2025/2026 Hybrid Powerunit speculation

And yes, in 2026, F1 cars will recover energy during cornering by using the MGU-K unit to turn the car's inertia into electricity. And also yes, in 2026 formula 1 engine maps will increase engine revs during harvesting in corners, even with the driver of the throttle, to maximize energy recovery.

And also 'yes', this mode, recovering energy while cornering (with the MGU-H removed) is new for 2026.

I calculated the minimum rpm needed to get the maximum fuel flow values from 5.4.5

I ask, again, how?

The engine maps will control the fuel flow based on various inputs, but they are not allowed to change rpm unless the driver demands more power.

The CPU is also not allowed to automatically change the gears.

Gear changes must be commanded by the driver.

The CPU can reject a shift if it will overrev the engine or will cause the engine to stall, otherwise it has to change gear within a set period after the command (200ms upshift, 300ms downshift).

Also, can you cite your source for this?

[wuzak]

. . . It seems these recovery when cornering are new, meaning this mode was not there before.

As shown by Wuzak above - there is NO MENTION of harvesting "during cornering" in the Technical Regulations. The Technical Regulations do mention harvesting in "partial load".

Actually, the rules do not specify when harvesting/recovery can occur, other than reducing the output of the MGUK from positive (deploying) to negative (harvesting) when at full driver power demand.

The rules do specify limits to the fuel flow at part throttle, which, I assume, is to limit the amount of power that can be recovered by fuel burning.

The rules do not forbid energy recovery in different situations either.

nonsense !
the car's inertia cannot be turned into anything unless the car's speed is thereby reduced (by rear wheel effects only)
