2025 Mercedes-Benz G-Class vs 2026 Toyota Sienna

The 2025 Mercedes-Benz G-Class retained its iconic boxy design, a nod to its origins as the utilitarian "Geländewagen" from 1979. Despite subtle styling updates like a new grille and bumpers, the G-Class maintained its traditional features, including a flat hood and prominent corner lights. The vehicle's character was further emphasized by its robust doors and latches, which produced a distinctive clacking noise. Functional changes included a repositioned rearview camera and new A-pillar trim for the G 550 models, which also offered a range of wheel options. The interior was luxurious, with a sci-fi aesthetic featuring ambient lighting and metallic trim. AMG models boasted sportier steering wheels, enhancing the driving experience.

The 2026 Toyota Sienna, particularly in the Woodland Edition, offered a practical yet somewhat uninspiring design. Priced between $42,915 and $60,305, the Woodland Edition featured a green Cypress color, aligning with its outdoorsy theme. However, the vehicle's rugged appearance was limited, with only a subtle suspension lift and standard all-season tires. Inside, the Sienna's black interior felt dark and lacked the premium feel expected at its price point. The shifter and glove compartment were criticized for their flimsy feel, and the rubber floor mats appeared easily scuffed. Despite these drawbacks, the Sienna provided a smooth ride and a crossover-like driving experience, though it lacked the engaging dynamics of some competitors.

The 2025 Mercedes-Benz G-Class offered a range of powertrains, including the gasoline G 550 and AMG G 63 models. The G 550 featured a turbocharged 3.0-liter inline-six engine, delivering 443 horsepower and 413 pound-feet of torque, while the AMG G 63 retained its 4.0-liter twin-turbo V8, producing 577 hp and 627 lb-ft of torque. Both models included a mild-hybrid system and a nine-speed automatic transmission with permanent four-wheel drive. The G 550 accelerated from zero to 60 mph in 5.3 seconds, while the G 63 achieved the same in 4.2 seconds. The AMG model also introduced the AMG Active Ride Control suspension system, enhancing both off-road and on-road dynamics.

The 2026 Toyota Sienna, a hybrid minivan, combined a 2.5-liter four-cylinder engine with a nickel-metal hydride battery pack and electric motor, producing 245 horsepower. The Woodland Edition featured an e-AWD system, adding an electric motor for the rear axle. Despite its hybrid powertrain, the Sienna's performance was limited, especially in highway passing and mountain climbing. The EPA estimated 35 mpg combined for the AWD Sienna, but real-world testing showed lower figures. The Woodland Edition's off-road capabilities were minimal, with only a slight increase in ground clearance and standard all-season tires. The driving experience was described as dull, with a soft and uncommunicative feel, though the ride was smooth and stable.

The 2025 Mercedes-Benz G-Class, while not as spacious as some luxury SUVs, offered a tall passenger compartment with ample headroom but limited legroom. Its compact dimensions made it easier to maneuver and park compared to larger rivals. The G-Class provided 22.6 cubic feet of cargo space with the rear seats in place, and a towing capacity of 7,716 pounds. The vehicle's design allowed for good forward visibility, and its corner lamps helped drivers gauge the vehicle's dimensions.

The 2026 Toyota Sienna excelled in practicality, with features like a four-zone climate control system and power sliding doors. The Woodland Edition's interior, however, felt cramped due to its all-black design and small rear windows. The second-row captain's chairs offered comfort but limited third-row accessibility when fully extended. The Sienna provided 33.5 cubic feet of cargo space behind the third row, expandable to 75.2 cubic feet with the third row folded. However, the second-row seats were not removable, limiting maximum cargo volume to 101 cubic feet, less than some competitors.

The 2025 Mercedes-Benz G-Class featured the MBUX infotainment system with wireless Apple CarPlay and Android Auto. Two 12.3-inch screens served as the gauge cluster and infotainment touchscreen, creating a seamless display. The system included off-road menus, augmented reality navigation, and voice recognition. A Burmester 3D surround sound system was standard, with options like a dashcam and rear-seat entertainment system available.

The 2026 Toyota Sienna offered a 12.3-inch digital driver display and touchscreen, with standard wireless Apple CarPlay and Android Auto. The infotainment system included various connected service plans, though the display was difficult to read in daylight. Optional features included wireless charging and a JBL sound system. The voice recognition system worked well but struggled with specific commands.

The 2025 Mercedes-Benz G-Class lacked safety ratings from IIHS and NHTSA but included standard driver-assistance features like forward-collision warning, adaptive cruise control, and blind-spot monitoring. The Pre-Safe system prepared the vehicle for imminent crashes, and new features for 2025 included route-based speed adaptation and automated lane centering.

The 2026 Toyota Sienna, equipped with Toyota Safety Sense 2.0, offered features like forward-collision warning, adaptive cruise control, and lane-keep assist. The Woodland Edition included parking sensors with low-speed automatic braking. The Sienna's safety ratings were mixed, with a five-star overall rating from NHTSA but lower scores in specific tests. It did not qualify for IIHS Top Safety Pick awards.
