Last weekend’s Bahrain Grand Prix signalled many things, the ban on refuelling, the return of Michael Schumacher, three new teams making their debut, the dawn of a new points system and the return of Cosworth as an engine supplier.

Teamed up with four teams for 2010, Williams, Lotus, Virgin and HRT, the engine giant was able to leave Sakhir on Sunday afternoon with their first point in the bag when Williams racer Rubens Barrichello finished in tenth place overall.

While the other teams failed to score points with HRT and Virgin failing to see the chequered flag, all due to non engine related issues, both Lotus runners saw the finish and all four teams gave the engine supplier their stamp of approval.

“After the many months of work developing and implementing our return as an engine supplier to Formula One it was good to finally get the racing underway. It was satisfying to see all four of our teams in action and to witness the three new teams enjoy their Formula One debuts,” said Cosworth’s Mark Gallagher.

“From an engine performance point of view, I think we can be very satisfied with the performance of the CA2010 in Bahrain with both AT&T Williams drivers finishing the race with Rubens picking up a championship point for tenth.”

“We have spoken with our technical counterparts in each of the teams on a regular basis to ensure that we are meeting our targets and objectives. I have also spoken to several of the drivers who have given us positive and constructive feedback on the CA2010 performance and driveability.”

“We have accumulated a lot of track data from Bahrain, a circuit that is quite demanding on the engine, and this will be thoroughly examined and analysed by our team of engineers back in Northampton. Overall, it has been a solid start to Cosworth’s 2010 season, in terms of engine performance and reliability.”
