@ 3:12, does that sound like more than average rev matching?

It sounds like harvesting?

Sounds a bit puny but it's probably just me.

Of course, they are extracting all that is available in the 200ms of gear change allowed by the ruleset.

If they wanted, the downshifts would be a lot faster, as they were since ages ago. Only reason I see to slow down the gearchanges is to, effectively, partially accelerate the ICE while slowing it down with the MGUK.

It could be something as simple as cylinder deactivation as the note seems to be skipping down a notch at some instant.
Or simply strategies to improve turbo speed control for the corner exit (playing with wastegate angle, overrun)? One of the big things back in the MGUH era was corner exist driveability achieved by rev-matching the MGUH/turbo to a certain ICE RPM, not always the same for all corners, to give the smoothest power delivery.

Confident ‘no doubts’ verdict delivered on red bull ford powertrain:

— Racing Bulls boss Alan Permane expressed unwavering confidence in Red Bull's new in-house Formula 1 powertrain, developed in collaboration with Ford. Speaking to media, Permane emphasized:

“We have high hopes, not even hopes, we are sure the powertrain will be good, we are sure it will be powerful, we are sure it will be reliable, so we don’t have any doubts.”

For context: this was an interview with Permane before the '25 Abu Dhabi GP.

I wonder if Racing Bulls and Red Bull were testing different engine specifications. The Racing Bull sounds a lot different and much louder than the Red Bull.

I also think Exxon is a top tier fuel supplier - along with Shell they've decades of experience and tens of billions in R&D into synth fuel that the others just can't match.

Perhaps not a coincidence?

ExxonMobil and Porsche are testing advanced biofuels and renewable, lower-carbon eFuels, as part of a new agreement to find pathways toward potential future consumer adoption. The specially-formulated Esso Renewable Racing Fuel will be tested on the racetrack in Porsche’s high-performance motorsports engines beginning at the Porsche Mobil 1 Supercup 2021 (PMSC). The first iteration of Esso Renewable Racing Fuel is a blend of primarily advanced biofuels. The second iteration will transition to eFuel as early as 2022.

Interesting find. Exxon and Shell have been the leaders in this space for a long time. I think the ICE side of the RBPT PU will be strong. The place where they'll probably start behind is optimizing deployment and recharge on the MGU-K. There's no substitute for actual track time there and it will take a season to build a model for each track and fine tune the map.

Judging by Ben Hodgkinson's comments the efficiency on the K side is pretty much 99%, and the power is obviously capped. It's on the ICE side that performance will differ between manufacturers. If you have a good ICE the rest can be solved with software optimisation in season.

Oh I'm sure the K is efficient but the software that optimizes its usage needs data to work and Red Bull just won't have what Mercedes, Ferrari and maybe even Honda have already built up over the years in this regard. My prediction is the RBPT engine will be able to match the best from Mercedes and Ferrari over 1 qualifying lap because peak potential will be in the same ballpark but this pace will fade in the race because they will find it difficult to match how Mercedes and Ferrari are able to optimize their energy management over the race until they build up enough data to improve their own algos.

AI will generate the most optimum generate and deploy map.

I work in engineering and while AI might be able to crunch a lot of situations relatively quickly, it will not generate the most optimum anything without human intervention.

It certaintly doesn’t work like that.
