    So I have a 2008 CTS4. I was wondering if the AWD is always on or is in 2wd. If so is the rear wheels getting power or front and is there way to activate the AWD?

    The following is from my 2011CTS owners manual, 2008 may be the same:

    All-Wheel Drive

    Vehicles with this feature always
    send engine power to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions.
    When using a compact spare tire on an AWD vehicle, the system automatically detects the compact
    spare and disables AWD. To restore AWD operation and prevent excessive wear on the system, replace the compact spare with a
    full-size tire as soon as possible.

    Re: Awd?

    For dry driving, it seems to shuttle most of the power to the rear wheels, so it kind of feels like a rear-wheel-drive car, but when it needs more traction, it directs power forward as needed. It's all fully automatic, you don't have to do anything. Having come from another AWD car where it's full time and a 50/50 split, the Cadillac's machinations and splitting of torque is quite noticeable to me. I can often feel a distinct lag between when the rear wheels are starting to lose traction and the fronts join the party, although it probably wouldn't be noticeable to anyone not familiar with a different system. The difference is in one (the 50/50 split) the car always just goes without a fuss. In the CTS, it needs to get a little bit out of shape before you have the traction you need. Same destination, different methods of getting there.

    It's been posted not this forum before (I believe from a GM engineer) that the torque split is 25/75 front/rear in normal driving but could direct as much as 100% torque to the front wheels as needed.
