Snapped! 2017 Chevrolet Silverado, GMC Sierra HD Shed More Camo
Updated HD Models Inch Closer to Production, Powertrain Changes Expected
After all the activity in the 1/2-ton segment with the Ford F-150, the styling updates for the 2016 Silverado and Sierra 1500, and the Nissan Titan XD coming soon, truck brands are now turning their attention to the HD models. Ram has already announced a 900 lb-ft Cummins will be offered in the 2016 Ram 3500, and we know an all-new aluminum-bodied Ford Super Duty will be coming for the 2017 model year. General Motors is not letting any grass grow between its toes, with updates coming to the Silverado and Sierra HD, expected in showrooms in late 2015 or early 2016.
Here, we see the GM HDs with less camouflage than ever before. Interestingly, the grilles on these test models don’t seem to reflect the changes made to the 2016 1/2-ton models, but the testers could be wearing current-model sheetmetal. We’re expecting the final 2017 models to feature a revised grille and front end treatment similar to the lighter-duty models.
GM recently made a significant investment in its DMAX production facility in Ohio that builds the 6.6L V-8, in preparation for a “next-generation” Duramax. A more powerful Duramax is a given, considering it is now a distant third in the HD torque race. GM’s proven and well-liked 6.0L Vortec port-injected gas V-8 used in the current HD models may finally make way for the new fifth-generation small-block V-8, possibly with an iron block to meet the durability needs of HD customers. The HD trucks are also expected to use the 8L90 eight-speed automatic transmission, at least with the gas engine. It’s unknown whether the mandatory Allison automatic transmission with the Duramax will add two more cogs or remain a six-speed.
