The EPA carried out autonomy tests on the Tesla brand Model S and contrary to the messages hammered by the brand, its model would not reach 400 miles (644 Km) of autonomy. According to experience, the agency reveals that the autonomy of the vehicle reached 391 miles, a figure lower than that announced.

Elon Musk reacted by indicating that the agency had not carried out the tests in optimal conditions, that it had left a door open and the keys inside during the stop, thus pushing the car to go into mode "Waiting driver" and consuming more energy. According to him, this oversight would have resulted in a loss of autonomy of 2%.

However, the response was quick and the agency maintains that the test conditions were normal and that no doors were left open. " We can confirm that the EPA has properly tested the vehicle, that the door is closed, and we would be happy to be able to discuss any technical issues with Tesla, as we do regularly with all automakers. "Says the agency

A lower autonomy than that announced and a very competitive market

The EPA has estimated the range of the Model S at 391 miles. In other words, the brand would have slightly overestimated the autonomy of its vehicle to face other models on the market.

In this very competitive market, the symbolic bar of 400 miles of autonomy is indeed very important. The other major players in the sector achieve results greater than or equivalent to this distance. Among them the Lucid Air reaches 400 miles on the road and the Model 3 of Xpeng which reaches 706 km.

When Tesla announced the results, Elon Musk said he would like to re-test with the EPA as soon as the pandemic restrictions are lifted.
