EPA Denies Elon Musk's Claims Over Tesla Model S Range Test (cnet.com) 80

The Environmental Protection Agency has rebuffed comments Tesla CEO Elon Musk made concerning what he calls an error during the Model S Long Range's testing process, which the executive says cost the car a 400-mile range estimate. The agency tells Roadshow it conducted the testing properly. CNET reports: During Tesla's Q1 investor call this week -- which also included some colorful language surrounding stay-at-home orders during the coronavirus pandemic -- Musk said the Model S Long Range should boast a 400-mile range estimate, but instead, the EPA gave it a 391-mile estimate. Why? According to the CEO, at some point during the testing process, someone left the keys inside the car and the door open overnight. The Model S entered a "waiting for driver" mode, which depleted 2% of the EV's range, hence the sub-400-mile rating. Musk added that the company plans to retest the Model S with the EPA and is "confident" the test will produce a 400-mile car.

The automaker did not return Roadshow's request for comment on the situation, but an EPA spokesperson said in a statement, "We can confirm that EPA tested the vehicle properly, the door was closed, and we are happy to discuss any technical issues with Tesla, as we do routinely with all automakers." It could very well be that Tesla estimates show the Model S Long Range returns a 400-mile range, but for now, the 391-mile estimate sticks with the EPA. To Tesla's credit, that's still the highest range rating of any electric car currently on the market, and just nine miles off the coveted 400-mile mark.

      In reality, less than nothing, it is already old tech. Readily replaceable batteries is the new tech. Drop into a battery service station and in a couple of minutes have your flat batteries replaced with fully charged batteries and never concern yourself with old batteries again but definitely go to dealer service stations to avoid shit batteries, otherwise you will be buying your next set to swap.

      • Readily available batteries? Service stations?

        So you really think that car-manufacturers are going to standardize the battery-packs and miss on the opportunity for vendor lock-in?

      • Readily replaceable batteries is the new tech.

        Swappable batteries are not a new idea.

        They have been tried but it doesn't work because someone who just paid $30,000 for a brand new 400-mile battery isn't willing to exchange it for a crappy ten-year-old battery that has lost 30% of its capacity.

        Swapping was developed furthest by Better Place [wikipedia.org], an Israeli company that went bankrupt in 2013.

        With super-charging times down to about 20 minutes for 80% capacity, battery swapping is dead.

        • NIO in China is forging ahead with battery swap, they are putting the swap station right next the chargers. For the life of me i can't remember who, but someone is allowing/contemplating a temporary swap for a bigger battery for a longer trip.

          I don't think its practical in the long run

      9 mile range

    • "9"

    • What's the range of the car when the batteries are a year it two old?

      • by olddoc ( 152678 )
        Based on my 5 years of Tesla ownership with a Model S, an X and a 3, I'd expect at most a 3% drop to 380 miles. This is assuming reasonable use and rarely charging over 90% capacity. In real life, you would charge the car routinely to 90% at most. This would indicate 360 miles of range. If you were in the USA and making a long trip on a 70mph highway and you kept up with traffic and drove 80mph you could drive ~280 miles before you ran out. That's 3 1/2 hours of high speed driving before you need a charge.
        • So when it is -40C out and I'm driving on the highway and have to crank the heat, I can't even charge to 100% to get the full 150km range that I have left?
        • by Malc ( 1751 )

          Interesting. Basically that means quibbling over 9 miles to get the marketting win of a 400 mile range is actually bullshit. Nobody will practically ever experience that range.

    • You can't tell without knowing the accuracy of the measurement.
    • You mean the difference between 629 km and 644 km? :)

    Setting aside the fact that judging by his Tweets, Elon's mental condition appears to be... frayed?

    From a technical perspective, Tesla has been known to keep detailed logs of cars that they are interested in monitoring. If the door was open, I assume they have logs confirming it. Sure, it could be a bad sensor, but I doubt the EPA is going on much beyond the technician had a vague recollection that the door was closed. If you put a gun to my head, I'd sooner trust Tesla on this one, Elon's bizarre behavior notwithstanding.

    • Absolutely. I trust a log made by a computer over a government agency that has reputation to lose.

    • Yes, on this I would think Musk would be the one to be right.

    • Yes, doomsayer, Elon's so impaired he might only be 267% the thinker you are... so glad he's the one in position to influence the outcome of humanity.

    • by Burdell ( 228580 )

      Tesla is logging actions in all of their cars? And people don't think that's a massive invasion of privacy? Unless you are going to say it is opt-in AND the EPA opted-in during testing (which would seem odd); even having the ability is a huge invasion of privacy waiting to happen (because you have to just hope and trust that "opt-out" really is).

      Also: if 391 miles is missing 2%, that would mean the real range is 399 miles; still not a 400 mile car (if 9 miles matter, so does 1).

        It seems to be opt-in but for a car given to EPA for testing I am sure Tesla did turn it on: manual [tesla.com] page 214

      I would imagine that there was some tradeoffs made and careful design that went into getting to a 400-mile range. Sure it's an arbitrary number, but there is a little bit of a psychological effect at play. I think they reason Musk is pissed is because they missed the target and when they reviewed the logs they found out it was due to someone else's fuck up and then to have the paper pushers deny it likely irks him to no end. Musk takes a lot of pride in his companies and their accomplishments and I'd probably be similarly pissed if I were in his position.

      If he were the kind of guy that didn't care about something like this he wouldn't have made a 400 mile range EV because he'd have just said "Fuck it, good enough" some number of miles well before that point.
      • by AmiMoJo ( 196126 )

        It's not really a 400 mile EV anyway. I mean you could do 400 miles if you drive very carefully, but if you just jump on the highway and cruise at 70 you won't get anything like that. So it's an arbitrary number anyway.

        It's also kinda pointless. If you actually could get 400 miles at 70 MPG average that would be 5.7 hours on the road. That's illegal for commercial drivers in Europe and you would do well to stop for a 30 minute charge every few hours anyway. The Model S isn't the most comfortable of cars eit

        • I just want to know the worst case, and it seems terribly elusive. When it is -40C and I have the heat cranked on the highway and I drive into desolate northern Canada where it is even hard to find a gas station, what am I in for?
          • by hawk ( 1151 )

        • It's not really a 400 mile EV anyway.

          Sure it is, just like my vehicle is rated to get 40 MPG by the EPA. Of course it's based on speeds that I don't drive, so I never realistically get fuel economy that good. I have no doubt that if I did limit myself to those constraints that I would get my advertised number. If the test conditions aren't realistic, that's the fault of the EPA and policy makers. All manufacturers are required to use them so though so there's no incentive for other ratings agencies to organize and use more reasonable measureme

          It is stupid anyway. A 400 mile endurance means a range of 200 miles. Range implies "out and back" and always has.

    We already know how these things turn out after past disputes over what actually occurred during other Tesla vehicle trials. Tesla vehicles log everything and transfer logs back to Tesla headquarters servers. Musk has the vehicle logs for the vehicle under test. If Musk says the keys were in the car and the door open overnight, then that's really what happened and the EPA is lying.

    Here [theguardian.com] is Musk debunking lies which the New York Times printed when it reviewed a Model S.

      Tesla is known to lie and use "logs" (which it never publishes) as fake evidence. They do that a lot when there is an accident involving autopilot, for example. When NHTSA looked at autopilot crashes Tesla made claims based on logs that they later found to be false, for example.

      Journalists have been discovered lying too of course, my point here is that we can't trust either of them and should wait for the re-test. Tesla, like all manufacturers, were probably cheating anyway. Cherry picked car with manually tweaked tolerances, the most efficient tyres, maybe strip some stuff out of the vehicle to reduce weight etc.

      • Tesla is known to lie and use "logs" (which it never publishes) as fake evidence.

        Nope. Tesla hasn't lied about their logs. They may have omitted truths and logs may not show the full details, but their logs have always reflected the recorded reality of what happened when filed.

        What the NHTSA has determined in some cases is that the logs had erroneous records due to recording in faith faulty sensors. But no lying of false reports. I mean if what you said were even remotely correct there would be several Tesla people in jail right now. Can you name them?

        • by AmiMoJo ( 196126 )

          If Tesla want to have any credibility they need to release the unedited logs.

          Like for example they say the door was open. Well was it, or was the senor faulty, or are they just making it up? Cry wolf so many times and the burden of proof goes up.

          Even then the logs need to be carefully interpreted. For example not detecting hands on the wheel doesn't mean hands are not on the wheel.

      • by Jodka ( 520060 )

        Tesla is known to lie and use "logs" (which it never publishes) as fake evidence.

        No, in fact, not at all.

        1. The parent post provides zero evidence supporting its allegation that Tesla is known to lie about logs. Because it is allegedly "known to", one would expect at least a single link to someone anywhere on the internet claiming to know that. But there is no such link provided, and the reason for that is:

        2. A Google search [google.com] shows absolutely no such allegations anywhere on the entire internet.. (Except perhaps the trivial self-referential one.)

        3. If Tesla never publishes the logs, as

  • ... tells that this car range is more than 600km
  • It's interesting, i would think that for scientific practices, invitations to repeat an experiment should be welcomed, as long as whomever is proven wrong foots the bill, or a penalty if Tesla's logs were incorrect. Merely insisting that the EPA did things correctly (considering the recent weird results on the Taycan) and sticking with their guns seems very unreasonable. They should be prepared to defend their findings should errors be documented, if they intend to portray their processes as scientific.
  • The truth will be in the middle. Maybe I'm too easy to believe that "nobody is lying", but when Elon says they left the keys in the car and the door open, I think the truth is that: The car's telemetry shows that it detected the keys near the car and the door open.

    When EPA says they closed the door, I'd think that the driver doing the test probably THOUGHT they closed the door. Possibly the keys were close enough to be detected in-or-near the car.
