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 recalling 841k vehicles overseas for steering wheel trouble

A possible issue with a steering wheel bolt in the Nissan Micra (shown) and Cube from the 2002 to 2006 model years has Nissan recalling roughly 841,000 units on four continents, as well as Oceania and the Middle East. On the affected cars, the bolt may not have been tightened properly, which could lead to a loss of steering in a worst-case scenario. According to Reuters, there haven't been any reports of accidents or injuries due to the fault, however.
The Micras affected were built in the UK and Japan, the Cubes in Japan. Nissan has yet to say when the recall will begin, but when it does, owners can take their cars to dealers for repairs; the bolt with either be tightened or, if necessary, a new steering wheel installed.

Recharge Wrap-up: drifting Nissan Leaf video, BMW i sponsors Formula E Berlin ePrix

Watch a Nissan Leaf drift. The folks at Autocar got their hands on Nissan's otherwise tame electric vehicle with a set of plastic rear tires, and got it sideways at the British Drift Championship. If that sounds ridiculous, well, it is, but it's also enormously entertaining. If it sounds particularly tricky to pull off in the front-drive EV, yeah, it's that, too. Check it out the drifting Leaf in the video above, and read more commentary at Hybrid Cars. BMW's i division is the title sponsor of the 2016 Formula E Berlin ePrix. The German automaker, which has already put the i8 and i3 to work as safety and medical cars for the electric racing series, is "delighted to be prominently represented with BMW i at the race weekend in the German capital," according to Joerg Reimann, BMW's Vice President of Brand Experience. The 2016 FIA Formula E BMW i Berlin ePrix - as it is now officially titled - takes place on May 21. Read more from Formula E. A Hawaiian biodiesel plant is the first in the US to be certified as sustainable. Pacific Biodiesel's Big Island Biodiesel plant gets its certification from the Sustainable Biodiesel Alliance, covering both the plant's production and distribution of the alternative fuel. The facility uses waste oil, including used cooking oil, to produce its fuel. The certification system is designed to help worthy biofuel producers show that their processes and products are more than just greenwashing. Read more at Utility Dive, or from The New York Times. India's KPIT Technologies has earned the Promising Innovation in Transport Award at the 2016 Summit of the International Transport Forum in Leipzig, Germany. KPIT earned the special recognition for its system to convert diesel buses to all-electric power. The company's retrofits can be applied to a wide variety of bus platforms.
