The focus of today’s running was to bed in a new power unit, which had been slightly updated from last week’s to move closer to the specification scheduled to run at the first grand prix in Melbourne. Much of the day’s programme concentrated on engine mode and driveability tests, tyre compound assessments as well as aerodynamic set-up changes.
A technical glitch halted running just before the lunch break, when an electronics issue caused the car to lose telemetry data. This was identified and reset over lunch and Fernando returned to the track shortly after 15:00.
Despite some niggles in the afternoon as the new power unit bedded into the chassis, today’s run programme was concluded successfully, and Fernando completed a total of 93 laps.
Tomorrow, Jenson Button will once again take over the driving duties as the team continues the MP4-31 test programme.
