The Fenix solution is different from the VF1 club. The VF1 cars were over top ultra detailed cars with VTA rims and tires. Beautiful works of art but targeted to a smaller select group of racers with specific skills and philosophies. The Fenix car is for the masses and and doesn't deviate much from a standard F1. It isn't going to fold in half in a crash nor does it require special rules. It uses normal F1 tires and everything else but just requires a shorter battery. You could run it with standard F1's under the same rules if needed.
