New R4 Car - Think Tank

[Sulland]

As it is said in other threads, group N4 has been used by many as their first 4wd car. Many has also continued with it due to prices compared to R5 and WRC.

There is a hole in the system now that N4 and N4+{R4} is dying, and it needs to be filled!

How should a budget class 4wd car look like technically to become the logical stepstone from 2wd to 4wd?

Trouble is, if R5 was cheaper that would fill that gap. Small cars, low (relative to WRC) power and a bit of simplicity built into the rules. But it would also need WRC to be much more than it is nowadays. Bigger cars, bigger engines and more variety.

If someone were to make a 'watered-down' version of R5 could it be made cheap enough? I mean if a manufacturer made an R5 car that wasn't to the same level as the rest but cheap and reliable, they could make a whole fleet of them for a one- make championship below they R5 class.

The swedish R5 project is mostly mitsubishi evo parts. Can a rule, that alows privateers to build existing evo/wrx sti parts into a selfchoosen chassis, be something?

Here in South America I think that the Maxi Rally solution is good, considering the economic situation we have here, in which bringing things from outside is really expensive (Brazil and Argentina is like that).

They use the same engine, transmission and diffs for all cars, only the chassis and suspensions are free. In that way, they have a cheaper option for a 4wd car, and some more manufactures can support teams.

Which engine, transmission and diffs is used there?
I think that should be a interesting formula for privateers here in europe.

During last Rally argentina, I read an interview of the ingeneer working on MR that FIA was looking to adopt it to new N4 categories (maybe with some change).But since, nothing new ...

For me, FIA just think to let people homologate the car they want in N4 category (with technical rules of course), as it's for RGT now. N4 are important in a lot of country. It's a good market for teams like Prodrive f.e. to develop a car. But today you need the agreement of the manufacturer ... and most of them don't care about N4, R3, R2, R1 ...

Threads for the two sudam categories here:

But Fia Is also looking to downsize when you see the neu R1-R3 rules and turbo rules and reg.

But I like the concept of a private tuners class!

Here in Brazil the XRC uses a Chevrolet V6 engine, but the idea was the same as the Argentinean Maxi Rally cars. But here, drivers still think it's expensive and, besides that, there are still some reliability issues.

I heard that the Baratec team was working on a project to use a 1, 6 liter, turbocharged engine on the Maxi Rally car, and that would make easier to get a Fia homologation. Don't know how far the project is right now...

Baratec are working on a 1600T project.

The site does not tell much on status of the project. Anyone that knows?
