The Advanced All-Wheel Drive System Of The 2017 Cadillac XT5: Feature Spotlight

Standard models of the 2017 Cadillac XT5 send power to the front two wheels — a traditional setup thats not all that exciting. What is, however, is the optional all-wheel drive system.
Utilizing a “twin clutch” design, the new system continuously and automatically delivers outstanding traction in various driving conditions. Cadillac says that the system was specifically engineered for strong performance in wet, snowy, or icy conditions, while also being capable of providing enhanced stability in dry weather.
The twin clutch design allows the XT5’s AWD system to transfer up to 100 percent of available torque to either the front or rear axles. In addition, the system’s electronically-controlled rear differential can direct up to 100 percent of available torque to either wheel laterally. The ability to move power across the rear axle was designed for “split-coefficient” surfaces, such as when there is more water, ice or snow on one side of the road surface than the other. In this respect, the system is similar to the AWD system of the new Buick Envision.
Furthermore, the Cadillac XT5‘s AWD system is driver-controlled and includes a new “disconnect” feature that disables the rear drive unit, thereby leaving the car in front-drive mode, for improved fuel efficiency and reduced emissions.
We’re eager to experience the system in action for ourselves when the 2017 XT5 launches in the spring of 2016.

If the system is driver controlled, I wonder if one can shift 100% of torque to the rear wheels, thus making it a RWD on demand?
From the way we understand it, the system is only driver-controlled to the extent of enabling and disabling it. Power delivery remains an automated function of the vehicle.
One can dream…Thanks for clarification Chris.
Didn’t the Oldsmobile Bravada have a similar setup with the Smartrak !?
Yes, but that was a truck chassis… this is a car chassis, and is a completely different system.
Who is the system sourced from? One of the Haldex setups was used in the SRX, right? I believe all modern (ie GM) Saabs used Haldex too.
If I read correctly, It’s from GKN driveline, the same company supplying the AWD drivetrain for the Ford Focus RS
I actually work for the company that makes the AWD system for the new XT5, at the facility that manufactures it. It’s really cool and definitely as high tech as almost anything else available on the market today.
Wow,
Sounds like they have caught up to the AWD system in the 1979 AMC Eagle!
AMC soon moved to a state of the art, 42-disc New Process Gear NP119 transfer case. Both transferred power to the wheels with the most traction. The full time four wheel drive system, dubbed “Quadra-Trac,” was co-developed by AMC/Jeep and Chrysler’s New Process Gear. It used a viscous coupling in the center like a Chrysler Pacifica able to send 100% power to the front or rear, then it had a manual locking rear only
