2019 GMC Sierra Denali 1500

The 2019 GMC Sierra Denali 1500 is an all-new model, marking the first model year for the fourth-generation pickup truck.

Changes and updates include a switch from GM’s K2 platform to the more modern T1 platform, as well as the addition of the 3.0-liter Duramax LM2 I6 Diesel engine option and much more.

Changes from the third-generation model include:

  • Up to 360 pounds (163k) lighter than the previous model
    • GMC achieves this using a “mixed materials approach” — including aluminum for the doors, hood and tailgate, with steel for the fenders, roof and standard cargo box
  • Fully boxed steel frame is 88 pounds (40 kg) lighter than its predecessor and offers 10 percent greater torsional rigidity
  • Enhanced front and rear suspension systems with new, lightweight components
  • Denali-exclusive Adaptive Ride control with real-time monitoring of road and driver inputs
    • Reacts in milliseconds to adjust damping for optimum body control and ride isolation
