GMC has lifted the veil on the all-new
2020 Sierra Heavy Duty. GMC has outfitted the heavy duty pickup with a plethora of new
features. One of the most important updates is the ProGrade Trailering System.
This system provides the driver with 15 camera
views, including a transparent trailer view that allows those behind the wheel
to tow with ease. Other features of the ProGrade Trailering System are a
Trailer Light Test, Trailer Electrical Diagnostics, Trailer Tire Pressure and
Temperature Monitoring, Pre-Maintenance Reminders and a Departure Checklist.
A host of other technologies have been added to the
Sierra Heavy Duty to make towing a breeze. For example, there’s an Auto
Electric Park Brake, Park Grade Hold Assist, Integrated trailer brake
controller, Hill Start Assist, Hill Descent Control, Trailer Sway Control, Auto
Grade Braking, Diesel Exhaust Braking, and a Tow/Haul mode. To put it simply, the
new Sierra Heavy Duty thrives when there’s something hooked up to its rear.
An eye-catching design also set the new Sierra Heavy
Duty apart from the old model. There’s a massive front grille, headlights with
GMC’s ‘light blades’, LED fog lamps, and roof marker lights on all
dual-rear-wheel HDs and Sierra HD Denali models where they’re permitted by law.
It’s not just the exterior design that makes the new
pickup stand out. The vehicle itself is actually longer and taller than the
previous model. All 2020 GMC Sierra Heavy Duty models use a large 6.6-liter
turbo-diesel Duramax engine that delivers 445 hp and 1233 Nm of
torque. This engine is mated to an all-new 10-speed Allison automatic
transmission. With its potent powertrain, the pickup can tow in excess of 13,607 kg.
GMC has also updated the Sierra AT4 HD for the 2020
model year. The AT4 is the more off-road focused Sierra Heavy Duty variant and
includes a number of dark chrome exterior touches as well as bespoke front and
rear bumpers. Inside, the vehicle includes darkened trim, textured aluminum
finishes, Jet Black trim, leather seats, and embroidered AT4 badges on the
headrests.
The AT4 also includes off-road suspension, bespoke
18-inch wheels, a 15-inch Head-Up Display, and Traction Select System with a
specific Off-Road mode. Sales of the 2020 Sierra Heavy Duty will start later this year in
2500HD and 3500HD configurations. Prices have yet to be announced.
