Mercedes technical boss, James Allison has described the aero rules introduced this season as "regulatory vandalism".

As if F1 bosses don't have enough to worry about, what with the continuing uncertainty over the pandemic, which, despite their insistence, still looks likely to play havoc with the race schedule as the season progresses, there is the question of what will happen next Sunday afternoon.

On the back of testing, everyone is salivating at the thought of Mercedes and Red Bull finally going head-to-head on a regular basis, hopefully with the likes of McLaren snapping at their heels.

Should the Black Arrows claim the front row on Saturday however, then go on to dominate the podium 24 hours later, there is no doubt that alarm bells will be ringing in F1 Towers, for ahead of a season which will see a number of teams carry out little or no development, the likelihood of Lewis Hamilton and his team claiming another brace of titles may well force even some of the big guns to switch their entire focus to 2022 feeling that 2021 is a foregone conclusion.

Though the cars have been carried over, in yet another bid to reign-in Mercedes' dominance - albeit in the name of cost control and a fear of rising speeds - a number of regulation changes have been introduced.

Among these is a freeze on numerous components including the gearbox, a number of mechanical components and impact structures, while a token system has been devised to permit a very limited number of modifications in accordance to each team's specific needs as well as a limit on engine upgrades.

Meanwhile, aero regulation changes include the simplification of the floor ahead of the rear tyres, and the diffuser, in a bid to moderate the increase of downforce between 2020 and 2021.

Mercedes technical boss, James Allison has described the aero rule changes as "regulatory vandalism".

"In 2020, we saw that the cars were starting to get a little bit too fast for the tracks and a little bit too fast for the tyres," he said. "So, it was important just to bring the performance back a little bit.

"On the back of the car, on the floor, the rules were changed quite a lot," je continues. "It doesn't look like much when you see the changes in geometry terms - look at the car, it won't look so different - but, actually, from an aerodynamicist's point of view, the changes at the back of the car, in front of the rear wheels, in the diffuser behind, in the forward part of the floor, those changes are actually very, very big.

"From an aerodynamicist's point of view, they sort of represent a sort of regulatory vandalism that actually knocked the performance of the car right back, about a year and a half, to somewhere around 2019 levels.

"Of course, we don't want to leave the performance at 2019 levels, the regulators didn't expect them to stay at 2019 levels, they expected us to do our job," he adds.

"We've had a very exciting time in the wind tunnel doing just that, finding new ways to make sure that, even with the floor chopped and hacked by regulations, we're able to put a car down on track that has high performance."

"The entire hybrid era is vandalism

Tyres designed to fall to bits after 20 laps

Drs just wrong

Teams not allowed to test so they can't get better so we have 7 years of domination

No point watching testing as they limit engine miles and tyres

Some race tracks we go to because not because they the good tracks

Made sport so expensive we have few teams and the teams we have are protected by close shop "

"This year tires weight more, I heard by about a pound and a half but don't take my word for it. Also that the added weight was due to increased strength."

"I can't directly answer your question but my understanding is that they didn't want to invest a lot in the tyres due to the big change coming when they go to 18 inch wheels... or whatever the size will be. So, they kick the teams bakl by percentage X, knowing that the teams will recover most, if not all of X during the season, the end result being that speeds aren't much faster than 2020. As opposed to doing nothing where the speeds and loads would expect to push their tyres beyond a safe level.

Added to which they wanted to make some improvements in the aero wake so cars could follow each other more closely. I seem to remember that it wasn't supposed to be as big an improvement as expected for next year but a 20% improvement... or some such figure.

All of this is from my memory.... which isn't what it once was :-) In the end the proof of the pudding is in the eating...we shall see next weekend!

"I am at something of a loss to understand the basis of all of these regulatory changes. The changes were brought in, I believe, based on the proposed safety aspect of the tyres and whether or not they would go the distance safely. We now see that the teams have been able to regain almost the entire amount of downforce lost stemming from those changes. So now the cars are back at almost the same level as in '20. Where does that leave the safety requirements? Maybe I'm missing something here but if not then how can the expenses incurred be justified?"
