Mercedes-Benz G-Class vs Mazda CX-30

The 2025 Mercedes-Benz G-Class retained its iconic boxy design, a nod to its origins as the utilitarian "G-Wagen" from 1979. Despite continuous updates, the G-Class maintained its distinctive features, such as a flat hood, prominent corner lights, and robust doors that clacked loudly when locked or unlocked. Subtle styling updates for 2025 included a new grille and bumpers, while functional changes like a repositioned rearview camera and new A-pillar trim were introduced. The interior was opulent, with a sci-fi aesthetic featuring large round vents, ambient lighting, and metallic trim. AMG models boasted sportier steering wheels, enhancing the rugged yet luxurious feel of the G-Class.

The 2026 Mazda CX-30, available in eight trim levels, offered a premium look and feel, especially in the S Aire Edition. This edition featured blacked-out exterior trim, white artificial leather upholstery, and suede-like dashboard trim. The Aero Gray paint provided a sharp contrast with the black details, enhancing the upscale appearance. While the lower-perimeter body cladding was thick, it protected against damage. The CX-30's interior was upscale, with a snug fit for the front seats and padded areas for comfort. However, the back seat was tight for adults, and the air conditioning struggled in hot weather. Despite these drawbacks, the CX-30's overall look and feel suggested a higher price point than its actual cost.

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 with 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 nine-speed automatic transmissions with permanent 4WD. The G 550 accelerated from zero to 60 mph in 5.3 seconds, while the G 63 achieved it in 4.2 seconds. The AMG G 63 also introduced the AMG Active Ride Control suspension system, enhancing both off-road and on-road dynamics. Despite its truck-like feel, the G-Class provided a comfortable ride with low wind and tire noise.

The 2026 Mazda CX-30 came with a 2.5-liter four-cylinder engine, with higher trims offering a turbocharger. The standard engine produced 186 horsepower and 186 pound-feet of torque, while the turbocharged version delivered up to 250 hp and 320 lb-ft on premium fuel. Both engines were paired with a six-speed automatic transmission and Mazda’s i-Activ AWD system. The CX-30's fuel economy was commendable, with the naturally aspirated engine averaging 28.5 mpg in testing. The turbocharged engine offered more torque but was less fuel-efficient. The CX-30 excelled in driving enjoyment, with G-Vectoring Control Plus technology and a brake-based limited-slip differential enhancing stability and traction. Its precise steering and responsive brakes made it a rewarding SUV to drive, whether on winding roads or daily commutes.

The 2025 Mercedes-Benz G-Class, while not small, was more compact than other luxury SUVs. It offered ample headroom but limited legroom due to its tall-yet-short passenger compartment. The driving position was upright, reflecting its utilitarian origins. Cargo space was limited, with 22.6 cubic feet available with the rear seats in place. The G-Class had a towing capacity of 7,716 pounds, slightly less than some rivals. Despite its size, the G-Class was easier to maneuver and park, thanks to its short length and narrow width.

The 2026 Mazda CX-30 had some practicality issues, with small door openings making entry and exit challenging. The back seat was tight for adults, and the cargo area was small for the segment, offering 20.2 cubic feet of space. The front seats were comfortable but snug, with padded areas for comfort. The air conditioning struggled in hot weather, and rear USB charging ports were lacking. However, the CX-30 offered reasonable storage space up front, with a roomy bin, sizable cupholders, and a smartphone tray. Folding the rear seats expanded the cargo area to 45.2 cubic feet, though it remained one of the smaller measurements in the segment.

The 2025 Mercedes-Benz G-Class featured the Mercedes-Benz User Experience (MBUX) infotainment system, with standard wireless Apple CarPlay and Android Auto. It included dual 12.3-inch screens, creating a continuous display across the dashboard. The off-road menu provided useful information, and the "Transparent Hood" feature aided in navigating obstacles. Augmented reality navigation and excellent voice recognition were notable MBUX features. A Burmester 3D surround sound system was standard, with options like a dashcam and rear-seat entertainment system available.

The 2026 Mazda CX-30's Mazda Connect infotainment system offered varying screen sizes and functionality. The base S trim had an 8.8-inch display with wired Apple CarPlay and Android Auto, while higher trims featured a 10.25-inch screen with touchscreen functionality for smartphone integration. A 12-speaker Bose premium sound system was available in top trims. The system's native interface was only accessible via a console knob, which took time to get used to. Voice recognition was lacking, but Apple CarPlay and Android Auto provided better alternatives.

Standard safety features included forward-collision warning, automatic emergency braking, lane-keep assist, adaptive cruise control, and more. The Pre-Safe system prepared the vehicle for imminent crashes. New features for 2025 included route-based speed adaptation, automated lane centering, and an emergency-stop feature.
