Starting in December 2026, the BMW X3 M50 xDrive will feature an upgraded turbocharged 3.0-liter inline-six engine matching the output of the newly revealed M350 xDrive sedan.The retuned 48-volt mild-hybrid setup output jumps by 45 metric horsepower to 443 hp (rated at 437 hp in U.S. specification). That extra muscle knocks the zero-to-62 mph (100 km/h) sprint down to 4.4 seconds-or 4.1 seconds when using a one-foot rollout method. Crucially for global markets, the extra power comes alongside recalibrations that bring the straight-six into full compliance with Euro 7 emissions standards. The power boost applies to all M50 xDrive models rolling off the line starting in December, regardless of options.2027 X3 M50 Black Package: All The Details2027 X3 M50 Black Package: All The DetailsView Gallery25 photosNew Black Package Adds Stealth Styling and AlcantaraAlongside the engine bump, BMW is introducing an exclusive Black Package specifically for the X3 M50 xDrive.
