Have the rules actually been finalised yet?

yes, PLuto wrote it already on dec 29th.

I cant wait see the car driving the first time!

There are people on other forum that are saying that the basics og the regs are done, but there are details missing from the regs. And thatmthose missing details are the reason that Peugeot are giving pri to R2/R3T and the two shells meant for R4T is standing still developmentwise.

Can anyone confirm or deny this, that the complete R4T regs are not done yet?

208 R4T development definitely isn't standstill. The reason R2 is development is faster is that it's much simpler car based on existing C2 R2.

It’s going to be interesting to see if all the updates allowed in R3/R3T plus the 4WD kit can be implemented in the R4T within a reasonable cost.

Already the switch from a 6-gear gearbox that S2000/WRC is using to a 5-gear gearbox could save some costs. At least this is the case between R2 (5-gear) and R3 (6-gear).

The spare part price for a 5-gear R2 gearbox is between 4700 € (Fiesta R2) to 5700 € (Fabia R2). For a R3 (Renault Clio & Honda Civic) 6-gear gearbox the spare part price is about 9000 €.

By this the R2 5-gearbox is about 42% cheaper compared to a 6-gear R3 gearbox or the price of a 5-gear gearbox is about 58% of the price for a 6-gear gearbox.

Another would be if the engine could be kept standard but would the standard engine cope with a power increase from about 150 hp to about 300 hp.

Makes sense, does your scources also tell you that all manufacurers have recieved a 100% complete and approved by FIA set of R4T tech regs to build from ?

But the R2 gearbox is also built for smaller torque than the R3 one. That's not the case of R4T where it will have to cope with much higher torque than in R3T (if they switch from 29 to 32 mm restrictor with otherwise similar engine). Less gears mean less parts but I think there will be higher stress on them due to bigger steps between gears. Current X-Trac gearbox for S2000 costs around 20 thousand. Let's see...

the difference in price between the 5speed and 6speed gearboxes isnt just the 1 gear more.There are other points make them much more expensive.
Torque they can cope,sequential or not, casing oem or new cast,how many sell them etc.

[OldF]

OK, my comparison was too straightforward. Any idea how much the higher torque vs. one more gear explains the price difference?

To be more precise I should also have said:

“Another would be if the engine could be kept standard but would the standard engine cope with the higher torque”.
