Editing V10 engine (section)

=== Motor racing ===
One of the first known V10 engines designed for motor racing was a {{convert|3.5|L|cuin|0|abbr=on}} prototype [[Formula One car|Formula One]] engine built by [[Alfa Romeo]] in 1986.<ref name="velocetoday.com">{{cite web |title=Alfa V10 164 Pro Car |url=http://velocetoday.com/cars/cars_134.php |website=www.velocetoday.com |access-date=27 January 2020}}</ref> Originally intended for the [[Equipe Ligier#Formula One|Ligier]] Formula One team, this partnership collapsed without the engine being used in any races. Alfa Romeo fitted the engine to two [[Alfa Romeo 164#Concept cars and variants|Alfa Romeo 164 Pro Car]] prototypes in 1988, however these cars also did not compete in any races.<ref name="velocetoday.com"/>

The most widespread use of V10 racing engines has been in Formula One. Following a ban on turbocharged engines after 1988, the first V10 Formula One cars were the 1989 [[McLaren MP4/5]] and [[Williams FW12]]. V10 engines were used by the majority of teams by the [[1996 Formula One World Championship|1996 season]], following reduction in displacement from {{convert|3.5|to|3.0|L|cuin|0|abbr=on}}. The V10 seemed the best compromise between the lower weight of a V8 and the higher power of a V12. [[Renault F1]] used a flatter 110° angle in [[2002 Formula One season|2002]] and [[2003 Formula One season|2003]], but reverted to a more conventional 72° following the change in rules which dictated that an engine must last two race weekends. In a further change to the rules, V10s were banned for the [[2006 Formula One season|2006 season]] onwards in favor of 2.4 L V8s.

In sports car racing, the first V10 engine was used by the [[Peugeot 905]] in the two final races of the [[1990 World Sportscar Championship season|1990 season]]. This was followed by the [[Judd (engine)#GV10|Judd GV10 engine]] being used by several teams during the [[1991 World Sportscar Championship|1991 season]] and the [[Toyota TS010]] that debuted in the last race of the season. The [[Audi R15 TDI]] was a [[Le Mans Prototype]] (LMP) racing car that used a turbocharged diesel V10 engine and competed in various endurance races in 2009 and 2010. The [[Audi R15 TDI]] set the current distance record for the [[2010 24 Hours of Le Mans]].<ref>{{Cite web|title=Flashback: Le Mans 2010 and the distance record|url=https://www.audi-mediacenter.com:443/en/press-releases/flashback-le-mans-2010-and-the-distance-record-3550|access-date=2021-05-22|website=Audi MediaCenter|language=en}}</ref>
