The current hybrid 4WD are just a mockup of real 4WD. It's marketing stunt which obviously work as You believe in it...

Those cars You speak about are simple 2WD with a part-time availability of pseudo-4WD. The problem is that front and rear wheel drive are not connected and the electric engine for the helping function is just too weak. If You for example stand in a hill and the front (combustion engine powered) axle looses all traction You have only the electric engine in the rear to move all the car which in some cases is not enough to move the car at all (in steep uphill for example)! It also has not enough battery capacity to use the electric rear axle for reasonable time (don't know if cooling allows that anyway). It's just helping system for occasional troubles of common users, nothing more.

None of those cars is electric powered full 4WD car with combustion engine working only as generator which is the only way how this could work for permanent use (basically like in a diesel-electric railroad engine). For WRC use there is also big question of reliability and safety of the electric systems in WRC conditions. It's not F1 or Le Mans but there are water splashes, mud, sand etc. everywhere.

I heard next year Tom Coronel will try to finish Dakar in full-electric variant of McRae buggy. Than we'll see if the electric systems can survive use in real tough conditions (not speaking about the need to change batteries in stages).

If You believe that design of WRC-suitable hybrid or electric system is cheaper than the S2000 You are very very naive. Absolutely no way. Plus with full electric cars You would have to change the format of rallies completely to allow them changing batteries between stages (likely to forbid very long stages at all).

Provisional group5 regulations has been published 20.7.2012.

I started to wonder if the rear suspension is going to be original (front and rear axle suspension). I couldn’t find any mention of modification of the rear ala S2000 & WRC. If the car has a torsion beam rear suspension, is there room for the prop shaft? Some modification must probably also be made to the body shell to make room for the rear diff.

Engine: 1.6L or what ever?
I didn´t find "engine max XXXX cc"

[HaCo]

Does this mean the body will not be widened?

900-f

Overall width
The maximum width of the VR5 car is 1820 mm

[HaCo]

The 208 is 1730mm width. So, 10cm left, how much is the current s2000 spec?

[Mirek]

1820 mm too (for example stock Fabia II is only 1642 mm).

[polo10]

1820 mm too (for example stock Fabia II is only 1642 mm).

Hi Mirek, i know that the new Fabia will only be on the market in 2014, Are you sure that R5 will be based on the Fabia?

[Mirek]

I can't say I'm sure but I'm willing to bet Citigo is nonsense and there is no other car to make it from. I heard the R5 will be homologated only for season 2014 anyway.

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.




In the provisional R5 regulations 324-a1 it says:

Any additional injection system (i.e. water …) is prohibited.
Injectors:
For direct petrol injection, at any point of the fuel circuit, the maximum pressure authorised is
8 bars in the low pressure circuit and 200 bars average on one cycle in the high pressure
circuit (direct injection only).

Could be interpreted that a non-DI engine is also allowed.

Cheaper Super 2000 category planned

The new-generation Super 2000 cars will be half the price of a current version according to Peugeot Sport’s Bertrand Vallat.

Vallat, who is responsible for the French make’s hugely successful 207 model, revealed that Peugeot and Skoda are in discussions with the FIA, motorsport’s world governing body, regarding the new technical regulations for 2013.

In an interview with respected radio reporter Colin Clark, Vallat said: “Skoda and Peugeot are talking with the FIA for a new car from 2013. It will be a standard car with a 1.6 turbo based on a future model. We are trying to cut the technical cost by half. It will be a big challenge to reduce this cost but we will be working hard with the FIA to achieve this. The category could be good."

The current Super 2000 rules were introduced in 2006. If the cost-cutting plans reach fruition then the new-era S2000 machine could cost approximately 100,000 Euros.

PS I don’t believe the price will be as low as 100.000 €. I don’t you can get even a Citroen DS3 R3T for that price.
