GMC has completely redesigned its heavy-duty type of pickups this season. The company has developed in the truck business for more than a century, and also the 2020 GMC Sierra 2500 may be the culmination of this extensive experience. “The all-new 2020 Sierra Durable is easily the most capable heavy-duty truck that we’ve ever offered,” states Duncan Aldred, v . p . of worldwide GMC.
Area of the Sierra HD’s makeover is a brand-new 6.6-liter V8 gas engine rated to create 401 horsepower. It’s a remarkable powerplant, mated to some smooth and time-tested six-speed automatic transmission. However, with this test, we purchased up a truck using the revised form of GMC’s proven Duramax 6.6-liter turbodiesel, that is now rated to create 445 horsepower and 910 lb-foot of torque. It’s also combined with the brand’s new 10-speed automatic. With this particular combination, the GMC Sierra 2500 competes with diesel-powered versions from the Ford F-250, RAM 2500, and it is mechanical twin, the Chevrolet Silverado 2500.
Huge Torque, Smooth Engine
With 445 horsepower and 910 lb-foot of torque, the GMC Sierra 2500’s Duramax isn’t probably the most effective turbodiesel engine offered within this class, however it isn’t far behind its rivals. The most powerful form of Ram’s Cummins turbodiesel makes 45 more horsepower compared to GMC, although it delivers 90 lb-foot less torque. With 475 hp and 1,050 lb-foot of torque, Ford’s new 2020 Power Stroke diesel may be the king from the class. Again, the Chevrolet Silverado Durable uses exactly the same Duramax engine because the GMC, therefore it provides the same power.
The engine, which has been available since 2017, is amazingly effective quickly the road. Its torque peaks just 1,600 revoltions per minute, providing you with a lot of twist once you touch the throttle. And also the new 10-speed automatic, that is smooth and responsive, is geared perfectly to benefit from the V8’s unique low-speed power. Even though the truck weighs an enormous 8,300 lbs, it may achieve 60 miles per hour within 6.5 seconds.
It wasn’t that lengthy ago that diesel-powered trucks of the size were raw work implements with loud engines and rough rides. That’s simply not the situation any longer. The 2020 GMC Sierra 2500HD is remarkably refined thinking about its size and capacity.
Such as the V6 turbodiesel now offered within the Sierra 1500, this Duramax V8 is smooth, refined, and shockingly quiet. It isn’t as hushed because the gas V8, however it doesn’t seem just like a Kenworth either. You won’t need to shout over its idle in the drive-through, and it is interior is amazingly quiet on the road, with hardly any engine or wind noise.
Comfortable Ride and large Capacity
During its redesign, GM’s engineers have fitted the 2020 GMC Sierra Durable with a brand new more powerful frame, that has elevated its towing and hauling ability. Probably the most capable models are now able to handle a gross combined weight rating as high as 43,500 lbs and tow a 35,500 lb-trailer. The 2500-series trucks also have become bigger rear axles along with a beefier gear looking for additional durability.
The wheelbase in our crew cab test vehicle can also be 5 inches more than before. It has elevated its rear seat space, that is now cavernous, and smoothed out its ride a little. GM’s Durable trucks have featured a completely independent front suspension for quite a while, however the new model maintains the torsion bar design. Even though the ride feels safe, it may be bouncy, and it’s less smooth because the ride within an equivalent Ford or Ram model. Still, its 3000-lb payload capacity is impressive, and also the Sierra handles well, with light steering as well as an agility that defies its weight and size.
Comprehensive AT4 Off-Road Package
Off-road ready packages have grown to be famous these kinds. Even though the Ram Power Wagon and Ford Tremor still own off-road capacity within the Durable pickup class, the Sierra 2500HD AT4 is much more able from the pavement than other Sierra models.
The 4-wheel drive AT4 features special Rancho shocks, optional 20-inch wheels, and 34-inch tall Goodyear Wrangler Trailrunner AT (18-inch tires are standard). A 2-speed transfer situation with low range can also be area of the package plus a locking rear differential, skid plates, hill-descent control to handle the truck’s speed lower steep grades, a Traction Select System, which tunes the traction control system for various surfaces, and recovery hooks in the bumper. I was also impressed using its surround camera system, which supplies 15 unique camera views helping you fit this animal in tight spots.
Simple to Drive Away Road
Even though the 2020 GMC Sierra 2500HD AT4’s off-road capacity takes place back by its low hanging front spoiler and optional side assist steps, the18 wheeler was fun to experience with at our local off-road park. About 10 inches of ground clearance below its front differential, there’s one inch greater than this past year. Regrettably, there’s only 9 inches of clearance within the rear, and it is rear differential is simple to tug over large obstacles.
The Sierra didn’t have problem tackling rocky trails and rutted washes, however in 2WD mode, wheel hop is a problem in deep sand. In four-wheel drive low, the torque from the Sierra’s diesel, its automatic locking rear differential, and it is knobby Goodyears made steep climbs easily, nevertheless its chassis and the body structure don’t appear as solid because the Ram’s or even the Ford’s over rutting fire roads. There’s more quiver within the GMC’s cab than there’s within the others, and it is mirrors and controls vibrate.
Awesome Multifuction Tailgate
When Ford began making the human body and bed and it is F-Series pickups from aluminum several years ago, other truck manufacturers began getting good seriously interested in exotic materials that save weight and add strength. Today the Sierra’s hood, doorways, and tailgate are aluminum, though all of those other truck’s is still steel. GMC provides an optional CarbonPro composite bed, which consists of carbon fibre composite, on its half-ton 1500 model, although not its Durable trucks.
SLT, AT4, and Denali models come standard with GMC’s MultiPro Tailgate, that is a awesome and clever design with six functions and positions together with a load-stop, a standing workstation, along with a step. The Sierra’s bedside steps and cornerstep rear bumper also make bed access simpler. GMC has additionally decreased the truck’s bed lift-tall by one inch when compared to 2019 Sierra Durable, which makes it simpler to load cargo and hitch a fifth-wheel or gooseneck trailer.
Comfortable and Functional Interior
The GMC’s cabin feels safe, attractively, and functional having a giant center console, huge door bins, two enormous cupholders, two gloveboxes, and very comfortable seats. It’s also correctly ergonomic having a height-adjustable driver’s seat, a tilt and telescopic controls, and a mixture of digital and analog gauges. Left from the controls really are a push-button parking brake and buttons to manage the 4WD system, which engages easily. Our test truck also featured heated and cooled seats, a heated controls, and Apple CarPlay and Android Auto. A built-in Wi-Fi hotspot is standard of all models and wireless phone charging can be obtained.
Regrettably, the Sierra’s cabin feels a little cheap and dated for this kind of costly truck, because of its extensive hard plastics and smallish 8-inch touchscreen. The Ram’s interior continues to be the most luxurious within this class, with impressive detailing along with a massive optional touchscreen.
A Extended Report on Advanced Driver Aids
Ford was once leading the safety tech race in this particular class, but GMC has taken up. Our Sierra AT4 was filled with high-tech driver aids and safety systems.
Optional packages around the test vehicle incorporated a forward collision warning, automatic emergency braking with pedestrian recognition, automatic high beams, lane-keeping assist with a lane-departure warning, adaptive cruise control, back and front parking sensors, a blind-place monitor getting a rear cross-traffic alert, and GMC’s
