2022 Mercedes-Benz GLS vs 2021 Lexus GX

The 2021 Lexus GX retained its rugged and aggressive exterior styling, a testament to its decade-long presence in the market. Despite its age, the GX's design remained coherent, with the massive spindle grille and triple-beam LED headlights adding a distinctive touch. However, the interior did not match the modern luxury SUV standards, with wood trim that felt like plastic and an abundance of actual plastic materials. The semi-aniline leather was a standard feature, but the overall interior quality lagged behind its competitors.

In contrast, the 2022 Mercedes-Benz GLS offered a more subtle and refined exterior, especially in its base GLS 450 form. The AMG GLS 63 and Maybach versions provided options for those seeking more visual drama, with features like flared wheel arches and chrome accents. Inside, the GLS boasted a luxurious feel with leather upholstery, a panoramic roof, and ambient lighting. The digital instrument cluster and infotainment touchscreen were well-integrated, enhancing the overall interior experience. However, some ergonomic issues, like the touchscreen's reach, were noted.

The 2021 Lexus GX was powered by a 4.6-litre V8 engine, delivering 301 horsepower and 329 lb-ft of torque, paired with a six-speed automatic transmission. While the V8 provided ample power for initial acceleration, the GX's hefty weight of 2,349 kilograms made high-speed maneuvers challenging. The body-on-frame construction resulted in a less refined ride quality, with noticeable body roll and low grip in corners. However, the GX excelled in off-road capabilities, featuring a Torsen centre differential, standard 4WD with a low range, and various off-road modes. It offered a towing capacity of 2,948 kilograms, though it was outmatched by some competitors.

The 2022 Mercedes-Benz GLS 450 featured a 3.0-litre turbocharged inline-six engine, producing 362 horsepower and 369 lb-ft of torque, complemented by the EQ Boost mild-hybrid system. This setup provided smooth and sufficient power, with the electric motor adding 21 hp and 184 lb-ft of torque in short bursts. The GLS's air suspension offered a comfortable ride, but body control was lacking, leading to excessive motion over bumps and in corners. The GLS 450 had a towing capacity of 3,500 kilograms, slightly less than some rivals but still adequate for most needs.

The 2021 Lexus GX's interior ergonomics reflected its age, with limited legroom due to the upright dashboard and high centre console. The steering wheel's odd angle and tall seating position contributed to a bus-like driving feel. Visibility was generally good, but forward visibility was hindered by the tall hood. The GX offered three rows of seating, but the third row was cramped and difficult to access. Cargo space was limited, with only 1,833 litres available with the second and third rows folded, and virtually no space with the third row in use.

The 2022 Mercedes-Benz GLS provided a more spacious and versatile interior, with a standard seven-seat configuration and an optional six-seat version with captain's chairs. The second-row seats could slide and fold for easier third-row access, and the long wheelbase ensured ample legroom. Cargo space was generous, with 355 litres available with all seats in place and up to 2,400 litres with the second and third rows folded. The GLS's air suspension facilitated loading and unloading, and power-folding seats added convenience.

The 2021 Lexus GX was light on tech features, lacking Apple CarPlay and Android Auto compatibility. The standard infotainment system was outdated, with graphics reminiscent of the 1990s. However, Lexus provided analog controls for most functions, offering a straightforward interface. The 17-speaker Mark Levinson audio system was a highlight, but the overall tech offering was limited for a luxury SUV.

The 2022 Mercedes-Benz GLS featured the advanced MBUX infotainment system, with a 12.3-inch touchscreen, digital instrument cluster, and Apple CarPlay/Android Auto connectivity. The system offered multiple control options, including voice recognition, which was particularly effective. The graphics were sharp, and the augmented-reality navigation added a modern touch. However, the touchpad controller was cumbersome, and the navigation system occasionally suggested inefficient routes.

The 2021 Lexus GX came with the Lexus Safety System+ as standard, including features like a pre-collision system, automatic emergency braking, and adaptive cruise control. However, it lacked some advanced safety features found in other Lexus and Toyota models, such as traffic-sign recognition and Lane Tracing Assist. Crash-test ratings from NHTSA and IIHS were not available.

The 2022 Mercedes-Benz GLS offered a comprehensive suite of standard safety features, including forward collision warning, automatic emergency braking, and blind-spot monitoring. Additional features like Crosswind Assist and Pre Safe enhanced safety, but some advanced driver-assistance features were optional. These included adaptive cruise control and Active Steering Assist. Like the GX, crash-test ratings were unavailable at the time of publication.
