Honda Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Sector 1 is the main reason the pace is really slow.

Yes, we heard you. Stop milking it for the umptieth time. This is a huge improvement compared to earlier this year. Unless McLaren wants to be saddled with Sainz's PU they better quiet down a bit on Honda shaming.

I'm stating the truth based on the times I saw on the live timing, no need to be ultra defensive about this. Sector 2 and 3 are fine, sector 1 is not (in race pace, in quali is good with a tow and slightly not ok without).

Vandoorne's speed in race mode is terrible, not even 300 km/h.

The others are about 310 km/h.
I was following Alonso's long run towards end of FP2, as he was behind Vettel. I think Vettel might have been getting a tow from Verstappen in some of these laps. I'm assuming Alonso was too far away to benefit in the last few laps.

Vmax delta to Vettel on the straights before some of these corners (actual speed of Alonso in brackets):

-10 kph Variante del rettifilio (varied from 307 - 314 km/h)
-5 kph Variante della roggia (299 km/h)
-10 kph Variante Ascari (308 km/h)
-6 kph Curva Parabolica (311 km/h)

I remember earlier on in the season when McLaren were a whopping 25 km/h slower than Ferrari on Vmax in races and against some Merc customer PU cars. Surely this is a massive improvement?

Race pace during these laps were in the high 26s, which is not very competitive though.
That's not good, race pace needs to be low 26's to have point scoring pace.

Some encouraging signs on-track today and based on the info. posted from autosportforum. Power is an easy concept to grasp so the term is used freely but it's becoming more and more clear that power isn't the real problem. We see this with single lap pace in the top 10 even on challenging circuits. Fuel efficiency and sustaining deployment are the biggest problem. If the super-elusive Spec. 4 addresses efficiency along with adding power, it's completely plausible they start matching or beating Red Bull with the current Renault engine.

I just found this, it's a video of Alonso's 8th time today:

(video of video... but still).

To be honest, that data doesn't look bad.

Today showed us how much time Honda has gained this season. And many more updates are still to come according to Hasegawa. I am really confident of Honda being able to make this work. They can surpass Renault this season, maybe McLaren can even battle Red Bull at some circuits. Finally, Honda shows they got their --- together. And I rate their potential much higher than I rate Renault's potential. Honda started this project later, had only 2 cars to acquire data, and didn't have experience in F1 for years when they returned in 2015. Yet, reliability is at the same level, and performance difference is "only" 40 HP if rumours are to be believed. That's not too bad.. not good, but not bad either.

Honda says the spec 3.7 has brought over a tenth, so that's good news.

I believe it was a tenth in Spa, right? Probably it's even more in Monza. Good news either way, but I'm really curious to see the performance spec4 will bring.

Will the two fatso and Alonso wait till then? that's the big question.

So that's what .3 since Austria? If true it means they could be under a second from pole in Singapore.

McLaren already made their decision, they want to switch to Renault, but nobody knows if it will happen.

Albert Fabrega says Honda had a "qualy mode map" for Spa and now it can be used at race too. It's worth 25hp...
