There are plenty of prototype Chevrolet Silverado 2500/3500 heavy duty pickups doing durability testing in and around General Motors Milford Proving Grounds outside Detroit. From what our spy shooters tell us — which we suspected — much of the design language from the 2014 Silverado will migrate into the HD trucks; however, the photos here indicate there may be something unique about the grille and front-end look. Here's what our spies tell us.
"It appears that the Silverado HD will gain the impression of greater brawn by ditching the 1500's split center bar in favor of a thicker, solid chrome bar. The result is greater visual weight and a beefier countenance. Slim horizontal slats (two above and three below) sandwich the thick horizontal grille bar, adding some further substance to the Silverado HD's grille treatment."
