2020 GMC Sierra 2500 Diesel Road Test and Review

GMC has completely redesigned its heavy-duty kind of pickups this year. The organization has elevated the truck business for over a century, as well as the 2020 GMC Sierra 2500 could be the culmination of the extensive experience. “The all-new 2020 Sierra Durable is regarded as the capable heavy-duty truck that we’ve ever offered,” states Duncan Aldred, v . p . of worldwide GMC.

Part of the Sierra HD’s makeover is a-new 6.6-liter V8 gas engine rated to produce 401 horsepower. It’s a outstanding powerplant, mated with a smooth and time-tested six-speed automatic transmission. However, with this particular test, we purchased up a truck while using revised type of GMC’s proven Duramax 6.6-liter turbodiesel, that’s now rated to produce 445 horsepower and 910 lb-feet of torque. It’s also combined with brand’s new 10-speed automatic. Using this combination, the GMC Sierra 2500 competes with diesel-powered versions in the Ford F-250, RAM 2500, which is mechanical twin, the Chevrolet Silverado 2500.

Huge Torque, Smooth Engine

With 445 horsepower and 910 lb-feet of torque, the GMC Sierra 2500’s Duramax isn’t most likely the very best turbodiesel engine offered in this particular class, nevertheless it isn’t far behind its rivals. Probably the most effective type of Ram’s Cummins turbodiesel makes 45 more horsepower when compared with GMC, even though it delivers 90 lb-feet less torque. With 475 hp and 1,050 lb-feet of torque, Ford’s new 2020 Power Stroke diesel could be the king in the class. Again, the Chevrolet Silverado Durable uses the identical Duramax engine since the GMC, so that it offers the same power.

The engine, that has been available since 2017, is very effective rapidly the road. Its torque peaks just 1,600 revolutions per minute, supplying you with many different twist when you touch the throttle. As well as the new 10-speed automatic, that’s smooth and responsive, is geared perfectly to take advantage of the V8’s unique low-speed power. Although the truck weighs a massive 8,300 lbs, it might achieve 60 mph within 6.5 seconds.

Incredible Refinement

It wasn’t that extended ago that diesel-powered trucks from the size were raw work implements with loud engines and rough rides. That’s not the problem any more. The 2020 GMC Sierra 2500HD is remarkably refined considering its size and capacity.

Like the V6 turbodiesel now offered inside the Sierra 1500, this Duramax V8 is smooth, refined, and shockingly quiet. It isn’t as hushed since the gas V8, nevertheless it doesn’t appear as being a Kenworth either. You won’t have to shout over its idle within the drive-through, which is interior is very quiet around the road, with almost no engine or wind noise.

Comfortable Ride and enormous Capacity

During its redesign, GM’s engineers have fitted the 2020 GMC Sierra Durable having a completely new more effective frame, which has elevated its towing and hauling ability. Most likely probably the most capable models can now handle a gross combined weight rating up to 43,500 lbs and tow a 35,500 lb-trailer. The 2500-series trucks also provide become bigger rear axles plus a beefier gear searching for further durability.

The wheelbase within our crew cab test vehicle may also be 5 inches greater than before. It’s elevated its rear seat space, that’s now cavernous, and smoothed out its ride just a little. GM’s Durable trucks have featured an unbiased front suspension for a long time, nevertheless the new model maintains the torsion bar design. Although the ride feels safe, it might be bouncy, and it’s less smooth since the ride inside an equivalent Ford or Ram model. Still, its 3000-lb payload capacity is impressive, as well as the Sierra handles well, with light steering plus an agility that defies its weight and dimensions.

Comprehensive AT4 Off-Road Package

Off-road ready packages are becoming famous these types. Although the Ram Power Wagon and Ford Tremor still own off-road capacity inside the Durable pickup class, the Sierra 2500HD AT4 is a lot more able in 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 may also be part of the package along with a locking rear differential, skid plates, hill-descent control to handle truck’s speed lower steep grades, a Traction Select System, which tunes the traction control system for a number of surfaces, and recovery hooks within the bumper. I had been also impressed having its surround camera system, which gives 15 unique camera views assisting you fit this animal in tight spots.

Easy to Drive Away Road

Although the 2020 GMC Sierra 2500HD AT4’s off-road capacity happens back by its low hanging front spoiler and optional side assist steps, your truck was fun to see with at our local off-road park. About 10 inches of ground clearance below its front differential, there’s 1 inch more than a year ago. Regrettably, there’s only 9 inches of clearance inside the rear, which is rear differential is straightforward to drag over large obstacles.

The Sierra did not have problem tackling rocky trails and rutted washes, in 2WD mode, wheel hop is a concern in deep sand. In four-wheel drive low, the torque in the Sierra’s diesel, its automatic locking rear differential, which is knobby Goodyears made steep climbs easily, nonetheless its chassis and the entire body structure don’t appear as solid since the Ram’s or perhaps the Ford’s over rutting fire roads. There’s more quiver inside the GMC’s cab than there’s inside the others, which is mirrors and controls vibrate.

Awesome Multifuction Tailgate

When Ford started making the body and bed which is F-Series pickups from aluminum in the past, other truck manufacturers started receiving targeted intent on exotic materials that save weight and add strength. Today the Sierra’s hood, doorways, and tailgate are aluminum, though all individuals other truck’s continues to be steel. GMC offers an optional CarbonPro composite bed, featuring its graphite composite, on its half-ton 1500 model, while not its Durable trucks.

SLT, AT4, and Denali models come standard with GMC’s MultiPro Tailgate, that’s a awesome and clever design with six functions and positions plus a load-stop, a standing workstation, plus a step. The Sierra’s bedside steps and cornerstep rear bumper also make bed access simpler. GMC has furthermore decreased the truck’s bed lift-tall by 1 inch in comparison with 2019 Sierra Durable, that makes it better to load cargo and hitch a fifth-wheel or gooseneck trailer.

Comfortable and Functional Interior

The GMC’s cabin feels safe, attractively, and functional getting a huge center console, huge door bins, two enormous cupholders, two gloveboxes, and incredibly comfortable seats. It’s also properly ergonomic getting a height-adjustable driver’s seat, a tilt and telescopic controls, and a combination of digital and analog gauges. Left in the controls certainly are a push-button parking brake and buttons to handle 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 models and wireless phone charging could be acquired.

Regrettably, the Sierra’s cabin feels just a little cheap and dated for this sort of pricey truck, due to its extensive hard plastics and smallish 8-inch touchscreen. The Ram’s interior remains probably the most luxurious in this particular class, with impressive detailing plus 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
