The pre-race press conference will be switched from Thursday to Friday, ahead of the first and second practice sessions, while cars will now be in parc ferme conditions from the start of FP3, which also marks the point at which the teams must return their cars to the ‘reference specification’ presented for scrutineering before FP1, so any bodywork trialled in practice must be removed. There will also be small but significant changes to the race weekend structure, which will be condensed to improve the fan experience and help teams deal with an expanded calendar, with the maximum number of races in a season now 25. However, it excludes marketing costs, the salaries of drivers, and of the top three personnel at any team. The cost cap is being set at $175m per team, per year, and applies to anything that covers on-track performance. Tyre blankets, meanwhile, will not be scrapped as once proposed, instead remaining for 20, albeit with restrictions. Gearbox design will be more restricted, with configurations frozen to save research and development costs. As a result, the F1 has said that the cars will be 25 kg heavier as a result of the new tyres, changes in chassis and PU materials. There will also be the introduction of certain standardised parts, such as fuel pumps, parts that must have a prescribed design, such as wheel covers, and there will increase restrictions on the number of times some components, like brake pads, can be replaced. In a further bid to reduce aero development costs, the number of wind tunnel runs teams can do each week has been slashed, with emphasis put on using CFD (Computational Fluid Dynamics) simulations over physical ones. Rules have been put in place to limit car upgrades over race weekends, and the number of in-season aero upgrades, reducing the costly development arms race that can result in a less competitive grid. ![]() ![]() Regulations regarding the power units consequently remain the same as now, but exhaust systems have been added to the list of PU components that are limited in number per season, with each driver able to use six before penalty.įor the first time ever, Formula 1 will introduce spending restrictions to make the sport fairer and more sustainable with the intention of ending the growing spending gap between F1’s big spenders and those with fewer resources, and the on-track performance differential this brings. However, with the 2021 car design, this drops to around 5-10%, with airflow coming off the new cars both cleaner and directed higher, meaning it has significantly less impact on drivers following, giving them the chance not just to overtake, but to battle.įormula 1 initially wanted to include changes to the power unit and increase the number of standardised components, but ultimately compromised, respecting the fact that the engine manufacturers have invested a huge amount in the development of the existing hybrid engine. Running in dirty air behind another car, a 2019 machine could lose more than 40% downforce. One of the goals was to find a solution to the loss of downforce that the current cars experience when running in another car’s wake. A tyre with a stiffer side wall doesn’t move as much, simplifying the aerodynamics and thus reducing development investment.Īlthough aesthetics was a major consideration, the changes outlined above aren’t just cosmetic – over several years, both Formula 1 and the FIA have been working tirelessly to design cars that can race more closely. The teams with the biggest budgets are able to look at these effects in detail and are better able to deliver solutions that give them an edge over others. The high-profile tyres currently used in F1 tend to move around and deflect a great deal, which has an impact on aerodynamics. The switch to low-profile tyres isn’t purely aesthetic, says F1. ![]() It’s also proposed that the wheel rims will be fitted with a rotating LED display panel to provide information to spectators, while a bodywork display panel is also proposed for the same reason. ![]() In principal, the 2021 F1 cars will have a radical new design philosophy and striking new look with sweeping bodywork, simplified front wings, bigger rear wings, increased underbody aerodynamics, wheel wake control devices, simplified suspension and low-profile tyres with 18-inch rims. After months of negotiations, F1 made the long-awaited announcement on 31 October that the new regulations for the 2021 season have been unanimously approved, the World Motor Sport Council revealing all 10 teams, the FIA and FOM have come to an agreement over them.
