About the BMW X4
The BMW X4 is a compact luxury crossover SUV manufactured by BMW from 2014 to 2025. It is marketed as a sports activity coupé (SAC), the second model from BMW marketed as such after the X6, and features styling elements and the roofline of a traditional two-door coupé. The X4 is widely considered as a "coupé" version of the X3, trading its practicality with a sloping rear roof which offers a sportier styling. BMW has indicated 2025 will be the X4's final model year.
