GMC's new durable pickups bring higher improvement, substantial capabilities, and smarter convenience and trailering functions. The 3.6-liter V6 does its job well with reliable power and torque readily available. I'm constantly nervous when we see a new 9-speed system. Commonly adjusted towards fuel efficiency, these gearboxes typically discover themselves confused regarding what gear to pick throughout difficult velocities. Burying the accelerator pedal on the 2020 GMC Acadia AT4 didn't cause any hesitation, though, as the unit shifts quickly and flawlessly through gears.

New Turbodiesel

The only cars provided with the new turbodiesel for on-road screening was a Denali, which is the range-topping model in the Sierra 1500 lineup. The disadvantage to GMC's choice to not make any other changes to the 2020 lineup is the fact that the Denali's interior remains extremely unimpressive, specifically when compared to the Ram 1500s. This is especially egregious when you think about that Ram is not clearly playing to a premium niche the method GMC is.

The Engine

The basic engine for the Sierra 2500HD is a 6.6-liter gasoline V8, great for 401 horse power and 464 lb-ft. of torque. The model we tested included the 6.6-liter Duramax turbo-diesel V8, which outputs 445 horsepower at 2,800 RPM, and a staggering 910 lb-ft. of torque at a low 1,600 RPM. This isn't by any indicates a straight-line bandit, but the diesel 2500HD drove around the foothills of Yellowstone National Park effortlessly and blended in perfectly with the other durable trucks in the area.

Powertrain System

When it concerns the powertrain, things will remain practically the very same. The 2020 Sierra 1500 will continue with basic 4.3-liter V6, which is good for about 280 horsepower. Of course, a new 2.7-liter four-cylinder is in the deal also. This one delivers around 310 horsepower and 350 pound-feet of torque. Two familiar V8 systems remain in the deal also. A 5.3-liter unit benefits about 355 horse power, while a bigger 6.2-liter engine delivers around 420 hp. Finally, there is a 3.0-liter turbodiesel engine, which provides around 282 horsepower and 450 pound-feet of torque.

The Wheelbase

Longer in wheelbase (rear legroom grows almost three inches), these crew cab models shed 450 pounds over their predecessors-- the outcome of a hotly-debated choice to utilize aluminum for some of the body panels (hood, doors, tailgate). GMC claims its 5'8 ″ short box is the most abundant in the market (62.9 cubic feet), a lot more so than the 6'6 ″ long boxes found on Ford and Ram crew taxis. The jury's out, a minimum of for this author, on the visual appeal of those strange wheel wells. Inside, it's again a case of evolution over transformation. A line of driver-assist and benefit switches still decorates the bottom of the aluminum-trimmed center stack.

Like its Chevrolet Silverado 1500 stablemate, the 2020 GMC Sierra 1500 is a full-size pickup truck that is available in crew-cab, double-cab and regular-cab configurations. Not a surprises there. For 2020, there are some brand-new trim choices of its brand-new 5202 led bulb conversion package and, most notably, a new powerplant. Together with the previously available gas engines, the Sierra 1500 now offers an optional turbocharged diesel inline-six engine. The fiercely anticipated 3.0-liter Duramax diesel motor alternative has actually been discussed for over a year.
