2021 INFINITI QX80 Reviews SummaryYou might not expect Nissan’s luxury brand to make a hulking land yacht with globetrotting off-road capability, but that’s exactly what you get with the 2021 Infiniti QX80. The QX80 is one of the last old-school SUVs, boasting body-on-frame construction and an available four-wheel drive (4WD) system with low range. It’s based on the Nissan Armada, which in turn is a rebadged version of the overseas-market Nissan Patrol—a legendary off-roader. As a full-size luxury SUV based on a model from a mainstream brand, the QX80 follows the same formula as the Cadillac Escalade, Lexus LX 570, and Lincoln Navigator. In size, price, and prestige, it could also be considered a rival to the Land Rover Range Rover, BMW X7, and Mercedes-Benz GLS-Class, but these SUVs have more modern unibody construction. The QX80 gets some small updates for the 2021 model year, including an improved version of Infiniti’s Smart Rearview Mirror. The Canadian trim line-up includes the base Luxe and the more highly equipped ProACTIVE grade, the latter available with seven or eight seats. Our test vehicle was the Canadian equivalent of the U.S. Sensory model, the ProACTIVE 7-passenger grade. | |
2022 Mercedes-Benz GLS Reviews SummaryThe SUV that’s now known as the GLS was launched for the 2007 model year as the GL-Class, when Mercedes decided it needed a bigger, more luxurious SUV to sit above the M-Class in its lineup. The GL-Class and M-Class were rebadged the Mercedes-Benz GLS-Class and GLE-Class, respectively, in 2014 when Mercedes introduced a new naming scheme across its lineup. The current version of the GLS was introduced for the 2020 model year, and represents the model’s third generation. It’s aimed at other full-size luxury SUVs, including the BMW X7, Cadillac Escalade, Infiniti QX80, Land Rover Range Rover, Lincoln Navigator, and Lexus LX. Four models are available in Canada: the base six-cylinder GLS 450 4Matic, the GLS 580 4Matic, the AMG GLS 63 4Matic+, and the Mercedes-Maybach GLS 600 4Matic. Availability is currently limited, and specifications for the 2022 model year are not available. However, they are expected to be very close to those listed for 2021, which were used as reference for the information provided here. We tested a U.S.-specification 2022 GLS 450 for this review. | |

The 2021 INFINITI QX80 showcased a blend of Nissan Armada and Infiniti design elements, with its body-on-frame construction reminiscent of traditional SUVs. Its profile, marked by the roofline and rear window curves, mirrored the Armada, while the front fenders featured vents. The QX80's front-end styling, introduced in 2018, was distinctly Infiniti, with a grille and headlight design that provided an assertive yet not overly aggressive look. Standard LED lighting and large alloy wheels added to its luxury appeal, while the interior, though luxurious with wood trim and leather upholstery, retained a Nissan-like design, which might have disappointed those seeking exclusivity.
In contrast, the 2022 Mercedes-Benz GLS 450 offered a more understated appearance compared to its flashier competitors. The base model avoided excessive chrome and gaudy grilles, while the AMG and Maybach versions provided options for more visual drama with features like flared wheel arches and chrome accents. Inside, the GLS 450's interior was luxurious yet subdued, with leather upholstery, a panoramic roof, and ambient lighting. The digital instrument cluster and infotainment touchscreen were well-integrated, providing a high-quality feel without being overly fragile. However, some ergonomic issues, like the touchscreen's reach, were noted.














The 2021 INFINITI QX80 was powered by a 5.6-litre V8 engine producing 400 horsepower and 413 lb-ft 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, combined with independent suspension and Hydraulic Body Motion Control, provided a comfortable ride, though it exhibited some body roll in corners. Its 4WD system, with low range and a skid plate, offered off-road capability, and it boasted a towing capacity of 3,855 kilograms.
The 2022 Mercedes-Benz GLS 450 featured a 3.0-litre turbocharged inline-six engine with 362 horsepower and 369 lb-ft of torque, supplemented by the EQ Boost mild-hybrid system. This setup provided ample power, with the electric motor adding short bursts of extra torque. The GLS's air suspension offered adjustable ride height but lacked refinement, leading to excessive body motion. With a towing capacity of 3,500 kilograms, the GLS was capable but fell short of some competitors in this regard.
The 2021 INFINITI QX80 offered a seven-seat configuration with second-row captain’s chairs, or an eight-seat option with a bench seat. While passenger space was competitive, it wasn't class-leading, and cargo space was limited compared to rivals. The QX80 provided 470 litres of cargo space with all seats in place, expanding to 2,694 litres with the second and third rows folded. Standard features included power-adjustable front seats and a power liftgate, though some ergonomic issues, like inadequate thigh support, were noted.
The 2022 Mercedes-Benz GLS came standard with a seven-seat configuration, with an optional six-seat version featuring captain’s chairs. The GLS offered excellent second-row legroom, thanks to its long wheelbase, and competitive cargo space, with 355 litres available with all seats in place, expanding to 2,400 litres with the second and third rows folded. The GLS featured power-folding seats and a power tailgate, with air suspension aiding cargo loading. However, some ergonomic issues, like the touchscreen's reach, were noted.
The 2021 INFINITI QX80 featured the Infiniti InTouch dual-screen infotainment system with Apple CarPlay, Android Auto, and a 17-speaker Bose audio system. While the system offered various controls, the user interface was cumbersome, requiring trial and error to navigate. The Smart Rearview Mirror and Around View Monitor added convenience and safety.
The 2022 Mercedes-Benz GLS boasted the MBUX infotainment system with a 12.3-inch touchscreen, digital instrument cluster, and voice recognition. The system offered multiple control options, with voice recognition being the most effective. The GLS included augmented-reality navigation, though the embedded system occasionally suggested inefficient routes.
The 2021 INFINITI QX80 received a four-star overall safety rating from the NHTSA, with standard features like blind-spot monitoring, lane-departure warning, and automatic emergency braking. The ProACTIVE grade added advanced features like Backup Collision Intervention.
The 2022 Mercedes-Benz GLS included standard safety features like forward collision warning, automatic emergency braking, and blind-spot monitoring. Optional features included adaptive cruise control and advanced driver-assistance systems. Crash-test ratings were unavailable at the time of publication.
