Sergio Perez has explained how the high temperatures in Hungary today affected the balance of his car, causing him to struggle in the second free practice session for the race this weekend.
The Mexican driver could only come home 12th in FP2, over one second behind pacesetter Sebastian Vettel, but he explained in a post-race interview how the heat had a detrimental impact on the pace of the MP4-28 car.
“I think this morning was very good, the car really worked fine. Unfortunately this afternoon the balance changed a lot,” Perez said.
“With the increase of track temperature it really made a difference, a big impact. The compounds are behaving so different in the prime to option.”
Perez’s final point was echoed by Pirelli’s motorsport director Paul Hembery, who identified a 1.5 second gap between the tire compounds after practice.
