Fierce rivals for the 2021 Formula 1 season, Red Bull and Mercedes have finally found a common denominator. The technical directive issued by the FIA (International Automobile Federation) on Thursday (16), which aims to reduce porpoising on cars for safety reasons, united both Christian Horner and Toto Wolff in the criticism made to the movement, in which both believe that the measure is difficult to regulate.

This weekend in Montreal, the FIA intends to collect as much data as possible to find a way to introduce a metric based on the vertical acceleration of the car that will give an acceptable quantitative limit for vertical oscillations and all teams will have to meet this number by setting up their cars accordingly.

Horner gave his opinion on the issue and believes that the FIA will have a hard time finding a suitable result for the measure. "It needs to be discussed a bit more in order to understand how it will be done. Although I believe it is well-intentioned, the correct implementation of the measure is essential. What if, for example, we have a change in weather conditions? I think that's always going to be the big difficulty," said the Red Bull boss.

It is well known that Red Bull is suffering little from the kicks, after all, it leads the Drivers' World Cup with Max Verstappen and the Constructors' with a good gap ahead of second-placed Ferrari, so Christian thinks that the so-called technical directive was issued under pressure. "The implementation and understanding of the metrics are important, but I believe that yes, it was a reaction on them, which was inevitable for safety reasons."

Against this backdrop, the response to the quips made in this way was better than the minimum height, in Horner's view. "I think it would be grossly unfair to have the equivalent of a regulation change in the middle of the year," he added.

Mercedes is the team that suffers the most from porpoising this season, since even heptime champion Lewis Hamilton complained of back pain at the last race in Baku. Toto Wolff, then, went along with his rival's lines and points out that the FIA overcomplicated the situation and that the FIA needed to have had more conversations with the teams. "It's not easy to create this metric, the frequency of measurement can lead to very controversial situations or evaluations. Would a car that is bouncing too much be disqualified? I doubt it. I think all teams need to get together with the FIA and say 'what can we do' to control this."

Wolff followed unison to Horner's statements about the evaluations of the jumps being dubious and interpretive. "The point is: the cars jump at various stages over the course of the weekend, with fuel, without fuel, with wind, headwind, tailwind, distinct levels of grip. I think it is very different to say during practice that you are jumping too much, and then how does it look in the race? What needs to be recognized is that ground effect cars are a problem. And we need to deal with that," added the Mercedes boss.
