Tesla’s decision to drop radar costs it two “top pick” ratings

New York (CNN Business)Tesla’s best-selling Model 3 sedan lost two designations from Consumer Reports after the company made changes to the car’s automatic braking and front collision warning systems.

The car also was stripped of its designation as Top Safety Pick+ from the Insurance Institute for Highway Safety.The moves came after Tesla announced that, as of May 1, its Model 3 and Model Y SUVs replaced the radar based system it used to detect obstacles with a camera-based system it dubbed “Tesla Vision.”

    “These will be the first Tesla vehicles to rely on camera vision and neural net processing to deliver Autopilot, full-self driving and certain active safety features,” said a statement that Tesla posted on its website. Tesla did not respond to a request for comment about the changed ratings designations.

      The change in technology prompted the US federal safety regulator, the National Highway Traffic Safety Administration, to drop the cars’ listing as having automatic braking or a front collision warning system. And that, in turn, prompted Consumer Reports to change its rating on the Model 3.Read More”To be considered for a Consumer Reports Top Pick, a vehicle must be recommended and have standard front collision warning and automatic emergency braking with pedestrian detection,” said Consumer Reports in a posting on its site. Without those features the Model 3’s overall score dropped to 75 from 78, although it retained its “recommended” status. The Tesla Model Y—which was not a recommended vehicle—drops from 50 to 47.Jake Fisher, senior director of Consumer Reports’ Auto Test Center, said he was surprised that Tesla would do away with the radar. “In general, more sensors are more helpful,” he told CNN. “But I cannot make a judgment as to whether this is better or worse.”He said it is disappointing and unusual for an automaker to drop a safety feature. “I don’t understand why they would, unless it’s another reason, like parts availability,” he said.Many automakers, including Tesla, have been struggling to get enough computer chips to build their cars.

      Tesla seems to change its mind on cameras monitoring drivers while using AutopilotFisher said the change by the federal agency prompted Consumer Reports’ actions, not any of its own testing. “NHTSA only includes check marks for the technologies on a vehicle model that have been either verified by NHTSA or reported by the vehicle manufacturers as meeting NHTSA’s performance criteria,” said a statement from NHTSA about its action. “We removed the check mark because we have no test results for Tesla’s recent changes.”

        The IIHS said it plans to conduct tests soon on the new camera-only system, and that it is possible it will restore the rating. “Tesla informed us directly of the changes they were planning, and we let them know we’d need to test the camera-only system before extending the Top Safety Pick+ award to vehicles with that system,” said IIHS spokesman Joseph Young. It still lists the earlier versions of the Model 3 as a Top Safety Pick+. It has no rating on the Model Y.
