The top trim level of the Tesla Model 3 AWD Long Range (Highland) has an official range of 713 km under CLTC (China Light-Duty Vehicle Test Cycle) conditions. It reached 568 km during the test, 79.7% of the official value.

Nio ET5 2022, with a 100 kWh battery, has a CLTC range of 640 km and reached 455 km during the test, which is 72.6% of the official value. In March, Nio launched the 2024 facelift of its mid-size sedan; the one tested was the 2022 version.

      • Yes, Dongchendi works with 810 CLTC range. However Xiaomi claims the official CLTC range of Max variant is only 800 km CLTC. It is confusing, I will dig in further into this.

    • Hi HJE and Gang Du, Dongchendi apparently used different kinds of tires, which gave SU7 Max an additional range, so their test car had an 810 CLTC range, 10 km more than on standard tires. I changed the table inside the article. Thanks for your input.

  1. What about test conditions?
    Speed? Passengers? Weather?

    Any additional info will be welcome.

    • Hi Leo, please have a look at my reply to Mr. Truth above. Although, you will never find the real ‘truth’ about range – there are too many criteria. It may even depend on the driver in a comparison test with many cars, at the same time. But comparing is always good, also with the different ways to measure.

      My own car, a BYD Atto 3 – does almost fulfill the advertised 430 WLTP kilometers on a normal summer day with 20 degrees. But in minus 10 cold degrees in winter, it’s reduced by at least 20 – 25%. Which is normal for todays NMC and LFP batteries. Of course charging time also differ with temps.

        • I still don’t understand why you deleted my (long, but correct and polite) comment to Mr. Truth, Jiri. You need to “educate” me. :))

          • Hi Knut, I didn’t delete any comments here. Also don’t understand why you attack me with Mr Truth comments.

  2. Sorry, Jiri. I did not attack anyone. I never do. I wrote a nice reply to Mr. Truth. Explaining to him, the what he asked for.

    But my comment came up with a reply that it needed to be controlled or something. Then it disappeared. So no attacks. Just something strange that happened. Sorry — really.

    You know I appreciate you and your colleagues does on CNC. Without your news and articles daily it would be impossible to stay updated. Thank you.

  3. Hi Jiri, I don’t know why – but suddenly this comment I made for Mr. Truth re-appeared again. So I will copy it and re-paste it. Hopefully this will not be too much diskursens for other readers. In this re-paste I will remove a link I made to a different website – perhaps that’s why the technology refuse it? Not you or anyone else – just for the security reasons on your website. I don’t know. This is only to inform you – no need to reply to it.

    Since the cars have not yet reached the international market where WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is commonly used, I suppose no tests has been carried out according to this standard. Although the WLTP tests will never be 100% correct, as in real life – they use better average criteria.

    USA (Canada) also have it’s own, called EPA, estimated range test, based on the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HWFET).
    They are normally stricter than WLTP.

    The former NEDC (New European Driving Cycle) was so faulty, therefor hardly/never used anymore. The CLTC – was developed by China Automotive Technology & Research Center (CATARC) in 2020, and you can read more about here: xxxxxxxxxxxxxxxxx (link removed).

    CLTC is based more on city traffic, lower speeds, etc., as that is the more normal situation in China – according to journalists. If you want generally close to real tests – there are two websites; motor.no and elbil24.no – where test on all EV’s available in Norway (Europe) – including also many Chinese – have been tested in both summer and winter conditions, and compared. These tests are often used as serious samples by international media.

    I hope this reply contain the information you’re looking for.”
