The last time the Test Team spent a session with RB4 it was still a race virgin, but this week in Barcelona, it has evolved into a veteran of three grands prix, about to continue its development in preparation for the first European leg of the season. With the championship now underway, testing rules mean that only one car can be used per team. The test lasts for four days, as the rule restricting the test to three has been altered this week to allow teams additional time to evaluate the Bridgestone slick tyres to be used as from the start of 2009. This makes meaningful study of the lap times from the next four days almost impossible as there are no set times for running next year's rubber.

David Coulthard was at the wheel for us today: in the morning he concentrated on general chassis and aerodynamic work and in the afternoon he evaluated the slick tyres. He continues driving tomorrow.
