Although this is not part of the AWD system, the computer makes use of the same sensors to determine wheel slip and traction. On ATTESA E-TS Pro equipped vehicles, the front differential remains a standard differential, not being linked to the ATTESA E-TS Pro system. The R33 Skyline regularly updates the speed of the rear wheels to the wheel speed sensors 100 times per second while the R34 Skyline regularly updates the speed of the rear wheels to the wheel sensors 1,000 times per second. The 2009 Nissan GT-R uses an updated version of the ATTESA E-TS, which is designed to work with the car's rear transaxle layout. The system is unique in the way that it utilizes two driveshafts under the vehicle's centerline, with a second driveshaft running slightly to the right of the main driveshaft which transfers power to the front wheels. Unlike the previous ATTESA systems which relied heavily on mechanical feedback, the system in the GT-R uses electronic sensors and hydraulically actuated clutches. It also has a yaw-rate feedback control system, effectively managing slip angle. Front-to-rear torque split can go from 2:98 during a standing start to a maximum of 50:50  ATTESA E-TS system is used in the following models:  ATTESA E-TS Pro system is used in the following models:
