2017 GMC Sierra 3500 Release Date

Several recently taken spy photographs revealed that GM is currently working on upgrading the heavy-duty lineup for the 2017 model year. As part of the process, both the Chevy Silverado and GMC Sierra HD are due to receive a number of styling revisions as well as certain mechanical updates. Some sources claim that we might even get to see a brand new Duramax diesel engine powering GM’s mechanically identical twins. Of course, the main purpose of such a move will be to challenge Ram’s stunning 900 pound-feet of torque provided by the Cummins turbodiesel. It remains to be seen whether the 2017 GMC Sierra 3500 will be able to boost the torque numbers currently rated at 765 lb-ft.

Engine Range

As already mentioned, the 2017 GMC Sierra 3500 could introduce an all-new turbodiesel unit to its engine range. As for the current version, its standard engine comes as the 6.0-liter V8 that makes 360 horsepower and 380 lb-ft of torque. Its power is transmitted to the wheels through a six-speed automatic gearbox. However, reliable sources suggest that the 2017 updates should include a new 8L90 eight-speed automatic transmission, at least when it comes to the gasoline-powered V8. Now, the optional turbocharged 6.6-liter diesel V8 will churn out 397 hp and 765 lb-ft of twist, coupled with a six-speed automatic. While rear-wheel drive is offered as standard, four-wheel drive comes optional. A properly equipped Sierra 3500 is able to haul up to 7,374 pounds of payload. While maximum conventional trail capacity is rated at 20,000 pounds, the fifth-wheel towing capacity can hit 23,200 pounds.

2017 GMC Sierra 3500 Design Changes

When it comes to the exterior styling, the 2017 GMC Sierra 3500 is expected to bring a modified front end and several minor visual changes. Despite the camouflage, the spied prototypes reveal a redesigned front bumper and grille. Other notable changes include new headlights, while the refreshed HD trucks are due to receive LED daytime running lights for the first time. These cosmetic changes should keep GM’s trucks fresh until the whole new generation makes its debut in 2020. The rest of the exterior and interior design is expected to carry over from the 2016 model.

We’re still awaiting official confirmation of the release date for the 2017 GMC Sierra 3500 but we expect it to hit the market in late 2016.
