2020 GMC Sierra 1500 AT4 First Drive Review

GMC's brand-new sturdy pickups bring higher refinement, huge abilities, and smarter convenience and trailering functions. The 3.6-liter V6 does its task well with reputable power and torque readily available. I'm always nervous when we see a new 9-speed system. Typically adjusted towards fuel effectiveness, these transmissions frequently discover themselves confused as to what gear to select during hard velocities. Burying the accelerator pedal on the 2020 GMC Acadia AT4 didn't cause any doubt, though, as the unit shifts rapidly and seamlessly through equipments.

New Turbodiesel

The only vehicles used with the new turbodiesel for on-road testing was a Denali, which is the range-topping model in the Sierra 1500 lineup. The downside to GMC's decision to not make any other changes to the 2020 lineup is the reality that the Denali's interior remains extremely unimpressive, especially when compared to the Ram 1500s. This is particularly egregious when you consider that Ram is not clearly playing to a premium niche the method GMC is.

The Engine

The standard engine for the Sierra 2500HD is a 6.6-liter gasoline V8, good for 401 horsepower and 464 lb-ft. of torque. The design we sampled included the 6.6-liter Duramax turbo-diesel V8, which outputs 445 horse power at 2,800 RPM, and a shocking 910 lb-ft. of torque at a low 1,600 RPM. This isn't by any suggests a straight-line outlaw, however the diesel 2500HD drove around the foothills of Yellowstone National Park easily and blended in completely with the other sturdy trucks in the area.

Powertrain System

When it pertains to the powertrain, things will remain pretty much the very same. The 2020 Sierra 1500 will continue with standard 4.3-liter V6, which benefits about 280 horse power. Naturally, a new 2.7-liter four-cylinder is in the deal as well. This one provides around 310 horsepower and 350 pound-feet of torque. Two familiar V8 units remain in the deal too. 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 delivers around 282 horse power and 450 pound-feet of torque.

The Wheelbase

Longer in wheelbase (rear legroom grows nearly 3 inches), these crew cab models shed 450 pounds over their predecessors-- the outcome of a hotly-debated decision to use aluminum for some of the body panels (hood, doors, tailgate). GMC declares 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 cabs. The jury's out, a minimum of for this author, on the visual appeal of those odd wheel wells. Inside, it's again a case of evolution over transformation. A line of driver-assist and convenience switches still adorns 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 offered in crew-cab, double-cab and regular-cab setups. No surprises there. For 2020, there are some new trim alternatives of its brand-new 5202 led bulb conversion set and, most notably, a new powerplant. Together with the previously readily available gas engines, the Sierra 1500 now provides an optional turbocharged diesel inline-six engine. The hotly anticipated 3.0-liter Duramax diesel engine alternative has actually been discussed for over a year.
