Watch Tesla unveil Model S D trim, with autopilot and acceleration demonstrations

By now, you surely have heard that Tesla has introduced autopilot functionality to its cars as well as an all-wheel-drive option. After ten days of rampant speculation leading up to the October 9th announcement, and then the dramatic reveal, pretty much everyone with an internet connection is aware that the California automaker's Model S now has a new bag of automated-driving tricks made possible by a fresh suite of sensors and software. Not to mention the ability to do a mind-boggling 3.2-second sprint to 60 miles per hour from a standstill with the P85D configuration. That all sounds pretty cool, but seeing is believing. To that end, guests were given an opportunity for a brief ride after the event to experience the most visceral aspects of the update for themselves. Going by the flurry of footage that's appeared online, they were pretty impressed. Now, Tesla has also released official video of the monster-robot-aided announcement for those who couldn't make it to the event, and we have it and a curated collection of clips from joyrides below, including one with the CEO himself at the wheel, giving an explainer to Bloomberg.

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.

Move over Audi, now Chrysler has a beef with Tesla's claims

In the same week that Audi said "not so fast" to some claims from Tesla, Chrysler has responded to a new press release from the California-based EV-maker by saying "not exactly, Tesla." The statement, released through the company's blog, comes in response to Tesla claiming it was "the only American car company to have fully repaid the government." Chrysler notes that it, too, recently paid back Uncle Sam from its 2008 bailout. Similar to Audi's recent press release, which was eventually and mysteriously deleted from the German automaker's site, Chrysler is both right and wrong in its statement.
Tesla specifically said that it had paid back the Department of Energy loans that many automakers received - including Fisker and VPG Autos - while Chrysler's retort argues Tesla is "unmistakably incorrect" since it repaid the government in 2011 a full six years early. Technically, the statements from both automakers are correct, but Tesla's startup loan originated from the DoE, while Chrysler's loan came in bailout form from the Troubled Asset Relief Program (TARP). Further, as The Detroit News notes, Chrysler's loan still cost taxpayers well over a billion dollars after all was said and done - those negative assets tied to "old Chrysler" in the bankruptcy did not require repayment.
