GMC Yukon Denali 2018

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 GMC Yukon Denali, while new Mastique Ash real wood trim adds depth and richness to the interior.

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

"Yukon Denali has always matched style with substance, and the enhancements for 2018 advance that legacy," said Duncan Aldred, vice president of Global GMC. "The foundational elements of exclusive design, premium touches and uncompromising capability have made Yukon Denali an icon for nearly 20 years."

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.

"The new grille, which is flanked by HID headlamps and LED Signature Lighting, advances the design legacy established with the very first Yukon Denali in 1999," said Matt Noone, director, Global GMC Exterior Design. "It's a more exciting and sophisticated design, while remaining instantly recognizable as part of the GMC Denali family."

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 GMC 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 GMC 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.
