Head: Pole gives Williams new impetus

A spectacular performance from Nico Hulkenberg saw the German rookie take pole at Interlagos by over a second in drying conditions. The result was Williams's first pole since Nick Heidfeld started from the front at the Nurburgring in 2005.

"There's no champagne for Saturday, but it's fantastic for the team," Head told the BBC.

"Everybody back at base and here is pushing to try and get back to being a frontrunning team and this will give everybody good impetus."

Head also revealed that Hulkenberg had initially been unsure about changing to slick tyres in Q3, but was persuaded after his veteran team-mate Rubens Barrichello made the switch.

"Rubens changed to dries first, Rubens is very experienced in choice of tyres," Head explained.

"Nico thought it wasn't good enough for dries but his race engineer Tom McCulloch told him Rubens was going onto dries, Nico followed and put the hammer down and really did the job. It's fantastic."
