McLaren: It was a productive day 19 February, 2013 Sergio Perez (MEX) McLaren MP4-28 The second of Formula 1’s three pre-season Spanish tests kicked off today at Barcelona’s Circuit de Catalunya, an aero-dependent track that will provide teams with a clearer idea of the state of their preparations ahead of the 2013 season. Sergio Perez kicked off the running this morning, his second outing behind the wheel of MP4-28. As at last week’s test at Jerez, the team spent the morning running through a series of aero tests before breaking to reset the car for some set-up comparison work. After lunch, Sergio began a series of longer runs to evaluate the effects of the mechanical set-up changes. He also took the opportunity to more fully acclimatise himself to the cockpit controls and team communications that he will start to encounter in the races. The afternoon concluded with a live pitstop practice. It was a productive day. What’s next? Sergio concludes his running. Jenson takes over for Thursday and Friday.
