Button took the wheel for the first track run of the new MP4-28

The aim for tomorrow afternoon is to conduct a series of longer runs.

The morning’s running was compromised by a mechanical fuel-pump issue, which cost a couple of hours’ track-time, but the problem was quickly rectified and the team was able to run productively for the remainder of the afternoon.

Jenson spent the first part of the day’s programme running a lower-lip rake to complete some aero mapping work. The end of the day saw the team evaluate the effects of a series of mechanical set-up changes, using both the Supersoft and Hard Pirelli tyres.

Both the aero mapping and the balance changes fell in line with the team’s pre-test expectations. Jenson set his fastest time of the day on the Hard compound.

Sergio Perez gets his first opportunity to drive a Vodafone McLaren Mercedes car tomorrow (Wednesday). The knock-on effects of this morning’s fuel-pump issue mean that he will begin his day by continuing today’s initial aero and balance checks.

The aim for tomorrow afternoon is to conduct a series of longer runs – possibly incorporating live pitstops into the mix if the team is satisfied with the day’s initial progress.
