The '''Ferrari Colombo engine''' is a [[Petrol engine|petrol fueled]], [[Water cooling (engines)|water cooled]], [[Carburetor|carburetted]] 60° [[V12 engine]] designed by [[Gioacchino Colombo]] and produced in numerous iterations by Italian automaker [[Ferrari]] between 1947 and 1988. The maker's first homegrown engine, its linear successor is the [[Ferrari Lampredi engine|Lampredi V12]],<ref name="fcom">{{cite web|url=https://auto.ferrari.com/en_EN/sports-cars-models/past-models/125-s/|title=Ferrari 125 S|website=ferrari.com|access-date=11 July 2019}}</ref> which it far outlived, the last Lampredi being made in 1959.

Colombo, who had previously designed [[Alfa Romeo]]s for [[Enzo Ferrari]], placed bore centres at 90&nbsp;mm apart, allowing for significant expansion. Displacements ranged from the diminutive {{cvt|1497|cc|L CID|1}} debut that powered the [[Ferrari 125 S|125S]] racer to the {{cvt|4943|cc|L CID|1}} unit in the 1986 [[Ferrari 412|412i]] [[grand tourer]]. Significant updates were made in 1963 for the [[Ferrari 330|330 series]], featuring a redesigned block with wider, 94&nbsp;mm, bore spacing.<ref name="330gt">{{cite web|url=http://auto.ferrari.com/en_EN/sports-cars-models/past-models/330-gt-22/|title=Ferrari 330 GT 2+2|publisher=Ferrari|access-date=16 June 2015}}</ref><ref name="330gt-2">{{cite web|url=http://www.hemmings.com/hmn/stories/2014/09/01/hmn_feature6.html|title=1964 Ferrari 330 GT|first=Terry|last=Shea|work=Hemmings Motor News|publisher= [[American City Business Journals]]|date=September 2014|access-date=16 June 2015}}</ref>

Enzo Ferrari had long admired the V12 engines of [[Packard]], [[Auto Union]], and [[Alfa Romeo]]<ref>{{cite book|title=Ferrari: A Complete Guide to All Models | last = Acerbi | first=Leonardo|year=2006|publisher=Motorbooks |isbn=9780760325506|page=5}}</ref> (where he was long employed), but his first car, the 1940 [[Auto Avio Costruzioni 815]], used a [[Fiat]] derived [[straight-8]]. Development of the V12 Colombo engine continued long after Colombo had been replaced by [[Aurelio Lampredi]] as the company's marquee engine designer. Although the Lampredi V12 was a real force for the company, it was Colombo's engine which powered Ferrari to the forefront of high-performance automobiles through the 1950s and 1960s.
