BMW iX3 50 xDrive tops the NAF summer test: 781 km on a single charge

Norway’s NAF tested 24 EVs in identical summer conditions. The BMW iX3 50 xDrive went the farthest, while XPeng X9 beat its WLTP rating by the largest margin.

Norway’s automobile club NAF has run its latest real-world EV range test. The summer edition pitted 24 models against each other on the same route, in identical conditions, all starting with a full battery. The winner on outright distance was the BMW iX3 50 xDrive — 781 km on a single charge.

The test took place on 3 June in close to ideal conditions: temperatures sat between 12 and 18 °C and the roads were dry. The route mixed city streets, secondary roads, motorways and mountain climbs. A car was pulled out once it could no longer hold the speed limit due to low charge. The BMW’s win owed a lot to its large 108.7 kWh battery. Second place went to the Lucid Gravity with 720 km — meaning the iX3 beat it by 61 km.

Outright range, however, is only half the story. The most accurate car against its own claim was the XPeng X9: the Chinese minivan covered 646 km against an official figure of 580 km, beating it by 11.4%. At the other end of the table sat the MG IM6, which managed 446 km instead of the promised 505 km — a 11.7% shortfall. The Toyota bZ4X matched its WLTP figure almost exactly, while Mercedes produced mixed results: the GLB and GLC exceeded their claimed range, but the electric CLA fell 4.7% short.
