2021 Mercedes-Benz GLS vs 2021 Honda Passport

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, evolved from the GL-Class, which debuted in 2006. Initially intended to replace the G-Class, the GLS instead found its niche among affluent families seeking a luxurious alternative to the Navigator and Escalade. The current GLS, with its softened angles and sleek design, appeared less bulky than its predecessors. Inside, it boasted a futuristic cabin dominated by a massive digital screen, emphasizing its tech-centric controls. The GLS lineup included the GLS 450, GLS 580, and the high-performance AMG GLS 63, each offering a range of luxurious features and optional packages to enhance comfort and convenience.

In contrast, the 2021 Honda Passport was essentially a two-row version of the Pilot, sharing many design elements both inside and out. The Passport's interior mirrored the Pilot's, including the somewhat awkward button shifter for the automatic transmission. Despite this, the Passport offered a spacious and high-quality cabin. Trim levels ranged from the entry-level Sport to the top-tier Elite, each adding progressively more features such as leather upholstery, power moonroof, and advanced audio systems. The Passport's straightforward trim structure meant that all features were neatly packaged without the need for additional options.

The 2021 Mercedes-Benz GLS offered a range of powerful engines. The entry-level GLS 450 featured a twin-turbocharged 3.0-liter inline-six engine producing 362 horsepower and 369 pound-feet of torque. The GLS 580 upgraded to a twin-turbocharged 4.0-liter V8 with 483 horsepower and 516 pound-feet of torque. Both models used a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel drive system. The AMG GLS 63, with its hand-crafted 4.0-liter twin-turbo V8, delivered an impressive 603 horsepower and 627 pound-feet of torque, achieving 0-60 mph in just 4.1 seconds. All engines included the EQ Boost 48-volt mild-hybrid system, adding extra power and aiding in turbocharger spool-up. The GLS 63 featured an adaptive air suspension system, multiple drive modes, and E-Active Body Control for a smooth and composed ride.

The 2021 Honda Passport came standard with a 3.5-liter V6 engine producing 280 horsepower and 262 pound-feet of torque, paired with a nine-speed automatic transmission. It offered standard front-wheel drive and optional all-wheel drive. The V6 provided strong acceleration, though the stop-start system could be abrupt. The Passport's ride balanced comfort and handling, with 8.1 inches of ground clearance and drive modes for various terrains. The AWD model could tow up to 5,000 pounds, making it suitable for light off-roading and towing needs.

The 2021 Mercedes-Benz GLS featured three rows of spacious seating, with ample headroom and legroom for first- and second-row occupants. Standard seven-passenger seating could be reduced to six with optional second-row captain's chairs. The third row, while less spacious, was still suitable for adults. The GLS offered 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 rows down. The power-folding third row and numerous storage compartments added to its practicality.

The 2021 Honda Passport provided 100.8 cubic feet of cargo space with the rear seats folded, and 50.5 cubic feet with the second row in use. An additional 2.5 cubic feet of under-floor storage added convenience. The EX-L trim and above included a power liftgate, with hands-free operation on the Touring and Elite trims. The upright seating position offered excellent visibility, and the center console featured ample storage. The rear seats provided generous headroom and legroom, with reclining and sliding capabilities for added comfort.

The 2021 Mercedes-Benz GLS came standard with the MBUX infotainment system, featuring a large touch screen and a trackpad controller. It included Apple CarPlay and Android Auto, though a USB-C cable was required. The MBUX voice-control system responded to commands like "Hey Mercedes," and the digital dash extended to the instrument panel, controlled by touch-sensitive pads on the steering wheel. This setup allowed for a customizable and tech-forward driving experience.

The 2021 Honda Passport made Android Auto and Apple CarPlay standard with its 8-inch touchscreen infotainment system. While this was a welcome addition, the system's dated graphics, confusing menu layout, and awkward volume dial detracted from the overall experience. Despite these shortcomings, the inclusion of smartphone connectivity as standard was a significant advantage over the Pilot.

The 2021 Mercedes-Benz GLS came equipped with numerous driver-assistance features, including Active Brake Assist, forward-collision avoidance, rain-sensing wipers, blind-spot monitoring, and automatic high beams. Additional safety tech included lane-keep assist, lane-change assist, adaptive cruise control, and a following-distance indicator. The GLS also featured a full array of airbags, traction control, self-tensioning seatbelts, and a tire-pressure monitoring system.

The 2021 Honda Passport offered advanced safety features such as automatic emergency braking, forward collision warning, lane departure warning, and adaptive cruise control. Optional features included blind-spot monitoring, rear cross-traffic alert, and front-and-rear parking sensors. The Passport received a five-star overall rating from the NHTSA and top scores from the IIHS, though it had "Acceptable" ratings for headlights and child-seat anchor ease of use.
