2021 Mercedes-Benz GLS vs 2021 Lexus GX

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, was a luxurious SUV that offered a blend of practicality and opulence. Originally known as the GL-Class, it was designed to replace the G-Class but ended up appealing to a different clientele due to the G-Class's enduring popularity. The GLS featured a more refined and sleek exterior compared to its predecessors, with softened angles and lines that belied its size. Inside, the GLS boasted a futuristic cabin dominated by a massive digital screen, emphasizing its tech-forward approach. Available in three trims—GLS 450, GLS 580, and the high-performance AMG GLS 63—the GLS offered a range of standard features, including remote keyless entry, nine USB ports, and a 13-speaker Burmester sound system. Various option packages allowed for further customization, enhancing comfort and luxury.

In contrast, the 2021 Lexus GX 460 retained much of its decade-old design, with only minor updates over the years. Its styling was characterized by the prominent spindle grille and triple-beam LED headlights, giving it a distinctive and aggressive look. However, the interior of the GX felt dated, with wood trim that resembled plastic and an abundance of actual plastic materials. Despite these shortcomings, the GX offered standard semi-aniline leather and a commanding view of the road, thanks to its upright dashboard and high seating position. The GX's exterior styling remained coherent, but the interior lagged behind modern luxury SUV standards.

The 2021 Mercedes-Benz GLS offered a range of powerful engine options. The entry-level GLS 450 was equipped with a twin-turbocharged 3.0-litre inline-six engine, producing 362 horsepower and 369 lb-ft of torque. The GLS 580 4MATIC featured a twin-turbocharged 4.0-litre V8, delivering 483 hp and 516 lb-ft. Both models utilized a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel drive system. The AMG GLS 63, with its hand-crafted 4.0-litre twin-turbo V8 engine, generated an impressive 603 hp and 627 lb-ft of torque. This powerhouse could accelerate from 0 to 100 km/h in just 4.2 seconds, reaching a top speed of 280 km/h. The GLS's adaptive air suspension and multiple drive modes allowed for a smooth and agile driving experience, defying its size and weight.

In contrast, the 2021 Lexus GX 460 featured a single powertrain option: a 4.6-litre V8 engine producing 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 weight of 2,349 kg made high-speed maneuvers and braking more challenging. The body-on-frame construction contributed to a less refined ride quality compared to unibody SUVs. However, the GX excelled in off-road capability, with a Torsen centre differential, low-range gearing, and features like Crawl Control and Multi-Terrain Select. Despite its traditional SUV characteristics, the GX's off-road prowess set it apart from many modern competitors.

The 2021 Mercedes-Benz GLS offered a spacious interior with three rows of seating, accommodating up to seven passengers. The first and second rows provided ample headroom and legroom, while the third row was suitable for adults, a rarity among three-row SUVs. The GLS boasted 355 litres of cargo space behind the third row, expanding to 1,209 litres with the third row folded, and 2,400 litres with both the second and third rows down. The power-folding third row and numerous storage compartments added to its practicality.

The 2021 Lexus GX, on the other hand, had an interior that reflected its age. The upright dashboard and high centre console limited legroom, and the steering wheel's odd angle contributed to a bus-like driving position. While the GX offered excellent outward visibility, the centre-console storage and cupholders were small. The GX's three-row seating configuration provided limited space, with the third row best suited for children. Cargo space was also limited, with only 1,833 litres available with the second and third rows folded.

The 2021 Mercedes-Benz GLS featured the advanced MBUX infotainment system, with a large touchscreen and voice-control capabilities. Apple CarPlay and Android Auto were included, though a USB-C cable was required for connectivity. The digital dash extended to the instrument panel, offering customizable displays controlled by touch-sensitive pads on the steering wheel. The MBUX system's learning curve was offset by its comprehensive functionality.

In contrast, the 2021 Lexus GX was light on tech features, lacking Apple CarPlay and Android Auto compatibility. The standard infotainment system had outdated graphics and limited functionality. However, the GX offered analog controls for most functions, providing a straightforward interface. The 17-speaker Mark Levinson audio system was a highlight, but the overall tech experience fell short of modern luxury standards.

The 2021 Mercedes-Benz GLS came equipped with a comprehensive suite of driver-assistance features, including Active Brake Assist, automatic parking assist, and crosswind assist. Optional safety tech included lane-change assist, adaptive cruise control, and blind spot monitoring. The GLS also featured a full array of airbags, traction control, and a tire-pressure monitoring system.

The 2021 Lexus GX 460 included the Lexus Safety System+ as standard, offering a pre-collision system with pedestrian detection, automatic emergency braking, and adaptive cruise control. Blind-spot monitoring and rear cross-traffic alert were also standard. However, the GX lacked some advanced safety features found in other Lexus and Toyota models, such as traffic-sign recognition and Lane Tracing Assist.
