Formula 1 is no stranger to rule and regulation changes. But calling the new 2026 regulations a change is a colossal understatement. It makes the introduction of Hybrid power units in 2014 look minute in comparison. The 2026 regulations are a transformation. The biggest thing to hit motorsport since asphalt. Here is what you need to know.
Let’s start with the aero. Gone are the ground-effect cars, the days of porpoising, and running millimetres off the ground. The 2026 cars will also be smaller. Slightly shorter, a bit narrower, and lighter means that they’ll be a bit nimbler and a bit more responsive. They’ve achieved this through shortening the wheelbase slightly. From initial (sneaky) shots of some 2026 cars, out on ‘marketing’ runs, it appears that the higher ride heights of a few years ago will be making a comeback. The new cars will also run on significantly simpler floors. It does mean less downforce, but also translates to a more adaptable setup window for the car. Naturally, this is all relative to car performance in relation to the rest of the grid.
Staying on aero, both the front and rear wings have been simplified in terms of design. The front wing in particular will be slightly narrower, with the endplates becoming a critical area for development throughout the season. There will be no more rear beam wings either. Simple right? That’s until you learn that active aero is being reintroduced to F1. In 2026, the cars will have an adjustable front and rear wing, which will be used only in certain parts of a given track. In other words, the ‘flaps’ will remain closed in the corners to maintain grip while they can activate low-drag mode on designated straights. Importantly, and unlike the now departed DRS, this will be available to every driver on every lap.
There will still be a benefit of being within one second of the car ahead, though. Instead of DRS, drivers will now have Overtake Mode, not to be confused with Boost Mode (more on that later). Overtake Mode will give a driver extra electrical energy to aid overtaking. In the past, drivers have been able to activate a mode that gave them max power from the engine and battery to either defend or attack with. This, in 2026, will be known as the Boost button. For your information, drivers will also be in charge (no pun intended) of the battery recharge. There will be different modes available to recharge the battery from braking and engine energy. To ensure this recharge the ERS (Energy Recovery System) can now recharge the battery.
Naturally, this means that the power unit, too, has undergone significant changes. It’s still a 1.6-litre V6 turbo hybrid, but the output produced by the internal combustion engine has been reduced. Instead, the electric motor’s output has been tripled, which means
that there is a 50-50 split between internal combustion and electric power. The MGU-H (heat recovery system) has been scrapped, which accounts for the slightly lighter car. But that’s not all. For the first time ever, Formula 1 will be running on 100% sustainable fuel.
The 2026 regulations are a revolution the likes of which Formula 1 has never seen. With this, there is no form book, no way whatsoever to predict any semblance of a pecking order.
