Reception

Reviews and awards

The first-generation BMW X4 (F26; 2014–2018) earned positive reviews for its engaging handling and sporty dynamics, with describing it as a "satisfying thing to drive" thanks to its responsive and turbocharged engines. However, critics frequently highlighted drawbacks in practicality, such as limited rear headroom and cargo space due to the sloping roofline, which Auto Express noted compromised family usability compared to the standard X3. The model received no major automotive awards during its run. The second-generation X4 (G02; 2018–2025) garnered higher acclaim for refined performance and style, achieving a 4.0 out of 5 rating from for its entertaining driving experience, powerful engine options, and design-forward exterior. Edmunds awarded it 7.5 out of 10, praising the smooth, fuel-efficient powertrains and balanced handling that made spirited drives enjoyable, though it appeared sportier than its actual pace suggested.
