Their highest top speed is not only down to having the biggest and most consistent downforce from all the cars on the grid that allows them to crank the rear wing less or the slippiest car out there. It`s also down to MGU-H mapping which is set to harvest energy more than other engine manufacturers by converting more time fuel to electricity. Simple as that! And this is done only at strategic times such as qualy and overtaking&defending.AR3-GP wrote: ↑01 Apr 2023, 22:39The advantage isn't coming from just the MGU-K braking. Honda's advantage is also about the MGU-H recovery which passes to the battery. I cannot find the article yet, but it was explained that Honda made a choice to sacrifice peak power of the ICE, in order to have better MGU-H performance (or something to that effect).gandharva wrote: ↑01 Apr 2023, 22:33There is nothing unique about it. Honda has developed an MGUK that allows it to recover greater amounts of energy in a very short time than its competitors. This has been confirmed by telemetry data already. Where other teams run dry at the end of the lap, the Honda engine still has battery juice left. But this comes at a price: drivability. That's why Max is always on the radio with his engineer about the downshifts. They fine tune the mappings/settings for the car's energy recovery.vorticism wrote: ↑01 Apr 2023, 19:16If this is occurring, what are they doing that is unique in terms of driveline braking? Whether by the engine or the MGUK.
Engine braking would imply something unique within the engine itself. However most of the primary engine geometry is identical for all of the engine suppliers. MGUK operates through the crankshaft and only supplies ~1/5 of overall power.
If these mappings, which are presumably very aggressive, are not tuned perfectly, there will be drivability problems under braking and this might lead to a driver becoming insecure and prone to making mistakes. I think that's what we saw with Perez this weekend.

Then later at a certain phase of the race when they are in the lead it needs to take a lift and cost phase. Yeah, it`s not efficient fuel management but this allows them to have more electric energy throughout a lap that`s why they are clipping last on the straights.
