In addition to the fact that they used to collaborate well enough in the Great Circle a few years back – as well as the lower costs for F1 power plants and the fact that Cosworth will be allowed to work on their units during the 2010 season – Williams admitted he also chose the British engine manufacturer for logistic issues.
“We've finished our contract with Toyota and we've moved on to a British engine manufacturer Cosworth with whom we have won many world championships in the past. They are 50 miles away from Williams which is very convenient,” said Williams, according to the Gulf News daily.
Also, Williams's need of independence also counted a lot in his decision to switch engine suppliers, as he revealed “we will be not under the influence, not that Toyota ever bossed around, but we've just gone a private and independent route.”
In addition to confirming their new engine partners, Williams also revealed that his team will officially announce their 2010 lineup first thing Monday morning. Also, he hinted that departed Nico Rosberg will drive a Mercedes-powered car next year, only he didn't mentioned which one (Brawn or McLaren).
“There are a few things going on at Williams for next season, with our engines, so we thought we can do better. Nico is German and Mercedes need at least one German driver to sit before their engine,” added the boss of the Grove-based organization.
