I would guess they all made a few different versions, how else would you decide what way was best?. end of the day, all of them knew the regs at the same time.
I have'nt read Ferrari, Renault and Honda(2015) putting in that much effort into the new regs at the time.......which is why MercedesAMGF1 PU's were so reliable compared to the competition starting in 2014.
Honda had spent 500 million before and still failed to produce a decent engine, Renualt also had a very expensive research and development program for hybrids and Ferrari was busy desiging its LaFerrari car. Your just looking for any excuse to dismiss Mercs achievements. They all agreed on the same day, that same day was when they decided on what version of two different types of engine they was going to use. Merc did the better job.
No, at the time when these turbo-hybrid formulas were introduced Italy and France didn't have ANYTHING having to do with hybrids(except the Laferrari which used the HyKers and that car cost over a million USD.). Honda had played with hybrids before but not at this level. When Honda entered in F1 in 2015, they went thru 65+ PU's with Mclaren during that time with Mclaren and were getting nowhere. Germany was heavy into hybrids in motorsport like Porsche and Audi in WEC....on or before the turbo-hybrid formula was introduced(not 2014 but before 2014). Needless to say, Ferrari, Renault and Honda were already at a disadvantage when they agreed to the turbo hybrid formula all the while not knowing the huge advantage Mercedes would have.
+1 Turbo hybrid was centre to Mercedes road product future, hence their 2007 production start. Todt was very understanding to Mercedes lobbying, and got his quiet revenge on LdM.

Pointless argument, in my view. You will always find a team or an engine builder which has an advantage from the outset when there is a formula change. You can never dismiss already aCquired knowledge in one fiel or the other. It's naive to pretend that some are caught unaware, and others benefit from an unfair advantage.
I know precisely how big business operates, where decisions are regularly triggered by individual personal motivations that are then backed up with data that fits their primary motivation. We see it often.
So...if you're Ferrari/Renault/Honda, why not push back? What was F1 going to do? And didn't Luca quit in 2014?
Exactly my point ! I never heard much complaint coming from the other engine builders over the years. The FIA/Mercedes/Todt engine plot only lives in the mind of conspiracy theorists, IMO.
Luca de Montezemolo should know this quote from Mark Twain: "It's better to keep your mouth shut and appear stupid than open it, and remove all doubt"
That link doesnt say any thing that isnt already known, the same article also says all three started work at the same time, which is true, how can one start before the regs have even been decided? "Jean Todt said at the time, “Mercedes, Renault and Ferrari knew for five years what engines they would need to use this year. Mercedes has simply done a better job. Such is motor sport.”" If Merc started as soon as the regs was agreed, and the other two pissed about. Thats down to them two, Not merc gaining an unfair advantage. Which was an opinion shared on the grid " Christian Horner claims that engine supplier Renault is behind schedule in its development of the V6 turbo hybrid engine because it simply "started too late" working on it." "Talking to Sky Sports F1, Horner said: "It's quite simple really: we've had a massive engine regulation change and Renault has turned up and it wasn't as ready as some of their competitors were. So we've been playing catch-up. Renault is working tremendously hard at it and we're slowly closing that gap down”."
We understand, everybody tunes in to watch Lewis. Other drivers are boring. Don't worry. You can see him race tomorrow.
