Very good point!

Maybe R4 is a mix of S2000, Gr N, WRC ?

Only s2000 and N4 looks more real.

After GpB was cancelled after 1986. It was amazing how quickly manufacturers adjusted to GpA rules.

I'm amazed with all this fuss around a possible R4 class and its purpose to replace WRC1.6T...

Let's be clear: in order to homologate a R4 car a manufactureur must produce 2.500 street cars, and has we've seen in N4, no other manu besides Mitusbishi and Subaru wants to exercice that kind of obligation.

After Ralliart closedown most probably only Subaru would cope with it!
(That wont be an isolated case as R1 also has a unique model range: the Renault Twingo!).

So, R4 just make sence to boost N4 cars, giving them more competitive parts (like sequencial gearboxes) not allowed under Gr. N rules.

In no way R4 can be seen as a WRC1.6T alternative.

And there's no need to wait till september to know that S2000 new homologations will be banned from 2011: that's already decidided.

It was also told that WRC1.6T cars will be allowed in every FIA championships (WRC, IRC, and Regional Series) and in national champs where allowed by local NSAs.

Only issue to be clarified is the possibility of pre-2011 homologated S2000 cars to receive a re-homologation with a 1.6T engine, in order to be competitive after 2010, even if not allowed at WRC rallys (an unexpected rule maybe linked with a hipotetic boycott from IRC towards WRC1.6T cars?).

IMO also R4 is just upgrades to N4 to get them more competitive against S2000 cars, not replacing 1.6T WRC cars.

By this press release I understand that Mitsubishi will take over some of the activities of Ralliart and Mitsubishi will continue in group N.

Any updates on the R classes?

Or is the FIA meeting in September where all will be revealed about R4?

Both Subaru and Mitsubishi is talking to FIA about it, hope to hear more this weekend in WRC Germany

As a bit of a side discussion, how does the Evo 10 compare to the newest Impreza GpN for performance?

As the Evo 10 was a bit down on performance when it first came about with many sticking with the Evo 9.

[Mirek]

Evo X has by far strongest engine of all Gr.N cars but is also too heavy. That is it's main problem. I think that it's almost 100 kg heavier than Impreza or Evo IX.

[RICARDO75]

Armindo Araújo said that is car is now with less 100kg than before
