Tesla Model S Fails To Get Top IIHS Crash Rating (usatoday.com) 80

mrspoonsi writes: Shares in Tesla have plummeted more than 13 percent this week after lower than expected deliveries and the Model S only attaining an acceptable result in recent crash tests. The Insurance Institute for Highway Safety states: "Tesla made changes to the safety belt in vehicles built after January with the intent of reducing the dummy's forward movement. However, when IIHS tested the modified Model S, the same problem occurred, and the rating didn't change. Although the two tested vehicles had identical structure, the second test resulted in greater intrusion into the driver's space because the left front wheel movement wasn't consistent. Maximum intrusion increased from less than 2 inches to 11 inches in the lower part and to 5 inches at the instrument panel in the second test. The first test resulted in a good rating for structural integrity, while the second test resulted in an acceptable structural rating. The two tests' structural ratings were combined, resulting in acceptable structure and an acceptable rating overall for the Model S." A Tesla spokesperson responded to the IIHS's crash rating in a statement to Forbes: "IIHS and dozens of other private industry groups around the world have methods and motivations that suit their own subjective purposes."

    yep driver and passenger safety, obviously Telsa's motivations differ significantly.

      Forbes truncated their quote (and worse, added in a period to make it look like that ended a sentence). The actual quote is:

      Tesla's Model S received the highest rating in IIHS's crash testing in every category except for one, the small overlap front crash test, where it received the second highest rating available. While IIHS and dozens of other private industry groups around the world have methods and motivations that suit their own subjective purposes, the most objective and accurate independent testing of vehicle safety is currently done by the U.S. government, which found Model S and Model X to be the two cars with the lowest probability of injury of any cars that it has ever tested, making them the safest cars in history.

      The quote appears deliberately truncated to try to make it look like Tesla is badmouthing the IIHS, when they're very clearly just saying that they think the NHTSA testing is more meaningful. While that's a debatable point (I see no realistic reason to favour one over the other), Forbes' truncation is pretty questionable. Of course, what do you expect from an opinion piece that in its second sentence all but calls Tesla a cult?

      The reality is that the failed test ("small overlap") is a new test developed in 2012, after the Model S design was already completed; it was never designed to the test, only adapted to try to meet it (apparently unsuccessfully thusfar). To be fair to Tesla, this same issue has hit numerous other manufacturers; only three vehicles at present pass get the best rating in it (two of them new designs from 2017) - and Tesla did manage the second best rating. On the other hand, Tesla wants to build part of its reputation on being a leader in safety, and the small overlap crash test, while new, is meaningful. It's the equivalent of sideswiping a utility pole or similar - a very real type of crash that has previously not been well represented in existing crash tests. Tesla needs to get this right next year.

      • There is this saying as old as the auto industry that the most critical safety component of any car is "the nut behind the wheel."

        This crash safety tests are fine, and IIHS is trying to make them more fine, but they publish interesting (if not macabre) data on vehicle death rates that don't strictly correlate with the crash-test ratings.

        • My observations are that minivan drivers are some of the worst on the road, usually because they are driven by inattentive and distracted soccer moms who aren't particularly good at driving such a large vehicle in the first place. Though this is changing because minivans aren't the favored mommy-mobiles that they used to be.

          I can believe them being safer though, as minivans (especially newer models) have considerable bulk and mass, and since they have a lower center of gravity, they don't have the same rol

        The NHTSA tests were made by a bunch of people sitting in an office thinking up what might be a good way to simulate vehicle crashes to test their safety.

        The IIHS tests are made by the folks who have to pay out money for insurance claims, and are designed to weed out failure modes they are seeing in actual crashes which led them to pay out more than they were expecting. They made the driver's side overlap tests specifically because they saw it as a weakness with the NHTSA tests. The NHTSA test only covers impacts directly from the front and the side. Yet they were seeing a lot of claims from impacts where cars didn't hit head-on and the intrusion thus bypassed most or all the crash-resistance designed to satisfy the NHTSA test.
        • Driver drifts slightly over the double yellow line and hits a car in the oncoming lane.
        • Driver veers off the road and hits something (concrete, building, etc) at an angle driver's side first.

        Those are the scenarios that the IIHS test is trying to replicate. Passing the "small" version of the overlap test successfully is important because if the car can't, it may actually be better for the driver to let a greater portion of the car's front hit the oncoming vehicle/obstacle, rather than to try to avoid it and only receive a glancing blow. As the size of the impact area shrinks, the stresses on the section receiving the impact increases because there's less material absorbing the same crash energy. So the crash-resistance should be concentrated mostly along the sides, tapering off as you move inwards (perhaps increasing again towards the center). That is what this test is encouraging car designers to do. A car could be designed to let its left or right side completely shear off in a collision which misses the center of the front bumper, and still be completely NHTSA-compliant.

      • If the small overlap test was invented in 2012, how did the Volvo s80 pass it in 2007? http://www.iihs.org/iihs/ratin... [iihs.org] click on "other model years" to see the test results through time.

          That's easy to explain based on the source you cite:
          For Small overlap front: "Tested vehicle 2014 Volvo S80 3.2 4-door" ( http://www.iihs.org/iihs/ratings/vehicle/v/volvo/s80-4-door-sedan/2007 )
          I guess they apply the same result to all preceding years during which the model was not altered.

    Does Tesla really need to be the best on crash safety? Last time I checked, their goal isn't to make the world's safest car. It's not enough to make a safe electric car, it has to be the safest car?

    • Yes they do. They may not be in the business of making the safest car, but part of their reputation now is based on this somewhat incidental claim to fame. The incidental part here being the different structural design that was primarily focused on the things that needed to sit in the frame.

      Worth noting is if you dig through the bullshit article they are STILL the king of safety and as noted above this test was introdu

          As a matter of interest how do you think this will be achieved in the face of "ANOTHER TESLA CAR BURSTS INTO FLAMES" headlines that they have been battling. You are right in their purpose, but given that the establishment is looking for absolutely any excuse to derail them and even making a few up as they go along, being "the best" even in such side themes as safety is solidly inline with their goal.

          It wasn't designed badly... They bought an industrial press to test how much pressure the roof of cars could withstand because people were getting crushed to death when they rolled. They bought one specified for every car on the market and then some, but Tesla made a car so ridiculously strong it exceeded the design limit.

    How many GM, Ford, Chrysler, Audi, BMW, VW or other cars have received that rating? GM hid a defect for about ten years, VAG cheated on Diesel emissions. Takata is going bankrupt over airbag defects, but Tesla is the bad guy here.

    Seems like the big guys don't want the new guy to succeed.

    • Toyota, Mercedes, and Lincon.

      3 cars have passed, all current models, none designed in 2011 like the Model S which we insist on holding to ridiculous standards.

    • Tesla really brought this upon themselves. They are the ones that decided to throw a temper-tantrum and attack the IIHS simply because they didn't award them a perfect rating. Nevermind that the Model S is still one of the safest cars out there according to the rating the IIHS did give it. I don't see GM, Ford, Chrysler, Audi, BMW, VW, etc. behaving like this when the IIHS gives them a rating they don't like.
