Sebastian Vettel followed on from where team-mate Mark Webber left off yesterday, topping the timesheets at the Circuit de Catalunya.
The impressive reliability of the RB7 was again demonstrated as the world champion completed 112 laps in Barcelona as his team concentrated on both long and short runs, and completed a series of pit stop practices.
“It was a good day and a good time, although to be honest, it's difficult to say where we are, as the lap times of the teams are all over the place,” said Vettel. “We've done a lot of laps again today, which is good.
“We have had no major problems with reliability throughout testing and the speed looks good as far as we can judge, but I think we have to wait until after Melbourne – maybe in Malaysia or China – to really see where we are.”
“It was good to have the race team here yesterday and today, to go through pit stop practices,” added Head of Race Engineering Ian Morgan. “Normally, we would do that once in pre-season testing but, as we lost a little time with the weather at the last test, this extra test was a good opportunity to get some more practice in ahead of Melbourne.
“As for the rest of today's programme, it was much the same as yesterday. Seb did 112 laps without any real problems all day, which is gratifying. It's always difficult though, to tell what your true position is until you start the season, but our pace looks good at the moment, which is promising.”
