New R4 Car - Think Tank

[Rally Power]

AP4 regs, the Australia/New Zealand alternative to R5:

More freedom over Maxi Rally regs (wider range of components) but easier to made and potentially cheaper than R5 (in house made cars over external bodyshell/roll-cage package, supplied by approved builders).

Some videos at the NZ Rally thread.

Mark Pedder did Rally Australia (in WRC field) with a 208 from this regulation.

Yep. Because AP4 regs are based in Argentina's Maxi Rally, MR cars are allowed. Pedder's 208 came from Baratec and uses the 1.6T new engine.

Every country outside of Europe can choose the category they want to see in their local WRC event.

That should be another reason to let private tuners homologate R5 cars. They would became cheaper and easier to get.

Wrong. AP4 was a clean sheet exercise which has produced a formula with more similarities to WRC2 than MR. There is a looseness which allows MR cars.

This concept has been sadly proven non-functional with R-GT.

AP4 hardly could be described as a clean sheet exercise as it's clearly based in MaxiRally and R5 regs.

From AP4 reg:
"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. (...) Alternatively a ‘Maxi Rally’ car (being a car in compliance with the 2013 Specific Regulations for “Maxi Rally” Vehicles – Rallies), may be purchased directly from the
constructor in Argentina or through their approved agent as detailed in PART THREE of these regulations. A ‘Maxi Rally’ car may also be purchased in ‘kit form’ and
assembled in compliance with the stated regulations. Such cars (provided they maintain compliance with these regulations) will be accepted as meeting the eligibility
criteria of Group AP4."

You're right! That's why everybody should pressure FIA to ease up homologation processes. In R5, RGT and even on R1/R2/R3.

R-GT is different I think.
Their could be a market for R2 cars for example. You can see some local production in South Africa / Namibia or India.

Some countries in Asia are doing great with their regulation. For example in China, you have various manufacturers homologating cars in group S. In Argentina, Australia, NZ you have some new regulations, because FIA cars are difficult to get, or cost too much.
If you allow free R2 f.e. (I mean not only the manufacturers approved one), maybe some countries would choose to use this.

You could have new cars on forgotten markets (look the situation in Asia now, and what it was 20 years ago), or even some private team in Europe doing it.
