The actual ICE (internal combustion engine) produced by Mercedes, FERRARI and Renault this year are remarkably close in performance (ICE power output), Mercedes big advantage comes from the hybrid areas, to this must be added the capability to sustain maximum performance (from both ICE and electric) for the duration of a race distance with reliability, and thereafter for the number of races the PU is expected to do during the season, Renault reliability problems which were known to them from before their PU run on track (they advised their customers not to excide 250km and more than 75% output) during the winter testing, thereafter it took them 18 weeks to declare that they could run at 100% , all this took its toll on them for the rest of the season, and most probably on the next one too, it is starting to look like unless they will earn some sort of equalisation derogation they have little chance of catching-up with only 48% of engine components allowed for a redesign.

My expressed opinion on here is fully accompanied by explanations (of course, my opinion/s).
And that's what I expect of others to do when commenting either in the positive or negative, and that includes labelling something as crap.

107SS2009: The actual ICE (internal combustion engine) produced by Mercedes, FERRARI and Renault this year are remarkably close in performance (ICE power output), Mercedes big advantage comes from the hybrid areas

This seems counter intuitive given that the output of the electric motor is capped by the regulations, whereas the ICE output is not. Your comments regarding consistency in harvesting energy and testing make sense, but I'm struggling with the quoted bit.

I read earlier that the different systems of each manufacturer were remarkably similar in isolation but that the integration of the various systems is where Mercedes has the major advantage. Am interested in your thoughts/knowledge on this point.

1JETZ/ Beningly, Yes the three forced induction ICE'S produced this year are (as has been expected by those that fully understands this business) closer in performance (ICE power output) than last year's NA V8'S. Explanation, but first a note, (reliability problems which will prevent an ICE from producing its full output for the duration of a race, although it will make all the difference in a race should not confuse this subject). The NA ICE V8'S were air restricted, this restriction was capped by the mandated max RPM limit. The forced induction ICE'S are fuel flow (KG/H) restricted at a max RPM. This is technically exactly why they were (as expected) to be closer in their power output. This is because scientifically there is a limit as to what can be extracted from a given amount of fuel permitted to be burned. Another note, the NA V8'S had a slightly lower fuel flow (KG/H) requirements then the present permitted forced induction ICE'S have. To be continued.

Continued, yes the electric power is capped, but regardless that is where the advantage is derived from. Explanation, the max storage and output of the ES (batteries) is 4MJ/lap, the harvesting from K is max 2MJ/LAP, while its output is a max of 4MJ/lap, the K alone can never fully charge the ES, the harvesting from H is unlimited, while its output is also unlimited, the H can spin (spool-up) the turbo, charge the ES as well as power the K, although the K max MJ'S output per lap still applies to the output of H-to-K it being unlimited is where the advantage of max electric power per lap can be had from. To be continued.

Continued, “Different systems remarkably similar” and “the integration of the various systems” The differences are such that can make for a winning package plus impacting in no small way on reliability and the effect on the car as a package. Although it will be a pleasure to explain these things, it is not possible to do so on here as such with permission of CRASH I recommend a visit to matt somersf1 powerunit architecture, scroll down right side of page and click on subject/s.
And finally both 1jez and beningly appreciates your disagreeing true a dialogue instead of hiding behind the disagree button, men with balls I call you/in my book.
