Sierra Denali Ultimate

The GMC Sierra Denali Ultimate is offered exclusively on four-wheel drive 1500 crew cab models with either a 5’ 8” or 6’ 6” cargo bed. It is distinguished with 22-inch wheels with chrome or black insert), a standard sunroof, chrome tow hooks and standard technologies, including Tri-Mode Power Steps – that move rearward to serve as a step into the forward section of the cargo bed. Lane Keep Assist and IntelliBeam automatic headlamp control are also standard.

Sierra’s 6.2L V-8/eight-speed automatic powertrain combination offers the light-duty segment’s highest output: 420 horsepower (313 kW) and 460 lb-ft of torque (623 Nm). Active noise cancelation technology contributes to a quieter driving experience and is featured with the 6.2L engine. A 5.3L V-8 with the new Hydra-Matic 8L90 eight-speed automatic transmission is the standard powertrain.

An integrated trailer brake controller is standard on the Sierra Denali Ultimate and allows the driver to adjust the amount of output available to the electric trailer brake and to manually apply the brakes.

Additionally, Sierra Denali’s standard, segment-exclusive magnetic ride control delivers more precise body motion control, for a greater feeling of responsiveness to the driver and a smoother ride for passengers. Its sensors “read” the road every millisecond, triggering damping changes in as little as five milliseconds in electronically controlled shock absorbers that replace conventional mechanical-valve shocks.
