There was a time when pick-up trucks were just pick-up trucks, with no convenience features and a rudimentary interior design.

The GMC Sierra Denali is just an example of how things evolved along the time, being one of the most luxurious pick-up trucks on the market.

For 2019, the Denali featured lots of innovative features to provide maximum practicality and comfort.

The luxurious pick-up truck featured the most innovative tailgate in the automotive industry. The lower part of it came down and served as a step, the little step could also be used as a cargo stopped if folded up and the top half could be lowered and added to the step, turning into an increased cargo stopper. And this was no hard thing to do, the tailgate featuring 2 buttons for easy actioning.

At the front, the Denali was just massive, with a huge chrome grille and fog lights the size of a smaller car’s headlamp.

Inside, the Denali offered multiple storage spaces and even two separate gloveboxes. The interior mirror was highly functional, offering a much wider view of what was behind using the rear view camera instead the obstructed real image, and a car the size of a Denali was much easier to manoeuver.

All the controls were intuitively placed and easy to use, drivers could choose the preferred driving mode by switching between Tour, Sport, Off Road and Tow/Haul. Other features included heated seats, heated backrests, cooled seats, 2 USB ports and a regular household and even a huge head-up display. While in the off-road setting, the system displayed even the vehicle’s angle, offering a proper experience and enhanced safety.

Besides the usual information about the vehicle’s state, with the Denali, the drivers could also see the air filter life and the brake pads life in percentage.
