The air curtains are visible just below the headlights of this 2022 GMC Sierra Denali prototype, and are set against a white camo body finish applied to a small portion of the bumper. The feature includes horizontal slats bisecting a small vertical intake mounted in the corner of the bumper.
So far, we have yet to see these front air curtains on any other refreshed 2022 GMC Sierra 1500 prototype other than the Denali trim level. Earlier this week, GM Authority brought you additional spy photos showing prototypes of the refreshed 2022 GMC Sierra 1500 Elevation and refreshed 2022 GMC Sierra 1500 SLT, neither of which had the visible front air curtains like this Denali prototype. That said, it’s possible that the camouflage on the Elevation and SLT prototypes examined previously obscured the feature from view.
At the moment, the current 2019+ GMC Sierra 1500 also has air curtains, as does the Sierra’s corporate cousin, the Chevy Silverado 1500. However, the curtains on the Sierra are not as prominent as those on the Silverado, with the latter incorporating “sideburn” styling elements that have been the subject of much controversy among fans. To this latter point, the refreshed 2022 Chevy Silverado 1500 will no longer incorporate the sideburn styling elements into the front fascia, as GM Authority covered previously.
For those who may not know, the General Motors Air Curtain technology is designed to provide improved aerodynamic performance by directing oncoming air around a vehicle’s wheels, rather than into the wheelhouses. This effectively reduces drag, and thus improves a number of factors, such as vehicle fuel economy, as well as reduced noise, vibration, and harshness (NVH) in the cabin.
In addition to a new front and rear fascia design, the refreshed 2022 GMC Sierra will feature a completely overhauled interior with a new center stack, infotainment screen, dash, and center console.
Prior to the launch of the refreshed 2022 GMC Sierra, General Motors is offering the 2022 GMC Sierra 1500 Limited, a stop-gap model intended to bridge the gap between the pre-refresh 2021 model year and fully refreshed 2022 model year.
