BMW Launches Sixth-Generation eDrive Electric Drive System with Over 900km Range, Claiming "Accurate Specifications"
BMW Group has officially launched its sixth-generation eDrive electric drive system. As a core power solution for next-generation vehicles, the system achieves a breakthrough range of over 900km under CLTC conditions, thanks to its full-range 800V high-voltage architecture, revolutionary large cylindrical batteries, and efficient motor combination, supported by measured data to back up its promise of "accurate specifications."
The most significant upgrade in the sixth-generation eDrive is the full-range 800V high-voltage architecture and the mass-produced 4695 large cylindrical battery, which increases energy density by 20%. Combined with system efficiency optimization, it achieves a 30% increase in range and supports a maximum charging power of 400kW, allowing for a 400km range boost in 10 minutes and 10%-80% charging in 21 minutes.
The new-generation BMW iX3 50 xDrive is equipped with a 108.7kWh battery pack, offering a WLTP range of 805km and exceeding 900km under CLTC conditions. The official power consumption is as low as 15.1kWh/100km, with a very high actual range achievement rate.
In addition to the battery, the electric drive has also been significantly upgraded. The motor configuration adopts an innovative combination of a front asynchronous motor (ASM) and a rear electrically excited synchronous motor (EESM), achieving a rare earth-independent drive architecture and eliminating reliance on permanent magnet materials.
The flat wire winding slot fill rate reaches 80%, reducing copper loss by 12%. The composite cooling system reduces the temperature rise rate under continuous high load by 30%. The silicon carbide (SiC) semiconductor inverter reduces energy loss by 40%. The highly integrated design reduces the weight of the electric drive unit by 10% while improving reliability.
The BMW Energy Intelligence Control System realizes vehicle-level dynamic energy management, increasing the overall system efficiency by approximately 20%, reducing energy loss by 40%, and reducing costs by 20%, achieving a balance between performance and economy. It also supports remote OTA continuous performance optimization and is equipped with intelligent safety electronic insurance to ensure the safety of the high-voltage system.
The system supports flexible expansion from a single-motor rear-wheel drive to a four-motor all-wheel drive, with a maximum output of 1MW (1340hp), meeting the needs from daily commuting to M series high performance. It adapts to diverse scenarios such as camping mode and vehicle-to-load (V2L), and the efficient thermal management system can adapt to extreme environments from -30℃ to 55℃.
