Full system breakdown + what I would do

Should You Buy the 2015 BMW i3?

The 2015 BMW i3 presents a unique proposition: a stylish, efficient EV with BMW's premium touch. While its electric drivetrain is generally robust, the vehicle carries typical BMW complexity in its electronic systems, and the optional Range Extender (REX) introduces potential gasoline engine issues, elevating the risk profile from a pure BEV model. For those seeking an affordable entry into premium EV ownership, it can be a good choice, but it demands diligent pre-purchase inspection and an understanding of its unique maintenance needs.

Biggest Strengths

  • Robust electric motor and single-speed transmission
  • Corrosion-resistant carbon fiber reinforced plastic (CFRP) body shell
