Someone said that 2015 Merc PU has indeed gain some HP – not much over the 50HP limit – but that is not due to their new Bosch 500bar injection system and it`s rather to an increase in fuel consumption …
It`s a fact that in 2014 one of their big advantages was Ferrari and Renault having had many issue regarding both PU and ERS this ending to the fact that they were down on power. Therefore factory Merc cars need to carry less fuel and is speculated that they could start with 12 to 17kg less gasoline race depending. And that is worth somewhere between 4 and 6 tenth per lap …
Now in 2015 they have more HP but despite having a better DI system and even a more efficient ERS in general and MGU-H in particular (that could give them almost anytime those 160HP allowed by the rules) these things above mentioned didn`t cut fuel consumption more they`d have liked …
In addition to that they increased also the DF levels from last year – one reason being in order to have better rear tyre management for 2015 improved rear Pirelli tyres - hence having now a draggier car this added to the fuel consumption issue … and not to mention the rule for having a PU or ERS for 5 races they have to strength both PU and ERS components with a bad effect on fuel consumption from PU perspective, at least …
So now they have to carry more fuel into the start of the race but at least they are faster on the straights (one of their weak point last year) and have better tyre wear and balance.
But they have a price to pay: they lost almost half a second due to the increased fuel consumption and bearing in mind that the total mass of the cars was raised with 10kg from last year this led to more time loss over a lap.
Whatever, what is really interesting is the fact that in spite of of those losses they seem to have some gains after all, but what is more puzzling - in case of myself - is knowing they spent more tokens than anybody else and maybe they were spend more for safety and reliability reasons due to their 2014 issues … but I`m aware of the fact that another reason is the bespoke law of diminishing returns and that`s why Ferrari was catching them so quickly …
Based on what we've seen on track so far this could actually hold some truth. Am I right in saying we haven't actually seen a faster lap time in the races than 2014 yet?
If this is true, then Mercedes need to replace Toto and Paddy, and bring back Brawn. One of my biggest fears was them going into 2015 and completely messing up the car. And the people I'd blame for that is weak management. Paddy Lowe's record of cars is average at best.
Just seen this on another forum:
"Commenter from German TV just said that Rosberg has told him, that in his opinion, they would have been faster with last year's car and apparently they still have some work to do for the season"
It looks like there may be some truth in those comments. The W06 could be slower than the W05 in terms of ultimate lap time.
As you said there is some truth between those lines ...
IMHO W06 this faster than W05 but this year the car is tyre limited and resembles me the 2012 situation with RB 08 in the first part of hte season, coz those 2 hot laps in the end of the first stint Lewis was doing on used soft tyres in China are more than a proof of car is capable of ...
In addition to that me think they are running in conservative mode even for the entire PU system bearing in mind the 4 engine rule if not their PU issues they had last year.
Another issue is their A123 system batteries that is running hotter that last year, now that they could run the ERS more time and more to the maximum 120KW allowed by the rules.
That's why one of the reason why Ferrari is closer to them in the race is the latter advantage having Saft batteries which is supposed to run much cooler hence their ability to run more with ERS engaged.
You could add to the equation the higher fuel consumption & the car mass increase and maybe you could see better the true picture ...
