Edmunds It did more than make big waves in the media when its real-world electric vehicle range tests revealed that no Tesla could match its EPA rank. He got Tesla to contact him, something that hasn’t happened very often since the company killed off his public relations department. Tesla questioned the results, arguing that the cars should run until they could no longer move. Edmunds accepted the challenge and carried out new tests on a track. Tesla will hate the results.
The automaker’s main argument was that there is a battery buffer that should have been considered to reach the EPA range. Since that buffer is also present in other vehicles, Edmunds He also took them to the test track in the Mohave Desert. All cars were driven by all test drivers at the same temperatures.
In addition to a Model Y Performance, a Model 3 Standard Range Plus and a Model 3 Long Range, Edmunds It also put a VW ID.4 First Edition and a Ford Mustang Mach-E AWD Extended Range to the test.
The test consisted of driving all the cars at 65 mph (105 km / h) on a 7.5 mile long closed-loop oval. When these cars reached zero charge, Edmunds He started counting how much more they could run on the battery buffer at the set speed. When they could no longer run at 65 mph, they were driven until they could no longer move.
Tesla vehicles go 10.3 to 22 more miles after reaching zero charge on the dashboard below 65 miles. It was the three EVs with the most range remaining after that point. When electric vehicles could no longer maintain that speed, the Model Y Performance lost its place in the rankings to the ID.4. While the VW ran 12.9 miles, the Model Y ran 12.6 miles.
Although those are interesting numbers, Edmunds They had to be added to what the vehicles had achieved on the track.
Only one of the Teslas tested in the Mohave Desert was able to achieve its EPA ranges. It was the Model 3 Long Range, which hit 343 miles. Its official EPA range is 353 miles, which is sure to sound strange. Technically speaking, he did not reach his official rank. Edmunds you must have found a percentage difference acceptable to say yes.
The others wouldn’t get there even if Edmunds He counted the buffer and was forgiving of his numbers. Doing that, the Model Y Performance would achieve 263 miles of range against an EPA range of 291 miles. The Model 3 Standard Range Plus would hit 232 miles instead of the 250 that its EPA range promises. Although the Model 3 Performance wasn’t on the test track, it would get 256 miles, much less compared to its EPA number of 310 miles.
To further complicate things, Edmunds brought the Model Y Performance and Model 3 Long Range to its real-world EV range test circuit, and the cars run even less than on the track after reaching zero load and coming to a stop. It should be the opposite.
According to what Tesla engineers said Edmunds, your cars don’t have a defined buffer, which is a factor to consider in this case. We have already mentioned that Tesla runs on a virtual battery buffer on April 13, 2020. The others would be ambient temperature, driving style, and instantaneous conditions. The only part that makes sense is the variable buffer.
As Alistair Weaver emphasizes in the video, what this shows is that government figures alone cannot be trusted. We have gone even further than Edmunds‘editor-in-chief when we recommend that electric vehicles have specific test rules that take them into consideration and can determine how energy efficient they really are.
