Cosworth has revealed its 2014 Formula 1 power unit although it will not be used this season.

The English company started work on a 2014 engine as long ago as 2010, when the regulations stipulated an I4 layout at the behest of Volkswagen. But when the German company decided against a Formula 1 entry in June 2011 the rules were switched to a V6 layout. Cosworth decided around this time that without a backer for the V6 that it could not offer it as a customer engine.

According to sources in Cosworth speaking with Racecar Engineering founder Ian Bamsey, now editor of Race Engine Technology magazine, development on both the I4 and V6 has continued as the former is being worked on for an undisclosed high performance road car project and the latter so that when it gains the required support it is ready to re-enter Formula 1. Honda, Ferrari, Mercedes and Renault are building 2014 engines, whilst the PURE project faltered early on.



The full story of the engines development and performance simulation can be read in a fascinating piece in Race Engine Technology.
