Williams, Toyota and Lexus
That Williams are about to sign a two-year deal with a one-year extension option with Toyota is no surprise, and absolutely no disrespect is meant to Cosworth with that statement, either, for the Northampton company has produced a jewel of an engine in the CA2006, which is a unit truly worthy of a world-class chassis.
Ultra high-revving, compact and produced at about quarter the price of work's engines, the Alex Hitzinger-designed V8 had powered Williams' FW28 chassis to fastest laps and front-row starts, whilst the only thing which kept Mark Webber off the Monaco podium was the failure of a (non-Cosworth) heat shield. So why change from what you know to what you don't?
Simply because Sir Frank is a thoroughly canny fellow, one whose team won no less than nine world championships through their ability to think outside of the box, and he is hoping that Toyota can deliver a thoroughly useful component Cosworth is unable to supply, at least in its present incarnation.
