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 The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility.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.

Investigators Find No Defect Trend With Tesla Motors' Model S

Federal safety investigators said Friday they have found no apparent defect trends in the Tesla Model S, an electric luxury car that has its share of fans and critics. The National Highway Traffic Safety Administration closed a four-month investigation into whether the car's batteries were at heightened risk for underbody strikes and subsequent fires. Even though no defect trend was found, Tesla Motors said in a written statement it would further protect the bottom of its cars with a reinforced underbody shield. The California-based automaker started adding the shields on March 6 and will retrofit older models free of charge. It will also increase the ground clearance of new cars. "This fix should eliminate the potential of a battery-pack fire under all but the most extreme circumstances," said Karl Brauer, a senior analyst at Kelley Blue Book. Although there are more than 194,000 car fires in the United States every year, NHTSA investigators began a preliminary investigation into potential trouble on Nov. 15, 2013 following two Model S fires, one in Tennessee and one in Washington. No one was injured or killed in either fire. Roadway debris punctured the battery pack near the front of the compartments in both cases, damaging the batteries' lithium ion cells that then began "thermal runaway" events. The opposite ends of the debris had dug into the pavement and jutted upward. Tesla called this a "piking effect." The company said it has conducted 152 vehicle level tests, and that the new shields prevented any damage or penetration of the new shields. The first is a rounded, hollow aluminum bar that's followed by a titanium plate. The third layer of protection is made of solid aluminum. (There's video of the new plates in action on the Tesla Motors website). "We have tried every worst-case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event," Tesla Motors founder Elon Musk wrote on the company's blog," essentially equivalent to driving a car at highway speed, into a steel spear braced on the tarmac." Approximately 15,805 vehicles are eligible for the upgrades, which NHTSA says should reduce the frequency of underbody strikes and subsequent fire risks. But the agency did note that the closing of the investigation did not necessarily constitute a finding that a defect does not exist. "The agency reserves the right to take further action if warranted by new circumstances," it said.

Virgin Hotels will provide its Chicago guests car services in the Tesla Model S. Guests can get rides to and from the hotel in a red, dual-motor Model S P85D. Virgin Hotels offers the EV services as part of its sustainability program. "Tesla is the hottest electric car on the road right now, and we're elated to provide our hotel guests with this chic house-car service while also helping to reduce our carbon footprint," says Virgin Hotels vice president of sales and marketing Doug Carrillo. "For Virgin Hotels it's important to provide services our guests desire but do so with the environment in mind whenever possible." Hyundai has announced the first lease of its Tucson Fuel Cell in Canada. Hyundai chose the Vancouver couple, Jennifer Ma and Clayton Crawley, as the first buyers in part because they live near both a dealership and a fueling station, the latter of which sources its hydrogen from a chemical company that produces the gas as a byproduct. Crawley, whose children love the beach, says, "Getting there while reducing our environmental impact will be awesome." Read more at Automotive News. The Federal Transit Administration (FTA) is providing $30 million in grant money for Proterra electric buses. Six transit agencies will buy 28 of the EV buses for a variety of projects. Proterra CEO Ryan Popple calls the funding a "tremendous validation for the company." In total, the FTA is handing out $55 million in grant money for the deployment of American-made electric buses. Four other agencies will receive buses from BAE Systems and New Flyer as part of the program. Read more at Charged EVs.
