5 Fast Facts About the 2013 GMC Sierra 2500HD

By Jeff Youngs, February 23, 2013
The GMC Sierra 2500HD has HD in its name, signifying Heavy Duty, but this is a medium-duty pickup truck that can carry more payload and tow more weight than a Sierra 1500. GMC has already introduced a redesigned 2014 GMC Sierra 1500, and it is widely rumored that new versions of the Sierra 2500HD and Sierra 3500HD models will also arrive soon. In the meantime, GMC dealers are offering appealing discounts on the aging Sierra HD lineup, and if you need a new truck sooner rather than later, here are 5 fast facts about the 2013 Sierra 2500HD that you may want to know before making a purchase.

1.) GMC sells the Sierra 2500HD in regular cab, extended cab, and crew cab styles with a standard or long cargo box and with 2-wheel or 4-wheel drive. Work Truck (WT) and SLE trim levels are offered for all three cab styles, with SLT trim available for extended cab and crew cab trucks. The Sierra 2500HD Crew Cab can also be equipped with a luxurious Denali trim level.

2.) The 2013 GMC Sierra 2500HD is equipped with a standard E85-compatible, 6.0-liter V-8 engine generating 360 horsepower at 5,400 rpm and 380 lb.-ft. of torque at 4,200 rpm. For 2013, this engine is can be specified to operate on Compressed Natural Gas (CNG). A heavy-duty 6-speed automatic transmission transfers power to the rear or all four wheels, and includes a Tow/Haul Mode to help with towing and hauling.

3.) As an option, the Sierra 2500HD is equipped with a B20 biodiesel-compatible 6.6-liter turbo-diesel V-8 generating 397 horsepower at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm. A heavy-duty Allison 1000 6-speed automatic transmission is standard with the turbo-diesel engine, and it includes a Tow/Haul Mode as well as engine exhaust braking to better control vehicle speed on hills and to reduce brake wear. The turbo-diesel V-8 requires Diesel Exhaust Fluid (DEF) for its selective catalytic reduction after-treatment system, and it must be re-filled every 5,000 miles. GMC says  that the turbo-diesel engine's glow plug cycle takes no longer than three seconds at temperatures of 20 degrees below zero, and that a high-idle mode switch helps to quickly warm the truck's cab on cold days.

4.) The 2013 GMC Sierra 2500HD is equipped with standard Trailer Sway Control and Hill Start Assist, the latter feature holding the truck still on a hill for up to 1.5 seconds while the driver switches from the brake pedal to the accelerator pedal. An integrated trailer brake controller is optional on the WT and SLE, and standard for the SLT and Denali models. Maximum payload capacity, depending on the version selected, is 4,212 lbs., and the Sierra 2500HD can tow up to 13,000 lbs. of trailer with a conventional hitch. Outfit it to handle a fifth-wheel trailer, and maximum towing capacity rises to 17,800 lbs., when properly equipped.

5.) Luxury truck buyers may want to consider the 2013 GMC Sierra 2500HD Denali, which offers a number of standard upgrades over other models. They include 12-way power front seats wrapped in premium perforated leather, heated and ventilated front seats, a heated steering wheel, brushed metallic and woodgrain cabin trim, and a premium surround-sound audio system. On the outside, the Sierra 2500HD Denali is equipped with additional chrome trim, heated power retractable side mirrors, side steps, and chrome wheels.
