2018 GMC Sierra Denali is a class “K4” pickup with rear- or all-wheel drive. The restyled version of the third generation of the model debuted in the summer of 2015.

The changes in the appearance of the Sierra are minimal, but quite significant, as they greatly influence the perception of the vehicle. GMC designers updated the pickup’s headlights, generously adding LEDs, redesigned the radiator grille, bumpers, and rear lights.

In the interior of the Sierra, although no major changes are observed, there is still plenty of soft plastic and leather. And of course, there is a lot of equipment – the MyLink multimedia system with an 8-inch touchscreen, which after the restyling received support for Android Auto and Apple CarPlay, a forward collision prevention system, a lane departure warning system, a rearview camera, and even a driver fatigue recognition system, which alerts the driver of the need to rest not with a sound signal, but with seat vibration.
