The new regulation coming into force in the United States aims to ensure that car manufacturers describe the real performance of their vehicles in their marketing.
Electric car manufacturer Tesla has lowered the estimate of the range of its vehicles, i.e. the operational radius, as the US authorities tighten the regulations related to vehicle testing. The new regulation aims to ensure that car manufacturers describe the real performance of vehicles in their marketing.
According to the Reuters news agency, Tesla has recently lowered the range estimates for several of its X-, S-, Y-, and 3-series vehicles. Reuters compared estimates currently reported in marketing material on Tesla's website with archived versions of the pages and figures reported on the website of US authorities.
For example, the range of the Y-series Long Range model is now estimated to be 310 miles or about 500 kilometers on Tesla's website. In the listing maintained by the US Environmental Protection Agency EPA, the range of the same car is said to be 330 miles, or about 530 kilometers, according to Reuters. Also with Tesla's Finnish speakers on the pages The range of the Long Range model is stated to be more than 530 kilometers.
of the EPA the new rules require car manufacturers to test the range and fuel efficiency of electric cars in the so-called default driving mode. It refers to the state the car is in when the driver starts it for the first time. Many modern cars have different driving modes that can be used to adjust, for example, the efficiency of the vehicle.
If there is no such default driving mode, EPA requires that the range be tested during the most efficient and least efficient driving mode and report the average of the results. The testing rules will come into force in such a way that they apply to car models of 2024.
Automakers conduct their own tests to determine range estimates for marketing, but must follow EPA guidelines, Reuters reports. The EPA, in turn, retests a certain number of vehicles to ensure that the manufacturers' estimates are accurate.
Tesla did not respond to Reuters' request for an interview regarding the lowering of range estimates or the EPA's new testing rules.
Reuters reports in July, that Tesla has deliberately exaggerated the operating range of its cars. According to the news agency, Tesla started tampering with its range-predicting software about a decade ago for marketing reasons. The company wanted to show its drivers “rosy” travel forecasts when the car's battery was full.
