2020 GMC Sierra 1500 Overview

For 2020, the Sierra 1500 features a number of upgrades to keep it at the forefront of the full-size light-duty pickup truck market.

Shoppers can choose from a range of engines, including a turbo 4-cylinder, V6, turbodiesel, and two V8s. The base trim comes with a 4.3-liter V6 that makes 285 horsepower and 305 pound-feet of torque and pairs to a 6-speed automatic. Mid-range trims come standard with a 2.7-liter turbocharged 4-cylinder engine that puts out 310 hp and 348 lb-ft and sends power through an 8-speed automatic transmission.

Two V8 engines are available on the Sierra 1500. The 5.3-liter V8, which makes 355 hp and 383 lb-ft, is now available with a 10-speed automatic transmission, offering a blend of efficiency and enhanced power management. The other V8 offered is a 6.2-liter engine, which makes 420 hp and 460 lb-ft through a 10-speed automatic transmission.

New for 2020 is the expanded availability of the 3.0-liter Duramax turbodiesel inline 6-cylinder engine. It puts out 277 hp and 460 lb-ft and pairs with the 10-speed automatic. This diesel engine is available on the CarbonPro Edition Denali, AT4, SLT, Elevation, and SLE trims. Any of these engines can be paired with rear-wheel drive (RWD) or 4-wheel drive (4WD) with low range.

The truck is available in single cab, double cab, and crew cab variants. The single cab comes with a front bench seat, providing seating for up to three. This standard bench seat is also found in the base trims of the double cab and crew cab of the Sierra, providing seating for up to six. Mid-to-high-grade trims swap out the front bench seat for front captain's chairs.

The GMC Sierra is the first truck offered with an available carbon-fiber bed, which is extremely light and strong and not susceptible to the corrosion risks of a traditional steel bed. This bed can be found on the CarbonPro edition of the Sierra 1500 AT4. Another innovation is the MultiPro tailgate design, which features six positions and allows for easier loading and access via a step system for getting up into the truck bed.

Inside, the Sierra features a dash design from the 2019 update. At the heart of the dash is the touchscreen infotainment system. A 7-inch touchscreen comes standard, while an 8-inch touchscreen is available. Both screens support Apple CarPlay and Android Auto. The Sierra is also available with a multi-color head-up display (HUD).

For those looking to take their truck off the beaten path, the Sierra is available with the AT4 trim. It is an off-road-focused trim, with a blacked-out grille and red tow hooks. The AT4 features a 2-inch factory-installed lift kit, more aggressive off-road tires, additional underbody skid plates, and an electronically locking rear differential.

The Sierra comes standard with a reversing camera and is now available with camera-based adaptive cruise control. It also provides apps specifically designed for towing that can be integrated with your smartphone. Drivers can create a profile for specific trailers, including key weight information, which can be transferred to other users. This app can also send reminders for maintenance.
