it's a huge power/mass rate, only f1 and indycar at 1.5bar turbo pressure have a better rate in the whole 4 wheels motorsport (if we don't include dragster racing).



You still don't understand that achive >800hp from a racing engine is quite an easy task... you basically just need to increase boost, rev higher and burn more fuel (or get a turbodiesel V12 peugeot).

The tricky part of the scheme is to make this reliable and economically sustainable.
Repeat... just think about f1 ICE's... designed and developed by the finest engineers and are however less powerful and have a shorter lifespan... each unit costs about 10mln or even more. Just think how expensive could be a 850hp - >6000km endurance bound unit....
if toyota currently spends about 80mlns for WEC, that budget would be barely enough for 4 ICE's





*(830kg + 80kg driver weight)
I'm not sure what Toyota is spending now but I doubt it's anywhere near the 75-80 million dollars when Porsche and Audi were around. They have been using the TS050 for 3 seasons now with the current evolution going back to 2017, at least the hd package.

It should be noted, though, that they're developing an evo package for the TS050 as far as aero and maybe some electronic and mechanical upgrades. And the aero is significantly different to what we've become used to based on what few photos exist. So they're still spending some money at least on R&D for the TS050, and I'm very eager to see it in the flesh in a couple of months time at the WEC Prologue.

But now onto the main reason I came here to post relevant to the topic, is that the ACO are maybe looking at adopting a modified version of the original proposed LMP1-influenced hypercar regs. Other things being looked at is a cost capped hybrid system featuring part time AWD operating similar to what the Audi R18's pre-2014 system did, with the system being inactive as far as AWD below a certain speed.

I found this on SC365, so take it as you will. Also, that same article says that we won't hear anything from the ACO on the subject publicly until Le Mans race week.

Hypercar update:

It’s understood a FIA Technical Working Group meeting on May 16 led to no definitive decision, with further meetings having since taken place.

Sportscar365 has learned of a latest proposal that would be based on the prototype-based Hypercar regulations announced in December, but with reduced power levels and increased aero.

It would also feature a front-wheel driven ‘mild hybrid’ system that could only be activated at speeds above 120 km/h.

The regulations announced late last year called for a 200 kW electric motor as part of a €3 million cost-capped ERS system.

The FIA’s previously announced production-based hypercar plan, per the requests of Aston Martin, Ferrari and McLaren, meanwhile, appears to no longer be on the table, with discussions on GTE Plus and DPi also having cooled in the recent week.

Increased aero. Because wind tunnel testing is known for keeping budgets down!

This is boring now. Just announce the top class is using NGTC BTCC regulations and be done with it so we can have *something* decided.

Anything's better than the horrible bop thing mess announced at Sebring, even that one - regardless of the absurd vagueness of it again - so it's not all bad.

Good news in my view, that means at least Toyota will continue with Glickenhaus (hopefully) and the privateers can fight against Toyota with their current cars.
