Recently, it was reported that Li Bin, the founder of Weilai Automobile, drove **ET7 for a range test on December 17, 2023, and invited ** personnel to witness it together.
During the live broadcast, Li Bin suggested that the CEOs of major car companies should personally test the vehicle range and use it as the industry standard.
However, some people have questioned this, arguing that the suggestion may only be made because of Li Bin's work at NIO, and that the CEO of the company should not personally work as a test driver.
In addition, the speed of the vehicles during the live test was also controversial, as the test speed was only maintained between 80 and 90 km/h, and the speed limit on highways is usually much higher than that.
Is this move just "brushing battery life"?It is worth thinking deeply.
At the same time, we have also shared some trivia about the minimum speed limit of highway lanes, let's find out together.
Family cars generally travel at around 110 km/h on the highway, while many veteran drivers set their speed at 120 km/h.
The key to whether the NIO ET7's range test results are convincing lies in the top speed and the proportion of mileage driven at a high speed during the test.
There is no point in the CEO's personal testing, and the user's main concern is the real range.
The real cruising range should refer to the WLTC test mode, and there are three modes for the car fuel consumption, power consumption and range test: CLTC, NEDC and WLTC.
The CLTC cyclic mode has the most fluctuating results, with NEDC in the middle and WLTC being the closest to the real road modeBecause the test process includes high-speed and ultra-high-speed tests with a high proportion of time, the test has the highest energy consumption and the shortest cruising range.
Therefore, new energy vehicles do not need to be tested by the CEO in person, and only the mileage of the WLTC test can be announced.
At present, the range published by all brands of pure electric vehicles is the test value of the CLTC working condition, so the release of WLTC test results is more convincing than Xiucai.
