2020 GMC Sierra 2500HD Reviews

2020 Sierra 2500HD New Car Test Drive

The following review is for a 2019 Model Year. There may be minor changes to current model you are looking at.

Introduction

The 2019 GMC Sierra 2500 HD is the brand's full-size, heavy-duty pickup truck. It's reached the end of its latest generation, and soon will be replaced by a new model. 

Closely related to Chevrolet's Silverado HD, the Sierra 2500HD still functions as a sleek and stylish workhorse. While well-dressed and packed with features (especially in top Denali trim), the 2500HD stands ready for demanding action. In addition to the 3/4-ton 2500 series, the Sierra HD can be obtained in heavier-duty 3500 form.

Nothing of consequence has changed for the 2019 model year, apart from dropping the Regular Cab version. A redesigned heavy-duty Sierra is ready to debut as a 2020 model.

Like rival truckmakers, GMC offers plenty of choices: extended (Double Cab) or Crew Cab body; standard (6.5-foot) or long (8-foot) cargo bed; rear- or four-wheel drive. A quartet of trims stretches from humble work truck to unabashed luxury vehicle. Specifically, the Sierra 2500HD comes in base, SLE, SLT, and chrome-bedecked Denali form. The posh Denali comes only in Crew Cab form. A regular-cab version, lacking a back seat, is no longer offered.

Two big, powerful V-8 engines can power the Sierra 2500HD: one gasoline, and one a turbodiesel. The 6.0-liter gasoline V-8 develops 360 horsepower and 380 pound-feet of torque, while the 6.6-liter turbodiesel whips up 445 horsepower and a walloping 910 pound-feet.

Depending upon engine and configuration, a Sierra 2500HD can tow at least 13,000 pounds. Peak payload capacity can top 3,000 pounds.

Both engines mate with a 6-speed automatic transmission, but the turbodiesel gets a specially-engineered version, capable of accepting a torrent of torque.

The NHTSA gave the Sierra 2500HD a three-star rating for frontal impact, as well as four stars overall and for side-impact. No heavy-duty Sierra has been crash-tested by the IIHS.

Sierra 2500HD Denali trucks get forward-collision warnings, blind-spot monitors, and lane-departure warnings, along with a rear-seat reminder. These features are optional on SLE and SLT trim, but unavailable for the base model.

Available only in Crew Cab form, top-rung Denali models are almost the equivalent of a Cadillac-brand pickup. When loaded with options, a Denali can cost more than some high-end luxury cars.
