Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

Nissan bringing GT-R LM Nismo to Le Mans in 2015 [w/videos]

The Nissan Zeod RC hybrid racecar is certainly cool with its pointy looks, we're excited to see it run, but it isn't built to win races so much as push boundaries. But we might not have too to wait long for one of the Japanese brand's vehicles to claim an overall victory at the 24 Hours of Le Mans, as well. The company is announcing the GT-R LM Nismo racecar with a two-car, full factory effort in the top LMP1 class of the 2015 FIA World Endurance Championship, including Le Mans.
Details about the new racer are almost nonexistent at the moment. The only glimpses that we have are its silhouette under a sheet (above) and the briefest peek at its quad circular taillights in one of the teaser videos. However, the team is making some big promises about the car. "We want to win in a very different way to that of our rivals. We won't be turning up in a vehicle, which is a basically another hybrid that looks like another Porsche, Audi or Toyota - they all look the same to me," said Nissan's Chief Planning Officer and Executive Vice President Andy Palmer in the official announcement. Mechanically, Nissan is revealing even less about the GT-R LM Nismo for now. We are just going to have to wait and find out.
The brand will be aiming for a win in the 24-hour race, but it won't come easy. Nissan will absolutely face stiff competition from the combined forces of Audi, Porsche and Toyota in the top LMP1 class. Scroll down to watch two teaser videos for the newest member of the GT-R family and read the full announcement.

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.
