2020 GMC Sierra HD Diesel

2020 GMC Sierra HD Diesel The new 2020 GMC Sierra pickup has just crested the skyline, warm on the heels of the redesigned Chevrolet Silverado HD. As you might expect, the style is the biggest differentiator between the two trucks, which is either a good or a bad thing depending on how you feel about the Silverado HD polarizing new face. The new GMC also introduces some optional features that are said to help with towing, transportation, and other truck tasks.

As before, the Sierra HD range includes models 2500 and 3500 and offers a multitude of bed and cabin configurations. Similar to what we have seen with the different levels of Silverado HD trim, the different Sierra models-that reflect the light-Duty range Sierra 1500 of SLE, SLT, off-road-oriented AT4, and Denali models fully loaded-all seem quite different from each other.



The Denali has the chrome front grille. The AT4 has bits of dark outer trim, an off-road suspension installation with Rancho shocks and a rear locking differential, and all-terrain tires. Options include Sierra’s light MultiPro hatchback with some different positions, a 15-inch head-up screen, and a camera system that displays different views of the trailer. It is not clear at this stage which of these options will be offered on the Silverado HD and which will be reserved only for the GMC.

While the outside will be different from the Silverado 2500 HD, under the hood will be similar. This means that the GMC will use the 6.6-liter V8 diesel and the 6.0-liter V8 petrol to power the truck. The paddle will probably receive a refresh to pump more power and torque, which will help the truck improve its transport capability-a must for any new heavy pickup. The gasoline engine must remain the entry-level powertrain.

The six-speed automatic transmission for intensive use will remain unchanged, as competitors in the truck still use six-speed gearboxes. The Allison 1000 6-Speed automatic box will be optional. In addition, the new 10-speed Hydra-Matic automatic transmission can appear as an option. 

Chevy already has a teaser for the Silverado 2500, and now we have a plethora of test mules on the road. It’s hard to believe both the Sierra trucks and Silverado HD only start early next year – probably the Detroit or Chicago auto shows. After the revelation, both will be on sale later in 2019.

As for the dirty pieces of the Sierra HD, there is not much variation in the new Silverado HD powertrain offer, which includes a petrol V-8 and a turbo-diesel V-8. The diesel is the same 6.6-liter of the current truck unit, making the same 445 horsepower and 910 lb-ft of torque, but now coupled to an automatic Allison 10-speed box to replace the old six gears. The new petrol engine, a new 6.6-liter V-8 with direct injection, paired with a six-speed automatic transmission and made 401 horsepower and 464 lb-ft of torque.

The payload and towing capabilities increase, with a claimed maximum towing capacity of 35 500 pounds with the optional configuration of the fifth wheel mounted on the bed. GM trucks will still have their work cut for them beating the new HD RAM trucks, which offer up to 1000 lb-ft of torque, and Ford F-Series Super Duty mics, which have been revised to 2020.

Pricing is not yet available but should be similar to the current Sierra HD, which starts at $39 695. GMC says the 2020 Sierra HD will be on sale in the second half of this year.
