My understanding is that Car/ vehicle manufacturers have fleet (over the range of vehicles they make) emission targets to meet at certain years in the future. (EU fleet CO2 emissions by 2030, for passenger cars to be a reduction of 55% compared to 2021 levels)
Very likely that European manufacturers of passenger cars are not going to be promoting their liquid carbon fuel burning models to meet the targets and avoid fines.
For this year, up to June 2025 Europe new car market sales are now slightly over 50 percent for sales of new battery electric cars (15.6%) combined with hybrid electric (34.8%).
The small shop race/ rally car builders can see that support is going to come from only a few manufacturers who want to continue to support the liquid fuels with their brand in motorsport.
e.g We have seen for a long time support for the TCR small car international track race category runs warm and cold from certain manufacturers.
Brazil, 2025 can get close to 30 new spaceframe cars on the grid for their Stock Car Pro series labelled as Mitsubishi, Chevrolet and Toyota.
If the FIA comes to the table the N5 category might be a (at least ) regionally (non large manufacturer) homologated budget class (rally field supplementer) as manufacturers do not care so much about a small number of liquid fuel burners at the back of a rally field, especially if the big brand manufacturers do not have to put any money into it and can distance themselves from the fuel race/ rally cars. https://www.gotothegrid.com/en/blog/...tive-to-rally2 (2024)
