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.
Inside, the automaker has made it roomier than before. The headroom, legroom and seating height all got better. The Denali gets exclusive leather seats, open-pore wood accents, and dark-finish aluminum trim.
The AT4 Heavy Duty comes with its own set of features including dark-chrome exterior finishes, a grille-surround
polished in body color, and dark & textured aluminum textures on the steering wheel, center stack and sill plates. Moreover, the Sierra AT4 Heavy Duty boasts an off-road suspension, Rancho shocks, skid plates, Eaton locking rear-differential and regular 18-inch wheels with Michelin all-terrain tires.
The 2020 GMC Sierra Heavy Duty will go on sale this summer competing against the likes of Super Duty F-250 and F-350, and new Ram 2500 and 3500 Heavy Duty. The pricing details are unknown. However, we know the 2018 2500 Crew Cab starts at AED 202,000.
