In the NAF (Norwegian Automobile Federation) hosted El Prix 2026 Summer Electric Vehicle Range Test — the world’s largest real-world EV testing event — the Chinese brand XPENG X9 achieved a 646 km driving range result, reaching 111.4% of its WLTP rated range, exceeding the official specification by 11.4%. It ranked first in range efficiency among all 24 participating vehicles.
At the same time, XPENG X9 also ranked first in charging speed tests. This result not only breaks the range record of Chinese brands in authoritative European testing, but also, during a sensitive period when the EU is considering additional tariffs on Chinese EVs, provides strong technical validation for Chinese high-end electric vehicle exports to Europe.

Test Scale：24 EVs, covering mini cars, compact sedans, SUVs, and large MPVs
Test Method：Real public road driving in Norway during summer conditions. All vehicles start simultaneously and drive until fully depleted (0% SOC), recording actual distance traveled.
Test Route：Mixed road conditions around Oslo, Norway (city + highway + rural roads), including altitude variation typical of Nordic driving environments.
Announcement Time：Late June 2026
XPENG X9 Result：646 km real-world range, WLTP rated range approx. 580 km, achieving 111.4% efficiency; also ranked first in charging speed.
XPENG Official Response：XPENG stated that the X9’s 800V high-voltage SiC platform and proprietary thermal management system are the core technologies enabling this “reverse under-reporting” result, confirming its real-world efficiency in European driving conditions.

WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is a laboratory-based standardized range measurement. Real-world driving is affected by temperature, wind, altitude, and driving behavior, and typically results in 10–30% lower range than WLTP.
The XPENG X9 achieving 11.4% above WLTP is extremely rare, indicating that its energy efficiency management system is significantly above segment average.

The XPENG X9’s performance in the NAF El Prix 2026 significantly strengthens its position in global export markets, shifting the narrative from price competition to technology-led competitiveness in efficiency and charging performance.
In Europe, the large MPV segment remains relatively underserved, with limited options that combine long range, fast charging, and advanced electric architecture. The XPENG X9 addresses this gap through its 800V SiC platform, low drag design, and verified real-world efficiency, making it more competitive in the premium family vehicle segment.The strong credibility of the NAF El Prix test adds substantial trust value, as it is one of Europe’s most respected independent EV evaluations. Achieving 111.4% WLTP efficiency under real-world conditions provides third-party validation that reinforces consumer confidence.
At the same time, increasing regulatory pressure on Chinese EV imports in Europe is pushing brands toward higher-value positioning. In this context, verified performance results like those of the XPENG X9 support its transition into a technology-driven premium product category rather than a price-sensitive competitor.
Overall, the combination of strong test validation, limited competition in the MPV segment, and growing demand for efficient long-range EVs creates a favorable export opportunity in Europe and other global markets.
The 646 km and 111.4 percent WLTP result represents a major milestone for Chinese EVs in the most authoritative European real-world test.
