The Formula 1 team may have to use the same basic chassis this year, but that didn’t stop expectations for a fairly big car change in 2021.
That’s because, beyond the natural evolution of design, there are some new rules aimed at cutting performance with respect to floor space and other auto parts.
The goal of the change was to reduce downforce by about 10%, including removal of floor space and new restrictions on brake duct and diffuser dimensions.
The rampant advance that the team was making at the forefront of performance was driven by the fact that Pirelli’s tires were under greater stress than ever before.
Improved lap times are associated with the heaviest F1 cars ever, which means the tires had to deal with the greatest force in F1 history.
As seen at last year’s British Grand Prix, it opened the door to a greater risk of tire failure. Silverstone was one of the toughest trucks for cars with such high-speed corners, and the end of the race was hurt by many. Failure.
The only route Pirelli has opened to minimize the risk of repeated tire failures was to mandate a higher minimum tire pressure-although this was great for maintaining tire robustness. I hate teams and drivers because they feel they have to get over it-inflated balloons.
In 2021, there was a risk of gaining benefits that could further exacerbate the tire situation, even if the team had less freedom than usual, as there were no changes to pull back downforce.
Mario Isola, head of F1 and car racing at Pirelli, talked about the need for changes towards the end of last year.
“Obviously, from now until the end of 2021, given that the team has a great deal of ability to develop cars,” he said.
“At the end of 2021, the load level can be very high.
“Therefore, that is the right thing to do, as we are obliged to increase the pressure to the point where deterioration, overheating, or blisters occur again at levels we do not want.”
However, drivers may deny the fact that F1 cars will be slower this year, but a quick look at recent season data shows why the FIA felt it had to deal with it.
Comparing the lap times at Silverstone, it’s clear how fast the car has been due to the consistent track layout over the last period.
The pole position times of the British Grand Prix since the beginning of the turbo hybrid era are as follows.
British Grand Prix pole position time
2014 1 minute 35 seconds 766 seconds
2015 1 minute 32.248 seconds
2016 1 minute 29 seconds 287 seconds
2017 1 minute 26 seconds 600 seconds
2018 1 minute 25.892 seconds
2019 1 minute 25.093 seconds
2020 1 minute 24 seconds 303 seconds
The comparison with 2014 should be made in light of the fact that the qualifying session that afternoon was affected by the humid conditions, but even without it, a fairly surprising level of progress during this period. had.
Without any changes to this year’s aero rules, it was almost certain that the lap time would sink to the 1’23s range. This meant that the tires were even more stressed and strained.
Therefore, it is expected that changes in aero rules related to Pirelli’s harder and tougher tires will reduce enough lap times for F1 and its tire suppliers to have a trouble-free year.
Hard tires are expected to be one second slower per lap, and many technical experts suggest that floor changes will result in a much greater reduction in lap times than originally expected.
However, it will take some time before the 2021 F1 car is unleashed in pre-season testing in Bahrain, so the team will work even harder to regain the lost ground.
Red Bull aims to succeed in returning to last season’s levels.
“The goal is to reach downforce levels at the end of 2020,” explained Red Bull Motorsports Advisor Helmut Marko. “You lose about 20%.”
However, judging from what many teams have found in this winter wind tunnel, it looks like a very difficult order to approach the aggressive lap time improvements seen in recent years.
