So teams basically get to make the parts that store hydrogen and convert it to electricity? |

I don't really understand it either. The fuel cell stack is the thing that extracts electical energy from the hydrogen fuel. I guess it makes sense for this to be the focus of development since all the other stuff is well understood and highly developed already. I don't know how the battery fits in to this unless it is to store energy recovered under braking, which would surely be a good idea.

This has the advantage of the fuel cell never having to stop, but just producing consistently (usually a benefit for power sources) and the extra power in the battery can be used for more wheel power or range. |

So, no continous development. I think it will be a lot like in DPI. I don't remember when was the last time a DPI had a visible change. |

Even if there weren't big visibile changes on bodywork, if memory helps me 2018 mazda dpi (or maybe 2019?) was basically a complete new car under the skin since it passed from the original crap riley tub to a new and updated version made by multimatic.

I can’t remember how much changed. That said it made sense for Mazda to change in 2018/19, as the previous chassis hadn’t lived up to expectations

Multimatic was always responsible for the composites work and used for the aero development, and the tub has not changed. The 2018 revision has a completely new rear suspension to use a conventional layout instead of the Riley rocker, new front under aero which was apparently more to fix cooling problems, and some various weight reductions to try to get down to the limit.

The chassis is homologated, hence no changes allowed, bar what IMSA/ACO allowed under their ''Joker'' rule, which were minor. |

Just a thought - is there anything stopping a LMDH program to be rehomologated as a LMh?
I know a LMh cannot be rehomologated as LMDH as the monocoque is not build by the permitted manufactures, but to my knowledge there should be nothing stopping a LMDH from scrapping the Hybrid system at Le Mans, adding the needed weight and then run under the same rule set as LMh? |

I guess that depends on the new lmp2 regs, right?

Would it work the other way round as well if the LMh monocoque was designed by one of the approved constructors? |

Whether it's theoretically possible depends on whether the next gen LMP2 monocoques follow all of the new standards LMH does. They likely do but I haven't seen that officially anywhere public. Once you get past that it's possible to build a car legal for both but basically every LMP2 or LMDh car is in practice going to be 100mm too long as is (same thing with the ORECA 07 to R13 transition though) and they haven't mentioned if LMDh will have the minimum frontal area requirement.

Audi and Porsche cooperating closely on LMDH: https://m.motorsport-magazin.com/24h...ercar-daytona/
Main points: • Audi's new head of motorsports says that the two companies are coordinating their LMDH projects very closely. He and Fritz Ensinger at Porsche are working to identify areas in which there can be a synergy between the two brands. • Ensinger hopes that more manufactures (e.g. Ferrari and BMW) will join. • Officially, there has been no decisions on a chassis supplier. • Audi would prefer to use their DTM I4 turbo engine (mislabeled as a V6 in the article), but Porsche think an NA V8 would be better, as there are some vibration issues with the I4. Audi has solved those for the sprint races in DTM, but in endurance racing it might be another story. It seems likely that both brands will use the same engine. • Despite cooperating in the development process, both manufactures will race each other hard on track. |

Rather disappointing if they're going to share the engine.
Then the two cars will be only differentiated by the teams running them. And the upper bodywork, but that's not a performance differentiator. |

Disappointing, but again, pretty much expected, to be honest....

So it will be basically a kit car.... same lmdh, different bodywork.

And in GT3, the Lambo is pretty much a re-skinned Audi as well. |

I could agree huracan and R8 share the same engine, even if each of them tune it in a different way as far I know since lamborghini can't use R8 restrictors and reverse, but are however 2 different cars buit on different chassis/platform with different aero and other features. |

Understandable but really disappointing. Would have at least liked Audi and Porsche to use different engines.

The production cars share the same basic platform and drivetrain components don't they? I wouldn't expect any different for the GT3 cars. If fact doesn't quattro manufacture the spaceframe for both? |
