2020 GMC Sierra 2500/3500 Walk-Around: Video

All the redesigned heavy-duty pickup trucks are destined for U.S. showrooms this year, and we’ve had a good look at two of the latest — the . Just like the trucks, the redesigned GMCs sit on a new frame, feature all-new styling, new interiors, new powertrains and increased capability.

You can choose from two powertrains: a brand-new 6.6-liter gasoline V-8 or a with an unchanged 445 horsepower and 910 pounds-feet of torque. The gas engine rated at 401 hp and 464 pounds-feet of torque gets a six-speed automatic transmission, while the diesel gets a new 10-speed Allison automatic. The AT4’s four-wheel-drive system now has an automatic mode, with selectable terrain adjustments for different terrains. The 3500 is rated to tow up to 35,500 pounds, according to GMC, a big bump from the outgoing truck’s maximum numbers. And out back, there’s the same you can get on the light-duty Sierra.

Inside, it doesn’t look any different from the Silverado HD trucks — or even all that different from the light-duty . The big news is the replacement of the All Terrain trim with the new-for-2020 AT4 off-road version. Like the , the HD version gets a host of unique visual upgrades to the grille, trim and interior, but it also gets mechanical upgrades like an off-road suspension with Rancho shocks, extra skid plates, a locking rear differential, Off-Road mode for the Traction Select System, hill descent control, hill start assist, a head-up display with an off-road inclinometer and surround-vision cameras.

Check out the video above to see a walk-around of the new 2020 GMC Sierra 2500 and 3500.
