The current aero package, introduced in 2022, was intended to make it easier to follow and hence overtake than under the previous regulations.

That initially proved to be the case but in the third year of car development drivers are reporting dirty air is increasingly becoming an issue and following is becoming harder once more.

Mercedes technical director James Allison you have questioned the focus on controlling wakes in the current rules, calling it a “tilting at windmills type of challenge.”

Encouraging overtaking will again be addressed in the 2026 rules, which are still being debated.

“I don’t think the regulations have failed,” said Vowles when asked by if changes were needed for the last season to the current rules in 2025.

“I think that would be wholeheartedly unfair. I think the competition is pretty tight in the midfield. There is overtaking that takes place.

“I think even on the data that we can see now, it’s still better than the ’21, ’20 generations of cars. But especially the leading pack have developed the car in an extraordinary way that as you develop downforce, it is making it difficult to follow.

“But I still think about all the metrics and all the data we can see, you’re now getting closer than you were before as a result of things, which was an intention behind it.

“Whether they will improve in ’25, no, I don’t think so. There’s no reason to think it will improve next year. And in ’26, again, the rules are still being ratified as we speak, so it’s hard to evaluate that.”

Aston Martin team principal Mike Krack backed Vowles’s view on the current aero regulations.

“I agree with James, I think the regulations are not a fail, at all,” he said. “I think it has allowed various designs from the beginning, then obviously a dominance that none of us want, but that’s a fact.

“But all in all, I think we have one more year to go, and then we welcome the new ones. As James said, they’re not 100% fixed yet, and we look forward to them.

“But honestly, I think the current regulations are well done and well made, and we have had great racing behind one team.”

Krack also stressed that it will be important for the teams to have sight of the 2026 regulations as soon as possible, even if they can’t start aerodynamic work until January 1 2025.

“I think the goal is to have the first set of regulations by the end of June,” he said. “And then we will move from there. Probably they will not be complete or fully complete, but I think it’s important to have regulations early because it’s really a big change for everybody.

“And so we need to see how is the weight target, how is the architecture of the car? What is the tire size? A lot is still being discussed. So we should not delay too much.”
