2021 Mercedes-Benz GLS vs 2021 Lexus NX

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 launched as the GL-Class in 2006, it was intended to replace the G-Class, but the latter's popularity kept it in production. The GLS, with its three rows and comfortable interior, became a family-friendly alternative to the Navigator and Escalade. The transition from "GL" to "GLS" occurred during the second generation, and the 2021 model featured softened angles and a sleek design. Inside, the GLS boasted a futuristic cabin with a massive digital screen dominating the dashboard, emphasizing its tech-reliant controls. Available in 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.

The 2021 Lexus NX retained its familial design, with sharp lines and a sculpted exterior reminiscent of the smaller UX and larger RX models. Offered in NX 300, NX 300 F Sport, and NX 300h hybrid versions, the NX 300 and 300 F Sport gasoline models were the focus of this review. The F Sport variant added sporty elements like a honeycomb grille, triple-beam LED headlights, and 18-inch wheels. Inside, the NX F Sport featured exclusive quilted NuLuxe sport seats and optional Circuit Red interior. The interior's fit and finish were excellent, typical of Lexus, though the design felt dated compared to competitors. The F Sport's G-Force meter, inspired by the Lexus LFA supercar, was more of a gimmick than a practical feature. The center stack, with its elevated climate-control buttons and rare CD player, added to the NX's unique but functional interior design.

The 2021 Mercedes-Benz GLS offered a range of powerful engines, starting with the GLS 450's twin-turbocharged 3.0-liter inline-six, producing 362 horsepower and 369 pound-feet of torque. The GLS 580 upgraded to a twin-turbocharged 4.0-liter V8, delivering 483 hp and 516 lb-ft. Both models featured a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel drive. The AMG GLS 63, with its hand-crafted 4.0-liter twin-turbo V8, generated an impressive 603 hp and 627 lb-ft of torque, achieving 0-60 mph in just 4.1 seconds. All engines included Mercedes’ EQ Boost 48-volt mild-hybrid system, adding extra power when needed. The GLS 63's adaptive air suspension and multiple drive modes provided a smooth, composed ride, even on rough roads, while maintaining agility and precision in handling.

The 2021 Lexus NX, while not designed for sportiness, offered capable performance with its turbocharged 2.0-liter four-cylinder engine, producing 235 horsepower and 258 pound-feet of torque. The standard six-speed automatic transmission was adequate, though less smooth than newer multi-speed options. The NX accelerated from 0-60 mph in around seven seconds, with the F Sport model featuring Active Sound Control to enhance engine noise. Front-wheel drive was standard, with all-wheel drive available across trims. The NX's fuel economy was decent, with the FWD model achieving 22 mpg city and 28 mpg highway. The available adaptive-suspension system, based on the LC 500 sport coupe, provided a comfortable and engaging driving experience, though the steering lacked feedback. The NX offered three drive modes—Eco, Normal, and Sport—affecting throttle response and steering assist.

The 2021 Mercedes-Benz GLS excelled in interior space, offering three rows of seating with ample headroom and legroom for first- and second-row passengers. Standard seven-passenger seating could be reduced to six with optional second-row captain's chairs. The third row, while less spacious, accommodated full-size adults comfortably. The GLS provided 17.4 cubic feet of cargo space behind the third row, expanding to 42.7 cubic feet with the third row folded, and 87.4 cubic feet with both rear rows down. The power-folding third row and numerous storage compartments added to its practicality.

The 2021 Lexus NX featured a well-styled and comfortable interior, with front seats offering ample space for adults and the second row accommodating two adults comfortably. Heated and ventilated seats were available, and the rear seats offered a 60/40 split-folding option. The NX's cargo space was limited, with 17.7 cubic feet behind the second row and 54.6 cubic feet with the seats folded, making it one of the smallest in its class. A power liftgate with kick sensor technology and power-folding rear seats were available options.

The 2021 Mercedes-Benz GLS came equipped with the MBUX infotainment system, featuring a large touch screen and a trackpad for navigation. The system included Apple CarPlay and Android Auto, though a USB-C cable was required for connection. The MBUX voice-control system responded to commands like "Find me a gas station," enhancing convenience. The digital dash extended to the instrument panel, both controlled by touch-sensitive pads on the steering wheel, offering customizable display options.

The 2021 Lexus NX's infotainment system featured an 8-inch touchscreen, with a 10.3-inch option available in the Navigation package. The system included Apple CarPlay and Android Auto, though the Lexus interface was less user-friendly. Standard features included keyless entry, dual-zone climate control, and a WiFi hotspot. The Lexus Enform Remote app allowed remote control of various vehicle functions, while the Enform Services Connect provided maintenance alerts.

The 2021 Mercedes-Benz GLS offered a comprehensive suite of driver-assistance features, including Active Brake Assist, forward-collision avoidance, blind-spot monitoring, and automatic high beams. Additional safety tech included lane-keep assist, adaptive cruise control, and a following-distance indicator. The GLS also featured a full array of airbags, traction control, and a tire-pressure monitoring system.

The 2021 Lexus NX came standard with Lexus Safety System+ 2.0, which included lane-departure warning, traffic-sign recognition, and adaptive cruise control. Blind-spot monitoring and rear cross-traffic alert were also standard. The NX received top safety ratings from the IIHS and NHTSA, with no recalls reported. Lexus provided a four-year/50,000-mile limited warranty and a six-year/70,000-mile powertrain warranty.
