2022 GMC Sierra 2500HD Regular Cab Diesel Release date:

 It is speculated to arrive at the showrooms by the third quarter of 2021.

What sets it apart from the regular version is the diesel engine it offers. Both trims of the 2021 GMC Sierra 2500HD Regular Cab Diesel are powered by a 6.7L PowerStroke V8 Turbo Diesel engine which churns out 475 horsepower and a colossal torque of 1050 lb-ft. Front-wheel drive is standard across the lineup however the all-wheel-drive system can be had by paying additionally. Power is sent to the wheels via a TorqShift 10-Speed Automatic transmission which gets the job done very well. This V8 engine has a strong character with an insane amount of torque. It delivers a lot of low-end grunts which manages to take the vehicle from 0-60 mph in 6.5 seconds and can finish a quarter-mile in 15.6 seconds which is seriously phenomenal for a diesel-powered truck. They have tuned the engine to the maximum limits and brought the best out of the engine.

 The GMC Sierra also performs great on the road and never annoys you with loud noises resulting in an amazing driving experience. The same goes for the 10-speed automatic transmission as it is pretty smooth and seamless. The only problem we could find in it was its handling, which is a bit hefty due to its size, which directly affects the vehicle within the corners. However, when it comes to off-road, it is where it comes into its own. The AWD version has some great off-roading capabilities and with all this performance, the engine seems to be pretty reliable too.

In comparison, Both the GM twins, GMC Sierra 2500HD and Chevrolet Silverado 3500HD get engines with nearly similar horsepower with the GMC edging over the Chevy Silverado. As we said before, the GMC is the most powerful truck in the segment. Next in line is the Chevrolet Silverado 2500HD which puts out 445 hp and 420 lb-ft of torque. The acceleration figures and quarter-mile time of both these cars are also similar. 

The RAM 2500 HD Regular Cab Diesel gets the weakest engine which is evident from its performance figures, which makes it slower by more than a second from the rest of the competition. It hits 0-60 mph in 7.2 seconds and does a quarter-mile run in 16.4 seconds which is not adequate. Ford is a serious competitor here. Despite having the least power output, it surprises everyone with its performance figures and it completes 0-60 mph in 7.2 seconds.

Sadly, we don’t have the official fuel figures of the 2022 GMC Sierra 2500HD which makes it hard for us to evaluate the GMC in terms of fuel efficiency figures. On the downside, the fuel figures of the 2021 model are not available as well. However, the GMC comes with the largest tank of 36 gallons. As both Chevy and GMC share the same underpinnings, it shares the same fuel tank with the Chevy Silverado 2500 HD. However, in comparison with the Sierra 1500’s Fuel efficiency, the Sierra 2500 HD is expected to offer a great driving range in the city as well as the highway.

In comparison, both Chevy and GMC’s 36-gallon fuel tank helps these massive pickup trucks to attain the maximum driving range in the competition. The RAM 2500 again loses here with its smallest tank of 32 gallons. As a result, we are expecting a more or less similar driving range to the Ford F-250 due to its similar-sized tanks. The Ford F250 Supercab, on the other hand, incorporates a fuel tank of 34 gallons. All in all, truck-like these with hefty weight and bulk usually are not so good at fuel efficiency.

The interior of the base version is pretty much underwhelming. It offers some essential features and you cannot expect a lot of comfort from the cabin of the base trim. As standard, you get a 4-way manually adjustable seat with cloth fabric upholstery, a semi-automatic climate control. You also don’t get soft plastics inside the basic cabin. Everything you touch is pretty much hard plastic. However, things totally change when you opt for SLE, you are greeted with great comfort inside the cabin of SLE trim.

 It offers a lot of high comfort features and some premium materials have been curated very well throughout the cabin. Moreover, the interior has been redesigned only last year. So you will get all the latest generation creature comforts in the SLE trim. Moving on to the interior dimensions, the GMC Sierra 2500 HD has the roomiest cabin of the lot alongside the Chevy Silverado. It can seat up to 3 passengers with a generous cabin which has headroom of 43.1 inches, shoulder room of 66.1 inches, and massive legroom of 44.5 inches which makes it the most comfortable cabin in its class. The GMC again continues its winning streak in terms of cargo capacity, it turns out to be the largest cabin in the segment measuring 83.5 cubic feet.

Among the competition, the GMC Sierra 2500HD offers a cabin that comes with adequate volume for the passengers and as compared to its rivals, it easily surpasses Ford F-250 Supercab and RAM 2500 but it comes as a draw when compared to the Chevy. The RAM 2500 on the other hand comes with the smallest cargo space of 74.7 inches which is almost 10 inches smaller than both GMC Sierra 2500 HD and Chevrolet Silverado 2500HD. The Ford F-250, however, takes the sweet spot in terms of cargo space measuring 78.5 inches. Some of the primary and optional interior features are listed below:

How intuitive is the 2022 GMC Sierra 2500HD Regular Cab Diesel’s infotainment unit?

Just like its other qualities, the infotainment of GMC Sierra 2500HD is pretty impressive and intuitive at once. A 7-inch touchscreen is available as a standard that looks good but not the best in class. You can get an 8-inch screen in the SLE trim only. The user interface offers an easy learning curve and fiddling with the infotainment screen gives you a better understanding in a very short time.

The standard 2-speaker sound system with SiriusXM Radio might not be the best in its class yet it sounds clear. Moreover, the audio and call controls are available on the steering wheel so the driver does not have to lean forward toward the center console while driving. Below are some of its salient infotainment features:

• The 7-inch touchscreen infotainment display
• Simultaneous Bluetooth pairing for two devices
• Apple CarPlay and Android Auto smartphone integration

The Huge front grille looks imposing as if it wants to attack someone. The headlights look amazing with LED lights on board. It includes a sheet metal design that is squarer and has a straight-edged design cue. In fact, the 2022 GMC Sierra is at its most premium and appealing look in this iteration, with LED fog lights as well. Additionally, the new GMC Sierra sports 17-inch alloy wheels in both trims which look huge which gives the vehicle an upright stance. Moreover, it comes with a wide array of color options such as Black Raven, Red Hot, Ebony Twilight Metallic, Summit White, and so on.

 Coming to the side profile, here you can clearly see how tall and clean the lines are designed. The design elements are very minimalistic here also, where you would not find any strange shapes and creases on the doors. The bonnet is large and comes with a vent that sends more air into the engine bay. You also get the foot rails at the bottom for convenience while stepping in. 

The windows are large and are deep-tinted. On top of that, the roof lights further enhance their looks, and they are not here for aesthetics but also for the Safety of the car during bad weather. Moving on to the dimensions, it is the longest car in the segment measuring 235.5 inches, a width of 81.8 inches, and 79.9 inches tall which is also the widest as well as tallest pick truck in the segment. However, the ground clearance is slightly lesser than some rivals in its competition. On the downside, it happens to be the heaviest pickup truck in the segment weighing about 6237 pounds.

In comparison, the GMC Sierra 2500HD Regular Cab Diesel is the bulkiest weighing 6237 lbs in the competition while the Ford F-250 SuperCab is of least weight at 6112 pounds, which might be an important aspect in the performance of the car. The Ford F-250 SuperCab, on the other hand, is not too long but still manages to have decent cargo space. 

The Chevy Silverado 2500HD also has a massive structure like the GMC, they both offer exactly the same exterior proportions and dimensions and the same ground clearance too, which measures 10.2 inches above the ground which provides you extra confidence while off-roading. Whereas the ground clearance of the Ford is the smallest here measuring 8.2 inches. The RAM 2500 Regular Cab on the other hand sports the highest ground clearance of 8.5 inches. Furthermore, Some of the standout exterior features of the new GMC Sierra include:

• LED reflector with incandescent turn signals and LED signature Daytime Running Lamps
• CornerStep, rear bumper

• The LED tail and incandescent stop, turn and reverse light
• Manually adjustable trailering mirrors
• body-color door handles
• GMC MultiPro Tailgate with six functional load/access features

When it comes to the safety of the vehicle and its occupants, once again GMC Sierra 2500 HD comes up strong by having a better list of features than the other vehicles in its class and better structural integrity. The 2022 GMC Sierra 2500HD obviously has not been rated by the NHTSA and IIHS yet. 

Also, 2021 has got no ratings from these organizations. The baby version of the Sierra 1500HD scores an overall Good rating in all the crashworthiness tests except for the small overlap front passenger side where it scores Marginal. Hence, we expect a better build quality for the 2022 model year. Moreover, it comes with some advanced active and passive safety features such as:

• Four-Wheel Automated Braking System
• Hitch Guidance
