interesting! but what "homologation" means in that sense? is it "authorizing" the use of a car or they need to actvely be involved in the construction, selling, injet money...?
for example: can the vw group just say "yes, anyone can get a modern cupra small crossover model and turn it up to R5 specs...?" or the vw group kinda need to be involved? idk how that works hehe. i dont imagine ford giving fiestas do msport with rollcage installed for example, i understand that msport (and others) have authorization from the brand and fia to remove everything from a fiesta and turn it into the rally model.
am i too distant from reality? cuz if its like that it seems easier to kinda "hey manufacturers, next R5 rules is for small crossovers, can you all allow models "?
