2020 GMC Sierra Heavy Duty Truck Introduction

In the new Sierra Heavy Duty, the form and function come together and include:

An advanced ProGrade Trailer system with 15 camera views leading in its class; including a first segment transparent trailer view so that you can see a trailer on the tow truck almost completely.

The intelligent trailer, designed to integrate the iN Command® control system from ASA Electronics 2, allows you to monitor and control the selection functions of trailers with compatible equipment via the myGMC mobile app 3.
A part-specific, 15-inch diagonal overhead display that provides useful trailer information including vehicle speed, navigation information, and a tilt indicator display for the road class.
The first Rear Camera Mirror in the available segment.
The world's first six-functional trunk lid, the MultiPro, provides easier loading, unloading and bearing access and is available at all floor levels.

A wider, commanding design that gives more space to cargo and passengers.
Best-in-class Crew Cab front headroom and footwell for driver and other front row passengers.
The legendary 6.6L Duramax turbo diesel is a completely new, segment-first, Allison 10-speed automatic transmission.
For those who want improved off-road driving capabilities, the GMC strengthens the new AT4 brand with an all-new Sierra AT4 Heavy Duty, available in Crew Cab configurations available in both 2500 and 3500 single rear wheel offerings.

The industry-leading 15 unique camera images, including the first transparent trailer image in the industry, optimize the driver's view of trucks and compatible trailers to provide additional confidence during traction. The revolutionary transparent trailer feature uses the rear-mounted camera and an existing auxiliary camera mounted behind the trailer. The resulting indicator helps the driver to see the trailer 4 almost fully when driving in the parking lots, entering traffic or frequently returning.

2020 Sierra HD owners are designed to provide access to the features of the iN mand Command® control system in ASA Electronics 2 via compatible Android and iOS smartphones or via the myGMC mobile app
