Without battery, this means ERS-H feeds it's energy directly to front motor? IMO, that's worth very little, 30-40 HP?
Do we know % ERS-H of the whole ERS in normal operation? 2MJ or more? |

I seem to remember that from the diagram ( and video) that Porsche had explaining the hybrid system, the power from both the breaking and the ERS-H was supplied to the battery. I think that the issue may have not been with the battery itself, but with the brakes. Coincidently (or not) the #2 suffered with a brake balance issue all weekend and so new brakes were fitted. Perhaps that was the root of the problem.

A new chassis for # 2 for Le Mans...and beyond. It seems that they still cant get to the bottom of the cause for the difference in pace between the two cars.

Well according to the article , when the #2 drivers drove the same car in testing, they were on the same pace as the #1 drivers. It's not the drivers. It's the chassis/car.

I assume they generally tear down and rebuild the cars after each event and that they have a spare monocoque, so why not use that spare and build up a totally new #2. Hopefully it resolves the issue. Richard |

Sport Auto claims that Porsche have had battery issues and are thinking of switching back to their 2015 spec battery pack for LM, though it will cost some performance.

If they are indeed having issues with the newer batteries, it may be a smart move to sacrifice some performance for reliability. From what we have seen thus far, reliability seems to be a linchpin in everyone's game. Throw 24 hours in to the equation and you start to have variables which cannot be accounted for in any testing, regardless of the duration. As long as the performance loss isn't substantial, it would almost seem like a forgone conclusion in reverting back to last year's battery come Le Mans.

I think it's good that there's still reliability issues. If they affect all three works teams it'll just make Le Mans itself a lot more interesting. Plus it means they're all pushing the available tech. ![]() |

Do you think the yellow dial in the middle goes up to 21 for Webber?

Last test before Le Mans completed: 8,427km completed. 1.5 times LM distance.

Funny comment, maybe they say that in reference to the Audi's breaking down in spain?
I'd call their speed, the Porsche's greatest strength. |

i too thought maybe audi's silence is due to them not having good results at aragon. teams tend to brag a bit about their testing going well, getting a lot of mileage into the cars and so on. the fact that audi say absolutely nothing about the test, to such a degree that you might even think it didn't happen at all, doesn't look like a particularly good sign.
