As VW has said that they don’t even make a RRC car at this moment. Focus on WRC and it’s looking very promising.

No we have just to wait and see what’s coming.

You where faster Mirek, but anyway I post my own version.

Afaik R-group cars replace A & N group cars. I believe that no new group A & N homologations are allowed anymore, only upgrades to the...

First time I heard (read) about this new formula was in gpweek (page 39, issue 121 20.7.2011)
By this it will be 1600 cc direct injection.

Provisional group5 regulations has been published 20.7.2012.

Some info about Peogeot 208 R2.

Now also the Twingo should be competitive with the other R2s.

190 bhp & 180 Nm

Updated homologation form for the Subaru R4 and also a spare parts catalogue.

With quite small changes there seems to be a way increase the suspension stroke in the front.

Subaru R4 homologation forms.

Looks like Subaru have the R4 suspension arms only for rear suspension.

Oh s**t, I forgot the Fabia. 180bph.

That’s true. The most powerful R2 is the C2 Max with 190 bhp, the second one C2 Base with 185 bhp, third is Fiesta with 168 bhp (with 97 octane fuel) and finally the last one Twingo with 160 bhp.

I got curious about the differences in the prices. The calculations took some time to make these calculations but here are my results.

A complete Fiesta R2 from M-Sport is 48.955 € (exchange...

Nice spare part list where the serial parts and the kit parts are clearly separated.

Thanks Dimviii,

It was nice to see (and of course to hear) the comments of the drivers who’s did the test. The test drivers’ comments about this R4 improvement are encouraging.

I...

I listened yesterday to Total Rally broadcast from last week and there was some talk about R4.

The guy interviewed (George Donaldson, STI, general manager of motorsport projects or something...

I suppose the Mitsubishi will have longer suspension travelling with the new kit but how much?

Yes.

R4 rules are published. The R4 rules are part of article 260 on pages 24-26.

It’s 33 mm from beginning of 2010. Renault is little down with power compared to other N4 but it’s only FWD so 266 bhp is probably enough.

Here....

Thanks for the compliment. :)

We work as a team. I ask the questions and Mirek give the answers. :D

Thanks Mirek.

I dug up and old book that I bought when I was a young boy and did some reading. Now I’m more aware of what you wrote.

You know, the physics haven’t changed at all...

I’ve understood that the brake pads for group N can’t be bigger than the original ones and using bigger brake disks won’t change the braking power but there must be some reason for using bigger brake...

This could also be put this way.

Class WRC: 1.6T engine + WRC kit
Class 1: S2000 with 1.6T engine
Class 2: R4 and S2000 with 2.0 NA engine
Class 3: N4
Class 4: RGT
Class 5: A7,...

IMO the biggest problem with N4 is the driveability that is caused by less suspension travelling compared to S2000 and too small brakes vs. the weight. If the upper suspension attachment point can be...
