2021 GMC Sierra 1500 Denali Specs

2021 GMC Sierra 1500 Review

Check the price in your area:

The Denali comes with a full house of luxury features, including onboard navigation, an eight-inch digital instrument cluster, wireless device charging, a power-sliding rear window, and a seven-speaker Bose sound system. On the safety side, GMC adds lane change alert and blind-spot monitoring, front and rear park assist, and rear cross traffic alert. But the biggest change is the suspension, which is a magnetorheological adaptive suspension setup that makes the Denali more comfortable despite riding on larger 20-inch alloy wheels than lesser trims.
