I didn't fully understand the comment, especially regarding the phrase "active aero open on the straights." The part about high revs is ok. However, the section where the wings open, reducing friction, isn't energy recovery; it's where energy is consumed to generate speed. The section where the wings close, increasing downforce, is energy recovery. Maybe misunderstand ispano6 here. I don't know.
Instead of relying solely on the rear wheel, turning the Ice into a generator is something I think everyone does. In this respect, the new gearbox and the vibration-free, revving engine are promising. Even without the extra horsepower, these two alone would have provided a performance increase. Therefore, I think the horsepower gained with the new Honda Ice is only half the current situation.
It could differ per track layout and what kind of corners come after the straightline. The trade off of not shifting up to 8th to realize top speed is minimized by straightline mode reduced aero drag and parasitic MGUK drag when clipping starts. The confusing aspect of clipping vs harvesting under braking is that you may have maps where even if you lift to coast you may experience a spike in RPMs. Ideally if you could be in neutral gear and rev the engine up to max RPM(like at race starts) without affecting the gradual deceleration from coasting, you'd utilize that kind of map. During harvesting on straights you are at max throttle and when clipping starts the drivetrain could theoretically disengage the rear gearbox such that any rotation of the PU goes directly to the MGUK and instead of engine braking slowing down the car you just coast as efficiently as possible. I'm not saying this is what Honda is exactly doing but there was evidence of this kind of RPM spike behavior in several preseason test runs and at some circuits. Having the lowest numbers in the speed trap may be a choice where the benefit of reaching beyond that speed doesn't pay off as much due to having to brake harder or put more energy into the tyres when attacking a corner. It might be Alonso's tyres in Hungary didn't degrade as much because the car is geared toward efficiency and less delta in corner entry speeds from deceleration. The penalty is not having straightline speed to catch your opponent if you aren't within 1 second behind to use overtake mode. The new chassis should give the AMR26 the ability to catch the car in front through the corners and be able to use overtake mode when it becomes available. Hopefully the team is figuring this out.
Some time ago I've presented this same idea in the 2026 PU thread.
Fuel flow is linked to power demand by the driver (throttle position) as much as it allows, if my memory serves me well, no more than 120kw when off-throttle.
Edit: for maximum recovery, it would be necessary to put neutral or disengage the clutch while pressing the throttle.
The ECU can do whatever it's programming wants...
During superclipping - Imagine the driver is flat through a long straight.
Initially:
Pedal: 100%
Throttle: ~100%
ICE: Maximum permitted torque
MGU-K: +350 kW
As battery energy becomes limited:
Pedal: 100%
Throttle: ~100%
ICE: Same maximum permitted torque
MGU-K: +250 kW
Later:
Pedal: 100%
Throttle: ~100%
ICE: Same maximum permitted torque
MGU-K: 0 kW
The driver is still requesting full power. The ICE is still producing as much torque as the regulations and engine allow. The loss in acceleration comes from reduced electric assistance, not because the throttle closes.
What about harvesting at full throttle?
This is where the 2026 rules are different. The MGU-K is allowed to generate torque (negative torque) even while the driver is at full throttle if the control strategy calls for it. In that case:
ICE torque +700 Nm
MGU-K torque -40 Nm
Wheel torque +660 Nm
The engine itself doesn't have to close the throttle to create that harvesting opportunity. The MGU-K simply applies a small resisting torque, converting some crankshaft power into electrical energy.
