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.

Idle sound means nothing. Honda runs the car on half cylinders in the pits before firing all 6 at exit. We don't know why they run it as such, whether it be a trick firing order or layout or just something to hide audible details from opponents. It's all speculative and has been discussed in length in this thread over the last 12-18 months.
It sounds different however, but I wouldn't mind hearing it at full chat. Here's hoping there's another tweet soon.

:roll:

It sounds perfectly normal. If you doubt it, listen to the new Ferrari engine on the Sauber:

They tend to hide car until launch

Ah, thanks for that, I thought I could hear something that was different to the others. Doesn't sound too shabby while running. Also IT"S RUNNING!!!! Fingers crossed for them.

Is it me or is there a weird sound on upshift? Is it a vibration?

The mercedes upshift, is just totally clean but if you listen to the Honda, there's a kind of stuttering of the revs at each upshift. What do people make of that?

Here's the sound in Australia 2017 free practice.

Sounds much worse in this video but it's definitely the same vibration on upshift.
