McLaren: Day spent acclimatising Sergio to his new office 6 February, 2013 Sergio Perez McLaren MP4-28 McLaren report on the second day of Formula 1 testing at Jerez, in Spain. After yesterday’s encouraging start, today’s focus switched to preparing Sergio for his first run behind the wheel of a Vodafone McLaren Mercedes. The morning kicked off with a continuation of yesterday’s aero calibration work, carried out across a number of shorter runs. Attention then turned towards acclimatising Sergio to his new office, running through a prescribed programme of mechanical and aerodynamic adjustments with MP4-28 to give him a greater understanding of the inherent feel of the car and the way it reacts to set-up changes. The acclimatisation session continued throughout the afternoon, concluding in a number of longer runs. Sergio racked up 81 laps – a positive start to his Vodafone McLaren Mercedes career. What’s next Jenson returns for his second and final day of Jerez testing, continuing the aero and mechanical work that has been established over the past two days.
