Beginner path · Step 5F1 2026 rules explained: Boost, Overtake Mode, Active Aero
2026 brought one of the biggest rule changes in F1 history. If you learned the sport from older Drive to Survive seasons, some of what you know no longer applies. Here’s what changed.
1. New engines: half electric
The power units are still 1.6-litre V6 turbo hybrids, but the balance has shifted. About half the power is now electrical. The electric motor (the MGU-K) is now almost three times as powerful, at around 350 kW. A complex part called the MGU-H was removed, and the engine runs on 100% sustainable fuel.
Why you’ll notice: drivers now have to manage their battery all lap. You’ll see cars lift off early before corners to recharge. You may also see sudden speed differences on straights, because one car has energy left and another doesn’t.
2. Smaller, lighter cars
The cars are shorter (wheelbase down 200 mm), narrower (down 100 mm) and about 30 kg lighter, with less downforce. They should be nimbler and better at following each other.
3. Active Aero (goodbye DRS)
The front and rear wing flaps now move:
- Corner Mode: flaps closed for grip in the corners (the default).
- Straight Mode: flaps open on designated straights to cut drag and raise top speed.
Unlike the old DRS, every driver can use Straight Mode in the zones, not just the car chasing within a second.
4. Overtake Mode: the new passing aid
If you’re within one second of the car ahead at a detection point (usually near the final corner), you unlock extra electrical energy for the next lap. The car ahead’s electrical deployment also tapers off at very high speeds. That combination helps the chasing car close in.
5. Boost and Recharge
- Boost: a button that deploys stored battery energy whenever the driver chooses, for attack or defence, anywhere on the lap.
- Recharge: harvesting energy from braking and lifting off. Most of this is automated, but how a driver manages it is now a real skill.
What it means for watching
Overtakes can now happen in unusual places. A driver with more battery can pounce at a corner where passing used to be almost impossible. Listen for engineers talking about “energy” on team radio. It’s the new tyre management.

FAQ
Does F1 still have DRS in 2026?
No. DRS was used from 2011 to 2025. It has been replaced by Active Aero, which every driver can use on designated straights, and Overtake Mode, which gives extra electrical energy to a car within one second of the one ahead.
What is the difference between Boost and Overtake Mode?
Boost can be used anywhere, at any time, as long as the battery has charge. Overtake Mode is only unlocked when a driver is within one second of the car ahead at a detection point, and it gives extra energy for the following lap.
Are 2026 F1 cars electric?
They are hybrids. Roughly half the power comes from the electric motor and half from a V6 turbo engine running 100% sustainable fuel.
