Hamilton's top speed figures weren't that much impressive. I think it was about 6km/h better than others without DRS. To me it looks he gained on others during whole acceleration phase.
I think it works like this.One and Only wrote: ↑15 Nov 2021, 10:56Still more power requires more energy, especially if you run high downforce configuration.Just_a_fan wrote: ↑15 Nov 2021, 10:40Because the ICE is normally run more conservatively in order to last 7 or 8 races.

It would make sense if they usually run at ~95% of fuel flow limit and then decide to run it at 98% for example. It would be interesting to see how much fuel actually these cars use when driver hits full throttle.
By using more revs. It's high revs that take life out of the engines. The gearing allows for higher top speeds than normal to allow for the higher speeds achieved when in the tow / when DRS is open, so it's just a matter of getting the engines to run at a higher speed when loaded.restless wrote: ↑15 Nov 2021, 10:47The question is not of running harder.Just_a_fan wrote: ↑15 Nov 2021, 10:40Because the ICE is normally run more conservatively in order to last 7 or 8 races.

Its about how they get so much better efficiency with same fuel amount
Revs never change, everyone always drives in 10500-12500 range because of how the rules are written. I've never seen anyone running below these numbers in a deliberate way, even when they are in complete cruise mode (verstappen in mexico for example). Because of that we also know they all run at their maximum fuel flow of 100 kg/h (because regs specify that number from 10500 rpm and up). Therefore engine saving is likely done by reducing turbo pressure, ignition timings and so on.Just_a_fan wrote: ↑15 Nov 2021, 10:40Because the ICE is normally run more conservatively in order to last 7 or 8 races.

I believe it has to be 'available' to all but not compulsoryMtthsMlw wrote: ↑15 Nov 2021, 10:52After the party mode ban you have to run the engine in the same mode (ERS excluded) from the beginning of Quali. Can this mode be set on a driver to driver basis? I vaguely remember that after a certain point one mode must be used by every customer or am I wrong? As far as I understand you can decide on another mode from weekend to weekend though.
That's correct, as anything else would be unfair. If they all had to run the same mode, then all the teams running the PU would be limited by the team with the worst cooling, intake, and exaust package!
Not only unfair, but also illegal afaik. Customer teams must have same options.
All the modes has to be available to all customers. Whether they will use it is another question. And full beans really means full beans.MtthsMlw wrote: ↑15 Nov 2021, 10:52After the party mode ban you have to run the engine in the same mode (ERS excluded) from the beginning of Quali.

They might be available as the regs stipulate that, but you can be sure not everyone uses same modes and they pretty much go with what mercedes tells them to use based on wear and probably a hundred other factors. For example hamilton with his brand new engine most definitely wasn't using same maps even compared to his teammate, let alone all other mercedes PU cars.toraabe wrote: ↑15 Nov 2021, 23:05All the modes has to be available to all customers.

As Lewis stated his tyres were still good after the pass on Max, and he was using them up instead of engine I presume.djones wrote: ↑16 Nov 2021, 12:43I'm not so sure Hamilton has to nurse the engine. If that was the case why did he then clear Max by 10 seconds?
This means they are either super confident the engine will last to the end of the season or they have a strategy to change the engine again at the next race. If it's a track with long straights and a new engine mapped to last 1 race gives an advantage like in Brazil then it's actually a pretty solid idea??
