From the looks of it, some versions of the forthcoming 2020 Chevrolet Silverado HD are set to feature a “flow-through” lettered front grille, where the typical, classic Chevrolet bowtie emblem is replaced with lettering that reads “CHEVROLET” in outline, allowing airflow straight through the letters. This isn’t too principally different from Chevrolet’s “flowtie” grille, which replaces the classic bowtie emblem with a hollow-center one to allow air to pass through.
That piece was introduced for the 2014 Chevrolet Camaro Z/28, and the simple change allowed for an extra 3 cubic meters of airflow per minute, helping reduce engine coolant and oil temperatures by about 2°F during long sessions on the race track.
But maintaining adequate cooling airflow isn’t just critical in track cars; it’s also a must-have in hard-working towing and hauling vehicles like the 2020 Silverado HD. The all-new, heavy-duty Silverado will be the third Chevrolet truck to rock a flow-through lettered grille, after the 2019 Chevrolet Silverado 1500 (on Work Truck, Custom, and Custom Trail Boss models) and the 2019 Chevrolet Colorado ZR2 Bison. Since the 2020 Silverado HD features a thick, horizontal bar across the full width of the grille, and that bar is where the emblem is located, using the “CHEVROLET” lettering instead of the typical bowtie logo allows for more of the bar’s total surface area to be hollowed out.
As on the Chevrolet Colorado and the Silverado 1500, the 2020 Silverado HD’s flow-through lettered grille will likely only be available with certain trims – logically, probably those whose intended use cases demand greater cooling airflow through the radiator. As Chevrolet’s April teaser image (top) suggests, the grille design will at least be available on some Silverado HDs equipped with the Z71 off-road package. That simple design change ought to allow the truck to go harder, for longer, on each customer’s favorite set of trails.
The all-new, 2020 Silverado HD is expected to bow at the 2019 North American International Auto Show in Detroit, before going on sale in the third quarter of 2019. For more Chevrolet Silverado HD news, keep it tuned to GMAuthority.com.
