[WRC] News & rumours (part II)

Rules were not revealed for public yet but I believe it was meant to be something like R3T car with standard 4WD transmission and larger restrictor. No special wide suspension like in S2000, no bodykit, production-based engine (no direct injection required) etc.

It will be good to have something 4wd and cheaper than S2000 or RRCs but I am worried these cars will be too boring to watch like R3T or N4 cars. Any ideas on the minimum weight?

Yes, every car can be spectacular but there are different starting points.

Of course the width of the car doesn't directly affect the spectacle, but the looks, sound and handling of the cars undoubtedly have an impact on the attractiveness of our sport.

I do welcome the FIA trying to create a formula for a cheap(ish) 4wd formula though for manufacturers without a suitable road car.

Looking at the group A cars in the beginning of 90s, they were spectacular without any wide body shells.

I’ve seen spectacular driving with N4 cars but the sound. The sound doesn’t match how the cars are driven and that is why they look boring sometimes.

I think the new R4T cars will have a similar 4WD-system as S2000 and WRC cars (no central differential, 5-speed gearbox instead 6-speed as for S2000 and WRC)) and if they have enough power and not so high boost, the revs and the sound will be there. Even if the boost would be at the same level as the N4 cars have, their peak power would be on higher revs due to smaller engine capacity.

Bring in 18000 RPM rev limiters :laugh:

And the rally cars would sound like a flock of bees. No thank you. :)

I heard that most likely the restrictor size will be set to 32 mm. Now the R3T cars have 29 mm so with same boost we can expect reasonably higher rpm (I guess around 2 thousand more).

If DS3 R3T has 235 Hp with racing fuel than the estimated power of same engine with 32 mm restrictor could be around 280-290 Hp.

I couldnt care what power they have, my tractor at work sounds better and is more entertaining than these. Boring cars like the turbo Ds3s are bad for the sport....

See the first sentence. With such larger restrictor and presumably same turbo the rpm will be much higher and therefore also the sound much different.
