Actuator problem loses Pérez full hour
12 October 2012 – Sergio Pérez was deprived of just under a full, crucial hour of running time thanks to a faulty actuator during second practice for the Korean Grand Prix. Having first lost use of his DRS, the McLaren-bound Mexican pulled over in the middle sector.
“I just had no engine power anymore and had to stop on the track,” he explained. “That was why I could not complete my programme and haven’t done any long runs on either tyre compound yet, so it is too early to say what we can do here. Nevertheless, I am very confident for the remainder of the weekend.”
Pérez was still classified 15th as team-mate Kamui Kobayashi – fresh from his Suzuka podium finish – ended the day just one place ahead.
