The X3 is completely redesigned for 2025. Highlights include a sharper exterior, a fancier cabin and new technology. Under the hood, all the engines feature mild hybrid technology, starting with the standard 2.0-litre four-cylinder unit producing 255 horsepower. A 3.0-litre inline six-cylinder rated at 375 horsepower is also available. BMW is expected to add a redesigned X3 M for performance enthusiasts at a later date along with a plug-in hybrid model.
