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.

Sporty cars from the '80s get retro reviews from MotorWeek

The more things change, the more they stay the same. That's the feeling we're left with after watching the retro-review video above, in which MotorWeek – television's original automotive magazine, as if you didn't already know – takes a look at the 1984 Honda Prelude. A sporty coupe from Japan that lacks the outright performance and thrust of comparable American and European competitors, but makes any perceived slight up with unarguably supreme driving dynamics? That sounds sort of familiar, doesn't it? As always, we love taking a look back at the early days of MotorWeek (the more things change, they more they stay the same, remember?). And it doesn't end there. Far from it, in fact. Not only did MotorWeek bestow upon us the Prelude, Maryland's favorite public television show also unleashed retro reviews of (deep breath) the '82 Fiat X1/9, '84 Olds Cutlass, '88 Lotus Esprit Turbo, '84 Nissan 200SX Turbo, '88 Subaru XT6, '88 Toyota Celica All Trac, '84 Ford EXP Turbo, '89 Suzuki Swift GTi and '89 Mazda 323 GTX.

Auditor had questioned Nissan on payments in Ghosn scandal, source says

TOKYO — Nissan's auditor had repeatedly questioned transactions at the heart of allegations of financial misconduct by former chief Carlos Ghosn, but Nissan said they were proper, a person with direct knowledge of the matter said on Wednesday. Ernst & Young ShinNihon LLC questioned Nissan's management several times, chiefly around 2013, about purchases of overseas luxury homes for Ghosn's personal use and of stock-appreciation rights that were conferred on him. But the Japanese automaker said the transactions and financial reporting were appropriate, the source told Reuters on condition of anonymity. The revelation shows Nissan and its auditor were discussing the transactions, in apparent contrast with Nissan's contention that the alleged misreporting of benefits for Ghosn was masterminded by Ghosn and a key lieutenant. A spokesman for EY ShinNihon, the Japanese affiliate of global accounting firm Ernst & Young, said he could not comment on specific cases. A Nissan spokesman declined to comment. Ghosn was arrested on Nov. 19 as he arrived in Japan. Prosecutors accuse him of falsifying Nissan's annual reports to understate by about half his total compensation of some 10 billion yen ($90 million) over several years. The high-profile former executive has denied the allegations, according to Japanese media. Ghosn remains in custody and is unable to speak publicly. He is represented by former prosecutor Motonari Otsuru, according to Japanese media. Otsuru's law firm declined to comment on Wednesday, and Otsuru has not responded to requests for comment. Nissan has largely pinned the blame on Ghosn and Greg Kelly, a former representative director who was arrested along with Ghosn on the same allegations. "As a result of the investigation, we are certain these two are the masterminds," CEO Hiroto Saikawa told a news conference on Nov. 19, referring to Ghosn and Kelly. He declined to say whether others at Nissan were involved in the alleged wrongdoing. An internal investigation is ongoing, and Nissan says it is cooperating with prosecutors. Nissan and Mitsubishi Motors have removed Ghosn as chairman in the wake of his arrest. The French member of the three-firm alliance, Renault, retains him as chairman and CEO.
