After David Coulthard had two days in the cockpit of the new 2008 contender (one at Jerez last week and another yesterday here in Valencia), today it was Mark Webber's turn to try RB4 for the first time.
After making adjustments to his seat and driving position, Webber got down to business and the car ran almost faultlessly all day. The Australian got acclimatised to what will be his home for this year's eighteen races and, apart from the usual development work, he also did some aero testing with generally positive results.
"I'm happy with the new car," said Mark Webber at the end of the session. "Today has been encouraging and, so far, it seems to be a big step forward from last year in terms of reliability and speed, which is great. Now we need to work with what we've got and get it as fast as possible before Melbourne. We've got a big four weeks coming up."
Webber continues driving tomorrow for the last day of this test.
