It's so nice

Vehicle: 2006 Cadillac DTS Luxury II 4dr Sedan (4.6L 8cyl 4A)

I bought my 06 DTS as a program car with 17K on it. I've had it for over 3 years and I absolutely love it. My gas mileage on the highway nears 30 MPG. It's very comfortable and drives like a dream. The cooled seats are a blessing in the New Mexico summers. This is my 4th Caddy and I'll buy more.

Not your grandfather's boat

Vehicle: 2006 Cadillac DTS Luxury II 4dr Sedan (4.6L 8cyl 4A)

Just traded my 04 Deville - which I loved but wanted to upgrade. The 06 DTS is chock full of features and is tuned much differently than the previous model. Feels more Euro and has a throatier exhaust and more road feel. Seats are way more supportive. Solid as a rock though and is still a wonderful example of what makes big American cars different from the rest

Great car

Vehicle: 2006 Cadillac DTS Luxury II 4dr Sedan (4.6L 8cyl 4A)

Purchased this vehicle after having a 20002 Cadillac with only 60,000. Really liked the styling. A problem that I continue to have is the tire monitoring system. Had 2 sensors replaced and am having problems again. Just cannot keep the sensors operating properly. Only other problem was the electrical system went dead one day. Overall, a lovely car to drive. I get very good gas mileage (27-29) on long trips. In town, normally 20-21. Love the car.

I am embarrassed I like this car do much. Looks great, mileage is surprising, the cooled seats are off the chart. My friends all make fun of me for driving the "old man's car" until they rise in it. I now get stuck driving lots of places. The Cadillac dealership however could learn from the high end imports.

Would not start

Would not start AGAIN. This is the 3rd time since we bought it. It goes back to the dealer and on the 1st time he said we left something on. According to the owner's manual everything is supposed to shut down after 10 minutes. 2nd time they could find nothing. They still have it for the 3rd. time today. It remains to be seen what the problem may or may not be. Also lots of luck calling 1 800 Cadillac to get it started. The first 2 times they sent a qualified starting service, not today. This guy was not equipped to start a car that was still in the garage.

I'd buy it again

This is my 4th Caddy and it has more omph that any of the previous 3. Great color -Ice Blue. Got better mileage with the '03 but this still gets 25-27 mpg on the road. Love the extra toys - heated steering wheel, OnStar, etc.


Full 2006 Cadillac DTS Review

What's New for 2006

The DeVille receives a significant batch of updates for 2006, and Cadillac has renamed it the "DTS." Highlights include new front and rear sheet metal and fascias, a new interior, improved chassis components and a strengthened structure.


For more than 50 years, the DeVille has been one of the most popular models sold by Cadillac. Last redesigned in 2000, the DeVille benefits from a major refresh and name change for 2006. The outgoing DeVille has accounted for nearly half of all Cadillac's sales for the past two decades, so its successor, the DTS, has a set of big tire tracks to fill.

With its egg-crate grille, vertical bi-xenon headlamps and sharply creased sheet metal, the DTS embodies all of Cadillac's 21st-century styling cues. A lower dash and a new analog clock combine with low-gloss interior surfaces to update the cabin. Taller folks will appreciate the additional inch of seat travel, and dual-density seat padding promises comfort and proper support. Safety is improved via an industry-first dual-depth front-passenger airbag that varies its inflated volume based on the severity of the crash and the occupant's seating position. Mounting the DTS' engine is a separate cradle that should reduce the already low levels of noise, vibration and harshness reaching the cabin.

By most accounts, the Cadillac DTS is a sophisticated American luxury car that remains true to Cadillac's heritage. Between its powerful engine, cavernous interior and multitude of high-tech vehicle systems, the DTS offers a little bit of everything. There's more than enough room for four adults and the trunk can swallow a weekend's worth of baggage with room to spare. Compared to other cars in its price range, the interior could use some higher-quality materials, but overall it's a clean design with simple controls. If you like your luxury cars big, comfortable and quintessentially American, the 2006 Cadillac DTS will serve well.

Body Styles, Trim Levels, and Options

The Cadillac DTS is available in one model for 2006. Standard amenities include tri-zone automatic climate control, leather upholstery, OnStar, bi-xenon headlamps, power front seats and one-touch windows. In terms of luxury options, you find adaptive cruise control, heated and cooled front seats, seat memory for the driver, a heated rear bench, a power rear sunshade, rain-sensing wipers and a Bose sound system. Also available on this Cadillac car is a Magnetic Ride Control suspension that monitors and adjusts individual shock damping according to road surface changes for maximum comfort and performance.

Powertrains and Performance

Even with its relatively slim and trim shape, the Cadillac DTS is still a sizable sedan, so the 4.6-liter V8 engine is a welcome sight under the hood. The standard engine is a 275-horsepower version, while an upgraded version boasting 291 hp is optional. A four-speed automatic is the only transmission choice.


On hand to maintain optimum vehicle control is StabiliTrak, GM's advanced stability and traction control system. A vast array of onboard sensors can detect if the vehicle is deviating from the driver's intended path and selectively apply individual brakes to restore control. All Cadillac DTS models include standard front side-impact airbags, as well as front and rear side curtain airbags. Should you need assistance in an emergency (or just need tickets to the basketball game), GM's OnStar communications system comes standard. Parking sensors are also available.

Interior Design and Special Features

Interior room in the DTS is outstanding, with both five- and six-passenger models available. Front-seat passengers are coddled in sumptuous leather seats. Rear passengers are given just as much legroom as front passengers, and the trunk can hold several suitcases without a problem. The overall interior design and materials aren't up to the standards of the European or Japanese competition, but the majority of the controls are easy to decipher, and build quality is generally good.

Driving Impressions

Despite its considerable size and softly tuned suspension, the 2006 Cadillac DTS carries itself well. There's plenty of power on hand for quick passes, while the suspension manages to offer a compliant ride and solid handling. Road and wind noise is barely noticeable and the sheer volume of room in the cabin makes it a terrific highway cruiser.
