I think it differs vastly more car to car, didn’t I hear somewhere that the Mercedes team are actually the only ones running a charge cooler on their engine?
They all are.There is a bizzare rule in the regs that stops them running less charge temp than 10 degrees above ambient, so at a hot venue charge temps are going to be stupidly high. That's going to mean smaller charge coolers than they could otherwise use. Very odd one.

Here is the article regarding cooling...

You do look and wonder how they are aiding aerodynamics... (not trying to be armchair aerodynamicist).
They're vortex generators.I'm far from an expert but I'd guess they're placed at the point where the airflow wouldn't attach properly to the bodywork anyway and are designed to both give a clean break between the air flowing over the rear wing and the stuff going out past the rear wheels; and also to accelerate the air sticking to the bodywork somehow so it passes over the rear wing at higher speed.

The colour is Papaya Spark, a metallic/pearlescent colour from the road cars. Lovely.https://www.autoblog.com/2018/02/23/mclaren-mcl33-...
The Renault photo shoot car wasn't the RS18 https://www.motorsport.com/f1/news/renault-admits-...
[I]“To be extremely clear, the car that we showed in digital was really a presentation for the livery,” Abiteboul told Motorsport.com during a Renault event in Paris.
“I have seen on forums people trying to extrapolate things from it. Well, calm down guys – don’t try to calculate the wheelbase because it will not be representative of anything!"[/I]

It sounds like this rule is to prevent the likes of Ferrari giving customers non-current engines, such as Manor & Sauber in years gone by. People keep claiming Merc hamstrung customers but a) it was cheaper for everyone to have the same kit, which is why their engines are cheapest and b) it gave their rivals a harder time if the satellite teams could nick points off them, this was especially true in 2014.
I think the rule also requires customer engines to have the same engine modes as the manufacturers have. There were some instances last year where Mercedes seemed to have an extra qualifying mode up their sleeves during Q3, or at the end of the race (e.g. Bottas in Baku last year chasing down Lance Stroll who had the 'same' engine). An observation on colours, I have worked alongside many Chinese colleagues over the last 8 years and Orange is a very popular colour in China, it is considered to bring great fortune. It could be a Marketing tactic aimed at selling more road cars in China??
Secondly, does anyone know if the halo 😇 device has been tested in heavy rain? It seems perfectly positioned to deliver a curtain of water onto the visor. I’d be interested to hear from anyone involved in the development of the thing.

Mclaren used the log manifold, they just junked the standard issue chargecoolers that Merc, FI and Williams used. Merc have always supplied the same equipment to FI, Williams and Lotus. The only difference was Mclaren in 2014 who didn't want the full moo because of their fuel supplier. FI and Williams chose to have updates later than Merc because it suited them in regards to engine changes, such as not wanting penalties at Spa and Monza for example.

Hardware, yes- software, no. See Grosjean, Spa 2015. It sounds like this rule is to prevent the likes of Ferrari giving customers non-current engines, such as Manor & Sauber in years gone by.

Hence the regs now imply software parity. They do seem pretty vague about it though.

Renault have always said the supply identical spec packages to all their teams. Mercedes haven’t done this. I’ve always thought it strange that a team could be legitimately hamstrung by their engine supplier. Glad to see this new directive come in, it should never have been needed.
Renault only supply the power unit lump to customer teams, they don't supply or design the ancillaries/attachments required, like the radiators and piping, intakes and exhaust. so when its all integrated into the final car its far from identical for all teams. Mercedes are the same. The first year of the current turbo engines they used a "log" style exhaust while Mclaren designed a traditional "tubular" exhaust for their customer unit - obviously the Mercedes designed exhaust specifically for the Mercedes engine worked far better.

Now, they can give Mercs rivals, and possibly Merc a harder time.

It has nothing to do with Ferrari providing customers with year old engines. This was already prohibited by the rules but was done a) at the request of the teams who couldn't afford to re-design their cars to accommodate new engines and b) with the unanimous approval of the other F1 teams to allow them to waive the rule.The changes is squarely aimed at Mercedes who, whilst supplying engines of identical physical spec, did not allow their customers to access the most powerful engine maps (they were password protected and changed each race) other than on very rare occasions where the Mercedes team could benefit.
The rules now says:
FIA said:
...all power units supplied by the same manufacturer to be:
"ii) Run with identical software and must be capable of being operated in precisely the same way.
There is also a line about using the same specification of oil and fuel but this is optional due different teams having different suppliers. "ii) Run with identical software and must be capable of being operated in precisely the same way.
I remember reading in a trade mag in the first season of the hybrids that one engineer had said their supplier had given them the minimum cooling specs etc for the engine and they had built the car exactly to the minimum of those. When the works car appeared it had sidepods sizes and inlet sizes etc that meant it was running way below those specs. Now the engine supplied may well have been identical in every respect but with the data supplied the performance of the two cars wouldn't have been.
Could anyone shine some light on what this is? There are two of them on the Merc W09, one either side of the cockpit. I'm guessing at either some kind of transmitter or sensor, does anyone know for sure?
I'm referring to the pale yellow "peg" with the black cap pretty much centre of the picture.
Edit - the screen shot is from this video, it may provide some context seeing them properly and in relation to the rest of the car.
