Electric Car Range Test: BMW iX3 Wins, XPeng X9 Surprises 2026

The electric car range test conducted by the Norwegian Automobile Federation (NAF) has once again delivered clear results: when it comes to going the distance, BMW and Mercedes are leading the pack, with only Chinese models like the XPeng X9 posing a serious challenge. The summer test, which put 24 of the market's most representative EVs through their paces, highlighted just how far electric vehicles have come—and which brands are truly delivering on their promises.

BMW iX3: The Undisputed Range King

The BMW iX3 emerged as the clear winner, covering an impressive 781 kilometers before coming to a complete stop. That figure even surpasses its WLTP homologated range of 770 kilometers, a rare feat in the EV world where real-world range often falls short of official estimates.

What makes the iX3's performance so remarkable is its combination of a massive 108.7 kWh battery and remarkably low consumption of just 14.2 kWh/100 km. For a vehicle of its size, weight, and frontal area, this efficiency is enviable and underscores BMW's engineering prowess in maximizing range without sacrificing performance.

XPeng X9: The Chinese Surprise

While the BMW iX3's victory might not shock those familiar with the latest EV launches, the XPeng X9 provided the biggest surprise of the test. This Chinese electric minivan, not yet available in Spain, homologates 580 kilometers under the WLTP cycle. However, in the Norwegian test, it managed to cover 646 kilometers before stopping—a significant overachievement.

The X9's performance signals that Chinese manufacturers are not just competing on price but are now delivering real-world range that can rival established European brands. This shift is crucial for consumers who have long viewed Chinese EVs as inferior in technology and reliability.

Why the NAF Test Matters

The NAF's range tests are highly regarded because they are conducted under real-world conditions, unlike laboratory-based WLTP assessments. By driving the vehicles until they stop, the test provides a transparent comparison that helps buyers make informed decisions.

This summer's test is particularly relevant as range anxiety remains one of the main barriers to EV adoption. Knowing which cars actually deliver on their promises can significantly impact purchasing decisions and consumer confidence.

Key Takeaways from the Test

• BMW iX3 exceeded its WLTP range, proving that some manufacturers are conservative in their estimates.
• XPeng X9 outperformed its official range by a wide margin, showcasing Chinese EV advancements.
• Real-world range tests like NAF's are essential for cutting through marketing claims.
• Efficiency (kWh/100 km) is just as important as battery size for achieving long range.
• Chinese brands are becoming serious contenders in the global EV market.

Comparison of Top Performers

While the table only includes two models, the full test covered 24 vehicles, with the BMW and XPeng standing out for their range achievements.

What This Means for EV Buyers

For consumers, the results reinforce the importance of looking beyond WLTP figures. While official range is a useful starting point, real-world tests like NAF's provide a more accurate picture of what to expect.
