The GMC Sierra Heavy Duty line got a complete overhaul for the 2020 model year, with an updated exterior, interior, and a variety of new features as well. Now, however, we’re getting our first look at the latest 2020 GMC Sierra Chassis Cab.
Outside, we see the latest 2020 GMC Sierra Chassis Cab bears the same updated fascia as the standard Heavy Duty pickup models, with a large, rectangular grille, C-shaped lighting signatures, and sculpted lower styling lines between the bumper and central air intake.
Standard spec for the 2020 GMC Sierra Chassis Cab 3500 HD includes the naturally aspirated 6.6L V8 L8T gas engine, which mates to the MYD six-speed automatic transmission, and produces 401 horsepower and 464 pound-feet of torque. Meanwhile, the turbodiesel 6.6L V8 L5P Duramax is optional, connecting to the Allison 10-speed automatic transmission (which is not really an Allison) and producing 445 horsepower and 910 pound-feet of torque.
Other standard features include an external engine oil cooler, external transmission oil cooler, and a heavy-duty locking rear differential. Meanwhile, the list of optional extra includes an Autotrac two-speed transfer case and Integrated Power Take-Off.
For standard spec inside the cabin, there’s Bluetooth wireless connectivity for select phones, as well as the GMC Infotainment System with a seven-inch diagonal touchscreen. A set of vertical, high-visibility trailering mirrors help the driver stay aware of his or her surroundings. Things like dual-zone automatic climate control, 4G LTE WiFi, and heated bucket seats are optional.
All told, the 2020 GMC Sierra Chassis Cab is a good-looking rig, and it comes with a plethora of upfit options. These include:
- Ambulance and rescue
- Cargo body (box truck)
- Dump truck
- Platform / chassis cab
- Snow plow / spreader
