F1 is switching to 18-inch wheels next year which will be around 9% taller, their diameters growing from 660mm to 720mm. Williams gave us the best of both worlds with their launch, showing a livery on a show car in the morning and then hitting the track with the real thing in the afternoon. Much like rivals Red Bull, Mercedes' new car is expected to evolve significantly over the six days of testing before the Bahrain Grand Prix on March 20. Like Nascar teams. We don't have to wait for another six months to see it, but this prototype is missing its wheels. MacLeod (@macleod) 3rd November 2021, 8:10. Smaller fuel tank requires the re-introduction of refuelling. The reason for the change is the benign quality of downforce generated in ground effect. This is no bad thing, given that theyre already the most advanced and most efficient engines on the planet. Shorter races mean less chance to see some action. F1 is moving towards fuels with lower energy density @jerejj if you reduce fuel capacity in addition to that reduced energy density F1 would indeed be having only short races. Formula One F1 British Grand Prix Silverstone Circuit, Silverstone, Britain July 15, 2021 The new 2022 F1 car is unveiled during a promotional photoshoot REUTERS/Andrew Couldridge, So now one would wonder, Well, why does it appear bigger anyway?. But one thing that fans wouldve noticed is that along with being more smooth on the eye (and hopefully for racing as well), the 2022 car looks bigger compared to the 2021 car. But then, when you're celebrating a new $500 million deal, why not? DAVID TREMAYNE: Grosjeans shocking accident will only spur efforts for even greater F1 safety. I think F3 cars are faster than FE, but FE never races on a track where times can be compared. So it was no surprise that the launch video for the AT03 spent as much time focusing on the garments being modelled by drivers Pierre Gasly and Yuki Tsunoda as it did on the car itself. Notice the words Im using options and available. Making the cars smaller wont reduce the weight significantly. That may still be the case with refuelling, but having additional options available makes more outcomes available, even if they arent used. So why not give them the option to alter their weight (fuel load) and stint length with a relative performance benefit for more stops as they wish? Make them heavier!

The running tyre pressures are also likely to be lower because the smaller sidewall on the 18-inch tyre makes it more robust, so teams have a whole new set of parameters to deal with - on top of the physical differences in the tyres themselves. Got a potential story, tip or enquiry? The FIA isn't saying how much smaller the cars will be in four years' time besides proclaiming that it wants to "reduce car dimensions." "Or, you can turn in too early, hit the inside wall in 15 and then hit that kerb. One of the biggest challenges for young drivers in recent years has been a lack of opportunities to drive F1 cars in order to try and prove themselves worthy of a seat, with strict limits on testing in between the race calendar. If they go with All Wheel Drive and movable aero therell be no point watching for anything the drivers do, because they certainly wont be having much influence. Those differences are much bigger from 2022 onwards, with the benchmark team who get 100% of the allocated time now the team in seventh place. "We believe in the car dimensions there lies an opportunity. Drivers: Lando Norris and Daniel Ricciardo.
