Awd

[zullard]

AWD, anyone have info on the R32-R34 AWD systems maybe we can use that info to guess what the GT-R will have...

[Tim]

don't the old skylines have the option to switch from 4wd to Rwd? I know i've seen them doing rear wheel drive burnouts....

[Skyline]

Skylines were available in RWD only (and also 4-door) variations...

[Tim]

you lie you f*cking guy!

[zullard]

the new GT-R is confirmed AWD correct?

[twenzel]

Yes, I beleive its 100% confirmed that it is all wheel drive with adjustable torque bias.

[GT-R]

any known numbers on the bias or the adjustablity options? old skylines were strongly rear wheel biased hope they keep that tradition.

zullard, its a electronically-controlled ATTESA E-TS all-wheel-drive system specifically developed for GT-R. The rear drive-biased system can vary torque split from 0:100 to 50:50 depending on speed, lateral acceleration, steering angles, tire slip, road surface and yaw rate. Of note is a special GT-R-specific yaw-rate feedback control, which measures the differences between the target yaw rate calculated from steering angle and actual yaw rate detected by the yaw-rate sensor and G sensor to adjust torque bias.

No they dont have the option but they did offer different trims back then. The GT, GT-S, and GT-R. They offered awd and rwd versions and they also offered oddly enough a NA version.

Well this is also a misconception because if the car is weight balanced or corner balanced to be even in distribution then its better for the car to be 50/50 as far as power distribution.

The power is deployed to the wheels via a 5-speed gearbox which is coupled to the Skyline's all-wheel-drive system ATTESA-ETS (Advanced Total Traction Engineering System for All - Electronic Torque Split).

The GT-R uses an electronically controlled all-wheel-drive system (similar to Porsche's 959). A 16-bit microprocessor monitors the car's movements a 100 times per second, including wheel rotation and lateral as well as longitudinal acceleration. When slip is detected at a driving wheel, the system electronically distributes torque from this spinning wheel to one without slip.

In this case the electronic AWD-system offers the advantage that actions are enacted much faster than by a viscous-coupling-system (we're speak-ing of hundredths of a second here). In standard setup, ATTESA-ETS distributes the torque to the rear-wheels, but when slip is detected on one of those rear-wheels, it can distribute up to 50% of the torque to the front wheels, i.e. it can adjust the front/rear torque-split from anything between 0:100 to 50:50. Among the rear-wheels, an active LSD can further distribute the torque from one wheel to the other if necessary. Due to this setup, the Skyline GT-R can even drift, although it is an AWD car.

The new Nissan GT-R uses probably the most advanced four-wheel drive system on a road car ever used. The all-wheel drive (ATTESA E-TS) optimally distributes power to the front wheels when and if necessary. Though naturally rear-drive biased, up to 50 percent of torque can be fed forwards improving traction in difficult conditions - such as rain, frost, ice or snow. Front drive is also utilized to improve cornering performance on tarmac, improving traction and stability.
Special computerized control automatically alters the front/rear torque split from zero torque at the front wheels, to 50 percent of total torque. The control is varied continuously, as various sensors on the car measure speed, lateral and transverse acceleration, steering angles, tire slip and other road surface and yaw rate.
On the new Nissan GT-R an additional sensor is the yaw-rate feedback control, which measures the difference between the target yaw rate calculated from the steering angle, the actual yaw rate detected by the yaw-rate sensor and G sensor. Front and rear torque is automatically corrected accordingly.
The four-wheel drive system includes a Vehicle Dynamic Control (VDC-R), the Nissan GT-R's electronic stability control system. This continually monitors the vehicle's behavior. If off balance behavior is detected - such as sliding or skidding - torque to the wheels will be altered to help stabilize the car. Electronic traction control is also fitted to rear mechanical limited slip differentials, preventing wheelspin and improving grip.

Hope this info helps.
