MotorSport New Zealand (MSNZ) and the Confederation of Australian Motor Sport (CAMS) have collaboratively developed these technical regulations for a new generation of 4WD turbocharged rally car eligible for competition in both National and International events within the Asia Pacific region.
The philosophy of AP4 is to establish a set of technical articles that allow rally teams to build locally, or buy cars of parallel design from overseas, that will be of a similar specification and performance to each other and to that of the FIA R5 / S2000 Category cars, but at significantly lower cost.
