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.

Fernando is exaggerating as usual. GP2 engine remember?

My italian sources say Honda is over the 900hp threshold in qualifying. Maybe 905hp.

Andy cowell has confirmed that Mercedes are not close to 1000hp yet. Even after next year's upgrades.

Another source of mine puts Mercedes 970hp in qualifying. Which is ties in to Cowell' statement.

So honda is actaully about 60hp down in Q and maybe 80hp in the race? But nowhere as much as 100hp as Alonso claims.

You have to be very naive to listen to Alonso on these issues.

Actually Alonso does not claim that, he did not even say that. The correct meaning of his statement (or better said, the journalist's transcription of what he said) was explained a few pages back.

I remember Ross Brawn saying that when he started working at Honda the engine group and the chassis group were pretty much "at war" and that the engine side didn't know they were about 50 hp behind Ferrari, they believed the chassis was too draggy.
Sounds familiar

I posted this in the Mercedes engine forum, I wonder, how much does the MGU-K affect the chassis under braking and corner entry. I wonder if part of the Mercedes advantage lies in having to rely less on the MGU-K for harvesting, which allows for a more natural feel under braking. In other words, how much does the driveablity of the power unit influence how hard the car is to drive?



This onboard lap is very telling since driveability is so important for entry and corner exit.

Interesting question. I think the good drivers are skilled enough to drive a car with poor harvesting without much trouble but only that the limit is on a knife edge.
Alonso could easily handle the ferrari in 2014. But kimi had some issues on corner exit. But as you can see it was not harvesting that caused thosw spinout but the power delivery.

Yeah i know the harvesting can does affect power delivery but this happens mostly in lift and coast situations.
The other time when the harvesting is highest is under braking. But then again this is a time of minimal power delievery.

I just did a quick frame by frame comparison against Hamilton's pole lap.

Alonso loses around half a tenth on the first back straight, and another half a tenth on the second back straight. That's all.

That the McLaren Honda is relatively close to Mercedes as far as peak power is concerned. But it could be down to a lot of things, such as drag, downforce level. Sure the car is there more or less in a straight line, but where is it on corner entry? Where is it on corner exit, and fast transitions that require careful throttle application? In the constant throttle high speed stuff they're fine, it's when the car tries to put down power that it has problems. Two things put the power to the ground, the suspension maintaining the contact patch, and the power train. The differentials, transmission, and power plant all have to work together to create a smooth delivery of power to the chassis. It is difficult when the power plant doesn't have a broad usable power band but a smaller, albeit powerful one. It creates instability mid corner as power builds up suddenly, after that there's little the suspension or chassis can do.

A logical band aid would be to try to give the drivers more throttle precision to mitigate power loss on transitions.

Regardless in Spa they would get mauled in sectors 1 & 3 and only hold off the Williams under braking and in sector 2. In Monza they were nowhere, in Mexico and Suzuka they were nowhere. What do these tracks have in common? Power, and traction sensitive corners. In stop and go tracks they were pretty decent, in tracks with lots of constant throttle high speed stuff they were alright. I think they were better in Silverstone than it appeared, Alonso made a mistake but could have easily been in the top 10.

They have the opportunity to torque fill with the KERS to cover up power spikes, but i'm not sure how much battery capacity is available for them to do that consistently.
For Sure!!

The fuel consumption will be important,

last seasons Mercedes was able to run the race with less kg

Hi Wazarisan

So are other engine teams and Honda using this setup now? How much of the MP4 do you get to test the engine on?

Also what is the reason in your opinion that only the Mercedes works team is using a water intercooler while the others have not tried it. Even McLaren in 2014 did not try it.
If a water intercooler is adopted with the Honda engine by the team does it offer any added to the chassis an engine.
Ferrari solution in 2015 was compact and neatly packaged, but was it undersized or the reason it was changed was only to accommodate the VLIM

Can someone point out the battery pack in this below picture, Is it under the section of the ripped floor just ahead of the plank?
Is the silver casting that of the engine or gearbox?

Regarding the water intercooler. Force India said in a RET, that they were not using it due to weight issues.
