Recharge Wrap-up: Audi 'Plugging In' video, Citroen e-Mehari rumors

Audi is sponsoring the Newport Folk Festival with its "Plugging In" campaign. In celebration of the event, a video shows the history of the festival, and how plugging in the electric guitar changed music, similar to the way plugging in an electric vehicle changes the way we think about transportation. The video is focuses entirely on music, but at the end, we get the (ahem) plug from Audi: "Audi A3 Sportback e-tron — Plugging In Across America." Watch it above. The first image from Tesla's Firmware 7.0 update has made its way online. The photo shows what appears to be Tesla's new Autopilot feature. The view of the display also suggests that beta testing is happening on main roads between San Francisco and Tesla's home in the tech hub of Silicon Valley. See the photo and read more at Teslarati. The IRS has published a notice regarding its tax code overseeing the treatment of biodiesel credits. It says that, among other things, claimants must reduce their income tax deduction by the amount of the credits given for alternative fuel used or sold during a given quarter in 2014. Biodiesel producers and blenders were eligible for a tax credit of $1.00 per gallon. Read the notice from the IRS, or learn more from Biofuels Digest. Rumors suggest that Citroen will unveil a concept EV based on the C4 Cactus and classic Mehari at the Frankfurt Motor Show. L'Automobile Magazine is reporting that the French automaker has registered the name "e-Mehari," leading to speculation — and even a goofy rendering — from L'Automobile. There has been no official acknowledgement of the e-Mehari from Citroen, so let's not get too excited yet (especially you, Mr. Ewing).

Tesla to introduce all-wheel-drive Model S in 2014?

The Model X sport utility vehicle may not be the first all-wheel-drive Tesla to hit the market. According to The Verge, Tesla is working on an AWD version of its Model S sedan. Currently, the Model S is only available with rear-wheel drive, but sources in the know at Tesla reportedly have said that an AWD version could be released as early as 2014, which is the same year the SUV is expected to be launch.
There was no hint in yesterday's conference call or shareholder letter that an AWD Model S is in the mix. Furthermore, the company's attention currently is focused in other places, such as Europe, Japan and China. But, as The Verge points out, CEO Elon Musk made comments in the 2013 annual shareholder meeting on June 4 about an AWD chassis that would be released in 2014 or 2015 - without the context of the Model X. We have to wonder: were the SUV's drivetrain and chassis also developed with other vehicles in mind?
Our own Domenick Yoney from AutoblogGreen adds another peculiar twist to the Tesla story: "When I spoke to Dorian West, Director of Powertrain Hardware Engineering, at Refuel, I was given the strong impression that I shouldn't expect anything [on the AWD front from Tesla] until after the Model X comes out."

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.
