Tesla Model S Fails To Get Top IIHS Crash Rating

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."
