What is the comparison result between CLTC and NEDC range?

[LucyLynn]

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 More relevant information is as follows: 1.NEDC: The NEDC range test standard is not only outdated, but there are also significant differences between European and domestic road conditions.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.

In the new energy vehicle circle, I often get asked about the differences between these two standards. Simply put, the CLTC test cycle is more 'considerate' towards electric vehicles—it features longer idle times, more constant speed segments, a maximum speed of only 114 km/h, and the air conditioning is set at the most energy-efficient 23°C throughout. In contrast, the NEDC test is much more aggressive, with more rapid acceleration, higher average speeds, and the air conditioning always on. Therefore, in real-world tests, the same car's CLTC range is generally 10% to 20% higher than its NEDC range. Recently, while helping a friend choose a car, I noticed that the BYD Seal has a CLTC-rated range of 700 km, which roughly translates to about 630 km under NEDC. It's advisable to focus on the CLTC figures when evaluating cars, as they better reflect domestic driving conditions.

The difference between CLTC and NEDC range fundamentally stems from the physical parameters of testing protocols. The former is based on driving data collected from 41 Chinese cities, with an average speed of only 29km/h and idling accounting for 22%; the latter has an average speed of 34km/h with merely 15% idling. Their power output curves also differ: CLTC's acceleration ≤ 0.15m/s² accounts for 74% of operating conditions, significantly higher than NEDC's 47%. Electric motors demonstrate higher efficiency under low loads, resulting in approximately 15% overall inflation in CLTC range figures. However, neither accounts for energy consumption degradation in extreme cold or high-speed scenarios.

After driving over 20 electric vehicles, I found the key difference between CLTC and NEDC range lies in energy recovery mechanisms. In China's CLTC testing cycle, regenerative braking accounts for 46% of total deceleration conditions, while NEDC only accounts for 31%. During test drives, I specifically compared: in urban driving with strong regeneration mode enabled, the displayed range depletion rate almost matched CLTC data; during intercity highway driving with fewer recovery opportunities, range dropped faster than NEDC. Therefore, when using cabin heating in winter or defogging during heavy rain, actual range often falls short of even NEDC figures.

When choosing an electric vehicle, salespeople often emphasize the CLTC range, but it's important to pay attention to standard conversions. For example, the Tesla Model 3 Rear-Wheel Drive version is rated at 606km under CLTC, which converts to approximately 554km under NEDC using the national standard conversion formula. Last week's rental car test showed that driving at a steady 80km/h on Shanghai's Middle Ring Road achieved 530km, close to the NEDC data. However, during Friday's evening rush hour stuck on the elevated road, the range surprisingly approached the CLTC's 588km. It's recommended to prioritize WLTC data (which falls between the two) or directly refer to actual range shares from owner forums.
