I've done a search and couldn't find any threads...can someone tell me the difference between Subarus AWD and any other 4WD system? remeber the Subaru advert on Eurosport that had a man for 2WD, a horse for 4WD and then a cheetah for AWD. Is there really any difference?? thanks v much

 

Anyone???? ..... i would like to know some tech stuff on our 4WD system ..... torque split front to rear, are LSD used etc .... someone must know ?? ... pleeease

 

Its quite simple really
AWD cars are designed as a permanent 4wd from the beginning, a 4wd car does not necessarily begin life as that (there are 2wd variants and then the 4wd variant came along).
This is basically the difference (and the fact that there is no transfer box for 2-4wd).

LB4,
The transfer of power to front/rear depends on variant of scoob, there are lots of differences depending if its a UK turbo, an STi, type RA etc as some have mechanical diffs, some have vicious diffs etc.
John Felstead is probably one of the best to tell you how these work, im not that techincally versed in these things

I think this is right but i'm a neewbie so dont hold me to it.

A standard UK or WRX model will probably have a 34/66% front to back torque split, as this is what most manufacturers seem to set AWD at.

Standard UK' s& WRX's have viscous coupling rear and centre diffs and an open front. Some of the STI's have plate type rear's and viscous front and centre.

 

Thanks for that Tony and Monkey ..... Just like to know these technical things .. hehehhehe ... my car is a UK spec by the way.

Cheers
