2020 GMC Sierra Heavy Duty Truck Introduction https://goo.gl/2xsDNN

Whether at home, at work, or away from it all, you have big expectations of what a heavy duty pickup truck should be. At GMC, we set out to not only meet those expectations – but also set a new standard of what a heavy duty pickup can be – with the Next Generation 2020 GMC Sierra Heavy Duty.

Available in ¾-ton 2500, 1-ton 3500 single rear wheel, and 1-ton 3500 dual real wheel configurations, the 2020 Sierra Heavy Duty brings the clever thinking, bold design, and attention to detail expected of a modern GMC to the heavy duty pickup segment – all while providing incredible performance, enhanced trailering capabilities, and a unique, refined, yet distinctly heavy duty personality.
We set new standards for smart capability, bold design, and advanced technologies in the half-ton pickup space with the 2019 Sierra 1500,” says Jaclyn McQuaid, Sierra Heavy Duty Chief Engineer. “We wanted to do the very same in the heavy duty space, while simultaneously increasing strength and performance. We were determined to make this truck as driven and capable as our customers.”

POWER BEYOND REPROACH
Sierra has built a reputation for incredible performance, especially when it comes to diesel heavy duty trucks. For 2020, Sierra Heavy Duty not only continues that tradition – it raises it to new levels.
Sierra Heavy Duty’s available 6.6L Duramax turbo-diesel V8 delivers 445 hp and 910 lb-ft of torque Engineers worked to make this already powerful engine perform more efficiently by both increasing cooling capacity by way of a larger radiator and fan, and improving the air induction system. A dual-path intake system draws dense, cool air through both the hood scoop and the front grille in order to optimize performance.

The new Sierra Heavy Duty marks the introduction of an all-new Allison® 10-speed automatic transmission – the first-ever 10-speed automatic transmission offered in the heavy duty pickup segment. The new 10-speed transmission provides closer gear spacing than before, allowing the engine to operate in an optimal range at all times with varying load and terrain conditions.

The Duramax/Allison combination also incorporates an integrated engine exhaust brake, which leverages the engine’s backpressure and the Sierra Heavy Duty’s driveline components to help control the speed of the truck and trailer while descending, reducing the need to use service brakes on long, steep grades. The exhaust brake is also tied to the cruise control system, allowing a set speed to easily be maintained, even over hilly terrain.

Across the board, rear axles have larger, stronger components than ever before in order to both increase gross axle weight ratings (GAWR) and effectively deliver as much torque to the ground as possible.
