Time slots Tesla Model S among best inventions of 2012

Time Magazine has released its list of the best inventions of 2012, and while a few automotive products made the cut, the Tesla Model S was the only vehicle to nab the honor this year. The magazine cites the electric sedan's sexy aesthetics, lofty 265-mile range and touch-screen cabin controls as reasons for the laurel, though Tesla's network of supercharger stations certainly factored in as well. This is just the latest in long list of accolades for the Model S. As you may recall, Motor Trend recently called the EV the most important car since the Ford Model T, and Automobile Magazine named the five-door its Automobile of the Year.
A total of 25 inventions made the Time list in all, including the self-inflating tires we saw from Goodyear earlier this year. From whimsical indoor clouds crafted by Dutch artist Berndnaut Smilde to a potentially life-saving in-home HIV test, the selections showcase the diversity of human innovation.

How to get incredibly accurate information on your EV's charging power

One would think that paying about $300 to receive a bit of bad news about electric-vehicle charging would be counterproductive. But the fine folks at Teslarati believe that truth is beauty, and they're willing to pay a little extra for the straight dope. There are always losses when taking power from the grid and shoving it into an EV's battery pack. The question is how big are these losses. Teslarati calculated digital read-outs from the dashboard of their Tesla Model S all-electric sedan and found that Tesla builds in about a nine percent efficiency loss when it comes to recharging the car. But the blog thought the Tesla couldn't know exactly what was transpiring between the wall and the battery, so it footed the bill for about $300 to install a digital submetering unit from EKM Metering. With a little calculation, Teslarati was able to figure out after a couple of recharging rounds that the efficiency loss per recharge was closer to 15 percent than nine percent. That means that, instead of paying about 48 cents on the dollar relative to filling up an economy car (factoring in the AAA average price of $3.66 per gallon), Tesla owners are paying about 52 cents on the dollar. Not much compared to paying upwards towards $100,000 for the vehicle itself, but, hey, every cent counts, right? Get all of the details here.

Tesla tidbits: Roadster getting 'exciting' upgrade in 2014

It's been quite a while since we've had news about the Tesla Roadster. The original Tesla electric vehicle hasn't been sold in the US for years and we're in a quiet period before the next-generation shows its face. We were fine with the status quo – it's not like Tesla Motors isn't keeping busy with other projects in the meantime – but something that CEO Elon Musk said during the annual shareholder meeting caught our eye this week: the Roadster will get some sort of update before the end of the year. Details were obviously not disclosed, but Musk did say that something cool is coming: We are planning on I think a fairly exciting upgrade to the Roadster. I'm hoping we can get it done later this year. I did say it would be this year and ... yes, we will get it done this year. ... So, we're going to do something cool with Roadster before the end of this year. Anyone want to guess what this upgrade might be? We know that Roadster batteries are performing better than expected, so we're going to discount that possibility that these older EVs will be made compatible with Tesla's Supercharger technology. But Musk did say at the meeting that this tech is available to other automakers, if they could somehow make an EV that can handle the Supercharger's 135-kW output (a number that Tesla hopes to increase in the future): There is no other electric car that can accept anything close to 135 kilowatts. We are more than happy to have other manufacturers do this. And I've said this publicly on a few occasions. No one's approached us and said they'd like to use it. We are happy to have them do so. They just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network. So, we're very open to such a thing. Musk also confirmed he is open to remaining at Tesla for another half decade or so, until at least when the company's lower-cost, third-generation car gets to "volume production." He said that's maybe four or five years away and that there is "a lot of time" to figure out who will replace him when he does finally step down. We know the car is not going to be the Model E (thanks to Ford's trademark, Musk said) and that the company's targets are for it to cost around $35,000 before incentives and have a range of more than 200 miles.
