GMC is elevating the 2018 Yukon Denali lineup with styling and trim enhancements, as well as a new, advanced 10-speed automatic transmission. A new, sculpted grille design distinguishes the Yukon Denali, while new Mastique Ash real wood trim adds depth and richness to the interior.

The new 10-speed transmission — paired with Yukon Denali’s 6.2L V-8 engine — enhances refinement with world-class shift smoothness, responsiveness and quietness.  

Multi-Dimensional Grille Design

GMC designers evolved the iconic Denali grille with a multidimensional, sculpted interpretation that, like other contemporary GMC elements, was designed in a layered manner. It’s a theme seen in other new GMC models such as the Acadia and Terrain.

In addition to a more sophisticated appearance, the new grille offers greater airflow to the radiator. Active aero shutters behind the grille close in certain conditions on the highway to reduce aerodynamic drag and enhance efficiency.

10 Speeds, Refined Performance

The Yukon Denali’s new 10-speed automatic leverages the engineering experience of General Motors’ multispeed transmissions to deliver improved performance.

A wider, 7.39 overall gear ratio spread, compared to the Yukon Denali’s previous eight-speed automatic, enables a lower numerical top gear ratio and contributes to greater efficiency.

The transmission’s optimized gearing and proprietary controls allow the 6.2L V-8 engine to deliver a winning combination smooth operation and precise response.

Standard and available features include:

  • 420-hp 6.2L V-8 engine with direct injection and Active Fuel Management
