On the final day of testing at Barcelona, Mark Webber topped the timesheet in his Red Bull RB4.
Red Bull have not shown much form in previous tests and the final day gave a small glimmer of the potential the car has. It was the first time that the car had run with a high engine cover fin and it has proved a successful modification.
Heikki Kovalainen was just four hundredths of a second behind Webber, squeezing his team-mate Hamilton out by three hundredths of a second the McLaren pair look evenly matched and it should prove an interesting season for the young drivers.
Robert Kubica was just behind the two McLarens, showing that the BMW team have definitely overcome the balance issues that marred their first tests BMW look quick enough to challenge the top two teams in the coming season.
Nick Heidfeld was the only driver to bring out a red flag when he span his car early in the morning session.
Once again Honda disappointed with Barrichello finishing in 11th, and Button finishing last behind the Force India of Sutil.
