Here's a comparison between former and existing cars and what seems to be coming just to put things into perspective. The numbers are what I could find so if somone knows better I'm happy to be corrected.
WRC 2011-2016
1360 kg with driver and co-driver
global race engine (1.6T I4) with 33mm restrictor ~ 310hp
limited aero
WRC 2017-2021
1360 kg with driver and co-driver
same engine but with 36mm restrictor ~ 380hp
lots of aero
Rally1 2022-2024
1430 kg with driver and co-driver (hybrid system is 84kg)
same engine as before but with hybrid boost ~ 380hp + 136hp = 516hp when boosting
less aero than previous gen but still relatively complex
new Rally1 2026
weight unknown
engine unknown but with fixed torque curve and max power 330hp (basically everyone will have the same performance)
common safety cell, aero and center of gravity tightly controlled and capped, top speed capped (sounds like some form of BOP)
design and car shape more open than previous gen
Rally2 based transmission
400k cost cap
Some speculation about 2025:
Since they say that in 2026 the current Rally1s will still be allowed and their weight, aero and power will be reduced I assume that means they will adjust these cars to 330hp like the 2026 spec and equalise the weight or something close to that.
About the Rally2 kits:
Current Rally2
1390kg with driver and co-driver
engine with 32mm restrictor ~ 290 hp
limited aero
Rally2 WRC Kit 2025
engine with bigger restrictor
larger exhuast, optional paddle shift gearbox
rear wing
They say they want to bring them closer to Rally1 performance so assuming the target is 330hp is it possible to get there with just the larger restrictor and exhuast? On the aero side it depends how much they limit the Rally1 aero, not sure just a rear wing will be enough. Also these cars might need to lose weight which I'm not sure is possible. This WRC kit only really sense if they can get them really close to the new Rally1. I've seen people compare it to the 2011 era RRC however there is a key difference: that car was a more expensive car downgraded while here they are uplifting the performance of a cheaper car. It might work if they can achieve the performance level.
So for 2025 manufacturers need to downgrade their cars by removing the hybrid, lowering power and simplifying the aero and they can keep using them for 2026. That's quite some work on the aero side and retesting the engine but you can then use the car for 2 years at least. New manufacturers or tuners could come in 2026 using the new Rally1 rule.
In the end we have to see the full rules written down but I think the key change is the performance cap. That was in fact what attracted a lot of teams to WEC, according to interviews with manufacturer representatives that i've read. They had a sort of guarantee that if they can reach the performance target they will be competitive without getting involved in an expensive development war. Indeed for this season some of the teams have changed nothing on their cars. The biggest changes will be made by teams that are having issues with performance or reliability. Robert Reid was at the Spa WEC race last year and is now at the Qatar race so maybe they're getting inspiration from there.

It is mentioned that rally2 wrc kit includes optional paddle shift.. Does it mean rally1 cars change back to paddle shift from 2025?

In my opinion it is not clear from what was written in the plan and we will have to wait for the final regs in June.
Another thought about Rally2 WRC kit, perhaps the objective is not to achieve parity with the Rally1s but instead offer a cheaper way for drivers to get experience with a similar power to weight and aero before going to Rally1s. This might be them recognizing and trying to fix the issue with lack of options to get experience at top level for new drivers.

The power figures have always been officially far lower than in reality. It's been decades since since someone officially published anything close to reality
Even the very first R5 car (Fiesta) had roughly 300 Hp and that is ten years ago.
IMHO It will be difficult to level the Rally1 and Rally2+ cars but I expect the Rally2+ to be used mainly by gentleman drivers and not by many serious competitors.
Anyway about the new rules. Finally private tuners can build a WRC car. That is a breakthrough equal to a revolution in the sport. I am very happy about it.Last edited by Mirek; 1st March 2024 at 11:08.

Yaris rally2 - should be 211kwLast edited by TypeR; 1st March 2024 at 11:20.
It was on qualifying stage, he rolled the car and it was said that he won't be able to start the rally. But team managed to repair the car and he did start and dominated drivers like Rossel, Gryazin...
