9 miles short of target: EPA denies wrongdoing in Model S range test

Tesla CEO Elon Musk said the Model S long-range version made a mistake in testing, according tomedia reports, and the U.S. Environmental Protection Agency (EPA) declined to comment on the matter because the missteps caused the vehicle to miss the 400-mile range previously promised. But the agency told Roadshow that their tests were not wrong.

9 miles short of target: EPA denies wrongdoing in Model S range test

Let’s review. On Tesla’s first-quarter investor conference call this week, Musk said the Model S should have a range of 400 miles, compared with 391 miles by the EPA.

Why is that? At some point during the test, someone left the keys in the car overnight and the doors remained open, the CEO revealed. In this case, the Model S goes into “waiting driver” mode, which causes the electric car to consume 2% of its range, resulting in a value of less than 400 miles. Musk added that the company plans to retest the Model S with the EPA and is confident that the new test will allow it to reach 400 miles.

However, an EPA spokesman told Roadshow that there was no problem with their testing process, the doors were closed and they were willing to talk to Tesla about any technical issues.

For now, the 391-mile figure still meets EPA standards. To its credit, it remains the highest range rating of any electric car on the market today, with a mouth-watering 400-mile target of just nine miles.

If the retest does happen and confirms Musk’s prediction, Tesla will be the first company to sell an electric car with a range of 400 miles.
