Recently, an interesting study was published by Consumer Reports on the real autonomy of electric vehicles and comparison with the declared range of the EPA (the American agency that has formed the rules for the test cycle).
The main “highlight” is that the ERA cycle provides for a combined cycle of movement – that is, city/highway – but the Consumer Reports study demonstrates the range in conditions of driving on a highway: they say that these are the worst driving conditions for an electric car. And this study showed very interesting results…
For example, Mercedes and BMW’s electric cars significantly exceeded the stated figures, which means that traditional car manufacturers have already learned how to create good electric cars. And here’s the opposite result: the anti-record holder of the rating was the Ford F-150 Lightning pickup truck; however, Tesla and Lucid models also fell far short, i.e., representatives of “electric vehicles from birth.”
However, the Tesla Model S and Lucid Air were originally claimed to have very high autonomy, so the difference, even in the negative, still made them almost winners. Almost – because the absolute record holder was again a representative of a German company: the Mercedes EQS electric sedan!
Other observations included electric cars from Genesis, Hyundai, Kia, Nissan, Volkswagen, and others. However, there were no radical sensations here.
There are also some questions about the format of the study: the different electric cars were driven from 2,000 to 15,000 miles (a very big difference!); the speed was kept at 70 mph (113 km/h) and the runs took place in good weather; however, in temperatures between 20 and about 30 degrees Celsius – that is, this could also affect the battery performance or require the air conditioner to be turned on, which reduces the range. And add real traffic on the highway, “air bags” behind the trucks, etc. But one thing is for sure, it was very interesting!
