BMW i5 Efficiency Upgrades
The BMW i5 is set to receive efficiency improvements in 2025, resulting in an 8-9% increase in efficiency across the board. These upgrades include silicon carbide semiconductors in the power electronics, optimized wheel bearings, and low-rolling-resistance tires. The WLTP range of the i5 will be increased by up to 29 miles (47 km) as a result of these enhancements, although EPA figures have not yet been released.
Improved Range and Performance
With the introduction of the new 19-inch aerodynamic wheel and tire combination, the single-motor i5 eDrive40 and the xDrive40 dual-motor model achieve significant improvements in electricity consumption. The upgrade results in a 8-9% increase in efficiency for both models. These enhancements are expected to have a positive impact on the i5’s handling, which has been praised for being excellent in its class.
BMW iX Enhancements
The BMW iX crossover has also received upgrades to improve its efficiency and range. The 2026 iX model has been restyled to keep it up to date, while the big-battery model’s EPA range has been increased to 340 miles. BMW claims that the new iX is 10% more efficient than its predecessor. These enhancements are part of BMW’s commitment to improving the performance and sustainability of its electric vehicles.
Upgraded Onboard Charger
In addition to improvements in the i5 and iX models, BMW is also introducing a more powerful onboard charger for its plug-in hybrids. Models such as the X1, 2 Series Active Tourer, 7 Series, and XM will now be equipped with an 11-kW onboard charger, up from the previous 7.4 kW charger. This upgrade is expected to significantly reduce charging times for these vehicles, potentially bringing them below the two-hour mark for a full charge.
