Infiniti QX80 2025: A Twin-Turbo V6 Replaces the V8
The 2025 Infiniti QX80 marks a massive shift for the Japanese luxury brand. After years of relying on a naturally aspirated V8 platform, Infiniti has completely redesigned its flagship SUV to compete with heavy hitters like the Cadillac Escalade and Lincoln Navigator. This overhaul centers on a new, more powerful twin-turbo V6 engine and a suite of ultra-luxury technologies that redefine the cabin experience.
The End of the V8 Era: Performance Specs
For over a decade, the QX80 relied on a 5.6-liter V8. While reliable, it fell behind competitors in terms of torque and efficiency. The 2025 model replaces this aging engine with the VR35DDTT, a 3.5-liter twin-turbocharged V6. Despite the smaller displacement, the output numbers are significantly higher.
The new powertrain delivers 450 horsepower and 516 lb-ft of torque. This represents a substantial increase of 50 horsepower and 103 lb-ft of torque over the previous V8 model. The extra torque is available lower in the rev range, which makes the massive SUV feel lighter and more responsive during city driving and highway passing.
Infiniti has also retired the old seven-speed automatic transmission. The 2025 QX80 pairs the new V6 with a 9-speed automatic transmission. This transmission offers a 40% wider gear ratio range, allowing for punchier acceleration and quieter highway cruising. Drivers can select from Standard, Eco, Sport, Snow, and Tow modes, or configure a Personal mode to tailor the throttle response and steering weight.
Towing Capacity and Utility
If you plan to haul a boat or a heavy trailer, the switch to a V6 has not compromised utility. The 2025 Infiniti QX80 maintains a robust towing capacity of 8,500 pounds. This figure applies to both rear-wheel drive and four-wheel drive configurations, keeping it competitive with the segment leaders.
Towing is managed through a suite of new suspension technologies. The QX80 now features Electronic Air Suspension and Dynamic Digital Suspension. The air suspension automatically lowers the vehicle when parked to make loading easier. More importantly, it levels the vehicle while driving to compensate for heavy payloads or trailer tongue weight.
Advanced Camera Tech for Trailering
Infiniti has integrated camera systems that specifically aid in maneuvering this large vehicle.
- Front Wide View: This system takes camera feeds and stitches them together to provide a 170-degree view around the front of the vehicle, which helps when navigating tight parking spots or corners.
- Invisible Hood View: Using exterior cameras and advanced processing, the center screen displays an image of what is directly under the vehicle’s hood. This allows you to see curbs, tracks in a car wash, or parking blocks that are usually obscured by the massive front end.
Interior Luxury: Biometric Cooling and Audio
The interior of the outgoing QX80 was often criticized for feeling dated. The 2025 model corrects this with a cabin that rivals the best in the industry. The dashboard is dominated by two 14.3-inch high-definition displays. One serves as the digital instrument cluster, while the other handles infotainment duties with Google built-in. This means Google Maps, Google Assistant, and the Play Store are native to the car.
The Klipsch Reference Premiere Audio System
Audio quality is a major selling point for the top-tier trims. The QX80 Sensory and Autograph trims feature a Klipsch Reference Premiere Audio System with 24 speakers. This system includes titanium tweeters, an 8-inch TriPower subwoofer, and Panasonic’s DJX 3D Surround sound processing.
Notably, the system includes speakers built directly into the front seat headrests. These allow for “Individual Audio,” meaning the driver can take a phone call or listen to navigation prompts through their headrest speakers without interrupting the music playing for the rest of the passengers.
Biometric Cooling Technology
Infiniti introduces a segment-first technology called Biometric Cooling. An infrared sensor mounted in the vehicle’s headliner detects when a passenger in the second row is hot. If the system senses an elevated body temperature, it automatically directs cooling air toward that specific passenger without them having to adjust any dials. This feature works rapidly to cool occupants down after entering the car on a hot day.
Exterior Design: Artistry in Motion
The design language, termed “Artistry in Motion,” gives the QX80 a cleaner and more monolithic appearance. The front grille mimics the shape of a bamboo forest, featuring active grille shutters to improve aerodynamics.
The lighting signature is particularly distinct. It uses a “digital piano key” design for the daytime running lights and the full-width rear taillight. When you approach the vehicle with the key fob, the flush door handles automatically extend, and a light path is projected onto the ground using a wing-like pattern.

- Trailer Blind Spot Warning (which accounts for the length of your trailer)
