[WEC] Porsche Prototype Discussion

[Spyderman]

Having though about it for longer, I suspect you are right Richard.

1. 2015 High DF package (Silverstone)
2. New Low DF package (LM and hopefully Spa)
3. New DF package for second half of the season.

I hope they use the low DF package at Spa for two reasons:

1. It will mean good weather
2. Audi and Toyota will destroy them if they are unable to match their straight line speed.

[GasperG]

I have a feeling that Porsche and Toyota are looking closely what Audi has done and we haven't seen anything near LeMans package from those two.

Well, I hope so.

[Spyderman]

Well they had better have started. It takes a lot of time to develop a proper aero package. Not really enough time now to make major changes.

Not according to the Audi drivers.

Porsche have far bigger torque with it's 8MJ and Audi can't even harvest their equivalent 6MJ on such layout.

Also, the straights are not long enough to benefit R18's superior ICE power.

Interesting quote. As the MJ limit of the cars increases, their ability to harvest energy on one lap decreases. From the beginning of the new rules porsche have been in a higher MJ class compared to AUDI - and silverstone accentuates the difference more than any other circuit in the calendar - so historically silverstone has always been Porsche's toughest circuit. Sure AUDI cannot harvest all the energy for 6MJ - do you think porsche can harvest all the energy for 8MJ? Porsche could barely do it at 4 MJ.

The time to be gained is at the corner exit where you can use the electrical energy (if you have enough), I disagree with the claim ICE power is more important - I think those days are gone - as evidenced by Toyota's performance last year. AUDI do not rely so heavily on MGU-H power as porsche does - so pays less penalty at circuits like silverstone. At le mans, on a much longer circuit, harvesting the maximum emount of energy and using it every lap is no problem. I expect Porsche to again show AUDI its tail pipes at Le Mans this year - everywhere else it is going to be very close. Not to say AUDI were not impressive at silverstone - their qualifying pace surprised a lot of people. We will see how the next race pans out....

Given the current aero pack limit, I'm predicting that some manufacturers, sooner or later, will homologate next year's pack in advance to get an advantage. Just as what Porsche used to do, running new spec 911s in the last round to make them "one-year-old” model for the AM.

Is the rule number of changes in a season, or number of configurations?

[chernaudi]

It's thought (my understanding) that the teams are allowed three main packages max this year. It's not known what they can or can't modify and still stick to the three packages rule, but I've heard that things like dive planes and the underbody tuning vanes might not be counted as "serious" changes.

[Adam43]

In which case there is no benefit in sneaking one in at the end of the year for the following year?

to me porsche at silverstone didn't use the 2015 HD package; that one was much more extreme than the car seen at silverstone last week. I guess that porsche used some kind of "loaded" 2015 silvestone-spa bodywork... some kind of "medium" downforce.
The low drag car will be used at le mans, unlikely at spa; while from nurburgring, like last year, will be introduced the real 2016 HD package.

More interesting would be porsche moves for next year... there will be another updated for the actual 919 platform or a whole new car?

[gustavobamba]

With new rules coming in 2018, i don´t see them building a new car in 2017 and another in 2018... but who knows?!?!?!

Porsche themselves said that they used a slightly modified version of their 2015 High DF package. I also recall reading somewhere that it would most likely be used only for Silverstone.
The 2017 car will be another evolution of the current car. Quite frankly, I don't see that they have much more room to "evolve" , so I expect that 2017 will be a "position holder" whilst concentrating on the 2018 car development.

No new car for 2017. Evolution of current car.

[Spyderman]

A little OT, but I have confirmation that the 2017 911 will indeed be mid-engined , but it is still not clear whether it will have a Turbo.

Like i think they will do... the 2018 car will give them allot to work in 2017

[wolfhound]

Timo Bernhard has a column in Motorsport.com and has written his thoughts on Silverstone.

Very long term rumor for Porsche: they might have an all electric LMP1 car in their future, probably after 2020, according to Sport Auto.

Wouldn't surprise me at all. Makes me sad, but doesn't surprise me.

I would love to see a full electric lmp1 Porsche race car racing in the future.

But thats only my opinion

[cokata]

It would take some extraordinary technology to have a competitive pure EV P1 car. The only way that i can see a competitive electric only P1 happening as early as 2020 is if they gimp hybrids significantly.

[Victor_RO]

The first step I could see towards full-electric hybrids (while battery charging times remain an issue) is if the ACO allow teams to disconnect the ICE from the driving wheels and just use it as a range extender/electricity generator. Initially.

[Deleted]

I would suspect them to request technology-trialing G56 slot year or two before doing that hypothetical electric LMP1. But then again the likes of BMW aren't gonna sit around silent if ACO-FIA is gonna allow such tech for the 24 hours, because of course people want to "win it first" to get the headlines.

That is still a hybrid. It's called series hybrid and it will be less efficient then what we have now due to the multiple energy conversions going on.

An proper EV will only work with quick-swapping batteries, or if they go down the Formula E route which is silly IMO.

[TF110]

Changing and recharging batteries in the pits instead of refueling. That doesn't sound silly, but yeah, car swapping does.

[CTD]

Remember a pure Electric LMP could also be refuelled with Hydrogen.
