Cold Weather Impact: Like all EVs, the range suffered noticeably in sub-zero temperatures as power was diverted to battery pre-conditioning and cabin heating. During the coldest months, the highway range could dip toward 180 miles (290 km), requiring more conservative driving and careful route planning—a key insight for prospective EV buyers in cold climates.
Battery Degradation: A health check at the 30,000-mile mark indicated minimal degradation, with the battery still showing close to 98 percent of its original usable capacity—a strong indicator of the effectiveness of BMW’s thermal management system.
Charging Performance and Reliability
The i4 is equipped with a strong 205 kW peak DC fast-charging rate. Consistency was the standout feature.
DC Fast Charging: In our extensive testing across various networks, the i4 consistently performed near its maximum capacity. We averaged a charging time of 35-38 minutes to go from 10 percent to 80 percent State of Charge (SoC). This reliability made long-distance EV travel surprisingly painless, especially when coupled with the excellent Plug & Charge functionality.
Level 2 Home Charging: The onboard 11 kW AC charger is robust, achieving a full 0-100 percent charge in approximately 8.25 hours on a dedicated Level 2 home charger. For the daily commute, overnight charging was always sufficient to top up the battery, eliminating charging anxiety entirely.
Cabin and Technology: Longevity and Usability
The interior is where the i4 truly separates itself from many EV competitors, retaining BMW’s reputation for premium materials and intuitive, driver-focused technology.
