Tesla Model S EVs now come with lane departure, speed assist AI

When a car's built on such a technology-heavy platform like the one used by Tesla Motors, there are going to be a lot of bells and whistles. More of those little "noisemakers" are being rolled out, as previewed by a new software update. What's most interesting to anyone paying close attention to the slow evolution of the Model S is that the new features are not going to be possible without new components. Tesla Model S sedans will likely need a new camera mounted on the front mirror, but it's not for selfies. Instead, it's there to keep the driver from having too much of a lead foot or straying into another lane thanks to the electric vehicle's software and hardware update that adds Lane Departure Warning and Speed Assist. Other luxury vehicles have long had lane departure warnings, but if you're unfamiliar with the idea, it's when the car emits a vibration through the steering wheel to let the driver know to straighten out if one of the wheels crosses a lane divider. Speed Assist lets the car use a combination of new camera and GPS system to record a particular road's speed limit. At that point, there are a number of signals, including a gray line on the speedometer or an audible chime, to warn the driver that he or she is running the risk of attracting the attention of a Smokey (for you Burt Reynolds fans) and a possible speeding ticket. Tesla has released an official statement that says: Starting recently, some Model S being delivered in North America come equipped with two new features. The features are lane drift detection, which will deliver a warning via vibration in the steering wheel if the driver starts to drift from the lane without signaling, and speed limit display, which will inform the driver of the speed limit and alert them when it is exceeded. These features are necessary to meet the latest standards in the European market, but we have decided to integrate them into Model S delivered worldwide. Whether these features will be an option or included standard is not yet known, but Tesla has said that it is not possible to retrofit the new tech into existing vehicles. The new technology is also vital to make autonomous driving possible.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Weekly Recap: Tesla loses money, still dominates the news

Some people get an inordinate amount of attention. In politics, it's Donald Trump. In football, it's Jim Harbaugh. And in the auto world, it's Elon Musk and his always-fascinating electric car company, Tesla Motors. General Motors is spending $877 million to upgrade a factory. So what! US auto sales are up. Who cares? Tesla has a metal snake that will recharge your car! So was the week in Tesla – er, the industry. Snarkiness aside, Tesla did dominate the news cycle, led by the announcement the company lost $184 million in the second quarter. Tesla also said it expects to deliver between 50,000 and 55,000 vehicles this year, and is preparing for a full launch of the Model X crossover in September. Musk also made news during the earnings call by simply not answering a question about ride sharing, leading to speculation Tesla could be considering its own operation. While the financials were the arguably the most important company news, reports of a Model S cyber hacking were more compelling fodder for Tesla followers. Researchers were able to attack the sedan and bring it to a stop, though they required access to the car first. Tesla says it already has deployed a remedy for the situation. On a lighter note, Tesla published a video of its metal charger prototype that autonomously uncoils like a snake to power up the company's vehicles, provoking plenty of humorous comments and comparisons. Watch it and decide for yourself. While some of this might seem trivial, much of Tesla's recent attention has been warranted. It's the first startup US automaker in decades to launch from nothing and actually gain traction in the market. Sure, Musk is a lightning rod and Tesla always seems to be in the spotlight. But amid all of the publicity, it easy to lose sight of the new reality: Tesla is a force. OTHER NEWS & NOTES 2016 Chevy Volt lights up 106 MPGe The Chevy Volt's vitals are looking healthier for 2016. The second-generation plug-in hybrid racks up a gaudy 106 miles per gallon equivalent, which is an increase of eight MPGe from the 2015 model. The new Volt can travel 53 miles on electricity, a significant jump from the 2015 Volt's 38-mile range. The new car also has a 420-mile total range when factoring in the capability of the gasoline engine, which is 40 miles greater than the current car offers.
