was also successful in motor racing. Four of the ''Aurelia B20 Coupes'' were entered in the 1951 [[Mille Miglia]] with the best placed cars finishing second and fourth.<ref>{{cite web |title=1951 ex-Mille Miglia, ex-Le Mans, Lancia Aurelia B20GT |url=https://www.thornleykelham.com/1950-ferrari-195s/1951-mille-miglia-lancia-aurelia-b20gt-series-1/ |website=www.thornleykelham.com}}</ref><ref>{{cite web |title=Mille Miglia - 1951 |url=http://grandprixhistory.org/mille_miglia_1951.htm |website=www.grandprixhistory.org |access-date=25 December 2019}}</ref> A tuned {{convert|3102|cc|cuin|0|abbr=on}} version of the Lancia V6 engine producing was {{convert|230|PS|kW|0|abbr=on|order=flip}} used in the [[Lancia D24]].

The initial version of the [[Ferrari Dino engine]] was a {{convert|1.5|L|cuin|0|abbr=on}} racing engine used in Formula Two racing in the 1957 season. It had a V-angle of 65 degrees and dual overhead camshafts. The Dino V6 underwent several evolutions, including a {{convert|2.4|L|cuin|0|abbr=on}} version used in the 1958 [[Ferrari 246 F1|Ferrari 246]] Formula One racing car.<ref>{{cite web |title=Ferrari 246 F1 |url=https://www.f1technical.net/f1db/cars/116 |website=www.f1technical.net |access-date=14 December 2019}}</ref><ref>{{cite web |url=https://www.allf1.info/engines/ferrari.php |title=Ferrari engines |website=www.allf1.info |archive-url=https://web.archive.org/web/20180531045018/http://www.allf1.info/engines/ferrari.php |archive-date=31 May 2018 |url-status=dead}}</ref> A few years later, the 1961-1964 [[Ferrari 156 F1|Ferrari 156]] Formula One car used a new V6 engine with a V-angle of 120 degrees and a displacement of {{convert|1.5|L|cuin|0|abbr=on}}.<ref>{{cite web |title=Ferrari Dino 156 |url=https://www.f1technical.net/f1db/cars/148 |website=www.f1technical.net |access-date=14 December 2019}}</ref> This engine was shorter and lighter than the Ferrari Dino engine, and the simplicity and low center of gravity of the engine was an advantage in racing. It won a large number of races between {{f1|1961}} and {{f1|1964}}. However, Ferrari's founder had a personal dislike of the 120 degree layout, preferring a 65 degree layout, and after that time it was replaced by other engines.<ref name="Ludvigsen">{{cite book|last=Ludvigsen|first=Karl|title=Classic Racing Engines|publisher=Haynes Publishing| year=2001|isbn=978-1-85960-649-0}}</ref>{{refpage|pages=138–141}} The Dino engine was also used in the [[Lancia Stratos]], which was a highly successful rally car that won the World Rally Championship in 1974, 1975 and 1976.

A notable racing use of the Alfa Romeo V6 engine was the [[Alfa Romeo 155#155 V6 TI|Alfa Romeo 155 V6 TI]], designed for the [[1993 Deutsche Tourenwagen Meisterschaft season|1993 DTM season]] and equipped with a {{convert|2.5|L|cuin|abbr=on}} engine making a peak power of {{convert|490|PS|kW|abbr=on|order=flip}} at 11,900 rpm.

The ''Renault-Gordini CH1'' was a 90 degree V6 engine with an iron block. It was introduced in the 1973 ''Alpine -Renault A440'' sportscar racing car. This engine won the European 2&nbsp;L prototype championship in 1974 and several [[European Formula Two Championship]]s. A turbocharged {{convert|2.0|L|cuin|0|abbr=on}} version was used in the [[Renault Alpine A442]], which won the [[24 Hours of Le Mans]] in 1978.

A turbocharged {{convert|1.5|L|cuin|0|abbr=on}} version of the ''Renault-Gordini CH1'' engine was introduced in the 1977 [[Renault RS01]] Formula One car. Renault struggled with reliability issues in 1977 and 1978; however, the 1979 season saw some good results at a few races. In 1981, the [[Ferrari 126C]] Formula One car used a turbocharged V6 engine.<ref>{{cite web |title=Ferrari 126CK |url=http://www.f1technical.net/f1db/cars/469 |website=www.f1technical.net |access-date=14 December 2019}}</ref> Ferrari won the [[Formula One constructors' championship]] with turbocharged V6 engines in 1982 and 1983. Initial versions used a 120 degree V-angle, before switching to a 90 degree V-angle for the 1987 [[Ferrari F1/87]] racing car. Other successful turbocharged V6 Formula One cars in the era of 1982-1988 were the [[McLaren MP4/2]], [[McLaren MP4/3]], [[McLaren MP4/4]], [[Williams FW10]], [[Williams FW11]], [[Williams FW12]], [[Lotus 95T]], [[Lotus 97T]], [[Lotus 98T]], [[Lotus 99T]] and [[Lotus 100T]].

The [[Nissan GTP ZX-Turbo]] and [[Nissan NPT-90]] competed in the [[IMSA (racing)|IMSA]] sports car prototype category from 1985 to 1994 and used a turbocharged V6 engine loosely based on the Nissan VG30ET production car engine.<ref>{{cite web |title=1989 - 1994 Nissan 300ZX IMSA - Images, Specifications and Information |url=https://www.ultimatecarpage.com/car/5983/Nissan-300ZX-IMSA.html |website=www.ultimatecarpage.com |access-date=26 December 2019}}</ref><ref>{{cite web |title=Steve Millen's IMSA 300ZX and the Dream Season of 1994 |url=https://autoweek.com/article/car-life/steve-millens-imsa-300zx-and-his-dream-season-1994 |website=www.autoweek.com |access-date=26 December 2019 |language=en |date=11 November 2014}}</ref> The [[Nissan 300ZX]] used a similar engine to compete in the 1996-1997 [[All Japan Grand Touring Car Championship]] (now known as the 'Super GT' championship).<ref>{{cite web |title=JGTC 1996 |url=https://www.classicscars.com/wspr/results/jgtc/jgtc1996.html |website=www.classicscars.com |access-date=26 December 2019}}</ref><ref>{{cite web |title=JGTC 1997 |url=https://www.classicscars.com/wspr/results/jgtc/jgtc1997.html |website=www.classicscars.com |access-date=26 December 2019}}</ref>

Downsizing to V6 engines in open-wheeler racing became more common:

* the [[IndyCar Series]] switched to turbocharged V6 engines in 2012.
* the [[GP3 Series]] switched to [[Naturally aspirated engine|naturally aspirated]] V6 engines in 2013.
* the [[Formula One|Formula One World Championship]] switched to turbocharged hybrid V6 engines in 2014.
* the [[FIA Formula 2 Championship]] (formerly known as the GP2 Series) switched to turbocharged V6 engines in 2018.
* the [[FIA Formula 3 Championship]] (created from the merger of the GP3 Series and the FIA Formula 3 European Championship) began using naturally aspirated V6 engines from 2019.
