The Main WRC Class has been silly for quite a few years; now as well even the points system for the main wrc class. Leave the Rally1 for the big budgets and big attitudes etc.

I suggest an AP4 type system to run with the WRC Rally 2 class, Rally 2A to run the current Rally 2 and R5 cars and Rally 2B to allow AP4 type cars to be part of the 'Rally 2' class. Modify the AP4 rules to allow the 2B car to be slower than Rally2A. The 2B build budget to be far less than a WRC main class car. In NZ the AP4s have run Audi S1, Holden Barina, Mitsubishi Mirage, Mazda 2 (more regular cars Paddon's AP4 Hyundai i20, Skoda Fabia AP4, 2 & 4 door Ford Fiesta AP4, Toyota Yaris), made for Australia 2 door Mini. Rally 2B mainly aimed to be a semi-professional privateers tuners class so they can turn up with one off builds, BMWs, Tesla(with a 'class standard engine', Nissans etc converted to rally cars, play with their own engines, transmissions without having to air freight engines back to one European factory for checking etc.
