Funny how a lack of wing mirrors really unbalances the look of a car (to my eyes anyway...)

Hi aleks_ader, you seem to have a good grip on the regs. Let me ask you a few questions:
1. I believe there is a clause somewhere saying you may only harvest from 2 sources. Where is it? I can't find it.
2. Do you have to release stored energy to the same 2 systems? Or is it free? In other words: can the 919, which harvests from the exhaust and front axle, then release that energy through the rear axle?

I find these to be the most interesting part of LMP1 hybrids, and I can't find them in the regs

Are they not mandatory? Why else would the Audi have them in a useless place?

[enri_the_red]

yes, but that energy is included in their allocation of 8 Mj/lap; it's not "for free" as it is in F1

No i look for that option but you cannot bend the rules around. All MGU must in WEC 1st go to the ES and vice versa. So tehnicaly is energy flow ERSK<-->CE<-->ES<-->CE<-->HERS no like F1 ERSK<-->CE<-->HERS

there is no need to bend the rules
article 5.2.1
"The use of any device to propel the car, other than the engine described in Article 5.1 above, and MGUs connected (directly or through the ES) to a maximum of two ERSA, is not permitted. "

also take a look at the diagram in the Appendix C, as you can see there is an arrow that goes straight from the engine exhaust ersa to the mgu

they were testing the car a few weeks back at Calabogie Motorsports Park near Ottawa, they had the track to themselves so there was no real need for them. I would think that they just haven't finished them yet or the car looked better without them for photos

I'm posting this part of the track map from the ACO site, because that other one I posted a few pages back is wrong, the corner #'s are right, just the name for turn 4-5, should be the Esses and not Dunlop.

[joseff]

@enri_the_red thanks for mentioning 5.2.1, that answers my question above:
- max 2 ERSA
- No limitation on MGU

I'm not convinced the corner #'s are right... The lead Porsche is taking "T6" at 167.5kph and "T7" at 258.2kph according to the official data... that second speed seems too high to be the 1st Mulsanne chicane IMO (as suggested by that map you posted a few pages back)... I'm more inclined to think T6 and T7 (as far as the WEC timing data defines it) are the first and second parts of the esses... or maybe T6 is the esses and T7 is Tertre Rouge?. The fact that the WEC timing data gives a single figure for "T6+T7" (6.599 seconds for the lead Porsche) suggests the two corners are at least pretty close to eachother (why give a combined time if they're separated by a mile or more of straight road?)...

I don't know why the ACO can't just provide a simple map showing the points, but I've searched and searched and can't find anything that looks right....

Your not kidding i'v spent the last few day since I posted that first one looking for one with both # and names
the problem is some of the individual turns have a name, and some sections or a group of turns have one name.
Doesn't seem to bother them, i will still look around for an old map

It is in appendix C of the regulations. I have to have a loon if they are allowed to use more mgu than ersa. Give me some time.

Edit: Article 5.2 limit to two ERSA. But Appendix C says "any MGU". So seems no limit on where you use the energy, as long as it goes to an axle. No MGU-H allowed.

Ok, so just had a Twitter conversation with the @Autosport account and they advise that T6 is Tertre Rouge and T7 is a short section of straight after Tertre Rouge... Seems to make sense speed wise, and that means it corresponds to the "S6" and "S7" sections on the map in the Le Mans Supplementary regs.... The little marker indicating the start of the section....

Eurosport reported in the coverage that Toyota announced that they'll be switching for a turbo power plant next year.

Edit: http://www.autosport.com/news/report.php/id/119439

They wont confirm it's a turbo but it feels as though it will be likely, which is interesting given the Toyota's power train guy's comments about NA engines last year.
