Towing Mastery: The Infiniti QX80 2025 Heavy Duty Performance
There is a moment of pure confidence when you hook up a 8,000-pound boat to the 2025 Infiniti QX80, engage the trailer blind spot warning system, and realize this massive luxury SUV was engineered not just to tow, but to make towing feel effortless—transforming what used to be a white-knuckle experience into a relaxed Sunday cruise.
For years, the Infiniti QX80 has been the quiet workhorse of the luxury SUV segment. It had the muscle, the body-on-frame toughness, and the towing numbers to compete. But it was starting to show its age. The 2025 model changes everything. Under the hood sits a new 3.5-liter twin-turbo V6 producing a staggering 450 horsepower and 516 lb-ft of torque—gains of 50 hp and 103 lb-ft over the old V8 . And it pairs this newfound power with a suite of towing technologies designed to take the stress out of hauling.
Whether you’re pulling a luxury RV to the mountains, a boat to the lake, or a horse trailer to a weekend competition, the 2025 QX80 is engineered to handle it with authority. Let’s dive into the numbers, the hardware, and the smart tech that make this SUV a towing master.
TL;DR
The 2025 Infiniti QX80 delivers class-competitive towing capability with a maximum capacity of 8,500 pounds when properly equipped with an electric trailer brake controller . This performance is powered by a new 3.5-liter twin-turbo V6 producing 450 hp and 516 lb-ft of torque—more than the outgoing V8 and competitive with the Lincoln Navigator and Cadillac Escalade . New towing technologies include Trailer Blind Spot Warning (which monitors vehicles alongside your trailer), Trailer Back-Up Assist, and a Rear Zoom View camera for easy hitching .

The Heart of the Hauler: A New Twin-Turbo V6
Let’s start with the engine because this is where the 2025 QX80 makes its biggest statement. Infiniti retired the old 5.6-liter V8—a workhorse, yes, but one that was long in the tooth—and replaced it with a 3.5-liter twin-turbocharged V6 .
By the Numbers
| Specification | 2025 QX80 (Twin-Turbo V6) | 2024 QX80 (5.6L V8) | Change |
|---|---|---|---|
| Horsepower | 450 hp @ 5,600 rpm | 400 hp | +50 hp |
| Torque | 516 lb-ft @ 3,600 rpm | 413 lb-ft | +103 lb-ft |
| Towing Capacity | 8,500 lbs | 8,500 lbs | Same |
| Transmission | 9-speed automatic | 7-speed automatic | +2 gears |
The new engine is based on the twin-turbo VR30 found in the Q50 Red Sport, but it has been “upsized to account for three elegant rows of space” . The result is a massive increase in low-end torque—516 lb-ft available at just 3,600 rpm. That means the QX80 doesn’t have to work hard to get a heavy load moving. The power is there, right when you need it.
Driving Impressions
Reviewers who have driven the new QX80 are unanimous: the new engine is a major upgrade. AutoGuide notes that “the QX80 has significantly more get-up-and-go” and is “smooth and a bit of a sleeper SUV” that “can really move when merging onto expressways” . U.S. News reports that the engine provides “sufficient off-the-line torque and good midrange power, allowing the SUV to tackle most driving situations with ease” . One reviewer summed it up perfectly: “Don’t lament the loss of the V-8; acoustics are the only advantage it holds over the V-6” .
The new V6’s torque peak arrives at just 3,600 rpm and stays strong throughout the rev range, giving you effortless pulling power exactly when you need it for towing .
Towing Capacity: 8,500 Pounds of Capability
The headline number is 8,500 pounds of maximum towing capacity when the QX80 is properly equipped with an electric trailer brake controller . This puts the QX80 in the same league as its primary rivals:
| Vehicle | Max Towing Capacity |
|---|---|
| 2025 Infiniti QX80 | 8,500 lbs |
| Lincoln Navigator | 8,300 lbs |
| Cadillac Escalade | 8,200 lbs |
| Mercedes-Benz GLS | 7,700 lbs |
This capacity means the QX80 can handle:
- Boats: Most mid-sized cabin cruisers and wakeboard boats
- Campers: Many travel trailers and small fifth-wheel campers
- Horse Trailers: Two-horse trailers with living quarters
- Utility Trailers: Heavy equipment and car haulers
The QX80’s 8,500-pound towing capacity is among the best in its class, matching the numbers from competitors that cost significantly more .
The Towing Tech Toolbox
Where the 2025 QX80 truly shines is in the technology department. Infiniti has loaded this SUV with features designed specifically to make towing safer and easier.
Trailer Blind Spot Warning
This is a game-changer. Anyone who has towed a trailer knows the stress of changing lanes on the highway. You can’t see around your trailer, so you’re constantly guessing if there’s a car in the adjacent lane.
The QX80’s Trailer Blind Spot Warning system solves this problem . Using sensors and cameras, the system monitors vehicles alongside your trailer—all the way to the end of your payload. If a car is in your blind spot, you get a warning, just as you would without a trailer. It’s like having eyes on the back of your trailer.
“Tow with confidence knowing that QX80 is looking out for adjacent vehicles you can’t see—all the way back to the end of your payload” .
Trailer Back-Up Assist
Backing up a trailer is one of the most stressful maneuvers in driving. The QX80 offers Trailer Back-Up Assist, which uses stability control technology to help you put your payload precisely where you want it . While not a fully automated system like some trucks offer, it provides assistance that makes the process significantly easier.
Rear Zoom View Camera
Anyone who has tried to hitch a trailer alone knows the dance—get out, check the alignment, get back in, move an inch, get out again. The QX80’s Rear Zoom View camera eliminates this frustration . It gives you a close-up view of the hitch area on the infotainment screen, so you can line up the ball with the coupler perfectly without leaving the driver’s seat. “Even hitching up is a one-and-done affair” .
Trailer Sway Control
While not explicitly mentioned in the marketing materials, vehicles with this level of towing capability typically include trailer sway control as part of the stability system. This technology applies brakes to individual wheels and reduces engine power if it detects trailer sway, helping you maintain control in crosswinds or when being passed by large trucks.
Chassis and Suspension: Built for the Load
Towing isn’t just about power—it’s about control. The 2025 QX80 delivers with a robust chassis and advanced suspension technology.
Body-on-Frame Construction
Unlike many modern crossovers that use car-based unibody construction, the QX80 retains body-on-frame architecture . This truck-based design provides the strength and rigidity needed for serious towing. It isolates the cabin from the stresses of hauling heavy loads and provides a solid foundation for the suspension to do its work.
Electronic Air Suspension
For 2025, Infiniti introduces its first-ever Electronic Air Suspension system . This system offers multiple benefits for towing:
- Load Leveling: The system automatically maintains ride height regardless of trailer tongue weight, keeping the SUV level and headlights properly aimed.
- Lowered Loading Position: When parked, the suspension can lower by up to 2.8 inches, making it easier to hitch a trailer and load cargo .
- Highway Lowering: At speed, the suspension lowers slightly to improve aerodynamics and fuel economy .
Dynamic Digital Suspension
The QX80 also features a Dynamic Digital Suspension that continuously adjusts damping to reduce body roll and vibration . When towing, this system helps keep the SUV stable and composed, reducing the sway and bounce that can make towing uncomfortable.
The available air suspension on the Autograph trim does a “fine job of propping up the body against roll,” helping maintain composure even with a heavy trailer behind .
Braking and Control
Stopping 8,500 pounds of trailer plus the weight of the QX80 itself (over 5,800 pounds) requires serious braking power.
Brake Specifications
The QX80 comes standard with:
- 4-wheel ventilated disc brakes
- 4-wheel ABS with electronic brake force distribution
- 14-inch front brake rotors for substantial stopping power
Integrated Trailer Brake Controller
To achieve the full 8,500-pound towing capacity, the QX80 requires an electric trailer brake controller . This allows the driver to adjust trailer braking force from the cabin, ensuring that both the SUV and trailer stop together smoothly and safely.
Hill Start Assist
When launching a heavy trailer on an incline, Hill Start Assist holds the brakes momentarily after you release the pedal, giving you time to apply throttle without rolling backward .
Real-World Towing Impressions
While detailed towing reviews of the 2025 model are still emerging, early impressions of the powertrain suggest it is more than capable. One reviewer noted that the engine “generates a wave of torque that draws you away from stops like a lost flip-flop in a swell” . This low-end grunt is exactly what you need when pulling away from a stop with a heavy trailer.
Another reviewer praised the transmission, noting it’s “smooth and entirely anonymous in relaxed driving, and it’s more than quick enough when you need it to kick down for passing or merging” . For towing, this means the transmission won’t hunt for gears or deliver jarring shifts—it will simply find the right ratio and get on with the job.
