2018 INFINITI QX80 Performance and Engine

5.6-Liter V8 Power

Under the hood sits INFINITI's legendary 5.6-liter V8 engine, producing around 400 horsepower and 413 lb-ft of torque in standard trim. This is not a timid engine — it's the kind of powerplant that makes merging onto I-94 or navigating I-75 feel effortless, even when the truck is fully loaded with passengers and cargo. Paired with a 7-speed automatic transmission with rev-matching technology, this QX80 delivers smooth, precise downshifts that feel athletic for a vehicle of this size.

Four-Wheel Drive for Michigan Winters

Equipped with 4WD, this QX80 is purpose-built for Michigan road conditions. Whether you're navigating Detroit's winter streets, heading up to northern Michigan for a weekend trip, or simply dealing with the unpredictable Great Lakes weather, this drivetrain gives you confidence year-round. The QX80's 4WD system draws from INFINITI's long history of building capable all-terrain luxury vehicles, and it pairs nicely with the platform's towing capacity of up to 8,500 pounds.

INFINITI QX80 Features and Interior

Luxury That Seats Eight

The 2018 QX80 offers seating for up to eight passengers across three rows, making it one of the most family-friendly luxury SUVs in its class. The interior is appointed with available quilted semi-aniline leather seating, real wood trim, and a dual-panel panoramic moonroof that transforms the cabin into an open, airy space. The 13-speaker Bose audio system delivers concert-quality sound, while dual zone climate control keeps every passenger comfortable regardless of the season.

Technology and Safety

The 2018 QX80 comes loaded with technology that was ahead of its time at launch. Standard and available features include a 8-inch touchscreen infotainment display, around view monitor with moving object detection, forward collision warning, lane departure warning, and blind-spot warning. Rear cross-traffic alert adds another layer of confidence when reversing in tight parking situations — something Detroit drivers know is always welcome in busy lots and urban settings.

INFINITI QX80 Reliability and Ownership

The QX80 shares its platform and engine with the Nissan Armada and Patrol, all of which have earned strong reputations for long-term durability. The 5.6-liter V8 engine in this generation has been in production for years with minimal fundamental changes — a sign that Nissan and INFINITI got it right from the start. Owners consistently report high satisfaction with this engine's longevity when oil changes are performed on schedule and maintenance is kept current.

Common items to check on a used QX80 at this mileage include the transfer case fluid, transmission fluid, and differential fluid — all of which are straightforward maintenance items.
