2025 Mercedes-Benz G-Class vs 2026 BMW X3

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. The G-Class offered a range of wheel options and an extensive Manufaktur program for personalized exterior and interior combinations. Inside, the G-Class boasted a luxurious yet rugged aesthetic, with features like large round vents, ambient lighting, and metallic trim. The dashboard prominently displayed switches for differential locks, and AMG models featured a sportier steering wheel.

The 2026 BMW X3, particularly the X3 M50 model, was priced from $67,850 and featured numerous upgrades, including a striking Frozen Deep Grey paint job. The interior, while equipped with Merino leather and ventilated seats, was criticized for its austere design, which some found unworthy of its nearly $80,000 price tag. The X3's design was described as "monolithic," with an illuminated grille surround that divided opinions. The cabin's touch-sensing controls and lack of surface liners detracted from its overall appeal. However, the X3 offered excellent nighttime lighting and a panoramic glass sunroof. Cargo space was generous, with a power liftgate revealing 31.5 cubic feet of storage, expandable to 67.1 cubic feet with the rear seats folded. Despite some interior shortcomings, the X3 provided a comfortable and practical driving experience.

The 2025 Mercedes-Benz G-Class lineup included the gasoline G 550 and AMG G 63 models, alongside the all-electric G 580 variant. 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 incorporated a mild-hybrid system, adding 20 hp and 148 lb-ft 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 2026 BMW X3 M50 was powered by a turbocharged 3.0-liter inline six-cylinder engine, generating 393 horsepower and 428 pound-feet of torque. This engine provided exhilarating acceleration, reaching 60 mph in 4.4 seconds. The M50 featured performance enhancements like an M Sport rear differential, M Sport brakes, and an Adaptive M suspension. The base X3 30 xDrive, with its 255-horsepower turbocharged 2.0-liter four-cylinder engine, offered a sprightly performance, reaching 60 mph in six seconds. Both models came standard with all-wheel drive and a 48-volt mild hybrid system. The X3 M50's firm ride was balanced by its impressive handling and braking capabilities. The X3 also boasted a tight turning radius and a towing capacity of 4,850 pounds for the M50, making it a versatile choice for performance enthusiasts.

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 to 22.6 cubic feet with the rear seats in place, 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 offered good forward visibility and was easier to park than larger rivals.

The 2026 BMW X3 featured heated, power-adjustable front sport seats with Veganza upholstery, providing comfort and support. Rear passengers, however, might find the seating less accommodating.

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 like a dashcam and rear-seat entertainment system available.

The 2026 BMW X3's dashboard was dominated by the BMW Curved Display, featuring a 12.3-inch digital driver display and a 14.9-inch touchscreen infotainment system.
