While the technical regulations regarding the power units are going into their 4th stable year, Mercedes' engine Chief, Andy Cowell, has noted there are still gains to be made. Cowell underlined that the key to these continued improvements are Mercedes' proven testing facility.
Is there any definitive information of which component or area they are talking about?
Yeah. The rest of the article is behind a paywall.
The original machine had a base-plate of prefabulated amulite, surrounded by a
malleable logarithmic casing in such a way that the two spurving bearings were
in direct line with the pentametric fan, the latter consisted simply of six
hydrocoptic marzelvanes, but the ambifacient lunar vaneshaft clearance pocket was 0,02mm short in the long dimension, preventing side fumbling from being effectively prevented.
Is that quote legit? Because I'm an engineer myself (software and electronics) and tbh that sounds like it was directly lifted from an episode of Dr Who.
As a licensed aircraft engineer (dirty hands type of engineer as opposed to desk) I can confirm the above translation is indeed 100% legitimate and accurate.

That's a hell of a lot for it to just be manufacturing error - someone misread the CAD model?
It does seem a lot to me too. But as someone that knows jack --- about tolerances, what would be acceptable? As in: what are the ranges in this context? Feeling a nerd chub coming on
0.2 millimeters is the tolerance of the everyday shaft or bore you would need to fit your run of the mill ball bearing.. and everyday and run of the mill just won't cut it for Formula 1!
8 thou might as well be the grand canyon of crank journals. That's a big screw up at this level. Would they even run .002 clearance normally?

Gah! hydrocoptic marzelvanes?!! Gosh! And here I thought these guys were at the pinnacle of engineering!

You must be joking, most everyday sized bearings say in the 10-100mm range, 0.2mm out on a shaft or a bore would be knackered, the tolerances for out of round/deviation around about a tenth of that, and for nominal size a twentieth.
AMuS reported that the spec 2 engine broke down after 3700 km on test bench on tuesday. So Mercedes decided to wait and solve the problem until France.

0.2 is an interference fit.. So if you off by that. It wont be knackered. If its loose by that.. It might stay in there.. You might live..

3700, huh?
I thought is was 0,2.
Or 0,02.
Might want to re-run your calc's there roon..
since.. even by my rough 'back of the envelope' reckoning.. you may be out by an order of magnitude, or 3..
give or take the odd.. parsec..
"Well, we knocked the bastard off!"

I guess my Dr Who analogy was pretty close to the truth, didn't realise the joke went back so far though... 1940s.
0.02 though doesn't seem too bad for a bad that would have significant tolerance stack with many parts right? Or the tolerances that incredibly tight that even this would never happen? If so that's bad news for this tech making it to road cars in any form over the next decade...

It's just a number a journalist or their source made up. So vague as to be useless. They changed the number from 0,2, to 0,02, then to 3700, and the unit from mm to km. Dice rolls may have been involved.
