Performance Comparison: GMC vs. Ram

When it comes to power, performance, and off-road capabilities, both brands have made their mark. The 2025 models from both GM and Ram offer outstanding features that appeal to those who demand both strength and luxury in their trucks. Let’s take a closer look at how the 2025 GMC Sierra 1500 AT4X and the Ram 1500 RHO stack up in key performance areas.

Powertrain and Engine Options

The GMC Sierra 1500 AT4X offers impressive power right from the start. Its engine lineup includes a 6.2-liter V8 engine, delivering strong performance with 420 horsepower. This truck also boasts an optional 3.0-liter Duramax turbo-diesel engine, ideal for drivers looking for torque-heavy towing capabilities. Both engine choices make the AT4X a powerful contender for anyone who needs muscle behind the wheel.

In comparison, the Ram 1500 RHO features a 5.7-liter HEMI V8 engine that generates 395 horsepower. While it offers excellent power and acceleration, the Sierra’s 6.2-liter engine pulls ahead in sheer strength. The RHO also offers an optional 3.0-liter EcoDiesel V6 engine for those interested in better fuel efficiency without sacrificing power.

Off-Road Performance

Both trucks are designed to tackle off-road challenges with ease, but the Sierra 1500 AT4X takes it up a notch with its standard Multimatic DSSV dampers. This technology improves suspension performance, providing superior control and comfort on rough terrain. Add in its advanced four-wheel drive system and locking rear differential, and the AT4X is built to dominate the most demanding trails.

The Ram 1500 RHO, on the other hand, comes equipped with an excellent off-road suspension system as well, including upgraded shock absorbers. It has a solid rear axle, which makes it a tough contender for off-road tasks, but it lacks the sophisticated damper technology found in the Sierra.

Towing and Payload Capacity

For those who need to haul heavy loads, the GMC Sierra 1500 AT4X takes the lead with a towing capacity of up to 9,300 pounds when properly equipped. It also features an impressive payload capacity, allowing you to carry significant weight in the truck bed without compromising stability or performance.

The Ram 1500 RHO offers a respectable towing capacity of 8,000 pounds. While it’s no slouch, it falls short of the Sierra’s towing capabilities, especially when hauling larger loads like boats or trailers.

Fuel Efficiency

When it comes to fuel efficiency, both trucks offer competitive options. The Sierra 1500 AT4X, with its turbo-diesel engine, provides better fuel economy for long hauls and extended trips. Its efficient engine means fewer stops at the pump, making it ideal for those who travel long distances regularly.

On the other hand, the Ram 1500 RHO’s gasoline engines are solid performers but tend to consume more fuel compared to the Sierra’s diesel engine. However, with its HEMI V8, the RHO delivers a satisfying balance between performance and fuel efficiency for those looking for a truck that’s powerful but not overly thirsty.

Off-Road Capabilities and Suspension: Conquering Tough Terrain

When it comes to off-road driving, both the 2025 GMC Sierra 1500 AT4X and the Ram 1500 RHO are ready to tackle rough trails. However, each truck brings unique features to the table, making them stand out in different ways. Let’s dive into how these two trucks perform on tough terrain and what sets them apart.

Suspension Systems: The Backbone of Off-Roading

Off-road vehicles rely heavily on their suspension systems to provide smooth rides on rocky, uneven, and bumpy paths. Here’s how the Sierra 1500 AT4X and the Ram 1500 RHO compare:

• GMC Sierra 1500 AT4X: The AT4X is equipped with Multimatic DSSV dampers. This suspension system provides superior shock absorption and stability, even on the roughest trails. It’s designed to keep the ride smooth and controlled, no matter how bumpy the terrain gets. The system’s three-way adjustable dampers let the truck adapt to various off-road conditions.
• Ram 1500 RHO: The RHO comes with upgraded Bilstein shock absorbers. While these are great for off-roading, they don’t offer the same level of refinement as the Sierra’s DSSV dampers. The Bilstein shocks still provide a smooth ride, but the Sierra’s suspension system takes off-roading to a new level with its cutting-edge technology.

Ground Clearance: Overcoming Obstacles

Both trucks have impressive ground clearance, which is critical when climbing over rocks, logs, and other obstacles on off-road trails. Here’s a quick look at what each offers:

• Sierra 1500 AT4X: With an impressive ground clearance of 10.5 inches, the AT4X allows you to clear most obstacles without scraping the undercarriage. This height is perfect for navigating over rocks, logs, and uneven terrain.
• Ram 1500 RHO: The RHO offers a respectable ground clearance of 10.1 inches. While it’s slightly lower than the AT4X, it’s still more than capable of handling most off-road challenges. However, for more extreme off-roading, the AT4X provides just a bit more edge.

Four-Wheel Drive Systems: Grip and Control

Having a reliable four-wheel drive system is essential when venturing off-road. Both trucks offer advanced systems, but they differ in how they manage power delivery and traction.

• Sierra 1500 AT4X: The AT4X comes with an advanced four-wheel drive system that includes a locking rear differential. This system ensures maximum traction, whether you’re climbing steep hills or powering through mud and sand. Its system gives you the confidence to take on the toughest trails without hesitation.
• Ram 1500 RHO: The RHO also features a four-wheel drive system designed for off-roading. While it doesn’t include a locking rear differential as standard, it still provides solid traction and performance. The RHO’s system is capable of handling most off-road conditions, but it may not offer the same level of control as the AT4X in extreme situations.

Off-Road Features: The Extra Touch

Both trucks offer special features to enhance off-road performance. Here’s a breakdown of what each brings to the table:

• Sierra 1500 AT4X:
  • Underbody protection: The AT4X comes with heavy-duty skid plates to protect critical components like the oil pan and transmission.
  • Hill descent control: This feature helps maintain a safe speed while going downhill on steep, slippery terrain.
• Ram 1500 RHO:
  • Skid plates: The RHO includes skid plates, but they are not as extensive as the ones on the AT4X.
  • Hill start assist: This feature helps prevent rolling backward when starting on an incline, making it easier to handle steep terrain.

Which Truck Wins for Passenger Comfort?

When you’re off-roading, it’s not just about the truck’s power or capability. Passenger comfort matters too, especially for long trips. Both the 2025 GMC Sierra 1500 AT4X and the Ram 1500 RHO offer impressive interiors, but each brings something unique to the table. Let’s explore how these two trucks compare when it comes to comfort and interior features.

Seat Comfort and Materials

Whether you’re driving through the city or heading off the beaten path, you’ll want to be comfortable. Here’s how the seats in each truck measure up:

• GMC Sierra 1500 AT4X: The AT4X is built with premium leather seating. The front seats are heated and ventilated, offering comfort in all climates. The cabin is spacious, with plenty of room for both the driver and passengers. The seats are also designed for support during long drives, so you won’t feel fatigued after a day on the trail.
• Ram 1500 RHO: The RHO also offers high-quality seating. The seats are covered in leather, and you can opt for heated and ventilated options as well. The front seats are designed to provide comfort, but some might find the AT4X seats to be a bit more plush. The RHO’s cabin is spacious, though it feels slightly more utilitarian than the Sierra’s.

Technology and Infotainment

Both trucks are packed with the latest technology to keep you entertained and informed, but they have different approaches.

• Sierra 1500 AT4X: The AT4X is equipped with an intuitive 13.4-inch touchscreen. This large display makes it easy to control navigation, music, and other features. The Sierra also offers wireless Apple CarPlay and Android Auto, so you can connect your phone without fuss. The sound system is premium, with an optional Bose setup for a richer listening experience.
• Ram 1500 RHO: The RHO features a 12-inch touchscreen, which is also easy to use and responsive. It offers Apple CarPlay and Android Auto integration, but the screen is slightly smaller than the AT4X’s. The sound system is good, but not quite on the same level as the Sierra’s premium Bose setup.

Cabin Space: Room to Stretch

Space inside a truck matters, especially if you have a family or frequently carry passengers. Let’s compare how both trucks measure up:

• GMC Sierra 1500 AT4X: The Sierra offers generous legroom for both the front and rear seats. It’s built to comfortably fit taller individuals in both rows. The truck also offers ample headroom, so even taller passengers won’t feel cramped. Plus, the rear seats fold up to provide additional storage space when needed.
• Ram 1500 RHO: The RHO is also spacious, but it doesn’t quite match the Sierra in terms of rear-seat comfort. While the front seats are roomy, the rear seats are a bit tighter, especially for taller passengers. The rear seats do fold up, providing extra storage, but the Sierra offers a bit more flexibility overall.

Climate Control: Stay Comfortable No Matter the Weather

The weather can change quickly when you’re out on an adventure. Both trucks offer climate control features, but let’s see how they differ:

• Sierra 1500 AT4X: The AT4X comes with dual-zone automatic climate control, allowing the driver and front passenger to set their own preferred temperatures. This feature is perfect for keeping everyone comfortable during long drives. The heated and ventilated seats further enhance comfort in both hot and cold climates.
• Ram 1500 RHO: The RHO also offers dual-zone climate control, but it doesn’t have as many customizable options as the AT4X. While the seats are heated and ventilated, they don’t match the AT4X’s advanced climate control features.

Safety Features and Driver Assistance Systems

When it comes to driving off-road or cruising on highways, safety is key. Both the 2025 GMC Sierra 1500 AT4X and the Ram 1500 RHO come packed with advanced safety features, but how do they compare? Let’s take a closer look at the driver assistance systems that each truck offers.

GMC Sierra 1500 AT4X Safety Features

The Sierra 1500 AT4X is designed to keep you and your passengers safe in a variety of driving conditions. Here are some of its key safety features:

• Forward Collision Alert: This system warns you if a collision is imminent, giving you time to react.
• Automatic Emergency Braking: In case you don’t respond to the collision alert in time, this feature automatically applies the brakes to prevent or reduce the severity of a crash.
• Lane Departure Warning: The Sierra alerts you if you unintentionally drift out of your lane, keeping you on track.
• Rear Cross Traffic Alert: When reversing, this system warns you of any vehicles or objects approaching from the side.
• Surround Vision Camera System: This offers a bird’s-eye view of your truck’s surroundings, making it easier to navigate tight spaces and obstacles.

The Sierra 1500 AT4X also comes standard with OnStar Safety & Security, which includes emergency services and a network of support to help you when needed.

Ram 1500 RHO Safety Features

The Ram 1500 RHO also offers a solid set of safety features. Let’s see how it compares to the Sierra:

• Adaptive Cruise Control: This system maintains a safe distance from the vehicle ahead by automatically adjusting speed.
• Blind Spot Monitoring: The RHO alerts you if there’s a vehicle in your blind spot, preventing dangerous lane changes.
• ParkSense® Rear Park Assist: When backing up, this system detects objects in your path and alerts you to avoid collisions.
• Forward Collision Warning: Like the Sierra, the RHO has a system to warn you about potential front-end crashes.
• Lane Keep Assist: If the system detects unintended lane departure, it gently steers you back into your lane.

While the Ram 1500 RHO has great safety features, it doesn’t offer the same level of comprehensive protection as the Sierra.

Fuel Economy and Range: More Miles Between Stops

When it comes to choosing an off-road truck, fuel economy and range are key factors to consider. Whether you’re heading out on a weekend adventure or using your truck for daily tasks, you want to spend more time driving and less time stopping at the pump.
