AWD vs. 4WD vs. 2WD, oh my!

WHAT IS ALL-WHEEL DRIVE (AWD)?
Nissan’s Intelligent AWD is designed to help maximize efficiency, by sending power to the front wheels while at speed, and adapting to transfer power between the front and rear wheels when a change in road conditions is detected, making it more economical on the highway. This feature makes it a great choice if you live in an area with heavy rain or snow, or you plan to take your vehicle for light off-roading. All Wheel Drive (AWD) has become a popular choice for many reasons, including its versatility and ability to anticipate and adapt to changing road conditions, by sending power to all four wheels, or just two. AWD gives you the control of Four-Wheel Drive (4WD) with the efficiency of Two-Wheel Drive (2WD).
Nissan’s Intelligent AWD system [] gives you the most traction and power while driving. AWD vehicles are equipped with a center differential, which is composed of gears that split power from the transmission to both front and rear axles. Wheel sensors function to detect traction loss, indicating which wheels require additional power.
AWD isn’t just for rugged off-road vehicles either. The Nissan GT-R is equipped with an ATTESA E-TS AWD system, which helps to distribute torque to front and rear wheels, depending on tire slip or changes in road conditions. The ATTESA E-TS system functions a little differently, using two driveshafts to split power to both front and rear wheels. The system is rear-wheel biased, but torque can be split between front and rear wheels in an instant.
How Does All-Wheel Drive (AWD) Work?
All-Wheel Drive (AWD) vehicles are equipped with a center differential, composed of gears that split power from the transmission to both the front and rear axles. Alternatively, it can send power to the front wheels only, creating a more efficient drive.
START WITH ALL FOUR
The second you pull away, Available Intelligent AWD turns on, delivering power to both front and rear wheels for improved grip.[]
CRUISE WITH JUST TWO
Once you’re up to speed, no sense powering all four wheels, so Available Intelligent AWD efficiently sends the power all up front.
CORNER WITH ALL FOUR
For enhance cornering control and traction on curvy roads, the Available Intelligent AWD compensates by transferring some of the power from the front to the rear wheels.
