Recharge Wrap-up: Renault-Nissan at COP21, fast charging viability

Nissan and Renault's combined fleet of 200 EVs drove over 175,000 kilometers (about 108,700 miles) during the COP21 environmental summit in Paris. The largest fleet of EVs for any international conference served as shuttles for attendees, saving almost 182 barrels of oil and 18 tons of CO2 emissions. In addition to providing the Nissan Leaf, Nissan e-NV200, and Renault Zoe EV shuttles, the Renault-Nissan Alliance also set up a network of 90 chargers to support the fleet. 13 of the 27 quick and semi-quick chargers will remain in place for public use.

The company will implement new and upgrade existing traffic technologies in the city, including cloud-based traffic management software, local controller software and an adaptive traffic control system designed to improve traffic flow and safety. In a college town with highly varying numbers of students and visitors throughout the year, "the need to move traffic in and out of the city efficiently is crucial not only for economic and environmental impacts, but for quality of life for Ann Arbor residents," says Marcus Welz, president of Siemens Intelligent Traffic Systems. Many Ann Arborites (your author included) would surely agree.

The researchers found parking spots to be the most popular public charging locations, and that fast chargers saw the most frequent use, suggesting commercial viability for the infrastructure in the short- to medium-term. The study also found that most drivers prefer to charge at home, and do so during peak hours. Incentivization could be necessary to break people from this habit. Read more at Green Car Congress.

Carlos Ghosn in Twitter debut vows to 'tell the truth about what's happening'

TOKYO — Ousted Nissan boss Carlos Ghosn's sudden appearance on Twitter on Wednesday was a surprise move by the businessman that perplexed people and sent journalists scrambling, and not for the first time. The first tweet from the @carlosghosn account on the social network read, "I'm getting ready to tell the truth about what's happening. Press conference on Thursday, April 11." It did not specify a time or place. Featuring a photo of a smiling, grey-haired Ghosn standing in front of a tree with seasonal cherry blossoms, the account initially lacked the blue tick mark to show it had been verified by the social network. That left journalists unsure of its authenticity — particularly as the conditions of Ghosn's $9 million bail preclude him from using the internet. This content is hosted by a third party.

Forty minutes later, when the blue tick appeared, the tweet swept across social media and the account's followers swelled to almost 20,000, from just a handful earlier. Some of the replies appeared sympathetic to Ghosn, with others carrying photos of his now-famous exit from a Tokyo detention center last month. "Stood right alongside you with #GiveGhosnBail. Looking forward to hearing your side," wrote one Twitter user with the name @highmileage. Ghosn had also caught media off guard when he disguised himself in a workman's uniform, cap and face mask to try and give waiting reporters the slip on leaving the detention center after his release on bail. The architect of the Nissan and Renault SA global alliance was then pursued by media as he rode away in a small work van, a Suzuki, topped with a ladder. Ghosn's dramatic fall from grace began with his arrest in November after getting off a private plane at Tokyo's Haneda Airport. He has since been charged with financial misconduct and aggravated breach of trust. On Wednesday, the Yomiuri newspaper said Tokyo prosecutors will soon decide whether to prosecute Ghosn on further charges. A further arrest could jeopardize the planned news conference. It remains unclear if Ghosn sent the tweet or it was sent on his behalf. His bail conditions allow him to access a computer at his lawyer's office but forbid him to use the internet.

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.
