The sixth-generation BMW 5 Series (F10 sedan, F11 Touring wagon, and F18 long-wheelbase version for China) marks a return to classicism after the controversial Chris Bangle era (E60). Positioned as a benchmark premium executive car, it shares its architecture with the 7 Series (F01), which gives it imperial comfort, high-level sound insulation, and impeccable finish quality. On the other hand, it carries a significant weight. The mid-2013 facelift (LCI) is crucial: it corrects many early flaws, modernizes the infotainment (transition to the iDrive NBT system), and gradually introduces new, much more reliable engines (notably the transition from the criticized N47 to the robust B47 diesel).
The BMW 5 Series F10/F11 is a fantastic executive car, but its reliability record is split in two. Early production models (2010-2013) are plagued by costly problems (N47 diesel timing chain, N63 V8 gasoline). In contrast, facelifted versions (LCI from mid-2013, and especially 2014 for the arrival of the B47 engine) are excellent choices. The best diesel buy is a 520d (B47 engine with 190 hp, post-2014) for practicality, or a 530d (N57 with 258 hp) for passion. Avoid 550i models and 520d models from before 2014 without a clear service history. Demand a vehicle with the EGR recall performed and an automatic gearbox that has been serviced.
