Specifications of Rallycars

[Lousada]

In the Atkinson thread there was some confusion about the dimensions of WRC cars. People said that the C4 was a smaller car than the Impreza even though it has a bigger wheelbase.
I just found out that searching for something as simple as dimensions gives different results all over the web. So maybe it's a good idea to collect technical specifications here, and discuss about various technical aspects?
There aren't any technical threads here at the moment but people keep referring to technical facts and 'facts'. I hope this will improve the knowledge of the forummembers and raises the general discussion here? Of course older rally cars are also allowed. Any thoughts?

I start off simple with dimensions of rallycars I've just been looking at. I added some older cars for perspective.

The longer the wheelbase is, the more stable is the car on straights.

[White Sauron]

By the way, the width of the Focus 06 (thre's no 07 yet) is 1800mm.

[L5->R5/CR]

most all of the current WRCar fleet is 1800mm, that is the maximum allowed width...

[Daniel]

The Skoda length must be wrong. The minimum length of a WRCar is 4m.

Thanks for showing that the C4 is not a "smaller" car than the Impreza in handling terms.

Yes, the lenght of stock Fabia is 3970 mm. But the homologation of Fabia WRC is based on model RS, which is long 4002 mm.
