This model is almost comparable the DTS, but with a totally different body and some other small changes, this full size passenger vehicle has seemed to stand up to its older counterpart and make a worthwhile second choice for consumers. The body style looks more like a full sized BMW than it looks like a Cadillac. These models come with a V-6 engine but offer about 25 more horsepower that the DTS, which brings it to 302 HP from its 3.6 liter motor.

The STS comes standard with some of the features that you would have to pay for on other Cadillac models. The stabitrak electronic stability control system, OnStar, XM Radio and keyless entry all come as part of the standard STS options. One feature that is very important to some is the all wheel drive option and this is available for a fee. All other models are rear wheel drive and this is a good choice for a vehicle of this size. If a new look and a luxurious car to seat up to 5 passengers comfortably, the STS is a viable option.

Not much. The outdated V-8 engine has been dropped for 2011 and that’s it. Otherwise, the STS carries on with the same dated styling inside and out. Though more competitive than the DTS, the STS remains in a holding pattern likes its older sibling, both waiting to be replaced by the new XTS flagship sedan.

Unlike the DTS, the STS has been updated some over the years and sits halfway between the two generations of Cadillac’s Art and Science design theme. There are no external changes for the 2011 STS.

Power leather seats are standard across the line, as are OnStar and a premium Bose stereo. Navigation and Bluetooth are optional, while automatic climate control and satellite radio are standard.

With the V-8 gone, all performance is left up to the 302-horsepower V-6 with its 315 pound-feet of torque, which as just as well, as it’s significantly more powerful than the old V-8 anyway and more fuel-efficient to boot. Both transmission and suspension are tuned for a plush ride, not sporty driving.

Driver and passenger front airbags are standard, as are front and rear curtain and side airbags. Stability and traction control are also standard on the STS, along with OnStar Automatic Crash Response.
