The American automaker has introduced the next generation 2020 GMC Sierra Heavy Duty pickups alongside an all-new AT4 version taking design cues from the upgrades made last year. The heavy-duty trucks feature the MultiPro six-function tailgate, rear-camera mirror, and ProGrade Trailering system. All these features are borrowed from the redesigned flagship Sierra 1500 light-duty pickup introduced last year. GMC AT4 off-roading brand brings the all-new Sierra AT4 Heavy Duty in crew cab configurations.

“The all-new 2020 Sierra HD is the most capable heavy-duty truck that we’ve ever offered,” said Duncan Aldred, vice president of Global GMC. “For customers who demand a premium, innovative heavy-duty truck that supports their passions, the next-generation Sierra HD can pull like a pro.”

The 2020 GMC Sierra Heavy Duty is taller and longer than the previous generation models. The truck is powered by a 6.6-liter Duramax turbo-diesel cranking 445 hp and 910 pound-feet of torque. The engine is paired with an all-new 10-speed Allison automatic transmission. Thanks to the larger frame and more powerful engine, the Sierra HD can tow over 30,000 pounds. GMC demonstrated the towing prowess by pulling an 80-foot yacht weighing 225,000 pounds with the aid of a fifth-wheel hitch.
