Programme: Lewis joined the test this morning as the team began working through a series of pitstop practices. The morning session was spent introducing Lewis to the new aero package and setting up the car to his liking. That work continued into the afternoon, with the team focusing on longer runs and additional pitstop practices. Running was hampered by an off at Turn Two at mid-afternoon: Lewis lost the car at the exit of the second corner and hit a tyre-barrier, which broke off a front-wing endplate and damaged the nose struts. After some repairs to the front-end, he was able to complete the remainder of the session.
Driver for day four: Lewis
Duration of test: Four days (March 9-12)
