Coke bottle separation? Where did word of this come from?

Just a wild assumption on my part.
They have a very agressive angle/radius behind the widest Point of the sidepods plus a relatively low overhanging cooling exit. This overhanging part will increase steepness of the anyway steep adverse pressure gradient in the coke bottle area.
Seeing the red cars often dancing around with their rear end lead me to believe there might be an issue with stability of rear DF. Random separation of coke bottle flow could potentially cause such.

That is one possibility!

Ferrari updated their sidepods in Barcelona, the radius was retained.

It's not that much different compared to others, it's only a bit shorter.

Or power delivery of their V6 engine. Or mechanical (lack of) abilities.

Ferrari has changed the front suspension for Monaco so the front tyres don't rub.

Piola says Ferrari have modified the central cooling vent to a larger version, although I can't tell.

It look like Spain

Look at the difference in size of the central cooling outlet.

So, cliff notes would be..... cool design, but too heavy.

And making matters worse, the weight is added above the cars center of mass.

The PU's center of gravity is dictated by the regulations. The Ferrari PU might be heavier overall, but I doubt its CoG is higher than the Mercedes or Renault simply because they're not allowed to be all that low anyway.

5.4.2 The centre of gravity of the power unit may not lie less than 200mm above the reference plane.

[wesley123]

I don't think cooling systems are part of the Power Unit? And the intercooler seems to be situated over this 200mm.

I think it's a bit difficult to visualize when everything is mounted to the chassis, because the Ferrari PU looks considerably more cluttered with its tubular manifold and whatnot. But, while the intercooler is mounted above the ICE, it's within the "V" and not all that high in the grand scheme of things. And you also have to consider that the Mercedes ICE is heavily reinforced, especially at the top, to maintain absolute rigidity in order for the 125,000RPM shaft that connects the turbine to the compressor to spin freely. Its turbine is also mounted quite higher than the Ferrari turbine.

Basically, the Ferrari intercooler occupies the same space as Mercedes' compressor/MGU-H/turbine assembly.

I think both could have done better if the regulations allowed it, but that's racing, so everything is relative, yanno?

EDIT: I think you're right about the cooling systems and the PU, though. The intercooler is included in the PU as far as what manufacturers are required to package for customer teams, but they're defined within different sections of the technical regulations.

[wesley123]

I have to agree with that it is similar to other teams that have stuff mounted within the V. It raises the CoG for all of them.

But with more thought into it, I don't think the increase in CoG is that much of an issue. It is some neat packaging that clears up some space, both in cooling as general packaging. Plus, it improves on plumbing, and in effect also plumbing weight.

CoG increase can (afaik) very well be overcome by the mechanical setup, and a FRIC system can possibly also help in the increase in body roll. The CoG can easily be "fixed" while there is no immediate fix for the aerodynamic performance or plumbing weight and plumbing in general.

[bhall]

I agree in that I don't think CoG is a big issue here. The caveat, however, is I only know enough about the concept in general to know that a lower CoG is gooder.

I think the Ferrari turbine/MGU-H/compressor assembly is mounted vertically behind the ICE with the turbine at the bottom.

Their water radiator doesn't have to be smaller than an intercooler of an air to air either.
We've seen that the sidepods aren't necessarily smaller than the force india's or the redbull's.

It clearly is a heavier system with a COG that is high, even though it is offset with a lower turbo and MGUH motors.
As for the power of the engine, the intake manifold seems to be a bit compromised, the engine also has a wider angle?
So you may find sidepod space is even more of a premium, especially since the hot exhaust pipes are pushed wider if the engine's angle is wider.

Anyhow, this confirms the first water intercooler package. I still have my doubts about the mercedes powered cars. They seem to be air to air, judging by the charge pipes.

Lotus is confirmed and Mercedes is pretty obvious.

Is that legal?
5.1.6 Pressure charging may only be effected by the use of a sole single stage compressor linked to
a sole single stage exhaust turbine by a shaft assembly parallel to the engine crankshaft and
within 25mm of the car centre line.

[bhall]

Nope, you were right.

Man, I seriously can't read lately.

How so?
You will need to explain how is that obvious.
