BMW iX5 Gets a Range Bump Before It Reaches U.S. Showrooms

BMW has quietly raised the range bar for its first fully electric X5, telling reporters at the SUV’s press launch that the iX5 should now carry an estimated EPA rating of 450 miles — up from the 435 miles the company floated when it detailed the iX5 60 xDrive earlier this year. The figure isn’t official yet, and BMW says the final EPA number will land in the coming weeks.

The extra miles come largely from sheer battery size. The iX5 packs a 144-kilowatt-hour pack, the biggest BMW has ever put into a production vehicle and one of the largest units fitted to any SUV on sale. BMW arrived at that capacity by using the same cell count and basic layout as its iX3 and i3, but with taller cells — 46120 cylindrical units in the iX5 versus the 4695 cells in its smaller stablemates, a 25-millimeter height increase that adds usable energy.

BMW’s internal reasoning for chasing such a big number is straightforward. Michael Ahlers, who heads the X5 project, said the company concluded that once drivers see roughly 400 miles of range, range anxiety largely fades. The extra cushion beyond that is meant to absorb the real-world habits that drain a battery faster than lab testing suggests — highway speeds, air conditioning, cold mornings. A product manager for BMW’s luxury line described the projected 450-mile estimate as “really fantastic” for a vehicle of this size.

The iX5 isn’t just about distance. BMW says the SUV will support 460-kilowatt charging, enough to take the pack from 10 to 80 percent in about 22 minutes. That combination of a very large battery and very fast charging puts the iX5 in rare company among electric SUVs.

The broader context matters here: 400-plus-mile EPA ratings were once a tiny club, opened by the Tesla Model S in 2020. BMW’s Neue Klasse generation has rapidly expanded that group, with the iX3 rated at 435 miles and the i3 recently posting 468 miles. The iX5 is set to go on sale in the first quarter of 2027, and its final EPA certification will confirm whether BMW’s 450-mile target holds.
