2015 Nissan Leaf gets B mode standard, new MorningSky Blue color

The Nissan Leaf is getting a few updates for the 2015 model year, some functional, some purely aesthetic. The appearance options will be made available later than the rest, and include a new exterior color called MorningSky Blue, as well as standard 17-inch aluminum alloy wheels for the SV trim level. In terms of driving, the 2015 Leaf gets a dedicated B-mode for every trim level, including the base S car (it was formerly only available in the SV and SL levels). This provides more aggressive regenerative braking when the driver is not on the accelerator - perfect for making the most of those downhill grades. Now every Nissan Leaf includes Normal, Eco-Mode and B-Mode, regardless of trim level. SV and SL trim levels also get a couple new convenience features. For those who find it impossible to disconnect while driving, the Hands-Free Text Messaging Assistant allows them to communicate without taking their eyes off the road, taking their hands off the wheel or risking a distracted driving ticket (perhaps you might want to rethink using it, though). Additionally, SV and SL customers will Voice Destination Entry to make spontaneous rerouting to the theme park a little easier. Of course, a lot of other Nissan cars got some cool upgrades this year. The Quest, NV200 Compact Cargo and V6-powered Altima, for instance, eke out another mile per gallon highway and combined. See what's new in the Leaf and the rest of the Nissan lineup in the press release below. The 2015 Nissan Lineup: Charting the Changes Nissan's U.S. sales have significantly outperformed the industry in 2014, up 12.7 percent CYTD through June. Sales have been led by the recently redesigned Altima, Rogue and Sentra – along with other models such as LEAF (+29.4%), JUKE (+44.9%), Frontier (+22.6%) and NV200 (+439.3%), which have shown strong results month after month. This gives the Nissan lineup great momentum heading into the 2015 model year. Headlining the changes for 2015 is the upcoming launch of the all-new Nissan Murano (due in late 2014). As the halo vehicle for Nissan's expanding range of bold crossovers and SUVs, the dramatic 2015 Murano features a new V-motion front end, LED boomerang lights and a unique "floating" roof. Murano's breakthrough exterior design carries into the interior, which offers an engaging social lounge feel through features such as advanced NASA-inspired Zero Gravity front and outboard rear seating and oversized Power Panoramic Moonroof.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

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.
