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 base G 550 models. The G-Class offered a range of wheel options and an extensive Manufaktur program for customization. Inside, the G-Class boasted a luxurious interior with a sci-fi aesthetic, featuring ambient lighting and metallic trim. The dashboard prominently displayed switches for differential locks, and AMG models sported a more dynamic steering wheel.

The 2026 BMW X3, particularly the X3 M50 variant, was a compact SUV that offered a blend of performance and luxury. Priced from $81,592, the test model featured upgrades like a Frozen Deep Grey paint job and Merino leather upholstery, pushing the MSRP over $100,000. The X3's design was described as "monolithic," with an illuminated grille surround that divided opinions. The interior, while equipped with advanced lighting and touch-sensing controls, was criticized for its austere feel. BMW attempted to enhance the cabin with artificial leather and upgraded trim for the 2026 model. Despite these efforts, the X3's interior quality was seen as lacking for its price point.
