Nissan tries to Sway us with video teaser

Nissan is about to unveil the Sway concept at the 2015 Geneva Motor Show this week, but before it does, it's released this teaser clip to give us a better idea of what to expect. Previewed in a teaser image released last week, the Sway concept is the Japanese automaker's proposal to replace its Micra/March hatchback with something a bit more dynamic. It's said to borrow from the success of the Juke and Qashqai crossovers to give the new European-market Pulsar hatchback a baby brother. It's still a bit early to draw conclusions on the design and its prospects for production, but from what we can tell from this video clip, it looks promising. Watch this space for more.

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 Leaf all-electric taxis start pilot program in NYC [w/video]

When New York City picked the Nissan NV200 as its Taxi of Tomorrow, many were surprised that the vehicle wasn't electric, or even a hybrid for that matter. With NYC Mayor Michael Bloomberg on hand, Nissan celebrated Earth Day on Monday by unveiling a pilot program of electric taxis for the city consisting of six 2013 Nissan Leaf EVs, which the mayor referred to as the "taxi of the day after tomorrow."
This pilot program is aimed to show how EVs can operate as taxi cabs, and Mayor Bloomberg said that New York City hopes to have a third of its taxi fleet electrified by 2020. In addition to the six cars, Nissan has also provided three quick chargers around Manhattan, allowing the Leafs to get an 80-percent recharge in just 30 minutes.
According to David Yassky, commissioner of the NYC Taxi and Limousine Commission, "What we have to do now is figure out how you integrate the charging of an electric vehicle into the duty of a taxi cab."
