It's the gearbox for the electric engine for the front axel.

According to Jani, # 2 was about 400bhp down.

Porsche and Audi will be testing simultaneously at Aragon.

Really speaks volume on the nonhybrid power deficit, when the Swiss couldn't keep up.

They did change the differential on the front drivetrain then. Makes sense. I was somewhat confused about this "gearbox" change as I thought and understood that they were referring to the engine gearbox at the rear. Don't know why they call this a (front) "gearbox" and not a differential though.

Doesn't explain why Lieb was 0.7secs slower that Jani in the same car ! Lieb is in the car because he is allegedly the best car developer on the grid, which is why Porsche put up with his lack of pace. If he is slow and can't set up a car then why is he there ?

It is a myth that he is not on the pace. If you study his stint times in the races you will find that he is very much on the pace.
As for the set-up issues: they were having brake balance issues. They changed the brakes and and things improved. They can't figure out why they are not as fast as the #1 even when using the same set-up. They are trying to go a different route. I'm sure that over time they will figure it out.

Spiderman I can only go on the information I have! On outright lap time Lieb is consistently slower than Jani (see alkamel timing) going back over many races. If you have the stint times per driver I am happy to be proved wrong.

Porsche obviously has reliability issues, my assertion is that they could improve on the driver front too ... IMHO

carbon_titanium · 8 May 2016, 13:19 (Ref:3640106)

webber and lieb switched their role... in 2014 lieb in #14 was one of the fastest in the best porsche; while webber in #20 was the slowest porsche driver in almost all races. In 2015 webber gained some speed and #17 became the best porsche, lieb struggled compared to jani and dumas with #18 always slower than #17 (and #19 too). This year seems to watch the same script, even if #1 drivers scored 1,5 points so far, while #2 lead with 43 points.
If things will remain like this, I'd expect to see bamber promoted as lmp1 driver and lieb back in gtpro with manthey new 991.

Anyway, won't be surprised to see Derani in a work lmp1 in a couple or years

It really is not surprising that Lieb is slower than Jani. Jani is the top two fastest driver in the team.

That's my point, Jani is quick, the #2 needs 3 quick drivers or it will drop below Audi and Toyota. Bamber, Tandu and Mako waiting in the wings

Spyderman · 8 May 2016, 18:23 (Ref:3640166)

It's not going to happen this year. Next year(s) will most likely be different.

With the 10MJ reduction, Porsche's ICE might be getting around 500HP now while Rebellion have ~600.

Porsche outpaces Rebellion, even with 100HP less, because they have better aero and likely quite better tires.

GasperG · 9 May 2016, 06:45 (Ref:3640258)

It was surprising that Porsche managed those lap times without the hybrid power, they didn't even have any brake cooling issues.

They were loosing around 5-6s per lap compared to their normal functional car.

Spyderman · 9 May 2016, 06:50 (Ref:3640259)

From what I understand, they had intermittent hybrid power.
They did indeed have brake issues so they had to drive defensively in order to avoid cooling issues.

And the Porsche have the exhaust electric generation.

GasperG · 9 May 2016, 09:44 (Ref:3640285)

As spyderman noted, they were not completely out of hybrid power.

Their PR:
https://newsroom.porsche.com/en/moto...ace-12510.html
"Car number 2 cannot use the full electric power for the remaining race distance"

This reads, that they had some power, but we can not know how much and what part exactly was problematic (MGU-H, MGU-K, battery storage, inverter ...)

Akrapovic · 9 May 2016, 10:28 (Ref:3640289)

They had some power, but you could see from the bar graph on the on screen display that they couldn't deploy it all. Crossing the line with almost half the power remaining at one point.

Of course with a faulty system, there's no telling if the graph was right or not!

cokata · 9 May 2016, 14:51 (Ref:3640363)

The pace of the #2 just proves that there is nothing wrong with the rules. A 20kg heavier car with much less fuel flow was comfortably quicker then the privateer cars. The truth is that P1-L teams are not good enough for this level, it's not a rule problem.

So essentially, when Rebellion was beating the likes of JRM, Strakka, Oak, Pescarolo, Dyson and Pickett, they also would not have been good enough lol. By this logic no-one in the world would be good enough for this level, except maybe Penske or something

Anyway, if you truly believe it's the competitors fault, not rules, then blame Oreca for building such "failure" of a car for the Swiss,.

No i mean that a lot of people are angry that privateers are so far away from the ultimate pace and think it's the ACO's fault, when in reality an "off the shelf" car should never have a chance to compete for the overall win.

Alright, actually agree with you there.

TF110 · 9 May 2016, 20:28 (Ref:3640465)

DSC says it's believed the car ran without the battery system, but still had usage of the ERS-H system. Wonder how much that's worth?
