What fuel types can we use? Whatever they are, the requirement for a catalytic converter means that they will all be unleaded.
Also, I get that the maximum trim ET is now 130 - 60 was just not enough. Shouldn’t the engine ET also be 130 or so?
Finally, what about loudness and safety limits? This is a competition for road cars, after all.
Hi, thanks for your interest and questions.
We never limit fuel type in our rules. Since we are scoring markets, we let people decided which fuel types are smarter to go for. Here, Regular 91 RON is best, but Premium 95 RON doesn’t drop markets down too much, so might be worth it, with Super or Ultimate making all markets 0.
The ET for the van round was 60, to stop unrealistic vans with DOHC and fully monocoque chassis in the 60’s. The ET is from the full car, on the final page, which takes into consideration both the engine and trim ET.
There is a safety minimum in Frunia’s markets already, and as for loudness, if it is better for markets, people tend to go with mufflers, but since track markets can be targetted, it’s not enforced.
