Honda Power Unit Hardware & Software

He's not wrong even with the same tires if you compare McLaren to last year's Mercedes they are pretty much even.

At least some of that is down to aero and chassis evolution.

As someone else pointed out, the '2015' was added by the interviewer.
Honda has recently been comparing it's development to Mercedes but comparing from the start of development NOT from the first race it appeared in.

Jenson talked about losing out to other cars in the middle of the staights.

ERS is sorted they say, but what would cause to lose out in te middle of the straights?

[PhillipM]

Outright ICE power once the ERS start harvesting - probably tied to the fuel consumption issues.

mclaren running too much drag, only a few teams with the mercedes powered teams that ran monkey wing and a steep rear wing. TR and redbull did not.

I suspect the turbo's higher backpressure is limiting the ICE during self sustaining mode. This what i am trying to explain for some time now, matching others in peak power and a full lap op ERS deployment is just not enough.

So the answer to their deficit is to get more efficiency from the turbine in blow down mode? The simplest, but not easiest way to do this would be to increase the density of the exhaust gases. Honda compensates by using more exhaust volume, the caveat being that it requires more fuel to achieve?

T1 button was wheel spinning out of the corner and Ham wasnt. Even a slight traction deficit would show up as the car behind coming past in the middle of the straight.

But tbh it could be down to loads of other things as well.

I STRONGLY disagree but respect your opinion.

I think i does not explain, why they "run out of steam" midway on the staights.
If the car is very draggy, would that have more effect on top speed, instead on acceleration?

i think one good example is the works renault f1 team and redbull team both running same renault engine but generally the redbull has better top speed and better acceleration compared to renault f1 team. redbull chassis is very aero efficient and produce better mechanical grip thus getting better acceleration in this respect compared to renault f1.

I think it is more to do with mechanical grip, than with aero drag.

Mclaren is struggling with traction, but is that due to the chassis or with mapping/driveablility of the engine?

its safe to say in the example i mention above renault F1 and redbull , the suspension and aero setting of redbull chassis, are helping to get this acceleration from out of corners on to the straights when compared to renautf1.

It could be those but Slow corners seems to be one of the McLaren's Strengths. I've said this before, still think it's cause they run so little downforce. They do that cause of lack of power. In my opinion the easiest way to see that is by looking at how little rear wing they run. They only team that comes close to running as little rear wing is STR.
