Mercedes-Benz G-Class vs Mazda CX-90

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. For 2025, Mercedes introduced subtle styling updates, including a new grille and bumpers, while keeping traditional design elements intact. Functional changes included repositioning the rearview camera and adding new A-pillar trim and a rear spoiler to the base G 550 models. The interior was opulent, with a sci-fi aesthetic featuring large round vents, ambient lighting, and metallic trim. The AMG models boasted sportier steering wheels, enhancing the driving experience.

The 2026 Mazda CX-90 presented a striking appearance with its short front overhang, long hood, and rear-wheel-drive proportions. The exterior design featured concave door skins that played with light and shadow, although it risked a slab-sided look. Inside, the CX-90 impressed with high-quality materials, though the wood trim in the test vehicle had an off-putting olive undertone. The digital instrumentation mimicked classic analog gauges, and the 12.3-inch infotainment display was seamlessly integrated into the dashboard. However, the center console was cluttered, with limited storage space and an unintuitive electronic shifter. The climate controls were counterintuitive, adding to the vehicle's quirks.

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 producing 443 horsepower and 413 pound-feet of torque, while the AMG G 63 retained its 4.0-liter twin-turbo V8, delivering 577 hp and 627 lb-ft of torque. Both models included a mild-hybrid system for added power at lower speeds. 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 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-90 offered three powertrains: the 3.3 Turbo, 3.3 Turbo S, and the PHEV. The 3.3 Turbo produced 280 horsepower and 332 pound-feet of torque, while the Turbo S delivered 319 hp and 369 lb-ft on regular gas, increasing to 340 hp on premium fuel. The PHEV combined a 2.5-liter four-cylinder engine with an electric motor, generating 323 hp and 369 lb-ft on premium fuel, with an electric-only range of 26 miles. All powertrains used an eight-speed automatic transmission and standard AWD. The CX-90's handling was a standout feature, with precise steering and firm suspension, though the ride communicated road nuances to passengers. The brakes struggled with heat, affecting performance during spirited driving.

The 2025 Mercedes-Benz G-Class, while not small, was more compact than other luxury SUVs, offering a tall yet short passenger compartment with ample headroom but limited legroom. The upright driving position was a nod to its utilitarian roots. Cargo space was limited, with 22.6 cubic feet behind the rear seats, and the side-hinged tailgate could complicate street parking. The G-Class had a towing capacity of 7,716 pounds, slightly less than some competitors. Despite its size, the G-Class was easier to maneuver and park, thanks to its short length and narrow width.

The 2026 Mazda CX-90 featured firm yet comfortable seats, with heated and ventilated options for the front and second-row captain’s chairs. Storage space was limited, with a shallow bin beneath the center armrest and a larger console between second-row seats. The third row was cramped, with limited legroom due to the second-row console. Cargo space was 14.9 cubic feet behind the third row, expanding to 40 cubic feet with the third row folded. The manual folding mechanism was quick, and the CX-90 accommodated a family of four's luggage for a two-week vacation. However, the total cargo space was less than some competitors.

The 2025 Mercedes-Benz G-Class featured the Mercedes-Benz User Experience (MBUX) infotainment system with standard wireless Apple CarPlay and Android Auto. Two 12.3-inch screens served as the gauge cluster and infotainment touchscreen, creating a continuous display. The off-road menu provided useful information, and the "Transparent Hood" feature aided in navigating obstacles. Augmented reality navigation and voice recognition enhanced the driving experience. A Burmester 3D surround sound system was standard, with options for a dashcam and rear-seat entertainment system.

The 2026 Mazda CX-90 came with a 10.25-inch infotainment display on the base trim, while higher trims featured a 12.3-inch screen with wireless Apple CarPlay and Android Auto. The system was controlled via buttons and knobs, with touch functionality limited to smartphone integration. Amazon Alexa compatibility was standard but required an internet connection. The native voice recognition system lacked natural-language capability, making it challenging to use. Drivers often relied on Apple CarPlay for a smoother experience.

The 2025 Mercedes-Benz G-Class had not been rated by the IIHS or NHTSA. Standard safety features included forward-collision warning, automatic emergency braking, lane-keep assist, adaptive cruise control, park assist, a 360-degree camera system, blind-spot monitoring, rear cross-traffic alert, safe exit assist, and traffic sign recognition. 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.

The 2026 Mazda CX-90 earned the highest Top Safety Pick+ award from the IIHS and a five-star overall rating from the NHTSA. Standard safety features included forward-collision warning, automatic emergency braking, blind-spot monitors, rear cross-traffic alert, safe-exit warning, lane-departure warning, lane-keep assist, and adaptive cruise control. Higher trims added active blind-spot monitors, lane-keep assist, and head-on traffic avoidance steering assist. The Premium Plus trim included front cross-traffic alert, automatic intersection braking, and a surround-view camera system. Blind-spot warnings were effectively conveyed via digital instrumentation and the head-up display.
