just get a picture of each and compare the differences urself. im sure it will be easy. the GTR is the meanest and baddest looking. anything else is an imitation and doesn't need to be taken seriously hehehehe

The R32, R33, and R34 GTRs are all 4wd. They all have the ATTESSA system which allows the car to crusie around in 2wd until you begin to accelerate. in which case the ecus take readings of G-force sensors, throttle position sensor, and the anti-lock brake cogs. It then applies front wheel torque based on the needs or what it precieves are needs. So it is veriable in the amounts from 1% to 50%.

from what i understand it most definitely is. not least due to its 4-wheel steering system
Yes, it rather is. The Subaru and Mitsubishi systems are active only in the mechanical & hydraulic sense. It's only based on differences in torque or wheelspin. Nissan's ATTESSA is connected to everything: speed, direction, wheelspin, braking, suspension compressions, throttle position, RPM...everything. More info can probably be found:

It is hard to explain without being able to show you guys. But in a nut shell here it is.
The R32, R33, and R34 all have ATTESSA systems. Each system was refined in the following models. While the r32 has the most primative (if you will) where the clearance in the clutch packs in the transfer case is greater than that of the R33. Th R32 also takes a sampling rate of 100 per sec while the R33 Vspec is 1,000 a sec. Thus react quicker. The ATTESSA Pro system on the R34 is even more responsive than that of the R33 model.
In essence, fact and reality the R32 when cruising or very mild acceleration it is only in 2wd. Thus when tuning simply removing the 4wd fuse is not an issue. If run like such for an extended period of time you risk over heating the clutch pack in the transfer case though. A major draw back to this system is if you have not been able to engage front wheel torque before a turn, turns into a slide you will see the car react like a RWD car. I have done a 180 right in the middle of a street like I could in say a camaro. That is due to the R32 (non-vspec) not having a latteral G-force sensor which began to come out in production in late 93 with the Vspec and 94 Vspec II.
The R33 seems to apply front wheel torque much sooner (to be expected) with less effort. How ever this causes a lot of problems for tuners. Since simply removing the fuse to disable the 4wd system will cause the clutch packs to over heat and burn out you can do that. You have two options now. 1. Remove the front drive shaft or use a 4wd dyno. The latter is not practical for tuning because of the stepping in dynos causes the front wheel torque to fluctuate. It also has a very reactive latteral G-force sensor along with the longitudal one in the center council.
This system was again refined further in the R34 GTR, GTR Vspec and Vspec II.
The Attessa system is a unique and can be a hard system to understand. The major advantage of it though is less strain or throttle is needed to get the car moving as compared to a full time 4wd car like an EVO, Subaru etc. In turn due to the extra amount of gear needed weight becomes an issues hence the heaviness of the car comparted to a EVO.
Many times I am able to get up to legal road speed without seeing the front wheel torque split gauge needle move. Generally it takes about half throttle or more to get it up to over 2% which is stuff all in the bigger picture. Cruising it sits on zero.

The Mitzi and Subbie were designed as Rally cars and nothing more. Thus they will have a 4wd system simular to those found on a 4X4 truck there in the states. Not exactly but the same principle.
The 4wd systems would have had nothing to do with one over taking the other. Fact is given equal drivers and equally standard to modified cars the GTR would eat both the Evo and WRX up for lunch and spit them out on asphelt, while in the dirt it would be like a whale out of water.

since we're talking about 4wd systems, does anyone know the merits of the audi quattro system? they were the first to put 4wd in rally cars and now have a company called Quattro gmbh. if im not mistaken. anyway it is very highly acclaimed and i was wondering if it uses any extraordinary electrical technology or is it just excellent mechanically?
