Investigators Find No Defect Trend With Tesla Motors' Model S

Federal safety investigators said Friday they have found no apparent defect trends in the Tesla Model S, an electric luxury car that has its share of fans and critics. The National Highway Traffic Safety Administration closed a four-month investigation into whether the car's batteries were at heightened risk for underbody strikes and subsequent fires. Even though no defect trend was found, Tesla Motors said in a written statement it would further protect the bottom of its cars with a reinforced underbody shield. The California-based automaker started adding the shields on March 6 and will retrofit older models free of charge. It will also increase the ground clearance of new cars. "This fix should eliminate the potential of a battery-pack fire under all but the most extreme circumstances," said Karl Brauer, a senior analyst at Kelley Blue Book. Although there are more than 194,000 car fires in the United States every year, NHTSA investigators began a preliminary investigation into potential trouble on Nov. 15, 2013 following two Model S fires, one in Tennessee and one in Washington. No one was injured or killed in either fire. Roadway debris punctured the battery pack near the front of the compartments in both cases, damaging the batteries' lithium ion cells that then began "thermal runaway" events. The opposite ends of the debris had dug into the pavement and jutted upward. Tesla called this a "piking effect." The company said it has conducted 152 vehicle level tests, and that the new shields prevented any damage or penetration of the new shields. The first is a rounded, hollow aluminum bar that's followed by a titanium plate. The third layer of protection is made of solid aluminum. (There's video of the new plates in action on the Tesla Motors website). "We have tried every worst-case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event," Tesla Motors founder Elon Musk wrote on the company's blog," essentially equivalent to driving a car at highway speed, into a steel spear braced on the tarmac." Approximately 15,805 vehicles are eligible for the upgrades, which NHTSA says should reduce the frequency of underbody strikes and subsequent fire risks. But the agency did note that the closing of the investigation did not necessarily constitute a finding that a defect does not exist. "The agency reserves the right to take further action if warranted by new circumstances," it said.

Tesla begins selling in China, despite lack of formal company name

Car buyers in China can now start shopping for a new Tesla Model S. Only problem is, the California-based automaker doesn't seem to have hammered down a brand name for that market. According to Reuters, Tesla is still dealing with a trademark squatter for "Tesla" (or "Te Si La"), so in the meantime, it is a brand without a name.
Tesla has launched a website in China under the Tousule name, but it doesn't appear that will be the official nomenclature for cars sold in China. According to the report, a Tesla salesman in Beijing doesn't know when - or even if - Tesla plans to come up with a Chinese name for its brand. We reached out to Tesla for a comment on the matter, but we've yet to receive any response regarding this ongoing situation in China.

Elon Musk hints at opening Tesla's EV patents [w/video]

During the Q&A portion of Tesla's annual shareholder meeting last week, CEO Elon Musk said something that caught our ear: "I'm contemplating doing something fairly significant on that front [promoting EVs] which should be kind of controversial with respect to Tesla's patents. But I probably want to write something so that I can take articulate it properly and explain the reasoning for the decision." We immediately asked Tesla for more information but it was the BBC that got to question Musk in person during the UK launch of the right-hand drive Model S (see press release and video below). "We don't want to cut a path through the jungle and then lay a bunch of landmines behind us" – Elon Musk The BBC asked Musk if his comment meant he was considering opening up Tesla's patents, and Musk responded with, "you're on the right track." A strong proponent of promoting EVs, Musk also said, "We don't want to cut a path through the jungle and then lay a bunch of landmines behind us." This wouldn't be the first time Musk has given away a big idea. His outlandish hyperloop high-speed train-like transportation system was open source from the get-go. Musk has also offered to let other automakers piggyback on Tesla's Supercharger fast-charging system. Musk's SpaceX company doesn't even file patents, but that's more to protect the ideas from the Chinese than to make getting to space an open source endeavor, Musk said. Tesla told AutoblogGreen it is offering "nothing further at this point" on the patent front, so we'll just have to guess away in the comments.
