GTR 4WD Vs Subaru AWD??

[Ethan_R32]

Hi guys,

just wanting to know the main differences between the GTR's 4WD versus the subarus AWD? Ive heard that the subaru is a constant 4wd, making the power loss greater after the initial traction loss. And whats with this symmetrical AWD thing anyway?

I think this symmetrical thing is trying to show that subies have very good balance. GTR's 4WD lets the rear wheels kick out before the front wheels come into action. Takes a little getting use to at first, but it's quicker once you get the hang of it.

The symmetry they refer to lyes in the drive split between the front at rear. For instance the late Ford TX3 4WD's had more drive to the rear than the front, making it a pretty fun car to drive (i think it was 35/65). Where as the WRX's have a 50/50 split, and while this is symmetrical and balanced, its also boring. As many RWD owners will tell you "Symmetry creates understeer"

Attessa is a brilliant system, it has to be said, keeps the car heaps of fun to drive, whilst having the advantage of 4wd when you need it. Think of it as a variable split which only delivers front drive when theres traction loss.

The problem with attessa is that it is relatively complex and expensive. It is a fully electronic system than can vary the split from 50/50 to all RWD. Other lesser systems are totally mechanical 50/50.

Clearly attessa is the best and who says that owning a Skyline means compromising on engineering?

ATTESSA is also conected to a lateral G-force sensor that also determines the split transfer too!!!

Sometimes you control ATTESSA and sometimes ATTESSA controls you!!

Red17 has got it. 50/50 split will cause understeer simular to a front wheel drive car. And we all know that front wheel drive cars are for people who can't drive LOL....... ie. the WRX driver :lol: :lol:

I read somewhere (I think it was Autospeed), that the reason they set up cars to understeer is because of the dummy factor !!!

The comon driver doesn't know how to control a car in oversteer, but any dummy can control and get out of a situation that has understeer - you just take you foot off the go peddal.

And taking your foot off the go pedal is apparently a natural reaction for 90% of drivers when they loose control of a car.

then theres breaking....and breakedges

The GTR's electronically controlled AWD driveline (ATTESSA) is brilliant - far more rewarding and technologically advanced than Subaru's AWD system. Torque split is biased 100% to the rear wheels until the rear tyres break traction , then the bias varies to a max of 50/50 front-to-rear gradually fowarding torque to the front wheels. This makes the GTR bloody fast on launches as initial slip at the rear tyres prevents the engine from bogging down through too much traction, and the front wheels provide wickedly quick drive for rapid acceleration.

haha.. yep.. that'd be ME!

and i'm pretty sure its spelled ATTESA... with 1 S
