They could make a car with 12 wheels and 4 engines, but if it doesn't have something to get all the power to the ground it is irrelevant. The Nissan isn't even full-time AWD so quit acting like it is and like it is poison, just because something is american doesn't always mean it is right. If anything, the new Corvette should have a similar setup with a switch to keep it just RWD if you want.
If you want information about Nissans AWD system here you go:
ATTESA-ETS (GT-R version)
The 2009 Nissan GT-R uses an updated version of the ATTESA-E-TS, and is designed to work with the car's rear transaxle layout. The system is unique in a way that it utilizes two driveshafts under the vehicles centerline, with a second driveshaft runnng slightly to the right of the main driveshaft and engine sending power to the front wheels. It is so far, the only rear transaxle-based AWD system for a front engined car in production.
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 rear torque split can go from 2:98 during a standing start to a maximum of 50:50
