The FIA will limit the level of power that F1 cars can generate as part of multiple strict safety rules in the new 2026 regulations, according to reports. With drivers potentially reaching up to 248mph on what will be the fastest grid in the sport’s long history, restrictions will be in place on two tracks to keep speeds under control.
In the 2026 season, the electrical system in F1 cars will almost triple the energy used from 120kw this year to 350kw, which could produce around 475 brake horsepower. At full power, after combining with 540 to 580 bhp from the internal combustion engine, cars could generate significantly in excess of 1,000 bhp.
According to Auto Motor und Sport, the 11 teams set to be on the grid in 2026 have been directed towards a chart ahead of the new regulations.
It displays how much of each track on the calendar drivers could theoretically race at full throttle.
But the FIA intends to introduce reduced power modes named ‘Rev1 mode’ to maintain safety for the Monaco and Singapore Grands Prix.
It will be available to all drivers in both standard and override mode, while they can utilise full power at each of the remaining circuits.

The report adds that the FIA will also introduce limits on the amount of energy that can be stored in the car’s battery every weekend.
At 12 of the 24 tracks – including the new Madrid venue, Spa and Suzuka – a total of nine megajoules of energy is available across practice and qualifying. Up to 8.5MJ can be captured in races.
The figures will differ based on the track. For example, in Jeddah, there will be 8.5MJ of energy available in practice, 6.5MJ in qualifying and 8.0MJ on race day.
Another rule change involves the reduction in combustion engine power on fast tracks such as Silverstone, Monza, Las Vegas and Jeddah.
The reduction will be slashed to 50kW from 100kW, which will lower the chance of a car suddenly slowing on a main straight.
There is also an incoming tweak regarding override mode, which will only be permitted in one place per lap, like DRS.
The FIA continues to take steps to protect drivers while attempting to retain the excitement of racing.
