What is the relationship between the GB standard driving cycle range and NEDC?

The relationship between the GB standard driving cycle range and NEDC is: The standard for national certification is GB/T18386-2005 "Test methods for energy consumption and range of electric vehicles." This standard mainly references the European NEDC standard, so most Chinese automakers label their vehicles with the NEDC range. Below is an extended introduction: GB standard driving cycle range: The range test conducted by China's Ministry of Industry and Information Technology is entirely performed on a chassis dynamometer, using fully charged vehicles with non-essential electrical equipment turned off for sample testing over a certain distance. After determining the vehicle's energy consumption rate, the range is calculated. NEDC: NEDC (full name: New European Driving Cycle) consists of urban and suburban driving cycles. Compared to the ideal 60 km/h constant-speed range, NEDC is closer to actual driving conditions and more meaningful as a reference.
I recently researched the issue of electric vehicle range and found that NEDC is an old European testing standard with slow speed variations, often overestimating actual performance. After China introduced its own national standard, the CLTC cycle, which simulates domestic urban congestion and frequent start-stop scenarios, the range figures are typically 10-20% lower than NEDC but closer to real-world driving. As an average car owner, I prioritize CLTC data when choosing a vehicle because it gives me less range anxiety in traffic jams. NEDC used to be mainstream but has now been replaced by CLTC. Automakers are labeling data according to the new standard, and this shift has boosted consumer confidence. Remember, when buying a car, don’t be drawn to the outdated NEDC—choosing range ratings adapted to domestic road conditions is the safer bet.
