WRC main class in 2025

But, it seems like the whole Andretti/FOM thing isn't helping his reputation in Motorsport a lot(or his stature as the President of FIA).

I know this is OT but how. If anything it shows him as strong president that is doing the best for the sport, not best for the promoter.

But I hope he will also start to do that in WRC.

Fully agree! It's just FOM shortsighted greed that prevents Andretti. But the F1 situation shows that Ben Sulayem can't magically decide and improve things on his own, be it in F1 or rallying.

As much as 80% of the current Rally1 car will remain unchanged when the World Rally Championship introduces new technical regulations for 2027, according to the FIA.

IMHO the technically easiest solution for a new WRC car, which could be atrractive for the current and new manufacturers, is an EV with CE working as a generator. That concept is known for more than 120 years, it works in many applications and was even used by Audi in Dakar. IMHO with well thought-out rules such cars are much easier and likely cheaper to build than the current ones. You have no gearbox, no super duper racing engine and you don't need large heavy batteries either. On top of that you have an easy way to control torque distribution even without using differentials.

Yes, it's something new and it won't sound like today's car but WRC needs something new. It badly needs something new.

So in princip the same concept as this one

Basically the same concept as the first ever Ferdinand Porsche's car in 1898... and same as every diesel-electric train.

PS I didn't read your link because the google search appears to me in Norwegian.

Yes like the Opel Ampera.
While it's a feasible way to get "electric vehicles" competitive in rallying, a serial Hybrid is technically a very bad solution in general. If the people/politics/media would be able to understand what they are lobbying for they'd be very upset that "their' BEV Dakar Audi is just a very inefficient Hybrid with a "evil" ICE.

The big heavy E-Tron had an average fuel consumption in the far worse terrain about 40 litres/100 km. That is definitely less than the current WRC cars. I fail to see why it is worse.

Hm might be different in competition but for road cars it was less efficient than a comparable parallel hybrid, an Ampera in normal running was said to use between 7 and 9 liters per 100 km for example.

Presumably the fuel consumption of the Audi was with a pre charged battery?

Do you happen to know the approximate fuel consumption of a T1+ Toyota/BRX/...?

Nissan is using similar technology on the new X-trail. There might be a future with this technology, when the engine runs on biofuel.
