GMC Teases 2017 Sierra Denali HD With Functional Hood Scoop

See anything different about the 2017 Sierra Denali 2500HD that GMC teased today? Of course you do – it’s that chrome trimmed hood scoop placed right above the truck’s huge chrome grille.

Thing is, GMC won’t tell us what’s under that new hood design, at least not yet. It does say the air scoop is functional and that it hints “at what is beneath its bold new appearance”, while the ‘Duramax’ chrome badge placed on the side crease of the hood confirms that there’s a diesel unit powering the full-size heavy duty truck.

The current 2016 Sierra 2500HD comes with a 6.6-liter turbocharged V8 diesel delivering 397hp and 765 lb-ft of torque paired to an Allison 1000 automatic transmission. Will the additional cold air input together with any other changes to the diesel lump result in more power, better efficiency or both? We’ll just have to wait and see.

One thing that’s for sure is that the same upgrades will be applied to the GMC truck’s 2017 Chevrolet Silverado HD sibling, with both models expected to be revealed in the coming weeks/months.

    Functional. Are you paying attention Tacoma?

    Hilarious that they trimmed the scoop with chrome. Not a good look.

  • Antenna

    For years GM can’t get rid of that stupid antenna over the driver’s head. Odd looking, out of proportion, never color matched to vehicle’s color – American style all in all. Koreans done better by now.

    • Swagger

      All USDM pickup manufacturers use some version of this antenna and they are available “color matched” on higher trim levels. Koreans don’t even sell pickups in the US, so your comment that they have “done better by now” is unsupported.

      They do that to take advantage of the driver’s enormous ego which attracts all the radio stations.
