ATTESA ETS

Four-wheel drive
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.
