    I believe the dealer told me that the AWD is 50/50 and "competitive" mode is 80% rw 20 fw

    The AWD IS 25/75 front rear in everyday driving. Completion mode turns off traction control and stabilitrak and firms up the steering.

    As gohawk said it's actually 25/75 under normal usage. The only way to disable RWD is to pull the AWD fuse, which was confirmed in another thread. What was never confirmed was whether this was safely reversible.

    Re: Awd really necessary?

    Hi I had a 2005 3.6L lux sport RWD and now own a 2011 3.6 Premium AWD. I have All Season tires on both. If you live in an area with a lot of snow I suggest if you get a RWD then I suggest you get snow tires. I had difficulty in the snow as the RWD car tends to fishtail going up the slightest incline. In most instances the car was great but I got stuck a few times away from home and therefore opt'd for the AWD when I replaced the car last year. Plus I didn't want the hassle of storing 4 snow tires. I can say the AWD drive definately adds a 2 MPG mileage penalty. Also the AWD is not as quick. I used to average 18 mpg in my daily commute and I now average around 16 mpg. The AWD car has a much heavier feel but I find I actually prefer its ride. It is very secure and serene - an amazing car with a beautiful ride. From this board I learned to use the Sport mode when passing and merging to compensate for its weight disadvantage. Bottom line it depends what you are looking for in a car. If you have a place to store the snow tires and don't mind changing the tires out, I would go with the RWD but either way you will be happy as they are both great cars.

    The only way I know to purposely and safely disable AWD on a CTS4 and run RWD only is to pull the "All-Wheel Drive" fuse at the underhood fuse block. I recently pulled the fuse on my '11 CTS4 and drove the car that way for about 60 miles, on the highway. No problems whatsoever. In disabled AWD mode /enabled 100% RWD mode I evidently gained roughly 1.5 to 2 MPG (per the DIC) as regards highway fuel economy, driving at 70 mph.
    As info.. with the AWD fuse pulled a message appears on the DIC each time the engine is started advising the AWD system needs to be serviced. The message is dismissed with a button push. Re-installing the fuse (with the engine/ignition off, of course) restores AWD to its normal state/functionality.

    As Mrmiker56 mentioned in his post above - the AWD car does have a heavier feel, but I too prefer its ride and feel compared to the RWD car (which I owned for over 2 years - a fully optioned 3.6L DI '09 CTS). When I took delivery of my '11 CTS4 Premium Sedan I was amazed at how good the ride is, particularly given the fact the car came with the optional 19" wheels/tires (FE5 19" all-season tire package) versus the 18" wheels/tires installed on my previous '09 CTS.

    Colorado. AWD is the only way to buy a car. We have a Golf and its fine for commuting 90% of time. However for skiing on powder days or taking trips 6 months of the year you can't count on it. Already have torn the engine shield off the caddy in deep snow. Golf was stuck dead. Even my Dodge 1500 4wd was worthless a few of our snow days. You need a decent 4 wd or an AWD car here if you care to get from point a to b on time.

    I have AWD, in TX (insert jokes here), I opted for it for handling. On a trip over Christmas, it got nasty in Little Rock on my way to Memphis; you should have seen all the cars, trucks (even 4-wheel drive) and big rigs stuck or run off the road. Kate zipped right passed all if them! I figure it's because of the superior AWD technology and much lower center if gravity. I was very impressed, far exceeded my expectations.

    I always wondered if there was a safe way to disable the AWD system. I would not mind disabling it during the summer months. Do you think it would have no detrimental effects?

    RandyG, I was assured it would have no detrimental effects. A GM powertrain engineer involved with the development and qualification of the AWD system for the 2nd gen CTS (he posted several times in this Cadillac forum a few years back) advised me via email recently that pulling the fuse safely disables AWD, and the vehicle can be run that way indefinitely with no detrimental effect. On some competitor AWD vehicles there is a switch in the cabin to disable AWD (to convert to 2WD), and that switch essentially has the same result as what pulling the "All-Wheel Drive" fuse does in a gen 2 CTS4. Asked why GM didn't provide such a switch in the 2nd gen CTS4, the response was that Cadillac, for mostly marketing reasons, preferred to offer a "full-time" all-wheel drive system on the 2008+ CTS, where the customer would never have to deal with a switch and would be afforded "AWD peace of mind" all year round.

    Thanks RAB. I will give it a shot and see how I like it. Best regards.

    Excellent! Always wondered why there wasn't an on/off switch/button much like suvs/trucks with 4wd; especially, nowadays with so much mpg concerns.

    Re: Awd really necessary?

    Just spent the last four winters driving a Pontiac G8GT, shipped with summer only tires and ended up running two sets. Factory from April to November and then Blizzacks in the winter with sand bags in the trunk. Got around well but even with the Blizzacks not a reasuring drive in any snow over 4". Just traded for a CTS4 with the 3.6 DI. Main reason for the trade was the AWD. Gaev up almost 75hp but all the extra pluses were just the topping on the cake.
