What Does the 2025 GMC Sierra 1500 Offer? We’ll Tell You!

There’s no better feeling than knowing your truck has what it takes to complete the task at hand, finish your year-long projects, or make someone’s day by lending a hand when they need a friend with a trustworthy and strong pickup. This feeling is what GMC Sierra 1500 owners experience every day, and we’re glad you’re here today because we have much to tell you about the 2025 Sierra 1500 and all of the incredible features, performance, and other benefits it offers. Let’s discuss why this truck is what you should look for here at your GMC dealer.

Price to Performance Is Great

You may be surprised to learn that the 2025 GMC Sierra 1500 costs less than the Ram 1500, Ford F-150, or Toyota Tundra. You have a recipe for success when you combine that price tag with the performance it offers. The 2025 Sierra 1500 has a standard 2.7L TurboMax turbocharged engine paired with an eight-speed automatic transmission. This engine outputs 310 hp and 430 lb-ft of torque—more horsepower and torque than the base Ram 1500 and more torque than the F-150’s standard turbocharged 2.7L V6 engine.

The 2025 Sierra 1500’s strength is its performance-to-dollar ratio. Its base engine provides maximum towing and payload capacities of 9,400 lbs and 2,240 lbs, respectively. The Ram 1500’s base powertrain only tows up to 8,110 lbs, and the F-150’s only does marginally better with a capacity of 8,400 lbs. Base Sierra 1500 models have a significantly higher payload capacity than the entry-level F-150, which only has a capacity of 1,785 lbs.

A 10-speed automatic transmission is paired with the 2025 Sierra 1500’s other three powertrains. The other powertrains include 5.3L and 6.2L EcoTec3 V8 engines and a 3.0L Duramax turbo-diesel I-6 engine. The Toyota Tundra, Ram 1500, and Ford F-150 all lack diesel-powered engines. Going with the 5.3L V8 engine provides 355 hp and 383 lb-ft of torque, and the towing capacity increases to 11,200 lbs. The 6.2L V8 engine—the strongest regular gasoline-powered option—outputs a respectable 420 hp and 460 lb-ft of torque. Its maximum towing capacity of 13,000 lbs bests anything the Toyota Tundra or Ram 1500 offers, which max out at 12,000 lbs and 11,550 lbs, respectively.

The 2025 Sierra 1500 beats most of its full-size truck competitors when equipped with the 6.2L V8 engine. However, the turbo-diesel I-6 engine adds 200 lbs of towing capacity to the mix, bringing the total to 13,200 lbs. The turbo-diesel engine punches above its weight despite its 305 hp, largely thanks to its 495 lb-ft of torque.

GMC Knows How to Give Space

We praise GMC because it makes truck beds better than most. The Sierra 1500 and its cousin—the Chevy Silverado 1500—share the distinction of best-in-class bed length and available cargo space. The 2025 Sierra 1500’s smallest bed is 5.8 feet long. That is longer than the Toyota Tundra, Ram 1500, and Ford F-150’s shortest bed sizes. You’ll have 62.9 cu.ft. of cargo space with the smallest Sierra 1500 bed—an impressive upgrade from the 53.9 cu.ft. and 52.8 cu.ft. of space you get with the Ram 1500 and F-150’s shortest options.

The pattern continues with the second available bed size. It’s a 6.6-foot bed with an impressive 71.7 cu.ft. of space. This is longer than the Ram 1500’s 6.4-foot bed and the Toyota Tundra and Ford F-150’s 6.5-foot beds. Ram’s bed has 61.5 cu.ft. of space, and the F-150 has 62.3 cu.ft., meaning GMC makes brilliant use of its size.

The largest difference comes from the longest bed sizes—the GMC Sierra 1500 shares a best-in-class 8.2-foot bed with the Silverado 1500. Ford and Toyota both have eight-foot beds that are decent by themselves, but the Ram 1500 doesn’t have anything larger than the 6.4-foot bed we discussed. Cargo space in the longest bed is also best-in-class at 89.1 cu.ft., substantially more than the 77.4 cu. ft of space in the F-150. To put this into perspective, the GMC Sierra 1500 has 15% more cargo space than the F-150 and 45% more space than the Ram 1500’s longest bed.

Who Knew Power Could Be So Comfortable?

Trucks have become increasingly powerful. They’ve also become increasingly comfortable, and the 2025 Sierra 1500 is no exception. You can work hard with this truck while enjoying a cozy and spacious cabin. The base trim—the Pro—comes with simple four-way manually adjustable driver and front-row passenger seats. However, the SLE steps up to a standard 10-way power-adjustable driver’s seat with power lumbar support, which is also optional on the Pro. A 12-way power-adjustable front-passenger seat is standard on the SLT, AT4, and Denali.

The Sierra 1500 has heated front seats on every trim but the Pro. Heated rear seats are standard on the AT4 and Denali and available on the SLT. A heated steering wheel is also standard on every trim that comes with standard heated seats. The SLT, AT4, and Denali have ventilated front seats, which are optional on the SLT and standard on the latter two trims. Keeping cool or warm is another way to stay comfortable, but that doesn’t mean your front-seat passenger agrees with your preferred temperature. You and your front-row passenger can each adjust the temperature on your side of the cabin with dual-zone automatic climate control standard on every trim but the Pro.

Your cabin’s size depends on whether you purchase a regular cab, double cab, or crew cab. Regular cabs seat up to three passengers. You’ll find 43.11 inches of headroom and 44.53 inches of legroom. A double cab gives you 43.03 inches of front headroom in exchange for a second row of seats. The crew cab has identical front-row measurements to the double cab, but second-row measurements differ. Your 2025 Sierra 1500 has 39.88 inches of second-row headroom and 35.24 inches of legroom with the double cab and a much improved 40.12 inches and 43.40 inches of second-row headroom and legroom, respectively, with the crew cab.

Google Built-In and Much More

The 2025 GMC Sierra 1500 has one of the best infotainment centers in its class. The only problem is that it’s not standard. That doesn’t mean the standard seven-inch touchscreen infotainment center is bad—far from it. We enjoy the base infotainment center in the Sierra 1500 Pro for its sleek design and popular features like Apple CarPlay and Android Auto. However, the 13.4-inch GMC Premium Infotainment System with Google built-in in the other trims is a generational leap over the base system.

Having Google built-in gives it unprecedented connectivity functions without needing your cellphone. We praise GMC for not omitting wireless Apple CarPlay and Android Auto from the premium infotainment center regardless of Google built-in. Google built-in allows third-party app downloads, Google maps, and much more to be baked directly into the operating system. However, many people prefer using software they’re familiar with—Apple fans are heavily invested in the Apple ecosystem, for example. GMC recognizes this, and we must recognize the brand in return, though Android users will feel instantly at home.

The Truck With Everything

We’d be content just calling the 2025 GMC Sierra 1500 the truck that offers you everything you could want or need from a full-size pickup. However, value is a discussion you can’t avoid when comparing the Sierra 1500 to its competitors, and it’s hard to argue the benefits of spending less money on a better truck. GMC has hit a grand slam this year, and we fully expect manufacturers like Ford, Toyota, and Ram to have a serious discussion about how they plan to compete with GMC’s flagship pickup truck going forward.
