The GMC Sierra 1500 was redesigned last year and it’s entering 2020 with a host of updates that aim to make the pickup even more appealing.
On the tech front, the 2020 Sierra will be offered with an upgraded ProGrade Trailering System. Like the system offered on the 2020 Sierra HD, it supports up to 15 different cameras including those mounted on trailers. Speaking of which, the model now offers a “transparent trailer view” function which allows drivers to ‘see through’ their trailer thanks to two cameras and some special software tricks.
The truck also gains an updated Trailering App which allows users to create and edit trailer profiles through the myGMC mobile app. Owners will also be able to share their trailer profiles and receive maintenance reminders and mileage information.
Other tech updates include an Adaptive Cruise Control Camera system which will be available on SLT, AT4 and Denali. The system automatically adjusts the Sierra’s speed to match the flow of traffic and it can even bring the truck to a complete stop.
Engine options carryover, but the 5.3-liter V8 can now be paired to a ten-speed automatic transmission. The gearbox is standard on the AT4 and Denali, but optional on SLE and above models with four-wheel drive.
The 3.0-liter turbodiesel inline-six sees greater availability as it will now be available on AT4 and Denali models equipped with the CarbonPro bed. This is a minor change, but it means diesel fans can now get a carbon fiber bed to go with their Duramax engine which produces 277 hp (207 kW / 281 PS) and 460 lb-ft (623 Nm) of torque.
Since the truck was all-new for 2019, styling changes are limited. However, the Sierra AT4 CarbonPro Edition gets a slight makeover as it now features a black chrome grille surround, modified badges and black exhaust tips.
Last but not least, trailer tow mirrors are now available as a free-flow option and the Sierra Elevation will be offered in a crew cab configuration.
