Redesigned for 2025, the fourth-generation X3 grows slightly in length and power, and it adopts a high-tech, minimalist interior design. It launches in two trims: 30 xDrive with a 255-hp, 2.0-liter turbocharged inline-four and M50 xDrive with a 393-hp, 3.0-liter turbocharged inline-six engine. Each is paired with an eight-speed automatic transmission, augmented with a 48-volt mild-hybrid system, and employs all-wheel drive. The optional driving assistance suite includes adaptive cruise control and lane centering assistance. The dash is dominated by a wide, curved display that houses the iDrive 9 infotainment system, available with numerous connected features. Among the notable upgrades is the ability for navigation instructions to be overlaid on the road ahead using the head-up display for augmented reality.
