Heikki took over testing duties from Gary Paffett today, with the Finn running alongside teammate Lewis Hamilton. Work for the Vodafone McLaren Mercedes drivers focused on continued tyre work with Bridgestone and aerodynamic and mechanical developments. The pair also spent time on practice starts in the pitlane. Lewis's programme ended just over an hour before the end of the session with a minor transmission issue.
