Tesla adds free titanium underbody shields to Model S to prevent fires

Following a garage fire incident with a Model S EV last year, Tesla Motors quickly sent out an over-the-air software update to adjust how the car charges. Following two on-road fires caused by road debris that struck the underside of different Model S EVs (one in Washington State and the other in Tennessee), Tesla basically said, that it was a random thing, and the car is perfectly safe. The company later sent out a software update to have the car ride a bit higher at highway speeds. Today, Tesla is offering a more substantial solution. Tesla CEO Elon Musk has announced that all Model S EVs built since March 6 have a stronger triple underbody shield that should "bring this [fire] risk down to virtually zero." The company conducted 152 tests using, "every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac" and is now confident that there's basically nothing that can break through the new barriers. As you can see here, the shields prevent a concrete block, a three ball tow hitch and a steel alternator from puncturing the car's underside. The new shields should "bring this [fire] risk down to virtually zero." Any Model S owner who wants the new triple shield can ask for it, and even if they don't ask, the structure will be installed whenever the car is next in for service. The three layers of the shield include a rounded, hollow aluminum bar, a titanium plate and "a shallow angle, solid aluminum extrusion." The new shields, "only have a 0.1 percent impact on range and don't affect ride or handling," Musk writes, which means there's no reason for Model S owners not to get the upgrade. You can read all of Musk's explanation below. Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S By Elon Musk, Chairman, Product Architect & CEO In 2013, two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit the vehicles, which they did well before any fire was noticeable.

Norwegian winter proving too much for some Tesla charging cables

Polar vortex 1, Tesla Model S 0? Possibly. Norway is certainly a long way from the sunny California climes where the luxury electric vehicle is made and, while the cars are popular in that country, the country's cold weather is creating problems for car owners, the Norwegian website News in English reports. As winter has set in, a number of Model S owners are reporting charging problems. One driver was stranded with a dead battery on Christmas Eve, while others have said Tesla's recharging cables are having a hard time holding a charge when the temperature gets substantially below freezing levels. Tesla has acknowledged that Norway has a different kind of electric grid than the US (and not just because it's 99 percent hydro-powered) that could be causing the problem. The company has reportedly sent Norwegian owners country-specific updates for the on-board recharging software. Once charged, the Model S works just fine in Norway. In this December video, posted by Norwegian Model S owner Bjorn Nyland, a Model S manages to drive for about 233 miles on a single charge in temperatures that reached only about 21 degrees Fahrenheit, and even then the car had about another 25 miles worth of juice left. Tesla has been well-received in Norway in part because of extensive government incentives as well as perks such as bus-lane access and free parking.
