McLaren believes the teams have regained lost performance

McLaren technical director James Key believes most teams will regain lost performance due to a rule change ahead of this season and that there is still a lot of potential in the current rules. Ahead of a major rule change for 2022, the FIA ​​and Formula 1 have introduced several minor changes for 2021 that include reduced floor dimensions in front of the rear wheels, shorter diffuser bulkheads, and limited brake cooling suction dimensions.

The changes were supposed to lead to a loss of about 10% downforce, but as the teams have been working on the new concept for months they have managed to make up for most of the losses that were initially huge. “The changes had an effect in the sense that they stopped the rapid development of these cars and that’s what we needed for this extra year with these rules,” Key said.


"But there's still a lot of development potential on the rest of the car." "My estimate is that by the beginning of the season, most will make up for all the losses. Whether it's the first specification of the car or someone else, it's hard to say, but I don't think they have recovered 100% yet.

" "Our first specification was somewhat successful, and the first racing specification, which is still in the definition process, will make up for another part." “So at the moment I can’t give you the numbers in terms of where we will be in the first race.

But it's a few percent difference, not 110% [of last year's performance], so to speak. " "It was a real challenge that required new thinking because the geometries imposed by the rules are unique and we haven't encountered them in the past."

"These changes take your downforce from the rear and force you to reduce some downforce and forward to balance the car so it's a global reduction in downforce." The return of lost performance should mean that this year's cars will be just as fast in a circle as last year, but to be slower, Pirelli made sure that after two years of using the same tires, they prepared a firmer and heavier specification of their tires, which should be about a second slower per lap and which drivers tried out late last year.

The reason is the fact that Pirelli's tires from 2019 were harder and harder to cope with the increasing loads placed on them by the faster cars from 2020, which led to overheating and bursting of tires at the Grand Prix of Great Britain.
