Cosworth has been an independent engine supplier for many years. In the last weeks it was announced that Williams, one of the three teams the manufacturer provides with engines, will make the jump to Renault. Cosworths Mark Gallegher says that it's disappointing but won't affect the business: "It has been an interesting few weeks as the decision Williams has taken to go with Renault starting next season is, from a human point of view inside Cosworth, disappointing. From a business point of view it doesn’t change anything for us because we had always planned our comeback into Formula One as an engine supplier based around supplying new teams with engines."

"It was actually very fortuitous that a team as famous and successful as Williams came along and asked us for an engine supply. Disappointing on a human level, on a business level we understand the decision and we are just looking to the future now. We have got two new teams that have recently announced big changes. The Marussia Virgin Racing deal with McLaren Applied Technologies is a very interesting one, particularly for us to work with McLaren and Marussia Virgin from next season. Then with the recent changes at Hispania Racing in terms of investment in the team, fresh investment, I think everyone can see HRT has made some good steps this season. Business continues."

He continues: "I think we have been quoted as saying and quite rightly that since 1963 Cosworth has supplied 67 different teams with engines. Actually 10 of the teams on the grid today in some form or other have used our engines in Formula One so I am confident that we will have many good days ahead. The quest for us really is to secure long-term contracts, certainly beyond the V8 era, and with the exciting news of the arrival of the V6 engines for 2014, that’s more of a focus for us at the moment so onwards and upwards."
