who's got one of these fitted,

"in exceptional circumstances" - ie. both front wheels are clamped :)

good to finally see a readable version of that advert though...

Shame there isnt a better more up market version of the jacket that the OC could sort out. The MLR boys and gals seem to have it nailed.

To be fair it would bring in some revenue that could be used to finance other features of the club, the way "other forums" have run the club is more of a business venture, sometimes that is what is needed to move things forward and for things to evolve into a much better version, IMO of course :lol:

Looks to me as though all the logos on that jacket have been ripped off the modifiers site. Cheeky bastards.

Copied directly from wikipedia:
The 'mechanical' ATTESA system was developed for transverse layout vehicles and introduced with the RNU12 Bluebird in the Japanese market, entering production in September 1987. The system ran right throughout the U12 series (RNU12/HNU12) and was fitted to numerous U12 models with differing engine and gearbox combinations. An almost identical system is fitted to the RNN14 GTi-R Pulsar and the HNU13 Bluebird, finding usage in numerous other nissan models.
- Basic mechanical version of ATTESA.
Not to be confused with ATTESA-ETS:
The ATTESA-ETS layout is more advanced than the ATTESA system, and uses a 16bit microprocessor that monitors the cars movements at 100 times per second to sense traction loss by measuring the speed of each wheel via the ABS sensors. A three axis G-Sensor mounted underneath the center console feed lateral and longitudinal inputs into an ECU, which controls both the ATTESA-ETS 4WD system and the ABS system. The ECU can then direct up to and including 50% of the power to the front wheels. When slip is detected on one of the rear wheels (rear wheels turn 5% or more than the front wheels), the system directs torque to the front wheels which run a viscous LSD. Rather than locking the AWD in all the time or having a system that is "all or nothing", the ATTESA-ETS system can apportion different ratios of torque to the front wheels as it sees fit. This provides the driver with an AWD vehicle that performs like a rear wheel drive vehicle in perfect conditions and can recover control when conditions aren't as perfect. The advantage to a more traditional ATTESA (Viscous LSD) system is response in hundredths of a second.
Furthermore:
The Nissan Pulsar GTI-R (chassis code RNN14 - aka GTiR, i-R and 'R) is a special vehicle that was manufactured by Nissan between 1990 and 1994 in order to enter the WRC under Group A rules. The body is based on the Nissan Pulsar (aka Sunny) N14 3-door hatchback model, but features a large rear wing and bonnet scoop. It has an ATTESA 4WD system (also used on specific U12 & U13 Bluebird models), and a unique variant of the SR20DET engine (not used on any other car).

Howzat!?

Clicking on the word "Reference" in my first post would have brought the same information up.

Yes there is; it's just a very basic, mechanical version.

if you look here;

"Quite similar to offerings from other manufacturers, drive passes from the gearbox to a centre viscous limited slip differential, in to a transfer case splitting drive to a co-located front differential, and tail shaft connected to the vehicles rear differential."

on your link george you'll find that even this explanation is wrong as far as the gtir is concerned, there is no centre viscious lsd on most gtirs, hence why i said that theres no- Advanced Total Traction Engineering System for All-Terrain!


traction cannot be varied from front to rear dependant on road conditions. UNLESS you fit the centre lsd as mentioned.

I thought that we had a centre differential for that purpose (housed in the transfer case?), and that the centre viscous LSD would minimise the torque split and allow for less variance between the front and back... making it closer to the 25% of power to all wheels. So a non-viscous coupling would actually be more free to split the torque un-evenly between the front and rear.
I think the viscous centre diff was a Nismo rally option.

I don't dispute that you know more about this than me, I'm just saying that I've always seen the all-wheel-drive system used by Nissan referred to as ATTESA; the fact that Nissan used several different versions of it and called the all ATTESA just confuses the issue. - Maybe it was just the rally spec'd models that can legitimately claim to be ATTESA.

i wasnt trying to make it look as if i knew more mate, all i was saying was it cant really be called attesa when theres no centre lsd.

looks to me like nissan just used it in publications anyway to make the cars look better spec'd than they actually are/were!
