The GMC Sierra 1500 Earns Four Pickup Superlatives

Everyone remembers those heady days of late senior year. “Senior Spring” brings its fair share of distractions as checked-out teens dream of warm summer days or post-graduation plans, but few diversions are as eagerly anticipated as senior superlatives. From “Best Dressed” and “Best Smile” to “Class Clown” and everything in between, these awards can either put a little wind in your sails or have you questioning some key life choices.

If the auto industry were a high school, full-size pickups would be a pretty good stand-in for the varsity jacket crowd. These models are like V8-powered jocks, burly football linebackers who can churn through the mud and outmuscle the competition to get your team over the goal line. While student athletes try to outdo each other in the weight room, today’s trucks are locked in a similar test of strength as they vie for the towing and hauling crown.

How is the field shaping up when it comes to the superlatives that’ll be doled out to the class of 2026? We might only be a few weeks into the spring semester, but the 2026 GMC Sierra 1500 is already looking like the odds-on favorite for a couple of key trophies. From its exclusive six-function tailgate and rugged composite cargo bed to the market’s most spacious crew cab and one of the segment’s last remaining diesel engines, let’s explore a few of the superlatives that have inspired so many drivers to seek out a GMC Sierra 1500 for sale.

Only Diesel Option in the Segment

Reports of the diesel’s demise have been greatly exaggerated. While the torque-rich engine had been a pickup mainstay since the 1970s, the segment has largely moved away from the design due to a combination of factors. From lower consumer demand and increasingly strict emissions standards to high development costs and the rise of increasingly efficient turbocharged, hybrid, and all-electric options, the diesel has faced its fair share of challenges in recent decades. Plenty of diesel options still exist at the heavy-duty end of the pickup spectrum, but Ford and Ram have both dropped diesel from their half-ton models over the last five decades. Toyota never offered one to begin with, which means that the GMC Sierra and its Chevy cousin are the last two holdouts.

The Sierra 1500’s 3.0L Duramax turbo-diesel I-6 comes standard on the off-road-ready AT4 and AT4X trims, but can also be added to the SLE, Elevation, SLT, Denali, and Denali Ultimate if you’re looking for a daily driver that can produce plenty of low-end power. The six-cylinder engine leads the lineup in terms of torque with 495 lb-ft to its name, and while it also offers a respectable 305 hp, it’s the diesel’s unparalleled efficiency and towing power that really has people talking. The Duramax engine is the thriftiest design on offer for 2026, returning up to an EPA-estimated 28 MPG on the highway. Throw in 13,300 lbs of maximum towing capacity that puts the Ram 1500 (11,610 lbs) and Toyota Tundra (12,000 lbs) to shame, and it’s easy to see why the GMC Sierra has become such a popular choice for those who expect a little more from their full-size pickup.

First Six-Function Tailgate

In the competitive full-size pickup segment, even a small advantage can make a big difference in improving a model’s mass appeal. Automakers have long focused on introducing more powerful and efficient engines, off-road packages, and towing equipment that allow buyers to take full advantage of a truck’s pulling power, but some components have been historically underserved in the never-ending quest to build a better pickup. Take the humble tailgate, for example. For many years, drivers were lucky to encounter an integrated step or maybe a power-folding function. That all changed in 2019 when GMC introduced the new MultiPro tailgate.

The six-function tailgate includes not only a full-width, fold-down step, but also a built-in work surface, multiple load stops, and a two-tier loading design that turns the truck into a cargo-hauling specialist. The GMC Sierra is also more versatile than your average mullet, which is to say that it’s both business and party in the back. In addition to its bulging bag of tricks, the MultiPro tailgate can also be outfitted with the Kicker audio system. Integrated directly into the tailgate, the Kicker audio system gives the Sierra a weatherproof stereo complete with a compact amplifier, USB port, and Bluetooth connectivity that’ll let you bring the party wherever you go.

The debut of GMC’s innovative tailgate led to nothing less than a full-scale conflict in the pickup segment. Ram was the first to latch onto the trend, introducing its own multifunction tailgate on the 2019 Ram 1500. Ford was surprisingly late to the party, waiting until the debut of the refreshed 2024 F-150 to roll out its own Pro Access Tailgate, and Toyota has eschewed the upgrade altogether. While they certainly earn some credit for trying, Ram and Ford’s own multifunction designs lack the sheer versatility of the MultiPro tailgate. Instead of introducing a range of functions, cargo levels, and load stops, these offerings rely on a simple trick. They can either swing down like a traditional tailgate or swing to the side for easier access. The Ram employs a 60/40 split door, while the F-150 features a central swinging door in a 20/60/20 configuration. While this sort of flexibility can be helpful when towing larger trailers, RVs, or other equipment that might make it difficult to access the cargo bed, it’s a little underwhelming when compared to the game-changing MultiPro design.

Most Advanced Composite Cargo Bed

The MultiPro tailgate wasn’t the only notable addition when GMC introduced the fifth-generation model in 2019. The brand doubled down on its “Professional Grade” ethos with another key upgrade in the CarboPro composite bed. Originally available only on the Denali and AT4 trims, the innovative feature is now standard on the range-topping Denali Ultimate trim. The CarbonPro bed leverages carbon-fiber-reinforced plastic (CFRP) to create a lighter, larger, and tougher bed that’s ready to handle any load. The CFRP bed weighs about 25% less than a typical steel design, allowing the Sierra to shed 60 lbs compared to previous models. The CarbonPro bed’s unique grained surface provides plenty of traction and eliminates the need for an aftermarket bedliner, and even includes indentations designed to accommodate dirt and street bikes, as well as plenty of tie-downs that can be used to secure everything from powersports and landscaping equipment to bulky materials and appliances.

While these are some major selling points, it’s the material’s corrosion-resistant qualities that really make the Sierra such a solid buy. Rust and corrosion are the bane of any road-faring vehicle, and while the nicks, dents, and subtle slices that come with heavy-duty use can often expose a cargo bed to corrosion, the Sierra’s available composite surface is able to take its fair share of abuse while keeping rust from taking hold. The CFRP surface also improves the bed’s capacity by about a cubic foot and further solidifies the Sierra as a leader in the full-size segment. The truck offers some of the best cargo capacity in its class, with spacious short- and standard-bed options. When equipped with the 5.8-foot short bed, the 2026 Sierra offers 62.9 cu.ft. of cargo space, compared with 52.8 cu.ft. in the short-bed F-150 and 53.9 cu.ft. in the short-bed Ram 1500. The story is the same when it comes to the standard beds, with the Sierra’s 6.6-foot bed delivering 71.7 cu.ft. to outshine Ford’s (62.3 cu.ft.) and Ram’s (61.3 cu.ft.) offerings by a clear margin.

Most Spacious Crew Cab

Today’s pickups have come a long way from their blue-collar roots, and now represent one of the most versatile segments on the market. While these full-size models haven’t lost their industrious edge or raw towing ability, new trims, designs, and optional equipment packages offer much greater flexibility. This is especially true for drivers who are seeking a spacious ride that offers plenty of room for the whole family. When equipped with the Regular Cab, the 2026 Sierra can comfortably accommodate three passengers, but the Double Cab and Crew Cab up the ante with seating for up to six. While the Double Cab is the smaller of the two-row options, the Crew Cab elevates the Sierra’s interior, offering a roomy ride with the capacity of a midsize SUV and the added utility only a pickup can provide.

Every major truck brand offers some sort of six-passenger cab, but the Sierra sets itself apart with the most generous dimensions of the bunch. Front-row passengers will enjoy best-in-class headroom and legroom every time they climb into the Crew Cab, which can make a big difference when it comes to ensuring long-term comfort on extended road trips or a relaxing commute after a long day on the job. The front row offers 43.0 inches of front headroom, which easily outpaces the Ford F-150, Ram 1500, and Toyota Tundra at 40.8, 40.9, and 41 inches, respectively. The same holds true for the Sierra’s first-row legroom, which measures in at 44.5 inches compared to 43.9 inches in the F-150, 41.2 inches in the Tundra, and just 40.9 inches for the Ram 1500.

The Results Are In

We’ve touched on a few of the highlights, but there are plenty more surprising superlatives to discover when you visit your local GMC dealer. The truck’s 2.7L turbocharged base engine rules the roost when it comes to torque, posting a 430 lb-ft torque figure that no other full-size base engine can match. Performance potential aside, it’s the Sierra’s premium design that really distinguishes the truck from the rest of the pickup pack. The Sierra 1500 isn’t afraid to put in a little hard work and can easily tow and haul with the best of them. However, it’s GMC’s commitment to providing a high-end pickup experience that has allowed the pickup to earn such a loyal following in the hotly contested class. The Sierra’s roomy Crew Cab speaks to this luxury focus, as does the convenience of the CarbonPro bed and MultiPro tailgate. Throw in cutting-edge comfort, convenience, and infotainment tech like a head-up display, 12-speaker Bose premium audio, an adaptive suspension, ventilated front seats, and GM’s critically acclaimed SuperCruise hands-free driving tech, and there’s only one superlative that can possibly be used to sum up the 2026 GMC Sierra 1500: Most Likely To Succeed.
