BMW is preparing to launch the 2027 iX5, an electric SUV that stands out for its exceptionally large battery pack. With 144 kWh of usable capacity for the U.S. market, the iX5 xDrive 60 will feature the biggest battery ever installed in an electric BMW. The model blends new battery technology with BMW’s existing platform, aiming to set a new benchmark in the segment.
BMW iX5: Pushing Battery Limits
The upcoming BMW iX5 will offer a 144 kWh usable battery in the U.S. and 141 kWh in Europe, according to the automaker. This makes the iX5 xDrive 60 the largest-battery electric BMW to date. The SUV incorporates some Neue Klasse technology, such as sixth-generation cylindrical cells and an 800-volt architecture, but continues to use BMW’s Cluster Architecture platform.
BMW has implemented cell-to-pack technology in the iX5, removing modules and structural layers to optimize space and weight. Engineers have also worked to keep the floor height low despite the battery’s size.
Engineering and Handling
The iX5’s large battery contributes to a curb weight of roughly 3,000 kg (~6,600 lbs), as reported by Autocar. To address the challenges of this weight, BMW has decoupled the suspension’s springs and dampers, increasing the air chamber’s internal volume for improved ride comfort. The adaptive dampers and anti-roll bars have also been repositioned to enhance the balance between ride and handling.
Final calibration drives for the iX5 are underway at BMW’s Spartanburg plant, signaling that the model is nearing production readiness.
Platform and Powertrain Options
While the iX5 uses some of the latest battery and electrical technologies, it is built on BMW’s previous-generation Cluster Architecture rather than the all-new Neue Klasse platform. In addition to the electric variant, BMW plans to offer the X5 with four other powertrain options: mild hybrid gas, diesel, plug-in hybrid, and a hydrogen fuel-cell version.
Competitor Comparison
The iX5’s battery capacity surpasses several key competitors. The Porsche Cayenne Electric features a 113 kWh gross battery, while the Lucid Gravity Grand Touring offers 123 kWh gross. The Rivian R1S with the optional Max battery pack provides 140 kWh usable capacity. Only large General Motors trucks and SUVs, such as the Chevy Silverado EV, GMC Hummer EV, and Cadillac Escalade IQ, offer battery packs exceeding 200 kWh.
Historical Context
BMW’s move comes as global car sales reached 10,632,381 units in 2024, marking a 1.8% year-over-year increase. In Europe, the Renault Group holds a 10.2% market share as of 2025, highlighting the competitive landscape for electric SUVs in the region.
Why this matters
The BMW iX5’s introduction of a 144 kWh battery sets a new standard for electric SUVs in its segment, potentially offering greater range and utility for buyers. The combination of advanced battery technology and multiple powertrain options reflects BMW’s strategy to address diverse market needs as electrification accelerates.
What this means for buyers
Buyers interested in long-range electric SUVs will find the iX5 a compelling option, especially given its large battery and advanced features. Those considering alternatives should compare the iX5’s specifications with rivals like the Porsche Cayenne Electric, Lucid Gravity, and Rivian R1S. Regional availability and final range figures will be important factors to watch as the iX5 approaches launch.
