Obviously you didn't read (the first sentence of) the article, I applaud your courage in commenting regardless.

The 1044km claim is from a livestream where the CEO of the company drove the car from Shanghai to Xiamen until there's 3% left in the battery. All this amid a cold wave too.

> The temperature during the test was between -2 °C and 12 °C (28 – 54 °F). The coldest time was at the beginning of the test, as it was early morning in Shanghai. The average cabin temperature was 20 °C (68 °F). The carload was about 190 kg (two adults, lifestream equipment, and other items).

Yeah CEOs are well known for their unbiased claims about their own companies, much more so than standards bodies (however flawed)

How can you bias a livestream where you drive the number of kilometers that you later claim that you can drive with the car? You can at worst commit outright fraud, but bias?

Hypermiling is a known method for extending the range. That is why standardized tests are important so you can match the standardized number to your driving.

A livestream is hard to fake but what tires were they using? What was the climate control setting? What speed? Did they have a tail wind?

  The maximum speed was caped to 90 km/hour (56 miles/hour), and the energy consumption was 13.2 kWh/100 km. The average speed for the trip was 83.9 km/h.
so there it goes, driven at an average speed of 53 mph hypermilling! For comparison, Tesla M3 achieved 975km:

  In May 2018, Sean Mitchell and Erik Strait set a hypermiling record for the Tesla Model 3 by driving 606.2 miles on a single charge after 32 hours of driving.

For comparison, the Tesla Model 3 was travelling at an average of 18.94 mph

Sure, the M3 also has 1/3 less battery capacity too.

They give you most of that information in the article.

Well, Tesla did exactly that, they faked a full autopilot demo:

And they clearly can use a rigged car, cherrypick conditions etc. If it even were live.

So fraud, not bias

Sure but it depends on the location. I guess in China fraud committed by a company with strong party connections (as all companies have) is not illegal. Otherwise half the alibaba sellers would be arrested :) :)

But I generally don't like to throw legal terms around unless it's been proven in court.
