Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

Mitsubishi, Nissan will build mini EV together

That minicar project that erstwhile competitors Nissan and Mitsubishi launched about four years ago is about to go a little more maxi. NMKV Co., the joint venture established in June 2011 by the two Japanese automakers to make minicars, is going to get more resources specifically to ease a move into the electric-vehicle sector. Specifically, Nissan, which makes the all-electric Leaf, is going to have a bigger role in the testing, design, and development of the partnership's mini EVs. A memorandum of understand between Nissan and Mitsubishi, maker of the i-MiEV, is in the works. So far, the joint-venture has sold about 500,000 gas-powered three-cylinder compact vehicles under the two automotive brands, so it must be doing something right. The first Nissan Dayz and the Mitsubishi eK Wagon models started production in 2013. Sales of the Nissan Dayz Roox and Mitsubishi eK Space, which went the higher-roof route, began early last year. Nissan and Mitsubishi started making noise about this last summer, when word came out that the little EV may be priced at less than $15,000 in Japan, quite a bit cheaper than either the Leaf or the i-MiEV over there. As with the current models, the future minicar variants will be produced at Mitsubishi's Mizushima factory in Japan. So far, the partnership would only say that details about NMKV's next-generation mini EV will be released "at a later time," so specifics like range and other performance measures will have to wait. Until then, you can take a look at NMKV's press release below. Nissan, Mitsubishi Motors and NMKV reach agreement on planning and development of next-generation minicars Nissan Motor Co., Ltd., Mitsubishi Motors Corporation, and their joint venture NMKV Co., Ltd. today reached an agreement to continue their joint project regarding development of the next generation of current minicar models. The three companies will soon sign a memorandum of understanding. The companies aim to develop more competitive products by optimizing resource allocation and their respective roles and responsibilities. Nissan will be more deeply involved in development operations, such as design development and testing. In addition to its product planning and project development roles, NMKV will strengthen its management capabilities by adding a new department to enhance collaboration with engineering and manufacturing functions. Vehicle production is planned to continue at Mitsubishi's Mizushima Plant.

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.
