Nissan's Carlos Ghosn taps the brakes on autonomous car progress

"Self-driving cars remain a long way from commercial reality."
Nissan CEO Carlos Ghosn shocked the automotive industry last year when he announced that his company plans to offer consumers an autonomous car by 2020. The automaker even showed off its self-driving Leaf prototype as proof. He was bolder recently with the pronouncement that select markets could have them in 2018, if laws allowed. The boss' optimism appears to be waning, though, and he's now sounding a lot more conservative about the future. While driverless vehicles are still on the way, Ghosn is hedging his bets with a more gradual implementation of several systems.

Nissan Sentra crash rating improves, now Top Safety Pick [w/video]

After a poor showing in the hands of the Insurance Institute of Highway Safety back in 2013, Nissan is back for another round of crash testing with its 2015 Sentra, and it's walking away with a Top Safety Pick. The compact sedan's small overlap front crash test rating improved from "poor" to "good", owing to internal improvements to the A-pillar, door sill and front structure, IIHS said in a statement. The dummy, in this most recent test, was at a low risk of injuries because of the structural changes. Take a look at video of the Sentra's small overlap crash test, available up top, and the official press release down below. 2015 Nissan Sentra earns TOP SAFETY PICK award ARLINGTON, Va. - The 2015 Nissan Sentra has improved from a poor to good rating in the Insurance Institute for Highway Safety's small overlap front crash test, qualifying for the TOP SAFETY PICK award. The small car's front structure, A-pillar and door sill were modified to reduce intrusion in small overlap crashes. In addition, the side curtain airbag was lengthened to protect the driver's head. In the latest test, the driver space was maintained well, with maximum intrusion of less than 5 inches at the lower door hinge pillar. The dummy's movement was well-controlled. The head hit the front airbag and stayed there until rebound, while the side curtain airbag had enough forward coverage to protect the head from contact with side structure and outside objects. Measures taken from the dummy indicate a low risk of injuries in a crash of this severity. In contrast, the 2013-14 Sentra didn't hold up as well in the test. Intrusion measured as much as 13 inches at the lower hinge pillar. The dummy's head slid off the left side of the frontal airbag, and the side curtain airbag didn't offer adequate coverage. Measures from the dummy indicated that injuries to the left leg would be possible in a crash of this severity. Introduced in 2012, the small overlap test replicates what happens when the front corner of a vehicle collides with another vehicle or an object such as a tree or a utility pole. The Sentra's good ratings in the moderate overlap front, side, roof strength and head restraint tests carry over to the 2015 model year. To qualify for the 2015 TOP SAFETY PICK award, a vehicle must have good ratings in those four tests and a good or acceptable rating in the small overlap test. Related Video:

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.
