Ahead of their partnership for 2007, Williams will use Toyota engines for the first time at the Silverstone test next week.
The presently Cosworth-powered outfit plans to run a Toyota V8 in the rear of a modified ‘FW28’ chassis, with current test driver and 2007 racer Alex Wurz at the wheel.
In other developments, it is reported that Michael Ammermuller will appear for Red Bull at this week’s Jerez session, as the German rookie properly tests a F1 car for the first time.
It is expected that, ahead of a possible ‘Friday’ drive for Red Bull or Toro Rosso in China and beyond, he will collect the requisite mileage to apply for a Super License.
Ferrari is scheduled to test at Fiorano.
