The BMW i3 has evolved significantly since its debut, and understanding the battery capacity variants is crucial for owners considering replacement or upgrade options. As a CNS BATTERY expert, I’ve analyzed real-world performance data to help you make informed decisions about your electric vehicle’s power source.
Understanding BMW i3 Battery Options Across Model Years
The BMW i3 lineup features multiple battery configurations depending on the production year and market region. Here’s what you need to know:
Standard Battery Variants
2024-2026 Models typically come with these options:
- eDrive35L: Approximately 70 kWh usable capacity
- eDrive40L: Around 80 kWh usable capacity with extended range packages
The CLTC range reaches up to 625 kilometers on higher-end variants, representing a significant improvement over earlier generations. This evolution matters when considering battery replacement scenarios.
