Audi LMP1 Discussion

It looks like there are some openings/windows on the side of this "pod" which could hide sensors pointing towards the front wheels. Sensors of some sort to monitor brake temperature (provided it makes any sense to locate such sensors so far away from the measurement location) ?

It does look a bit big, here are some pics of hight sensor from f1

Many thanks. That looks spot on. Laser ride height sensor assembly then, definitely. One "mystery" solved thanks to you

[sssssssss]

looking at some of the race footage again and also thinking about the on-board video that i posted on this thread before the race, where we were noting how abnormally early the audi was braking, well, it looks in the race too as if the audi always got caught up on the braking periods. they seem to slightly get away from the toyota even on most of the accelerating zones, although they theoretically have 2 MJ less, as well as on the straights, as expected, but they always get caught up really badly and quickly on breaking zones.

[chernaudi]

Low downforce and crappy grip will do that.

[sssssssss]

yes, it makes sense, but it was really exaggerated, which tells 1 good thing and 1 bad thing. the good thing is there obviously is a lot more theoretical performance in the car, and if audi suffered grip issues that weren't temperature-related (like those suffered by everyone), it means the car can be extremely fast, relative to the competition, when functioning at optimal level. the bad thing, of course, is quite obvious: on the dress rehearsal for lm, audi are very far from extracting full potential out of their package.

[chernaudi]

Sport Auto report that Audi are currently testing new software upgrades and some changes to their MGU to try and perfect it's reliability and effectiveness.

[Creep89]

Well the whole article doesn't sound too optimistic for all of the three manufacturers. Everyone has some (serious) problems, at least Porsche could just change back to the old 2015 battery cell pack. The final test of the new Audi components will probably be at the Le Mans test day, without a proper endurance test.

[chernaudi]

Audi have at least one 30 hour test at Aragon next week, and they'll be there most of the week, too.

Racing tires have a limited shelf lifespan, and those that go unused after a race weekend are generally cut up and recycled (if not just destroyed). With a limited amount of tires, teams are more likely to go with less variation of compounds just to get consistent setup data and car behaviour if the conditions stay consistent. If you have 6 sets for quali+a 6hr race, and the conditions stay the same during these sessions, it's rather idiotic to go with 6 different compounds, don't you think?

3 - track temps.

Do you follow MotoGP? Did you watch the Argentinian GP? Some Ducatis were having troubles with the tires and Michelin flew, overnight, new tires with a different contruction, for the day after.

I'm sure the teams could require/demand their tire choices very shortly(one day before FP1) before an European round of WEC(if they can do it from France to South America). It's not a problem of logistics.

Btw, teams don't need 6 different compounds but it would be very appropriate if Michelin could pre-select 3 options that it thinks will work better, for a specific circuit and varied conditions, and let the teams make their choices as late as possible.

Anyway, I'm just a dated guy. Motorsports is heading towards another direction and soon there will be spec tires on LMP1 too

MotoGP bikes have only two tiny wheels and they don't need a million pitstops, AND they are presumably identical unlike WEC.

[Artur]

so what? There are pitstops on car racing but WEC requires very few sets, considering how long the race is. I'm not asking this for everybody but for at least the LMP1-Hs.

I'm sure things won't be like this for the big race because things like this could make a farce of LM. Teams are now limited to use no more than 12 sets at LM(such limit doesn't matter, anyway, as they never used even close to that due to the typical triple or quadruple stinting) but I'm sure Michelin will provide far more sets as options for different circunstances

[Adam43]

To be fair to JoestForEver the length of race is very important to how many tyres you need. It is also reasonable to have assumed it should apply to all classes. If you are concerned about one then why not the others..

[Artur]

They are all different classes, with different tyre rules, so I don't see much trouble in giving this "privilege" to the manufacturers, afterall, that's where the overall win is defined. But that just my two cents...

Btw, Audi starts testing tomorrow, at Aragon, aren't they?

[Starfish Primer]

Did Audi test last week with Porsche in Motorland? Some people saw Audi Sport trucks in Spanish highways on May 15th.

[Deleted]

12 sets at LM (race) is fine atm, but cost-cutting it any lower than that could be dangerous as they'd potentially be forced to take huge risks. And everyone complaints about tire saving in F1, and for reason, we don't want any of that crap here surely.

Also surely in their 30 hour tests the manufacturers are attempting to stimulate the same with tire sets.

Audi tested with Porsche at Aragon and will remain there until Sunday.

Thanks, I haven´t seen any information about them. Porsche drivers posted some tweets and instagrams but nothing from Audi. Dr Ullrich was in Red Bull Ring too.

[sssssssss]

btw, Spyderman, do you have any info on the subject? i know audi were scheduled to test alongside porsche at aragon the past week but i really haven't found any mention of it happening either. we've seen some porsche tweets, but absolutely nothing on the audi side.

[Creep89]

To be honest I have never seen Audi tweeting as much about their tests as Porsche does.

[Starfish Primer]

They are busy calling clowns the DTM BMW team: https://twitter.com/Audi__Sport/stat...64552180420609

This is all the information I have: "The competitors in the LMP1 class for hybrid vehicles have prior to arrival to Le Mans pre-test further test work to do. Audi, the Aragon track shared within the week with Porsche remains until Sunday at the Spanish plant. Toyota is on May 24 and 25 again for further testing after Spa-Francorchamps. There, however, no Le Mans Simulation is on the agenda" - Motorsport Total.

[sssssssss]

weird that we still haven't got even the slightest mention of their test at this point.

[chernaudi]

Anyone know what brand of turbocharger Audi is using? They've usually run Garrett/Honeywell on their LMP1 cars, but Mahle also makes a line of turbos.

I'm asking because the new Audi turbo has stuff that's hydraulically operated that used to be fully electronic.
