What is the difference between CLTC and NEDC?

[ReaganLynn]

The biggest difference between CLTC and NEDC is that the CLTC test cycle yields a longer range than NEDC. The differences between the two are as follows: NEDC: The NEDC range test standard is not only outdated but also significantly differs from actual road conditions in China compared to Europe. This discrepancy means that a vehicle might achieve 500 km in NEDC testing, but consumers may only get 400 km or even less in real-world usage. Conditions like highway driving or using air conditioning can further reduce the range. 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 for a three-year research and development effort. It involved data from 41 representative cities, nearly 4,000 vehicle models, and over 30 million kilometers of driving data to finalize the test standard. Directly speaking, the CLTC test cycle covers a broader and more comprehensive range of conditions and has a longer duration.
