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.

Audi plans to give its electric vehicles looks that differentiate them from the rest of the lineup. "In early 2018, we will launch a battery-powered sports activity vehicle in the large premium segment with a range of more than 500 kilometers," says Audi's head of development, Ulrich Hackenberg. "It will have a new, very attractive design, which we are developing especially for the E-Tron range and for battery-electric vehicles." According to analysts, part of the reason the Toyota Prius was so successful was because it was easy to distinguish from other Toyota models with conventional powertrains.

James Lawler used mostly scraps to build the tiny house – complete with tin roof, chimney, and stained glass window – for just $150 Australian. It took him about a week to finish. Lawler made use of his creation at the Meredith Music Festival so he didn't have to sleep in a tent. He was, however, fined by police for driving the makeshift motorhome.

Recharge Wrap-up: Georgia gets E15, new PSA EVs will be cheaper and offer more range

What would it be like to test drive a gasoline-powered car in an EV-dominated world? A post by Tibor Blomhall at Tesla Club Sweden gives a glimpse into this alternate universe. The review begins by noticing the pushiness of the dealer at the "repair shop" that sells the car, which is cause for suspicion - a clear nod to Tesla's lack of such franchise dealerships. Of course, the author mentions the noise, vibration and the smell of the exhaust. He notes the inefficiency of the idling vehicle and its less-than-smooth operation, particularly when it comes to changing gears. The one plus: refueling is quick. The downsides, though, are that the fuel is toxic, dangerous and expensive, and you can't refuel at home. "Imagine if you could charge your electric car only at the power companies' most expensive fast chargers - and nowhere else!" Read more at Tesla Club Sweden.
