2016-gmclife-sierra-hd-reveal-mh-980x347

If you are in the market for a new heavy duty truck, stop by SouthTowne Motors to test drive the new 2017 GMC Sierra HD. This vehicle features a powerful 6.6-liter V-8 turbo Duramax diesel engine that makes 397 horsepower and 765 pound-feet of torque. You’ll have plenty of towing power with this truck. An Allison 1000 Series transmission with overdrive backs up the engine. You’ll get 680 highway miles on a single fill-up.

Excellent Fuel Economy

The GMC Sierra gets its excellent gas mileage thanks to the transmission, which is designed to handle all of the torque the engine puts out; and helps with an exhaust braking system. Additionally, the direct injection technology provides fast starts in cold weather, maximum efficiency, low emissions and lots of power.

Brakes, Suspension and Driver Control

You’ll need some excellent rotors to help stop the GMC HD because of the power this truck puts out. The rotors use ferritic nitrocarburizing technology, exclusively patented by GM. This technology strengthens and hardens the brakes. And the Duralife protects the rotors against corrosion, thus doubling the life of the rotors.

And, the Sierra uses a coil-over-shock front suspension, and, in the rear, 3-inch wide multistage rear leaf springs. The leaf springs help handle heavier loads in the bed or increased tongue weight on the hitch.

Additional features include available hill descent control, standard StabiliTrak for braking and throttle management, an automatic locking rear differential, driver shift control and digital steering assist.

Interior Features

The 2017 GMC Sierra HD features a quiet cabin with triple door seals to block outside noise, hydraulic body and engine mounts to reduce vibration and aerodynamic mirrors that reduce wind noise. The interior also features leather-appointed seats, a leather-wrapped steering wheel, aluminum trim accents on the center console, steering wheel and instrument panel and soft-touch instrument panel and door trim.

Additional features include dual-density foam seats, a huge center console that holds laptops and hanging file folders, 12-volt charging outlets, USB ports, locking storage under the seat on the SLE and SLT models, an 8-inch diagonal color touch radio, IntelliLink, Bluetooth, smart phone integration and HD radio.
