Williams to run blown exhausts on Friday

(GMM) Williams will decide whether to race a Red Bull-like blown rear exhaust layout at Silverstone this weekend after Friday's practice sessions.

With official confirmation on Tuesday, the British team will become the third team to emulate on track Red Bull's low-exhaust concept, with engine gases diverted through the double diffuser to boost downforce.

"We'll evaluate the exhaust during the practice sessions on Friday and will make a final decision as to whether we race it that night," said technical director Sam Michael.

In the hands of Finnish test driver Valtteri Bottas, the new package made its debut on the runway at England's Kemble airport on Tuesday.
