Then, we’ll discover which vehicle comes out a winner. But don’t miss out on the chance to test-drive a 2025 QX80 at Harte INFINITI in Hartford, CT. Then, you can talk to our team about the 2025 QX80 range and take it for a spin.
The 2025 INFINITI QX80 is a spacious luxury SUV with three rows of seats and 160 cubic feet of space. Buyers can choose a luxurious seven-seat configuration for most trims. Alternatively, they can opt for the Split Bench Seat Package that brings seating up to eight. In contrast, the 2025 Mercedes-Benz G-Class can’t carry as many people. It has just two rows of seats and places for up to five occupants.
These two luxury SUVs have power-operated front seats with heating and ventilation. They can also be equipped with heated second-row seats. The QX80 offers ventilated second-row seats, heated third-row seats, and first- and second-row seats with massage capabilities on select trim levels. The 2025 G-Class doesn’t offer these for its second row.
Furthermore, the 2025 QX80 has a tri-zone automatic climate control system with air vents for all rows. Higher trims come with a feature called Biometric Cooling. This system can detect if a passenger feels warm and automatically cool them down. The 2025 G-Class doesn’t have this feature. Nor does it have a Plasmacluster air purifier, which is available for the 2025 QX80.
The 2025 QX80 and the 2025 G-Class come with high-resolution digital instrument clusters. Heads-up displays are available. Both models have standard Apple CarPlay® and Android Auto™. They also include Bluetooth® connectivity and wireless phone charging facilities. Those who enjoy music on the go will prefer the 24-speaker Klipsch premium audio system available for the 2025 QX80. The 2025 G-Class gets a Burmester speaker system option.
Despite having three rows of seats, the 2025 INFINITI QX80 has 22 cubic feet of trunk space. If you fold the third row, you’ll have 59 cubic feet at your disposal. The 2025 QX80 also has a split-folding third row for better adaptability. Then, if you need even more space, you can get 101 cubic feet with the second row folded as well. The 2025 G-Class can’t match this.
New for the 2025 QX80 has an efficient 3.5-liter twin-turbo V6. The engine is tuned for 450 horsepower and 516 lb-ft of torque. It is well-matched to a 9-speed automatic gearbox. Some trims also have paddle shifters for manual gear-changing control. Lower trims have rear-wheel drive but may be optioned with INFINITI All-Mode 4WD®. Higher trims get INFINITI All-Mode 4WD® as standard, plus Dynamic Digital adaptive air suspension. A brake-actuated limited-slip differential is also included.
Meanwhile, the 2025 G-Class G550 has a turbocharged 3.0-liter 6-cylinder engine that produces 443 horsepower and 413 lb-ft of torque. It powers all four wheels through a 9G-TRONIC 9-speed automatic gearbox and a 4MATIC all-wheel drive system.
The 2025 INFINITI QX80 comes with some helpful safety features. All trims have automatic emergency braking with forward collision prevention. They also get a rear collision prevention system that includes rear automatic braking. Buyers can also expect lane departure warnings, a driver attention alert system, and a blind-spot information system. Infiniti’s ProPILOT Assist 1.1 comes for most trims as well. This offers hands-on, semi-autonomous driving. Higher trims get ProPILOT Assist 2.1, which has the hands-off capability.
Another neat feature is the ability to detect an unresponsive driver. If the 2025 QX80 detects this condition, it can activate the hazard lights and come to a smooth stop. Buyers can also choose a 360-degree surround-view camera system with moving object detection.
The 2025 G-Class has advanced safety features, including automatic emergency braking, blind-spot monitoring, lane-keeping assist, adaptive cruise control, and a surround-view camera system. While it may not have the hands-free driving features of the QX80 (ProPILOT Assist 2.1), it does include a suite of driver-assistance technologies.
The 2025 INFINITI QX80 takes a clean sweep across our INFINITI vs Mercedes-Benz match-up. It wins every single one of our three criteria. That makes it the best luxury SUV in Hartford, CT, and one that you should definitely consider.
