2016 GMC Sierra 2500: What's New, Specs & Features
Last updated August 13, 2026
The most important change for the 2016 GMC Sierra 2500 HD is that HID projector headlights with GMC signature LED lighting are standard on every trim. This is not a redesign, but it is a meaningful equipment update.
About the 2016 GMC Sierra 2500
3rd generation Sierra HD (2015-2019), second model year after the 2015 redesign.
GMC positions the Sierra 2500 HD as a heavy-duty pickup that pairs serious towing and hauling ability with a more upscale feel than its Chevrolet counterpart. The core idea is "Professional Grade" capability: strong gas and diesel powertrain choices, trailer-focused hardware, and a quiet, more comfortable cabin than many work trucks. For most buyers, it is the choice for towing large trailers, carrying heavy loads, and still having a truck that feels polished enough for everyday use.
The 2016 Sierra 2500 HD ranges from a straightforward base work truck to the more personal SLE and comfort-focused SLT. SLE has an 8-inch touchscreen with Apple CarPlay and Android Auto, while SLT adds leather seating and heated front seats. Denali is the luxury version, with ventilated leather front seats, navigation, Bose audio, and an 8-inch driver display.
What changed, by category
Powertrain
The 6.0-liter gas V8 and 6.6-liter Duramax diesel carry over. A natural-gas powertrain joins the Denali, and a factory gooseneck/fifth-wheel prep package is added for towing-focused trucks.
Styling
HID projector headlights with GMC signature LED lighting become standard on every trim. Alloy wheels shift from standard to optional on SLT and Denali.
Safety
Digital Steering Assist joins the equipment list for SLE Double Cab and Crew Cab models, SLT, and Denali.
Tech
Touchscreen systems on equipped trucks get faster processing plus Apple CarPlay and Android Auto compatibility. Wireless charging and a remote-locking tailgate join the option list.
