If you’re checking out full-size pickups, you may find yourself torn between the 2025 GMC Sierra 1500 and the 2025 RAM 1500. Both trucks are strong and stylish, but if you take a closer look, you’ll spot some important differences.
The Sierra has a sharp, chiseled look and a trim lineup that delivers a luxury experience without the luxury price tag. Meanwhile, the RAM 1500 is dialing up the comfort and tech this year. And even though the classic V-8 engine is bowing out, it’s being replaced with more efficient powertrains.
The bottom line is that both trucks deliver. But if you’re into bold design, proven capability, and affordable high-end trims, the Sierra 1500 may be the truck for you. If you still need convincing, let’s break it down a little more for you.
RAM 1500 vs. GMC Sierra 1500: Design and Exterior Features
The 2025 GMC Sierra 1500 is here to make a statement. It features a unique signature grille on each trim and has just enough chrome and LED detailing to stand out while not being too flashy. Its angular, no-nonsense body shape turns heads in the city and fits right in on a job site. You can customize your Sierra 1500 to fit your lifestyle — choose from Regular, Double, or Crew cabs and long, standard, or short beds.
Over on the RAM 1500, things are sleeker this year. The grille has been cleaned up, the headlights are smarter, and the RAM badge now sits higher for more presence. Crew Cab options come with either a 67- or 76-inch bed, and there are clever extras, such as lockable side compartments and a deployable bed step.
GMC Sierra vs. RAM 1500: Powertrain and Performance
Both the 2025 GMC Sierra 1500 and RAM 1500 bring plenty of power, but they go about it in different ways.
Engines and Performance Specs
The Sierra lineup starts with the TurboMax 2.7-liter I-4 that generates 310 horsepower and 430 lb-ft of torque. However, most drivers gravitate toward the classic 355-horsepower 5.3-liter V-8 or upgrade to the 400-horsepower 6.2-liter V-8. But if torque is what you need, there’s the 3.0-liter turbodiesel, which cranks out 495 lb-ft of torque.
RAM’s 2025 models feature a bold new engine lineup. Replacing the V-8 is a twin-turbo I-6, offering smooth operation and impressive power. This engine comes in two versions. The standard version generates 420 horsepower and 469 lb-ft of torque, while the High Output trim boasts a thrilling 540 horsepower and 521 lb-ft of torque. The reliable 3.6-liter V-6 engine with 305 horsepower and mild-hybrid technology remains as the base engine.
Transmission and Drivetrain Dynamics
The Sierra’s TurboMax engine pairs with an eight-speed automatic transmission, while the V-8s and diesel go with a 10-speed automatic. Rear-wheel drive is standard, but most trims offer four-wheel drive, while the 6.2-liter V-8 comes exclusively with it.
In comparison, the RAM 1500 features an eight-speed automatic across the board, no matter which engine you choose. Rear-wheel drive is standard, but four-wheel drive is available for certain trims.
Fuel Economy
If you want mileage over muscle, Sierra’s diesel delivers the best numbers, up to 23 mpg city and 29 mpg highway. Go with the four-wheel-drive 6.2-liter V-8, and you’re looking at 15 mpg city and 20 mpg highway.
RAM’s new turbo I-6 with rear-wheel drive is a decent middle ground, rated at 18 mpg city and 25 mpg highway, while the four-wheel-drive High Output offers 15 mpg city and 21 mpg highway. However, the base V-6 remains the most efficient of the bunch, topping out at 20 mpg city and 25 mpg highway.
GMC Sierra 1500 vs. Dodge RAM 1500: Interior Comfort and Technology
When you look inside the 2025 Sierra 1500, it’s clear that the cabin was made with you in mind. The controls are right where you want them, the materials are premium, and the higher you go, the more it feels like you’re sitting in a luxury SUV. At the top of the lineup, the Denali Ultimate is full luxury, with massaging 16-way power front seats, open-pore wood, and plush leather surfaces.
Tech-wise, the Sierra delivers. The 13.4-inch touch screen pairs with a 12.3-inch digital cluster starting on the SLE. Google-powered voice commands let you keep your eyes on the road, and wireless Apple CarPlay and Android Auto look sharp on the big screen. Even the seat buzzes you with alerts when backing up. Also, Super Cruise is available on Denali trims.
The RAM 1500 doesn’t back down, either. It has loads of space, and if you go for the new Tungsten trim, you’ll enjoy 24-way power seats with massage, real wood, and even a 23-speaker Klipsch sound system. The RAM 1500 offers either a 12-inch or 14.5-inch infotainment screen, but the interface can be laggy and hard to navigate. Some features are screen-only, too, which can get frustrating when the software drags. That being said, RAM rolled out its own hands-free driving system, which works well.
Dodge RAM 1500 vs. GMC Sierra 1500: Pricing and Car Trim Level Comparison
Pricing for the new Sierra 1500 kicks off at $38,300 and stretches up to $84,200 if you go all-in. There are eight trims total and plenty of customization in the cab and bed options. If you want a solid midtier choice, consider the Elevation trim. It looks sharp, isn’t overly priced, and offers a solid balance of comfort and utility.
The 2025 RAM 1500 starts slightly higher at $40,275 and tops out at $87,320. The new ultra-lux Tungsten trim brings next-level comfort, but it’ll cost you. The Rebel and Laramie trims offer more value, especially if you want off-road gear or something a little more refined.
