2021 Mercedes-Benz GLS vs 2021 Lexus NX Hybrid

The 2021 Mercedes-Benz GLS, a continuation of its third generation, was a luxurious SUV that offered a blend of practicality and elegance. Originally introduced as the GL-Class, it evolved into the GLS, appealing to families seeking comfort and style. Its design featured softened angles and a futuristic cabin dominated by a massive digital screen, emphasizing its tech-forward approach. The GLS lineup included the GLS 450, GLS 580, and the performance-oriented AMG GLS 63, each offering a range of luxurious features and options.

In contrast, the 2021 Lexus NX Hybrid presented a sharp, streamlined profile with a distinctive scowling face. Despite its sporty appearance, the NX Hybrid retained the same platform as the older Toyota RAV4, making it feel somewhat dated. The F Sport Black Line edition added unique styling elements like a larger mesh grille and dark-finish wheels. Inside, the NX Hybrid's design was familiar yet functional, with a stepped center console and sport-inspired features. However, the material quality felt more mainstream than luxury.

The 2021 Mercedes-Benz GLS offered a range of powerful engines. The GLS 450 featured a 3.0-liter inline-six engine with 362 horsepower, while the GLS 580 boasted a 4.0-liter V8 producing 483 hp. The AMG GLS 63, with its hand-crafted 4.0-liter twin-turbo V8, delivered an impressive 603 hp. All models included the EQ Boost mild-hybrid system, enhancing performance and efficiency. The AMG GLS 63 could accelerate from zero to 60 mph in just 4.1 seconds, showcasing remarkable agility for its size. Its adaptive air suspension and multiple drive modes provided a dynamic driving experience.

The 2021 Lexus NX Hybrid, powered by a 2.5-liter four-cylinder engine and an electric motor, produced a combined 194 horsepower. While its F Sport styling suggested sportiness, the NX Hybrid prioritized fuel efficiency over performance, with a 0-60 mph time of 9.1 seconds. The sport-tuned suspension improved handling, but the steering lacked responsiveness. Drive modes like Eco and Sport offered minimal impact on performance, emphasizing the NX Hybrid's focus on comfort and efficiency.

The Mercedes-Benz GLS excelled in interior space, offering three rows of seating with ample headroom and legroom. It provided 17.4 cubic feet of cargo space behind the third row, expanding to 87.4 cubic feet with seats folded. The GLS featured numerous storage compartments and a power-folding third row, enhancing practicality.

The Lexus NX Hybrid, however, struggled with interior space. It had limited headroom and rear legroom, making the rear seats feel cramped. Cargo space was also limited, with 16.8 cubic feet behind the rear seats and 53.7 cubic feet with them folded. Despite these limitations, the NX Hybrid offered comfortable front seats with power adjustments and available heated and ventilated options.

The GLS featured the advanced MBUX infotainment system with a large touchscreen and voice control, offering seamless integration with Apple CarPlay and Android Auto. The digital dash extended to the instrument panel, controlled by touch-sensitive pads on the steering wheel, providing a tech-savvy experience.

In contrast, the Lexus NX Hybrid's infotainment system was a weak point. It relied on a touchpad interface, which was challenging to use while driving. Although it included Apple CarPlay and Android Auto, the system felt outdated, with graphics reminiscent of the 1990s. The base audio system lacked the quality expected from a luxury brand.

The GLS came equipped with a comprehensive suite of driver-assistance features, including Active Brake Assist, blind-spot monitoring, and a surround-view camera system. Optional safety tech included adaptive cruise control and lane-keep assist, enhancing its safety credentials.

The Lexus NX Hybrid earned a “Top Safety Pick+” from the IIHS and a five-star rating from the NHTSA. It included the Lexus Safety System+ 2.0, offering features like forward-collision warning and adaptive cruise control. However, it lacked a 360-degree camera system, which was available in many competitors.
