Recharge Wrap-up: Comparing Nissan Leaf performance by climate, natural gas iffy for trucks

A new Carnegie Mellon University study looks at the effects of regional climate variations on the Nissan Leaf. The study shows (unsurprisingly) that the ambient temperatures of different regions have effects on battery performance and the use of climate control, both of which affect range. Efficiency and grid mix determine regional differences in emissions per mile. CMU enumerated many of the differences in performance across the US. For instance, on the coldest day of the year, maximum range can be 70 miles on the Pacific Coast, while it is less than 45 miles in the Upper Midwest. These differences in efficiency can also affect adoption patterns. Read more at Green Car Congress. Battery charger manufacturer CTEK has licensed WiTricity wireless charging technology. CTEK looks to commercialize the wireless power transfer tech for use with electric vehicle batteries, making the "plug-in" aspect of EV charging unnecessary. WiTricity's charging technology stands out for its ability for distance charging via magnetic near field. "We are excited to be on the forefront of the next generation of battery charging products for consumers and industry, and look forward to leveraging WiTricity's ground-breaking technology to bring a new level of convenience and ease of use to market," says CTEK CEO Jon Lind. Wireless charging is convenient for the public, but also especially useful for emergency vehicles, which need to be ready at a moment's notice but also keep electrical systems online while the car is parked.

Switching heavy trucking fleets from diesel to natural gas could make economic sense, but the environmental benefits aren't as certain, according to a new study from UC Davis and Rice University. Certain regions - particularly California, the Great Lakes and mid-Atlantic regions - could benefit from the switch with minimal investment. "But to have an environmental advantage for reducing greenhouse gas emissions would take significant policy intervention," says Amy Myers Jaffe, executive director for Energy and Sustainability at UC Davis. This would mean stricter efficiency standards for natural gas trucks, as well as stronger regulations for methane leakage. Read more in the press release from UC Davis below.

Nissan ex-chief Carlos Ghosn cancels hastily arranged Tokyo press conference

TOKYO — Former Nissan boss Carlos Ghosn on Friday abruptly canceled plans for what would have been his first press conference since his arrest in November, after journalists had been notified about a briefing just two hours earlier. Ghosn's lawyers called to cancel the event that was to be held at the Foreign Correspondents' Club of Japan (FCCJ), but did not immediately give a reason for the abrupt change, an official at the FCCJ told Reuters.Automotive News cited a source as saying his family and media team staged a "last-minute intervention" to get him to call off plans to make his case at the press conference, fearing he would be faced with questions he couldn't answer without tipping his legal team's strategy, or that Japanese prosecutors would take a dim view of him publicly criticizing their actions and attempt to revoke his bail. A spokesman for the Ghosn family in Tokyo did not answer his mobile phone and did not immediately respond to an emailed request for comment. If the conference had not been canceled, Ghosn would have spoken as Japanese Prime Minister Shinzo Abe hosts national leaders at the G20 leaders gathering in Osaka, including U.S. President Donald Trump and French President Emmanuel Macron, who Ghosn's wife Carole have called on to raise the issue of her husband's treatment by Japan's courts. In May a Japanese court dismissed an appeal by Ghosn to ease a bail restriction that bans him from contacting his wife and rejected a subsequent request to allow him a one-off monitored meeting with Carole. His lawyers have argued that that condition violates Japan's constitution and international law on family separations. Ghosn's movements are also monitored and he is only allowed internet access from a computer at his lawyer's office that records the activity for the court. Once among the world's most feted auto executives, Ghosn is awaiting trial in Japan over charges including enriching himself at a cost of $5 million to Nissan, in a scandal which has rocked the industry and exposed tensions in the automaking partnership between Nissan and Renault SA. Since his initial arrest in November last year, Ghosn has been charged four times for crimes which also include underreporting his Nissan salary and temporarily transferring personal financial losses to his employer's books during his time at the helm of Japan's No. 2 automaker.

Nissan alters all CVTs to act less like a stretched rubberband

Among automotive enthusiasts, no one seems to hold a neutral opinion when it comes to continuously variable transmissions. CVTs are either praised for their ability to boost fuel economy or chided for their occasionally poor driving dynamics. Nissan is among the masters of these un-shifting gearboxes in the US, and it uses them in many vehicles in its lineup. However, for the 2015 model year, several models are getting a software update to make their CVTs a bit more like a conventional automatic.
To give drivers the option of feeling gearshifts while on the road, Nissan is adding its D-Step Shift Logic feature to the CVTs in multiple vehicles. Steve Powers, Nissan's senior manager of powertrain performance, told Autoblog the system forces the transmission to "hold a ratio and then shift" to simulate the way that a traditional automatic would. It's simply a change in software, but the company "can't do it to older CVTs," he said, because it would require changes to transmission logic, as well. According to Automotive News, the upgrade is coming to the 2015 Versa, Versa Note (pictured above), Sentra, V6-equipped Altima, Pathfinder and Quest. "We're rolling it out to all programs," said Powers.
Interestingly, buyer perception appears to be pushing the upgrade. John Curl, a Nissan North America regional product manager, told Automotive News that the decision to add the tech partially comes because some owners are bothered that the CVTs aren't changing gears. According to Powers, D-Step "avoids the rubber band feel," that many drivers didn't like. The different sensation of these transmissions seems like something consumers would notice during the test drive, or that the salesperson would inform them about. The same issue cropped up last year when the company was facing customer satisfaction problems among new buyers customers' unfamiliarity with the gearboxes.
