BMW is conducting the final validation phase for the fifth-generation X5 Sports Activity Vehicle (SAV), with prototype vehicles undergoing calibration and performance testing around BMW Group s manufacturing facility in Spartanburg, South Carolina, ahead of production launch.
The next-generation X5 lineup will introduce multiple propulsion technologies, including the first fully electric BMW iX5, which is scheduled to be followed by BMW s first series-production hydrogen-powered vehicle, the BMW iX5 Hydrogen, in 2028. The range will also include gasoline and diesel powertrains equipped with 48V mild-hybrid systems alongside plug-in hybrid variants.As part of the final development program, international media representatives participated in evaluation drives of several pre-production models, including the BMW X5 40 xDrive, BMW X5 50e xDrive plug-in hybrid, and the all-electric BMW iX5 60 xDrive.
The battery-electric BMW iX5 is built around BMW s sixth-generation eDrive platform, featuring an 800-volt electrical architecture and a newly developed cylindrical-cell battery design. With a usable battery capacity of up to 144 kWh for the U.S. market, the model is expected to carry the largest battery pack fitted to a fully electric BMW vehicle to date. Power is delivered through dual electric motors driving both axles via BMW s electric all-wheel-drive system.
BMW also provided additional details on the future BMW iX5 Hydrogen, which combines a next-generation fuel cell system with the company s newly developed Hydrogen Flat Storage technology and a dedicated high-voltage battery. The third-generation fuel cell architecture has been engineered to deliver improved packaging efficiency, power density, and operational performance.
The new X5 platform has also undergone chassis and ride optimization. Customers will be able to specify wheel sizes up to 23 inches, while adaptive suspension technology with electronically controlled dampers will be fitted as standard. BMW stated that the vehicle's near 50:50 weight distribution contributes to improved stability, comfort, and driving dynamics.
The latest testing milestone highlights BMW s strategy of offering multiple propulsion options on a single vehicle platform, spanning battery-electric, hydrogen fuel-cell, hybrid, and conventional powertrain technologies as the company expands its next-generation mobility portfolio.
