New chassis for Sainz to prevent cooling problems

Difference between two cars

Lando Norris didn't suffer from this and so McLaren was faced with a mystery where the difference between the cars came from. But to be on the safe side, McLaren picked up a new chassis, which is now a race earlier than initially planned.  What has been replaced are different parts, including the monocoque.

In this way McLaren wants to exclude everything and try to find out the specific cause of the problem. It remains to be seen if it will work, because as a compromise McLaren had to make adjustments to the car of Sainz at Silverstone that were not necessarily advantageous. But this prevented overheating somewhat.

So far the Spaniard also has a more difficult season than his teammate Norris. A flat tire in the first Silverstone Grand Prix, cooling problems in the second race and so on. "He hasn't had any control over things like that, but he has lost a lot of points because of that. It's up to us to perform better and hopefully we can do so in Barcelona", said Seidl at the press conference.

Carlos Sainz has a new monocoque this weekend, McLaren team boss Andreas Seidl says, as the team try to get to the bottom of the overheating problems he was suffering at Silverstone. Radiator inlets are part of the monocoque and this is "one reason of many which could cause it"
