What is the comparison result between CLTC and NEDC range?
2 Answers
CLTC test cycle yields longer range than NEDC. More relevant information is as follows: 1.NEDC: The NEDC range test standard is not only outdated, but there are also significant differences between European and domestic road conditions. This results in the same vehicle potentially achieving 500 km in NEDC tests, while consumers may only get 400 km or less in actual usage. Under conditions like highway driving or air conditioning use, the range could be even shorter. 2.CLTC: CLTC was developed under the leadership of the Ministry of Industry and Information Technology, with the China Automotive Technology and Research Center organizing industry experts to conduct three years of research. It analyzed data from 41 representative cities, covering nearly 4,000 vehicle models and over 30 million kilometers, ultimately establishing this test standard. Directly speaking, the CLTC test cycle has broader coverage, is more comprehensive, and lasts longer.
I've been driving an electric vehicle for several years and noticed that the CLTC range is always significantly higher than the NEDC. CLTC is China's own testing standard, specifically designed to simulate common local scenarios like traffic congestion and low-speed driving, with more stops and fewer accelerations, plus more favorable test temperatures. NEDC is the older European standard with an overly idealized testing procedure—constant speed with air conditioning on. As a result, the same car might be rated at 500 km under CLTC but only around 450 km under NEDC. Honestly, for daily city commuting at lower speeds, the actual range tends to align more closely with CLTC figures, while highway driving sees faster battery drain, similar to NEDC. When choosing a car, don’t just focus on the numbers—consider your actual commuting conditions.
