All-New 2020 GMC Sierra HD

Engineered to conquer, the soon-to-be-released 2020 GMC Sierra HD is a vehicle brimming with increased durability and attention to detail to give you full control over the terrain.

Available late this summer, here are the standout aspects of the 2020 GMC Sierra HD that you need to know before getting your hands on one.

It’s Equipped With the First Ever 10-Speed Allison Transmission

You’re assured heavy-duty strength with the 2020 GMC Sierra HD thanks to the first ever 10-speed Allison Transmission.

Founded in 1915, Allison Transmission is the largest provider of commercial-duty, fully-automatic transmissions worldwide. Their transmission combines enhanced performance and fuel economy, improving driver comfort and control with a quality reputation for uptime and reliability.

This transmission combines with the available 6.6L Duramax Turbo Diesel V8 for superior power delivery. The turbo diesel produces 445 horsepower and 910 lb.-ft. of torque with the transmission, the first of its kind in the heavy-duty pick-up segment.

This unprecedented 10-speed transmission has closer gear spacing, which allows the engine to operate in an optimal range on a regular basis through varying load and terrain conditions. These features, combined with fortified components used throughout Sierra Heavy Duty’s driveline, provide maximum torque to the wheels at all times, offering drivers maximum control and balance.

Boost Your Cargo Capabilities with MultiPro Tailgate

With the 2020 GMC Sierra HD’s MultiPro Tailgate technology, you essentially get two tailgates in one and can position it for use in multiple ways. MultiPro’s design consists of a primary gate, which is hinged like a conventional tailgate, and a smaller inner gate, hinged on the primary gate panel.

As a result, raising and lowering these tailgate panels in different combinations allows MultiPro to take on varying roles, including being a bed extender to an entry step.

Thanks to the world’s first six-function MultiPro tailgate, the 2020 GMC Sierra HD comes packed with improved cargo box accessibility and functionality. Your cargo box functionality improves by adapting to your needs using six different functions, making loading and unloading much more simple.
