BMW’s long-wheelbase iX3 covered 1,030.2 kilometers, or 640 miles, on a single charge during an internal test in China. The SUV still had five percent battery remaining when it arrived at its destination.
That number eclipses the iX3 50L’s official CLTC range of 919 kilometers by more than 100 kilometers. It also sets a new range record for any BMW electric vehicle.
Engineers drove the Neue Klasse-based SUV from BMW’s Shenyang production plant to its R&D center in Beijing. The route was carefully selected, the conditions controlled, and BMW was quick to say that your mileage will vary depending on weather, traffic, speed, load, and air conditioning settings.
Fair enough. But 640 miles with juice to spare is still a number that demands attention, even with caveats stapled to it.
This is the second long-range demonstration for the new iX3 in recent months. BMW previously drove one 805 kilometers around Qinghai Lake in what the company described as a more real-world scenario. The pattern is clear: BMW wants to prove its official range numbers are conservative, not aspirational.
That cuts against the grain of an industry where range claims have become a credibility problem. Most automakers quote numbers their customers will never replicate outside a lab. BMW is trying to flip the script by beating its own spec sheet on actual roads.
Whether that holds up across tens of thousands of customer miles is another question entirely.
BMW credits its sixth-generation cylindrical battery cells, aerodynamic bodywork, regenerative braking calibration, and refined thermal management for the efficiency. The long-wheelbase iX3 50L carries a larger battery pack than the standard model. The stretched platform gives BMW more room to package cells without compromising cabin space.
The “L” suffix is the catch. This long-wheelbase version is built for China and will ship to select markets, but Europe and North America are not on the list. Buyers in those regions will get the standard-wheelbase iX3, which shares the Neue Klasse architecture but won’t match the 50L’s battery capacity or range ceiling.
Preorders for the iX3 50L open in China on August 21 at the Chengdu Motor Show. BMW is clearly timing these range demonstrations to build momentum ahead of that launch window.
The Chinese EV market is the most competitive on earth. Domestic brands like BYD, NIO, and Xpeng have been pushing range and efficiency numbers for years, often at price points that make German luxury marques uncomfortable. A 1,000-kilometer range test from BMW is as much a defensive move as it is a flex.
The CLTC rating system used in China is notably more generous than WLTP or EPA standards, so these numbers would shrink considerably under Western testing protocols. A 919-kilometer CLTC rating might translate to something closer to 500 miles on WLTP, and less under EPA rules.
BMW has not disclosed what the standard-wheelbase iX3’s range will look like in markets that use stricter measurement standards. That number, whenever it arrives, will tell us more than any controlled highway run between two Chinese cities.
