Professional Grade engineering means crafting better solutions and making them a reality through technology. The Sierra Denali is the very embodiment of that philosophy—from its engine control and response systems to the confidence of advanced trailering technology.


Sierra Denali lets you trailer and stop confidently with braking technology:

  • Automatic Grade Braking senses when you want to slow your vehicle, and engages a Grade Braking shift schedule that helps you maintain your desired speed
  • Intelligent Brake Assist senses when you are making an emergency stop and then automatically applies full braking force before your foot can press the pedal all the way


Sierra Denali puts trailer safety and control at your fingertips:

  • The available integrated trailer brake controller is located close to the steering wheel for easy adjustments and displays the level of brake force or “gain” in the Driver Information Center
  • Standard Trailer Sway Control technology keeps the vehicle trailer heading in the proper direction, automatically using sensors to detect the rocking of a swaying trailer, and then applying the brakes to bring it back in line



Sierra Denali puts the latest engine and vehicle technologies at your command:

  • Driver Shift Control: Move through the gears like a manual transmission with the convenience of an automatic
  • Hill Start Assist: Senses potential “roll back” situations and holds full brake pressure when you lift your foot from the pedal. It gives you up to 1.5 extra seconds to apply power and drive off.



Sierra Denali works to a higher standard, powered by a 6.2L V8 engine which delivers 403 HP, and is also FlexFuel capable. Add to that the innovations and capability that embody GMC’s Never Say Never approach and you’ve got a powerful combination.

Sierra Denali is available with electronic All Wheel Drive that helps detect wheel slippage and, in a fraction of a second, responds by sending power to both the front and rear wheels to help enhance traction. What’s more, Sierra Denali’s front suspension is coil-over-shock – as opposed to torsion-bar suspension designs – delivering improved ride quality and handling.


No other competitor in its class offers a standard fully automatic locking rear differential for on or off-road use:

  • Delivers added traction in driving and wheel-slip situations
  • Senses a difference in speed between left and right rear wheels
  • Locks to turn both wheels in unison


For strong, steady power to bold acceleration on the highway, the 6.2L V8 with Variable Valve Timing (VVT) is up to any task by:

  • Monitoring, opening and closing valves for near peak levels of torque across the entire range of engine speeds



Sierra Denali proudly received a 5-star overall side crash safety rating from NHTSA5. When it comes to safety, we set our standards high to give you peace of mind – whether travelling with family or on the job site.


The StabiliTrak stability control system helps you stay on the path you are steering in bad weather or on uneven road surfaces. The system senses when your vehicle is not responding to your steering inputs and then adjusts engine speed and braking pressure to any individual wheel to help maintain directional control.


Engineered into every Sierra Denali is additional strength and protection:

  • Hydroformed-steel-reinforced safety cage design
  • Tire Pressure Monitoring System6
  • Dual-stage frontal air bags,7 driver and right front passenger seat-mounted side-impact air bags and outboard front and rear occupant head-curtain side air bags8


Sierra Denali has a standard 6-month trial subscription to the OnStar®9 Directions & Connections Plan. The plan includes:

  • Automatic Crash Response
  • Turn-By-Turn Navigation
  • Roadside Assistance
  • Emergency Services Link
  • Remote Door Unlock


Traction control measures and compares the speed of your wheels. If it senses one or more wheels starting to spin, the system applies individual brakes and manages power to slow the wheel down to maintain traction.
