THE NEW 2020 GMC SIERRA 2500/3500HD PICKUP TRUCKS
The new 2020 Sierra HD is the perfect balance of luxury and durability. It has a longer wheelbase, a taller hood, and greater overall height than its predecessor.
The interior was also redesigned, and comes with the latest infotainment capabilities and lots of new technology that offers more convenience when you’re on the road.
The new 2020 Sierra HD introduces its all-new 6.6-liter gasoline V8 as the base engine, with 22% more torque and an 18% higher towing capacity than the outgoing
6.0-liter Vortec V8. There are now five trims available, including the new AT4 trim for the serious off-roader.
