What reviewers say
Reviewers agree the 3 Series remains the best-driving compact executive saloon, with excellent infotainment, a high-quality interior and strong, efficient engines, the 330e plug-in hybrid included. The common criticisms are high prices once options are added, a firm ride on the standard M Sport suspension, a narrower engine range without diesels, and ventilation controls less user-friendly than before.
