Styling of the DTS is "more architectural and linear," said Gary Cowger, former president of General Motors North America, during its initial appearance. The new model's styling evokes Cadillac's STS sedan.

Led by a new eggcrate grille with central wreath-and-crest badging and fresh front-end sheet metal, the DTS features vertical xenon high-intensity-discharge headlights and LED taillamps. Rear quarter panels and the deck lid are new.

Available technologies include a four-channel StabiliTrak electronic stability system with brake assist, as well as Magnetic Ride Control. Either 17- or 18-inch tires can be mounted on the car. Riding a 115.6-inch wheelbase, the DTS sedan is 207.6 inches long overall and 74.8 inches wide.
