The full-size pickup segment seems to be getting more and more popular, while the entrants in this class keep getting better and better. The 2020 GMC Sierra 1500 is one of the popular entrants in this class. This year, the Sierra 1500 brings even more to the table. Most notably a new available turbocharged diesel inline-six engine joins the Sierra’s powerplant lineup. There was some buzz that this diesel unit would appear on last year’s model, but according to the Salem GMC dealer, the release of this engine was delayed due to a holdup in the certification process.
They say good things are worth waiting for, and that’s certainly true with the Sierra 1500’s new Duramax diesel engine. While other automakers equip their pickups with a V6 diesel block, the Sierra’s diesel is a straight-six. The GMC dealer Salem explained that while a flat-six is a bit longer than a V6, it produces more torque and runs smoother. The diesel engine has a maximum towing capacity of 91,000 pounds and a maximum payload capacity of 1,830 pounds.
The automotive experts at Motor Trend wrote this about the 2020 GMC Sierra 1500: “How does it feel on the road? In two words, smooth and responsive. Of course, we're guessing a lot of that has to do with the computer software integration with the new 10-speed transmission (also newly available for 2020 with the DFM 5.3-liter V-8), which never gave us any harsh shifts or hunts during our drive routes. ... we found the acceleration feel to be impressive.”
The 2020 GMC Sierra 1500 is available in six trim levels: Base, SLE, Elevation, SLT, AT4 and Denali. Buyers can choose from three cab configurations and three cargo box sizes. There are six engines on offer:

6.2-liter V8 engine with Dynamic Fuel Management generating 420 hp and 460 lb-ft of torque, connected to a 10-speed automatic gearbox

GMC's ProGrade trailering system utilizes an arrangement of cameras, available tow mirrors, an integrated trailer brake controller and parking brake assist to make it easy to pull a trailer. The system can pull up 15 different camera angles on the center touchscreen. There's even an available camera that displays the inside of the trailer.
The MultiPro tailgate can be used as a one-piece or separately to create a step. The optional CarbonPro bed is constructed from a mix of cut carbon and resin. According to GMC, it’s more resistant to impact and scratches than other beds.
