Sainz still suffering with overheating issues in Spanish GP Practice

McLaren Racing’s Carlos Sainz was still suffering with overheating issues in Free Practice for the Formula 1 Spanish Grand Prix.

Sainz struggled with overheating in last week’s 70th Anniversary Grand Prix at Silverstone, and was hoping to get on top of the problems in Spain in order to avoid having to continue to run with more cooling on his McLaren MCL35.

He was 11th fastest in Free Practice one and managed to improve to seventh in the second session, setting a best time of 1m18.214s, but while that may sound encouraging, Sainz confirmed after both sessions that he was still struggling with overheating an has been unable to resolve the issue.

“We tried a couple of test items and mainly tried to understand the overheating issue we had in my car over the last weekend.” commented Sainz.

“Unfortunately, the problem is still there and costing lap-time, so we’ll keep investigating in order to take the best decision.

“Apart from that, performance-wise, the car wasn’t too bad today.

“There are still a few changes to make for tomorrow, but the main focus point now is still the cooling.”

McLaren Racing Director Andrea Stella added that the hot temperatures in Barcelona made it difficult for cooling and tyre temperatures and that there is still a difference in the temperatures between Sainz’s car and Lando Norris’.

“We’ve had a productive Friday and have been able to work through all our planned test items and improve our understanding of the balance of the car, the level of grip and the tyres.” said Stella.

“The temperature in August is, of course, hotter than we’re used to in Barcelona for the race, and that creates some particular challenges for cooling and tyre temperature.

“We still see the split of temperatures across cars and we will make further changes tomorrow in order to resolve this anomaly.

“On the tyre side, it looks like the behaviour is more typical that what we saw in Silverstone, where we suffered with some issues.

“We know that when the track is windy, our car becomes a bit temperamental – but we’ll try to extract the most out of it tomorrow and be fighting for Q3 to give us the best chance of good points on Sunday.”
