Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.

Nissan pokes fun at Tesla's New Jersey woes, then deletes Tweet

Ever have one of those moments when you release something out onto Twitter, only to think better of it a little while later and reach for that garbage can icon? If so, you are not alone. In fact, you're in the company of a certain Japanese automaker, who recently joined the ranks of those who've suffered an embarrassing bout of tweetus deletus. The Nissan Leaf social media team apparently thought it would be amusing to take a light poke at Tesla Motors and its New Jersey dealer fight woes on its Twitter feed and put together the cheeky graphic which you see above. It was originally published on the micro-blogging network accompanied by the text, "It's okay #NewJersey, you can still #GoElectric with the #NissanLEAF #EV." Funny, right? Not to everyone. The image attracted a bit of mild criticism which, to their credit, Nissan responded to saying, "It's all in #EV love." Soon, however, the original image disappeared from the @NissanLEAF feed. Luckily, we saved a copy for your edification. Rob Robinson, senior specialist of social communications for Nissan, told AutoblogGreen that the Leaf Twitter account is run by an agency, and that the tweet in question, "Was not a tweet that was reviewed or approved by Nissan. We saw it and asked them to take it down." As for the reasoning, Robinson said that, "We thought it was a discussion we didn't need to be weighing in on." While we can see the Nissan point of view, we also appreciate the attempt at being irreverent. Anything to break up the monotony of the stale toast the account usually offers up – "What would you nickname your Nissan Leaf if it was Ocean Blue?" which is the last undeleted Tweet available on the feed, as of this writing. We actually applaud the intention of the Tesla post. It all makes us wonder, though, if the social media team over there isn't in need of a little input on how they might improve its outreach. Since we know our readers are not shy in offering suggestions, we ask you to leave your thoughts and ideas for them in the Comments.

Tesla open-sources all its patents

When Tesla CEO Elon Musk says that he's thinking about something, you definitely need to pay attention because it's likely something big. In an eloquently worded press release (a very rare thing indeed) Musk explains reason after reason why Tesla is opening up all of its patents, effective immediately.
According to the missive, Tesla initially applied for patents on its technology because it was afraid bigger, more powerful automakers would take its ideas and destroy the tiny automaker. However, that hasn't happened. Musk claims that while the company has grown, "electric car programs (or programs for any vehicle that doesn't burn hydrocarbons) at the major manufacturers are small to non-existent." At the same time, the global auto industry continues to grow, and Tesla's main competitors aren't from other electric carmakers, but the traditional internal combustion engine.
Musk claims that if you walk into the company's lobby right now all of its patent forms are gone from the walls. "We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform," he writes.
