So what you are saying is that the R1 class is useless on gravel ?

Mirek,

LSD stands for limited-slip differential? If yes, why you say that its absence is the problem for gravel?

Mirek,

Cause the inner front wheel will use all the power spinning through bends, and little power, of the little power the R1 has available will drag the car forward.

Ah, ok then, it's a problem for the R1 cars then, right?

I asked that because here in Brazil probably 95% of the front-wheel drive cars doesn't have LSD. For example, in the National Championship I think it was last allowed in 2007. And there's the Peugeot Trophy too, and we don't use it.

Thanks for your answer.

When kit contains what it contains currently - I think yes.

The R1B is very close to Finnish V1600 class (V = vakio = standard).

The model of the car must be 2000 or newer. FIA homologation (group A or N) is not mandatory but the car should be available in EU. Every car must have a passport (homologation form), which is filled by the competitor. The application for a passport is send to the local ASN.

The min weight for the cars is calculated with the formula 525 kg + 6,8 kg/kW. For a car cylinder capacity of 1500 cc or smaller the formula is 500 kg + 6,8 kg/kW. If the car has a 6-gear gearbox the formula is 550 kg + 6,8 kg/kW. The kW is the power given by the manufacturer.

In rallying this is the min weight without driver and co-driver but in rallysprint and circuit racing it’s includes the driver also.

The main difference is that in group R the dampers must be homologated as in the V1600 they’re free except only dampers with only one adjustment are allowed.

Here is a list of cars that have a passport (situation 2.2.2010)

Alfa 147 (4), BMW 316 (2), Citroen C2 (2), Citroen C4 VTR, Citroen Saxo VTS (2), Citroen Xsara VTR, Fiat Bravo (2), Ford Focus (3), Lada Samara, Mitsubishi Colt, Nissan Micra (2), Peugeot 206 XS (4), Peugeot 106 GTI (2), Renault Clio (5), Renault Megane, Skoda Felicia 1,6, Suzuki Ignis Sport (2), Suzuki Swift Sport (2), VW Golf, VW Lupo GTI, VW Polo (2)

very nice idea with this V1600. If google translates correctly gearbox have to be standard? So no LSD allowed? What are the safety rules? Of course the rollcage according to appendix J but what about seats, belts, extinguishers? - up to date homologations necessary or could be with expired homologation? tires are free?

[OldF]

That’s correct, the gearbox has to be standard and no LSD allowed. If the standard has a LSD, it must be removed or the differential replaced with a differential without a LSD.

The seats and seat belts must be FIA approved. The tires are free. A car that have an expired homologation or a car that even ever had a homologation can be used as long as the model in question is newer than year 2000.

You can find the regulations here V1600 regulations and make a google translation of them. I would have posted them here but there were over 10.000 characters so it wouldn’t fit in one post (I remember that the 10.000 character is the limit for one post).

Thanx for explanations!
