2026 Barcelona-Catalunya Grand Prix - Barcelona, June 12 - 14

In overtake mode battery cuts completely at 355 km/h, but if you arrive with a lot of momentum and in close slipstream then apparently you can gain an extra 5 km/h with ICE power alone.
Unless this 355 km/h mgu-k limit is lifted then I don't think much higher than 360 kmh is possible.

Momentum does not work like that. If your power cuts off at 355 momentum will not push you further than 355, the acceleration would cease. You would reach "terminal" speed if your drag exceeded force generated by the engine.

The fact that these cars can accelerate above 355 on ICE power means that they are super low drag, which is not unexpected as they know they have cornering modes when they want to corner.

Bortoleto hit 360 km/h at the Barcelona, a new record for this generation of cars!

can we expect 370kmh+ at Baku/Monza/Mexico?

I was told (here) the cars can't accelerate after the electrical engine cuts off. Even though we had reports of cars exceeding these speeds in testing.

In overtake mode you get more power and speed allowance.

Not a good start of week for Spanish F1 and football fans!

Why Spanish F1 fans, PZ?

Alonso and Sainz race results in their home country.

Not over 355kph.

If any car is still accelerating at a decent rate, acceleration doesn't just instantaneously stop. The accelerations will slow, and then the car will slow.

for example get on a highway, floor it, and then let off the gas. unless you are driving an aerodynamic brick or an econo box you will likely see the speed still increase a little before it starts to decrease.

If power is still being applied the car will continue accelerating until terminal velocity.. We haven't seen one of these cars reach terminal velociy yet have we? Let's assume straight mode, no super clipping, in 8th gear and driver keeps it on the pedal.

I'm sure it helps that he was at the back of a train. (scroll right to see the video)

The acceleration will stop as soon as the resulting force is <= 0 (Newton's first law). Bortoleto was only able to accelerate from 355 to 360 because the force created by the ICE was higher than drag, roll resistance etc. The rate of acceleration up to this point is completely irrelevant.

If you let off the gas (or press clutch) you will not see the speed increase, even a tiny bit. It just does not work like that. Acceleration is equal to force (net) divided by mass. Cars have two forces working on it, forward force (tires pushing against the road) and drag and roll resistance. If you let go off the gas your acceleration immediately drops to less then zero (due to drag and resistance).

The acceleration will stop as soon as the resulting force is <= 0 (Newton's first law). Bortoleto was only able to accelerate from 355 to 360 because the force created by the ICE was higher than drag, roll resistance etc. The rate of acceleration up to this point is completely irrelevant.

Thank you.
