What to do if you run out of juice in your Tesla Model S

After writing about their Tesla Model S running out of juice on the side of the road between Las Vegas and Barstow, CA recently (read about it here), the fine folks at Teslarati figured they had some 'splainin' to do. The brief explanation is headwinds. Yes, headwinds. A Model S has about 10 miles of range even after it shows a big fat "0" on its dash. Thankfully, the drivers took notes about what to do if your Model S is about to shut down like C-3PO in A New Hope. Step one is to know that the EV has about 10 miles of range (maybe 20) even after it shows "0" on its dash. Once that distance is used up, it's time to pull the car over, and even then there is enough reserve juice to power the screen for a half hour. After that, all that works are the door handles and the flashers. So, before everything goes completely dark, it's best to remember to put the car into "tow mode" and get it into neutral so that the EV doesn't have to be jumpstarted just to get it onto a truck. Also, once the Model S has been recharged from empty, it needs to be powered off in order to reset the system and not keep it in "depleted power" mode. Now you know. The way Teslarati learned all of this was that, after using a Las Vegas supercharger to give their Tesla Model what they thought would be about 240 miles worth of range for the 160-mile drive, the car unfortunately provided them with just 157 before shutting down. The culprit was a sand storm that sent 35-mile-per-hour headwinds (and probably a bit of grit) into the car as it maintained a 75-mph cruising speed. Teslarati also said elevation changes were part of the problem. Las Vegas and Barstow are both about 2,200 feet above sea level, but there are a bunch of hills in between, and we guess the declines giveth less then the inclines taketh away. Happens to the best of us.

Tesla Model S owners hack their cars, find Ubuntu

There are interesting subsets within the group of people that composes Tesla Model S owners. They include celebrities, Drudge Report-reading conservatives, and, more relevant to this post, tech-savvy geeks. Now, give that last bunch an electric car with an easily-exposed Ethernet connecter and they will try to plug into it and snoop around. Don't believe us? Well, several have already admitted to giving it a try on this thread over at the Tesla Motors Club forum. After wiring into the car's communications system, forum user "nlc" was able to find a number of ports and tap into the data flowing to the center console and navigation screens. Others soon joined in the fun and amongst the slightly esoteric bits of information the "hackers" eventually discovered was that the sub-system runs on a version of Ubuntu operating system, which is a Linux variant. While one person did manage to use the discoveries to get Firefox to display on the center console touchscreen (sideways), it doesn't seem likely anyone will be able to do more invasive things with the Ethernet entry point like, for example, transform an early 40-kWh Model S into a 60-kWh version (you can't hack extra batteries). For those who want to customize the big 17-inch display, or at least get it to play video, it seems they'll be better off waiting until Tesla is ready to release the software development kit (SDK) it has promised for third-party app builders. For its part, the California automaker isn't particularly thrilled to have its customers digging beneath the dash. Through its service center, it has already contacted the original Ethernet exploiter to let him know they were aware of his actions and that such activity could lead to a voiding of the warranty. Indeed, the Motor Vehicle Purchase Agreement (MVPA) which buyers sign does contain a clause which reads, in part, You may not, or may not attempt to, reverse engineer, disassemble, decompile, tamper with or engage in any similar activity in respect of a Tesla Vehicle, nor may you permit any third party to do so, save only to the extent permitted by applicable law. It could be argued that this light-handed geekery doesn't quite measure up to the legal extent permitted, but we know if we owned a car that costs as much as $100,000, we wouldn't be risking it. Not when there are salvage-titled cars out there on which to practice the black arts.

Tesla Roadster 3.0 package prototype announced with 400-mile possibilities

Once a car company ceases to manufacture a particular model, it is relegated to history, largely forgotten by its maker. Sure, warranties are honored and recall-worthy items are (hopefully) taken responsibility for, but post-production improvements are left up owners and the aftermarket. With the announcement of the Roadster 3.0 package, Tesla once again reminds us it is not most car companies. Following a heads-up given by CEO Elon Musk last week on Twitter, the company has now shared some details of a new upgrade it will be making available for its electric sports coupe sometime in 2015. For a yet-to-be-disclosed price, owners can opt to have their cars upgraded with a 70-kWh battery, some aerodynamically-optimized body bits and low-rolling resistance tires. Together, the enhancements should offer a 40-50 percent range improvement and give Roadsters a 400-mile range under certain conditions. Originally, it came with a 56-kWh unit and was rated for 245 miles on a charge. Tesla tells us that "this is a retrofit package currently in its prototype phase", and so it still isn't clear whether the changes will allow Roadsters to be compatible with the Supercharger network, or whether the body kit will affect the outward appearance. We do know that this automotive augmentation does not also apply to the Model S, though it does give hope that those cars will also be on the receiving end of similar upgrades in the future. The California company plans to put its 3.0 package to the test sometime early in the new year, with a road trip from San Francisco to Los Angeles. Interestingly, it says that this will not be the last time it offers improvements for its original model. You can get more details on the update below. Roadster 3.0 The Roadster 3.0 package applies what we've learned in Model S to Roadster. No new Model S battery pack or major range upgrade is expected in the near term. Battery technology has continued a steady improvement in recent years, as has our experience in optimizing total vehicle efficiency through Model S development. We have long been excited to apply our learning back to our first vehicle, and are thrilled to do just that with the prototype Roadster 3.0 package. It consists of three main improvement areas. 1. Batteries The original Roadster battery was the very first lithium ion battery put into production in any vehicle. It was state of the art in 2008, but cell technology has improved substantially since then.
