MGU-K must be within the survival cell.

I actually think that with narrower cars, greater attention is being paid to keeping the CoG low at all costs. This wasn't a top priority for the tanks of recent years, but now it's becoming much more important again. What I'm missing is the oil reservoir and the compressor...could Honda have placed the oil reservoir at the rear like Ferrari did in 2014? In general, it looks like a split turbo design with no compressor and no oil reservoir.

If they want a low CoG, they should locate the MGUK beside the crankshaft and use the lower part of the fuel tank for fuel.

Rules state in front of engine and same shaft as the crank

what's the two things sticking out....? I thought it was twin throttle body set-up but like since like eons f1 cars where always individual throlle trumpets wasn't it?

The two "horns" on the upper side are also striking. "The horn-like bulges are necessary because a standardised boost pressure sensor is required so that the FIA can monitor the maximum boost pressure," explains Kakuda. "For demonstration purposes, we mounted it where it is clearly visible."

I think the rules are clunky and the place to exhibit technology is in endurance racing, not a single seater, sprint formula series.

Even though most people think F1 should be a technological pioneer.

Why the hell do they monitor boost, when there's already fuel flow limit.

I suppose, to avoid "dieselization" (compression ignition). Why, I don't know, but all the past regs were enforcing spark ignition.

Who are “most people”?

Technological pioneer but they’ve banned turbo technology that has been around 50 years…

Does anyone care to speculate about what is being hidden here?

Honda throws cold water on the-race's absurd claims of lacklustre battery tech.

When it comes to the battery, is it fair to think that the performance advantage from the previous PU can be carried over?
“That’s what we believe—and what we hope. Even after the decision to end our activities, battery development continued, not limited to F1 alone. Because of that, it has evolved further, and it’s an area we’re confident in.”

[DarkAlman]

There seems to be some sort of plenum between the end of the exhaust and the turbo. Perhaps to even out the exhaust pulses before they go to the turbine.

The split turbo concept seems to have carried over, as we can see the turbo air intake at the front the chassis.

The MGU-K mount so far forward is a choice. Curious how that gets connected the transmission? Many decisions seem to be to make the rear of the car as narrow as possible. That may be Newey's influence.

The double air intakes / throttle bodies is another interesting choice. Maybe they want to be able to control each bank of cylinders independantly?

Now I'm wondering if they will be running 2 separate water/air intercoolers, one on either side of the chassis.

What performance advantage? No one can look at the traces from last season and tell me Honda had better deployment than Merc.
