Not sure where to put this - FOM considering active aero and 4wd to improve efficiency with next gen PUs.

Well, 4WD at least makes sense, from the recovery angle. Active aero feels like an excuse to do something instead of touching the ICE, of which they're suspiciously silent about.

Ya, LMH style recovery system and may be the engine as well. Im not surprised if later they write the regulations so that the engine would be functioning for the two separate competitions WEC and F1 to attract manufacturers. But thats how the sport moving forward, just take a look at DTM-GT3-SGT, later on all the technical regulations would be standardized to reduce cost

Active aero, more drag reduction on straights seems logical if you want to try to reduce the ICE & Fuelflow with 50%.

But 4wd? Maybe the motors can be lighter if would only be front wheel generators, only used for braking recovery.

Nice Brabham t50 enters the chat then. xD

Maybe the motors can be lighter if would only be front wheel generators, only used for braking recovery.

Why would they be? They're exactly the same whether you only use them for just recovery or drive as well.

Exactly! If they are there for recovery it makes sense to really utilise them!

Hub motors

Hub motors might be a bit too much. There's already a bit of whining because the tires got heavier for this year, and even more about the larger rims...

The have more time to cool if not used between brake zones and allot less wear. So they be made smaller.

With the efficiency of electric motors and the wast quantities of air flowing I don't think that's much of a factor.

Looks like they want clarification on the 2025 engine regs already this summer.

''The goal is this summer. That is not an easy task. We want a new start. The engine has to be cheaper, remain hybrid, run on sustainable fuel and in addition it should not add extra weight to the car. It must allow manufacturers to expand their portfolio for future technologies, in addition to purely electric cars,'' Domenicali told Auto, Motor und Sport.

So it'll probably be settled by the end of 2022...

Going by the 2022 chassis rules they'll be finalized Jan 1st 2025

Today they revealed the new Ferrari 296GTB sportscar, equipped with a V6 hybrid engine. Surprisingly, it has same hot-vee and 120 angle configuration like Forghieris V6 turbo from the 80s.

It's quite possible to become the spec engine of Ferraris Hypercar for the WEC, but could this configuration (two turbochargers, situated inside the V) also be from interest for the 2025 regulations?

McLaren also just produced a 120° V6 with hot vee turbos, for the Artura
