2021 Mercedes-Benz G-Class vs 2021 INFINITI QX80

The 2021 INFINITI QX80 showcased a blend of Nissan Armada and Infiniti design elements, maintaining a body-on-frame construction that was shared with its Nissan sibling. Its exterior featured a distinctive roofline and rear window curve, along with front fender vents. The front end, however, was distinctly Infiniti, with a grille and headlight design that aligned with other Infiniti SUVs, offering an assertive yet not overly aggressive appearance. Standard LED lighting and large wheels added to its luxury appeal, while the interior, though luxurious with wood trim and leather upholstery, retained a recognizable Nissan influence, which might have left some buyers seeking exclusivity feeling underwhelmed.

In contrast, the 2021 Mercedes-Benz G-Class, known as the G-Wagen, retained its iconic boxy design, a nod to its rugged origins. The G-Class was available in two models, the G550 and the AMG G63, both offering extensive customization options through the G Manufaktur Program. The interior was a blend of luxury and functionality, featuring a 12.3-inch widescreen infotainment system and a matching virtual instrument panel. The G-Class was a status symbol, often seen in bold custom colors and adorned with luxury enhancements, yet it remained a capable off-road machine, true to its military roots.

The 2021 INFINITI QX80 was powered by a 5.6-liter V8 engine producing 400 horsepower and 413 pound-feet of torque, paired with a seven-speed automatic transmission. While the engine was responsive, the transmission shifts were less smooth. The QX80's body-on-frame construction provided a comfortable ride, aided by independent suspension and Hydraulic Body Motion Control on Sensory models. However, it struggled with body roll in corners. The QX80 excelled in towing, with a capacity of 8,500 pounds, but its off-road capabilities were limited by its size and wheel-tire combinations.

The 2021 Mercedes-Benz G-Class, particularly the G550, featured a twin-turbocharged 4.0-liter V8 engine delivering 416 horsepower and 450 pound-feet of torque, with a nine-speed automatic transmission and permanent 4WD. The G550 was surprisingly quick, reaching 60 mph in 5.6 seconds. Its suspension system provided a supple ride with minimal body roll, and it offered impressive off-road capabilities with adjustable suspension and locking differentials. The AMG G63 variant took performance further with 577 horsepower, achieving 0-60 mph in 4.5 seconds, and added luxury touches.

The 2021 INFINITI QX80 offered a three-row seating configuration, with options for seven or eight seats. While passenger space was competitive, it wasn't class-leading, and cargo space was limited compared to rivals like the Cadillac Escalade. The interior featured power-adjustable seats, but lacked thigh support for long trips. The center console provided limited storage, and the third row lacked charging ports. Cargo capacity was 16.6 cubic feet with all seats up, expanding to 95.1 cubic feet with seats folded.

The 2021 Mercedes-Benz G-Class provided ample interior space, with a roomy front cabin and a spacious second row. Cargo capacity was 38.1 cubic feet behind the third row, expanding to 68.6 cubic feet with the second row folded. The G550 had a payload capacity of over 1,000 pounds and could tow up to 7,700 pounds. While luxurious, some features like ventilated seats required expensive packages. The spare tire was mounted externally, adding to its rugged styling.

The 2021 INFINITI QX80 featured the Infiniti InTouch dual-screen infotainment system with Apple CarPlay, Android Auto, and a 13-speaker Bose audio system. However, the user interface was cumbersome, with small screens and complex controls. The Smart Rearview Mirror and Around View Monitor added convenience, but the overall tech experience was lacking in intuitiveness.

The 2021 Mercedes-Benz G-Class boasted twin 12.3-inch HD screens for the instrument panel and infotainment, customizable for a personalized experience. The COMAND system, with Touch Control buttons on the steering wheel, offered advanced functionality. The G550 included a Burmester Surround Sound system, WiFi, and standard connectivity features, though it lacked wireless charging.

The 2021 INFINITI QX80 received a four-star overall safety rating from NHTSA, with standard features like adaptive cruise control, blind-spot monitoring, and automatic emergency braking. However, it lacked IIHS testing.

The 2021 Mercedes-Benz G-Class included a comprehensive suite of safety features, such as active brake assist, adaptive cruise control, and blind-spot monitoring. While not rated by IIHS or NHTSA, its robust construction and advanced safety systems provided confidence on the road.
