The Denali trim represents the highest level of luxury for the GMC lineup and the highest priced at $50,135 for a rear-wheel-drive model. The Yukon Denali has more in common with the Cadillac Escalade than it does with the Yukon SLT, which starts at $43,145.
Compared to the SLT, an additional $6,990 gets you the Denali’s exclusive powertrain with more power – 403 horsepower versus 320 hp. Consequently, the mileage is worse on the Denali: 12/19 mpg city/highway versus 14/20 mpg on the SLT.
The Denali is equipped with a more sophisticated suspension – variable shock dampening and rear air-assisted shocks – that helps maintain a consistent ride quality despite load variance; this is optional on the SLT. The Denali also has more sound-deadening material aimed at giving the SUV a quieter ride.
Besides the mechanical differences the Denali has aesthetic upgrades, including a Denali-specific honeycomb grille and lower insert, 20-inch chrome wheels and other exterior chrome accents. On the inside, the Denali has a heated, leather-wrapped steering wheel with unique “Denali” badging, front and rear heated leather seats and an exclusive 10-speaker Bose audio system.
Denali trims are also found on the midsize GMC Envoy SUV and the full-size GMC Sierra pickup.
