The 2026 INFINITI QX80 represents a complete, ground-up redesign, transforming the brand's flagship luxury SUV into a formidable competitor in the full-size segment. The most significant change is the replacement of the long-running V8 engine with a modern 3.5-liter twin-turbo V6, which delivers a potent 450 horsepower and 516 lb-ft of torque—a notable increase over the previous model—paired with a new 9-speed automatic transmission. Inside, the cabin is a technological sanctuary defined by dual high-definition displays, including a large infotainment screen, the luxury of available massaging second-row seats, and the introduction of a new Electronic Air Suspension for enhanced ride comfort and dynamic handling. Exterior styling is dramatically modernized with flush door handles, an illuminated front emblem, and an available SPORT trim that adds dark accents and a more aggressive visual stance, all culminating in a vehicle designed to combine imposing road presence with top-tier comfort and innovation.
