2014 Nissan Leaf named overall cleanest car in US

A research firm has named the zero-emission 2014 Nissan Leaf the cleanest production vehicle in the US, and that's figuring in the full, wheel-to-well lifetime impact of the car on the environment. The Automotive Science Group (ASG) studied more than 1,300 automobiles with at least four seats across nine categories, measuring everything from the amount of fuel needed to run the car during its lifetime to the extraction of natural resources to build the thing in the first place to end-of-life processing. ASG calls the process "wildly complex." The battery-electric Leaf, with its 84-mile single-charge range, took top honors overall, but there were other highly ranked vehicles in different categories. ASG also said that the Mitsubishi Mirage, with its sub-2,000-pound curb weight and 40 miles per gallon fuel economy, was the cleanest among gas-powered vehicles, while the Chevrolet Spark had the lowest cast of ownership over five years. Last month, the American Council for an Energy-Efficient Economy (ACEEE) put together its annual "Greenest" and "Meanest" (notice: we didn't say "Cleanest") lists and put the Leaf at number three. Topping that list was the Smart ForTwo ED battery-electric, but that was followed up by the Toyota Prius C compact hybrid, so fans of those vehicles can now start a healthy debate. The ACEEE uses data from the Environmental Protection Agency and California Air Resources Board to compile its list. We have ASG's press release below. Life-cycle Assessment of 1,300 Models Reveals Best of 2014 FOR IMMEDIATE RELEASE 4 February 2014 [Santa Rosa, CA] – The Automotive Science Group (ASG) conducted a comprehensive life-cycle assessment of over 1,300 automobiles across nine categories to distinguish the BEST model year 2014 vehicles in environmental, economic, social and "all-around" performance. Auto consumers are now equipped with a car buying guide founded on principled facts, a departure from the notoriously subjective test drive "editor reviews" that have long been the industry norm. Using a unique combination of vehicle data inputs that include conventional specifications as well as ground-breaking social, environmental and economic performance indicators, ASG's back-end algorithms are wildly complex, but the front-end results – meaningful vehicle ratings and distinguished awards – are forthright and consumer-friendly. ASG's Automotive Performance Index is for automotive consumers what Google is for web users.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Recharge Wrap-up: Toyota FCV ready for production, Nissan tests Leaf-to-Home energy management

Toyota will begin selling its hydrogen fuel cell vehicle (FCV) in Japan in December. The US and Europe can expect to see the car become available next summer. The FCV, which will likely be called "Mirai" (meaning "future") in Japan, is ready for production ahead of its initial deadline at the end of the fiscal year in March. Toyota planned for annual production of 700 units, but might increase output to meet higher-than-expected demand, which is currently nearing 1,000 units. The cars will mostly be sold in the four cities where a hydrogen fueling infrastructure is already being put in place: Tokyo, Nagoya, Osaka and Fukuoka. Read more at Nikkei Asian Review. Nissan is testing the Leaf EV as part of an energy management system including "Leaf to Home" technology. The system allows the Leaf to help support the power grid during peak energy usage, or provide backup power to a home or building during outages, particularly in emergencies like natural disasters. Using the Leaf's battery to provide electricity during peak hours would lessen the demand on the grid and make the system work more efficiently. Furthermore, if consumers are compensated for the energy saved by using the Leaf for power during periods of high demand, it could encourage more people to adopt the EV.

CDP keeps track of how much companies are disclosing about their impact on global climate change. "The need for data on corporate climate change impacts and strategies to reduce them has never been greater," says CDP CEO Paul Simpson. "For this reason we congratulate those businesses that have achieved a position on CDP's Climate Disclosure Leadership Index." Other perfect scores were earned by Nissan, BMW, Daimler and General Motors. Read more in the press release from Honda below. Scientists at Stanford University have developed a lithium ion battery that can warn users before it overheats. A thin layer of copper between the anode and the layer separating the anode from the cathode acts as a sensor. When it detects lithium buildups from overcharging are approaching the separator, it sends an early alert long before it gets to a point where it would cause a short (which could lead to a fire). The new safety measure could be used in all sorts of battery applications, and not be limited to EVs. Learn more at Phys.org.
