Only Red Bull and Williams take to the track on the first day in Jerez

The two Red Bull RB4s of David Coulthard and Mark Webber occupied the top two positions in today's timesheet at Jerez, with the Williams FW30s of Kazuki Nakajima and Nico Rosberg following closely behind.

The four drivers were the only ones involved on the track, waiting for all the remaining teams (with the exception of Ferrari and Toyota) to join the collective testing from tomorrow. It should be noted that Williams has tested a new front wing attachment system, after the problems encountered in the previous test session
