Which vehicle holds the title of the least fuel-efficient in the Infiniti lineup for the 2024 model year? It’s none other than the QX80, a robust SUV built on a body-on-frame platform derived from the Armada, showcasing a penchant for consuming fuel.
Introduced in 2010 as the QX56, sharing its 5.6-liter V8 engine with the Armada, the QX80 has long been synonymous with power and luxury.
However, its fuel economy, rated at 16 miles per gallon (14.7 liters per 100 kilometers) with 2WD, falls short of modern efficiency standards. Nevertheless, Infiniti is poised to address this with the introduction of a new powertrain for the 2025 model year.
The forthcoming iteration will feature a twin-turbocharged 3.5-liter V6 engine, known as the VR35DDT, boasting an impressive output of 450 horsepower and 515 pound-feet of torque.
Paired with a new nine-speed automatic transmission and equipped with active front grille shutters, the QX80 aims to achieve better fuel efficiency without compromising its formidable performance.
Furthermore, the 2025 QX80 boasts enhancements such as a 57% increase in lateral stiffness and a 25% increase in torsional rigidity, promising a quieter and more refined ride.
With advanced features like Electronic Air Suspension and Dynamic Digital Suspension, this SUV offers a blend of luxury and capability, making it an enticing choice for discerning buyers.
