In EVO torque goes from gearbox to the central diff, and the diff splits it between front and rear. In S3 The tourqe goes directly to the front wheels and to the haldex coupling, which can put it through toi the rear wheels or not.
A minor packaging difference of components which is not evident on driving
The ACD unit sit after the front axle gearing, and can cut all power to the rear exactly as the haldex can
Anything in this chassis is OK. Can you give me these examples?
As I mentioned in my first post, I am not interested in theories. Have you driven such a car or you just certain because this is your opinion?
A Finnish chap called
Jani Vainikka has rallied an
Octavia 4x4 competively vs Evo a few years back
This was built from a stock production car, its not one of the the Skoda Motorsport/Prodrive Octavia EVO series of cars - Skoda motorsport make a lightweight WRC Homologation chassis which can then be made into either a WRC Prodrive 4x4 car or a 2WD Kit Car
The Octavia WRC cars are still PQ34 chassis, and still have a 20v engine so they count inmy book
and of course my own car - octavia 4x4 - Peloquin torsens Front and rear - currently on blue haldex
Developed against a Mitsubishi Evo 9 MR 360
Both cars circa 250bhp/tonne
TBH The difference between the two cars in now down the suspension, not the drivetrain
My setup work on my is carried out by a wily old rallycrosser with many yrs of experience, my cars better setup, feels much more planted and soaks up the terrain better
There's TT rally series in Canada too,
typical car spec
I don't think it's the main reason. The active diff make much of work of a driver. They wanted to force drivers to use their brains to drive rally cars, not the computers to do the whole torque vectoring etc.
That's the 'official' press version
They could have gone back to purely mechanical setups like the rallycrossers and the pre-group N cars
But instead they went for diff'less with clutched rear axled - a setup purely designed to be harder to drive - eg more oversteerand more dramatic action
WRC in in viewing battle with the various Rallycross series
Lots of good young drives are heading into Rallycross vs stage rallying
ps
In the later PQ35 chassis (8P) - one of those won the 2008 MSA Asphalt stage rally series
-well it was a 8P chassis anyway, may not been much of the rest of the car left ..
