F1 2026 Regulations: What is Recharge mode

The 2026 F1 season is seeing the biggest overhaul of the chassis and power unit regulations in the sport's modern history.

The cars are both smaller and lighter and are powered by new power units. The PUs will still be a 1.6-litre V6 turbo hybrid - as they have been since 2014 - but the 2026 versions have seen the emphasis on electrical energy output tripled.

The latest F1 regulations cycle has introduced an almost 50/50 power split between the internal combustion engine (ICE) and the 350kW electrical MGU-K system, after the MGU-H was removed altogether.

This change means drivers now have to turn their attention to a much more advanced form of energy management, with an increased focus on energy recovery through braking and 'super clipping', which was a hot topic of discussion among some of the sport's biggest names at 2026 pre-season testing.

What is F1 Recharge mode?

Naturally, you may be wondering, 'what is super clipping', what is 'Recharge mode' and 'what does lift and coast mean?' Well don't worry, GPFans are here to answer all the questions you may have about the new power units.

Thanks to the new regulations, the energy recovery system (ERS) can now recharge the new battery to power the new hybrid unit with twice as much energy per lap as it could in 2025, with drivers able to recharge it up to 9MJ per lap.

These elements of energy management are often automated and will therefore play a significant role in helping the drivers to manage their battery capacity throughout a lap and across a grand prix distance.

Recharge mode is when a driver refills the battery on their new cars using recovered energy, using a range of strategies to capture the energy and send it back to the battery, something previously referred to as 'harvesting'.

This can be done a number of ways, including through braking, when partly on the throttle, when lifting and coasting or when a driver is super clipping, although the effectiveness of each strategy will depend on the engine map, the circuit profile, and the overall Recharge energy allowance for that circuit, which will vary from track to track.

Most of the time, the Recharge will be automated by use of selectable Recharge maps and targets, which mean braking, part throttle and super clipping will all be automated functions controlled by the engine control unit (ECU).

The only Recharge mode the driver will have control of personally will be the lift-off regen (just another term for lift and coast) which is when a driver lifts off the accelerator early before a braking zone, allowing their car to coast, something which allows the MGU-K to harvest the energy and recharge the battery.

Adopting this tactic will disable the active devices on the new cars, whereas super clipping will allow the active aero to remain open due to the process taking place whilst a driver is still at full throttle.

'Super clipping' is when the cars automatically power from the ICE to redirect it to the battery at various points around the track when a driver is at full throttle, which results in the car automatically slowing down due to the loss of power, particularly to the rear wheels.

The more that any of the above processes take place, the more energy will be available within the car's battery to allow things such as overtake mode to take place. If a driver burns too much energy attacking during a grand prix or through overtaking, they may run out of it later at a vital moment in their race, hence why energy management and recharge will be crucial in 2026.
