McLaren to keep aero upgrades on car after practice trial

McLaren Formula 1 boss Andreas Seidl says that the aero package that the Woking team trialled at Silverstone on Friday worked as intended and will stay on the cars of Carlos Sainz and Lando Norris for the remainder of the weekend.

McLaren to keep aero upgrades on car after practice trial

The team brought a modified floor and front and rear wings for the British GP, aimed in part at improving performance in slower speed corners.

Hot track temperatures and gusty winds made it hard to gather accurate data on the new parts. However, Seidl said the overall verdict was that they made a difference. Sainz was sixth in FP2, although he was flattered by the red flag that spoiled the soft tyre runs of some rivals.

“We had a testing programme that we wanted to get through, so big thanks really also to the entire team for pushing very, very hard back home in the last weeks and month to deliver these upgrades,” he said. 

“We went through the back-to-back tests in FP1, which we could complete. And so far with everything we have analysed the updates work as intended, which is again a good sign that we are heading in the right direction. 

“It's important to have this correlation between what we see back home in the wind tunnel and here on track. At the same time it was not an easy day also, because of these gusty winds.

"It’s not what you really would like to have when you do comparisons like that with accurate measurements, because these steps you make are so small that in an ideal world you want to have consistent laboratory conditions. 

“But nevertheless we got through the programme and then in addition with some changes to the car we made also on the mechanical side for the second session, I think we were in the expected window again, in terms of performance in FP2.”

While the conditions prevented McLaren from fully evaluating the update, Seidl said there is still work to be done on the cars.

“The drivers are still not fully happy with how the car feels, with the balance of the car. 

“But at the same time, we need to be very careful with windy conditions plus the hot track temperatures today that we make the right conclusions for Saturday onwards when we definitely get low temperatures. And hopefully the wind is also calming down a bit. 

“It's definitely not easy also for the drivers to really point out the weaknesses of the car because in the end, the windy conditions override quite a lot.

“But with everything we have seen so far, the updates worked as intended. And that's independent of any conditions, because in the end, it's simply about putting aero load on the car, more downforce.”

Sainz suffered some damage but that will not impact him on Saturday.

“I think he had a small off over running over one kerb which damaged one of the bodywork parts, but it's nothing that is bothering us too much," said Seidl. "We can repair it and then use it again.”

The sliding doors moment that saved Red Bull and Porsche

OPINION: Everything looked set for Red Bull and Porsche to join forces for the 2026 season, before the marriage between both parties was called off. While at the time it looked like a major coup for Formula 1 in gaining both VW Group powerhouses Audi and Porsche for 2026, Red Bull and Porsche have really been spared a potentially fractious relationship.

The difference between Mercedes’ stumble and the fall of F1 giants

OPINION: Mercedes endured its worst season of the hybrid Formula 1 era, but was mercifully spared its first winless campaign in over a decade late on. It has owned up to the mistakes it made which led to its troubled W13. And while its task to return to title-challenging contention is not small, its 2022 season seems more like a blip than the beginning of a downward spiral.

How Red Bull's dynamic leader Mateschitz shaped its F1 philosophy

The death of Dietrich Mateschitz last month has not only deprived Red Bull of its visionary founder, it has shorn Formula 1 of one of its most influential benefactors. Mateschitz himself was famously media-shy, preferring to let the brand do the talking on his behalf. And, while it’s now normal to speak of Red Bull F1 titles and champions made, Mateschitz never assumed it would be easy or even possible – as ANTHONY ROWLINSON discovered during this previously unpublished interview from 2006…
