We get another glimpse at the next generation of GM heavy duty trucks. These should be designated as the 2017 Chevy Silverado HD and 2017 GMC Sierra HD, although there is no official word on this yet. We first saw similar prototypes testing in July of 2014. These test mules now have black tape on the grilles, but the hood covers with a peculiar center cutout are still there.


Judging by the big DEF tanks under the passenger side, these trucks are testing the latest version of the Duramax turbo-diesels. Can the next V8 Duramax challenge the Ram and Ford with close to 900 lb-ft of torque? If it does, then it’s understandable that it may need an extra cooling duct in the hood. Who knows, perhaps there is nothing there or it is simply a new style item.

These prototypes are towing all kinds of trailers: flat-bed, utility box, and gooseneck trailers. They are also 3500 Dually prototypes in this bunch.

We will work to get more details on this, in the meantime – please take a look at the next generation prototypes of the Ford Super Duty. These should also be designated as 2017 model year pickup trucks.
