Chassis tuning has focused on achieving a smooth, quiet, refined ride. The DTS features an all-new front cradle design, with the engine mounted to the cradle, and the cradle mounted to the body rails.

A number of integrated chassis control technologies include four-channel anti-lock brakes and traction control, four-channel StabiliTrak with Brake Assist, and Magnetic Ride Control. The DTS also employs larger 17- or 18-inch wheels and tires, as well as larger 323-mm brakes for enhanced stopping power.
