The most recent spy shots of the upcoming 2020 Tahoe published earlier this week confirm the presence of a new aerodynamics feature – front air curtains.
Looking at the large SUV from the rear reveals a vertically-shaped cutout (“tunnel”) that diverts air coming into the front fascia in a predetermined manner, thereby contributing to better aerodynamic performance.
About Aerodynamic Air Curtains
Air curtains maximize a vehicle’s aerodynamic performance by utilizing specially-engineered tunnels at the front of the vehicle. The tunnels manage airflow in a specific and pre-determined manner, guiding air around the vehicle’s wheels, rather than allowing it to run uncontrollably into the wheel houses. The result is maximized aero efficiency and reduced aerodynamic drag.
Better aerodynamic performance, in turn, translates to improved fuel economy – particularly on the highway – as well as reduced noise, vibration, and harshness (NVH) levels experienced by the driver and passengers.
Air curtains have been making their way across the Chevrolet model range over the last several years. As of this writing, the technology is exclusive to Chevrolet vehicles within the GM family.
The first application of air curtain technology by Chevrolet (as well as by GM) was the sixth-generation Chevrolet Camaro, which was introduced for the 2016 model year. The second Chevy model to use the feature was the all-new 2019 Silverado, which shares the T1 platform with the 2020 Tahoe and its longer twin, the 2020 Suburban. Notably, the air curtains are not featured on the Silverado’s platform mate – the 2019 GMC Sierra.
Given the technical and proportional similarities of the Tahoe and Silverado (as well as the Suburban), it’s safe to assume that the execution of the air curtains on the 2020 Tahoe will be very similar, if not identical, to that of the 2019 Silverado.
We should see much more of the vehicle in the months ahead as it nears development completion and is introduced sometime in the first half of the 2019 calendar year. Stay tuned!
