Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

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.

Japanese automakers kick in $800k for new charging-station company

Cynics may say that gathering $800,000 (total) from four of Japan's largest automakers is merely a rounding error. Still, Toyota, Nissan, Honda and Mitsubishi, along with the Development Bank of Japan, are putting those funds to good use. So, that's something. Last week, those five entities officially founded Nippon Charge Service LLC. The company was established to promote plug-in vehicle charging installations across Japan and the automakers seeded it with 80 million yen, or about $786,000 US. Those funds will be used to help business owners deploy charging stations at convenience stores, highway-side locales and other locations that will make it easier for plug-in vehicle drivers (of Toyotas, Hondas, Mitsubishis and Nissans, obviously) to get their juice. The automakers first announced they'd collaborate last year, when they said they'd work with the Japanese government to more than triple the country's publicly accessible chargers to about 17,000 units. No targets were disclosed as far as how many charging stations would be deployed this time out, but, in a move similar to the EZ Charge system in the US, Nippon Charge Service will also have universally-accepted charging cards available by the end of the year to drivers all of those brands' plug-in vehicles to make the charging process a little more seamless.

Japan Automakers Advance Electric Charging Infrastructure with New Company, Nippon Charge Service -Established to help build charging infrastructure for electric-powered vehicles (PHVs, PHEVs and EVs)- Toyota Motor Corporation Nissan Motor Co., Ltd. Honda Motor Co., Ltd. Mitsubishi Motors Corporation Development Bank of Japan Inc. TOKYO, Japan, May 30, 2014 - Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation jointly established a new company, Nippon Charge Service, LLC, on May 26 to promote the installation of chargers for electric-powered vehicles (PHVs, PHEVs, EVs). The goal is to help build a charging network that offers more convenience to drivers in Japan. The new company will promote the installation of chargers, for the good of society and to expand the use of electric-powered vehicles. Related industries are also expected to benefit.
