BMW iX3 50L Range Record 2026: How Far Can the Long-Wheelbase EV Really Go

1,030.2 km on a single charge — with 5% battery still left at the finish. The China-only BMW iX3 50L has set a new range record for the brand's electric vehicles, driving from BMW's production site in Shenyang to the company's research center in Beijing. But the number shouldn't be read as a real-world benchmark: BMW carefully planned the route, speed and energy use specifically to test the limits of efficiency.

The contrast with the official rating is still striking. The long-wheelbase iX3's certified CLTC range is 919 km, so the test added 111.2 km, or 12.1%, on top of that — and the car wasn't even fully drained. The certification data also lists consumption of 13.6 kWh/100 km, all-wheel drive, 351 kW — about 477 hp — and an 800-volt architecture.

It's the conditions that separate a record from a result that means something to an actual owner. Back in May, the same iX3 50L covered more than 800 km around Qinghai Lake, with roughly 2,000 meters of elevation change, rain, snow and the climate control running the whole way. That drive ended with 2% charge left and average consumption of 12.6 kWh/100 km. BMW officially lists the battery's usable capacity at 108.7 kWh and credits the efficiency to cylindrical cells, regenerative braking, aerodynamics and thermal management.

So the 1,030 km figure is better read not as a new "real-world range," but as the upper limit of what the system can do under a carefully chosen scenario. For comparison, the global iX3 50 xDrive covered 781 km in NAF's independent summer range test — a result much closer to an everyday drive, though that's a different, standard-wheelbase version tested with a different methodology.

The China-only iX3 is built primarily for the local market: its wheelbase reaches 3,005 mm, charging tops out at 400 kW, and BMW claims more than 900 km of CLTC range. Ten minutes at a suitable station can add up to 400 km of estimated range, and a 10-80% charge takes about 21 minutes.

The next stage is already commercial: on August 21, BMW will open pre-orders for the iX3 50L in China at the Chengdu auto show. From that point on, price, real-world trim levels and whether the claimed efficiency holds up in customers' hands will matter more than the record number.
