Editing Cosworth DFV (section)

==Background==
In 1965, the [[Fédération Internationale de l'Automobile]], that administered [[Formula One]] racing, agreed to raise the series' maximum engine capacity from {{convert|1.5|L|cuin|0}} to {{convert|3.0|L|cuin|0}} from 1966. Up until that point, [[Colin Chapman]]'s successful [[Team Lotus]] cars had relied on power from fast revving [[Coventry Climax]] engines, but with the change in regulations Coventry Climax decided for business reasons not to develop a large capacity engine.

Chapman approached [[Keith Duckworth]], previously a gearbox engineer at Lotus but now running his fledgling [[Cosworth]] company with [[Mike Costin]], who commented that he could produce a competitive three-litre engine, given a development budget of £100,000.<ref name=atlasF1 />

Chapman approached the [[Ford Motor Company]] and [[David Brown (entrepreneur)|David Brown]] of [[Aston Martin]] for funding, each without initial success. Chapman then approached Ford of Britain's public relations chief, former journalist [[Walter Hayes]], with whom he had developed a close working relationship from the early 1960s. Since Hayes had joined Ford in 1962 the pair had previously collaborated in the production of the successful [[Lotus Cortina]], introduced in 1963.<ref name=atlasF1>{{cite web|last= Ludvigsen |first= Karl |author-link= Karl Ludvigsen |year= 2007 |url= http://atlasf1.autosport.com/2001/jan10/ludvigsen.html |title= Walter Hayes: Racing's Ultimate Insider |work= Atlas F1}}</ref> Hayes arranged dinner for Chapman with Ford employee [[Harley Copp]], a British-based American engineer who had backed and engineered Ford's successful entry into [[NASCAR]] in the 1950s.<ref name=atlasF1 /> Hayes and Copp developed a business plan, which was backed by Ford UK's new chairman [[Stanley Gillen]], and approved by Ford's Detroit head office as a two-part plan:

*Stage one would produce a four-cylinder [[Cosworth#The FVA series|FVA]] twin-cam engine for [[Formula Two]]
*Stage two would produce a [[V8 engine]] for Formula One, by May 1967
