Renault is using a 4 cyl 1333 ccm engine (R2C) on their Rally5, will they use the same base for their rally4 and rally3 cars?
Or will they go R2B for their Rally3/Rally4?

No need to change engines as Rally 5/4 (and partially 3) allows the car upgrading, just like in Gr.N/A days; Renault (and hopefully other manus in the future) will sold a Rally4 kit for Rally5 owners. Besides, Rally5/4 turbo engines max capacity is 1333cc (non turbo limited to 1600cc in Rally5 and 2000cc in Rally4).
Btw, Rally4 rules changes approved in last June (including a new 30mm restrictor) will only be effective from January 1. The cars will become a bit slower but, surprisingly, Rally3 cars will also be forced to use the small restrictor, meaning they won’t get any advantage on tarmac events regarding Rally4 cars.
June WMSC resolutions on Rally 5/4/3 can be seen on Regional Rally Championships section: https://www.fia.com/news/fia-announc...l-decisions-18Rally addict since 1982

If tests show that Rally3 need this larger restrictor to be able to get the power needed to utilise the 4wd, FIA could opt to keep a bigger restrictor for the 4wd I guess.
