WilliamsF1 and Cosworth today announced a wide-ranging partnership agreement for the provision and development of V8 engines for WilliamsF1's entry in the Formula One World Championship.

The partnership is not based on a traditional engine supply agreement; both WilliamsF1 and Cosworth will invest in the programme, underlining both parties' commitment to success. Moreover, the scope of the collaboration includes not just the engine as an isolated element of a race car, but extends to a complete programme of design and development of the entire drivetrain package (spanning engine, transmission, associated electronics, software and installation architecture).

WilliamsF1 has conducted a thorough assessment of the various partnership options available for next season and has been delighted to conclude that the depth of Cosworth knowledge and expertise in V8 development clearly presents the most competitive opportunity for the team and its sponsors. Cosworth is well advanced in the development of its Formula One V8 engine, having routinely exceeded 20,000 rpm during dyno testing since April 2005 at its Northampton headquarters.

The two British companies which are separated by 36 miles, both have distinguished pedigrees in their respective spheres. Together they aim to put British excellence at the front of the Formula One grid next season.

On the announcement of the partnership agreement, Frank Williams, WilliamsF1's Team Principal said, "Cosworth is a leading global authority on V8 engine technology. Next year is a brand new start for all concerned given 16 years of V10 engines. Some teams and manufacturers have absolutely no experience of V8s while others enjoy only limited experience. Cosworth, however, have excelled both historically, as well as in contemporary V8-powered international motorsport. The evidence of Cosworth's V8 progress we have seen so far validates completely the expectation we have of enjoying a class-leading package given next season's engine rule changes."

Tim Routsis, Cosworth's CEO reflected, “Our experience and track record with V8 engines is unrivalled and we are naturally delighted to be alongside one of the most uncompromising and pure-spirited teams in Formula One. We have been working on the development of next year's V8 since April 2004 and right from the onset, our performance targets have been set very aggressively. We are confident that our blue-chip partnership with WilliamsF1 can augment the record of winning the championship every decade since the 1960s. We have developed the 2006 Cosworth V8-CA engine with nothing but front-running success in mind for both the near and long-term. The involvement of Cosworth's sister company, Pi, has been instrumental in achieving this outcome."

Patrick Head, WilliamsF1's Director of Engineering said, "Williams has made this partnership decision purely on technical merit. Among the range of options we considered, Cosworth are very well advanced with existing development and are committed to taking the potential of this collaboration further. Our engineers have already reflected on the very productive and highly motivated nature of the relationship between our two organisations. We speak the same racing language and both have something to prove next year and there can be no greater motivation to succeed."
