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.

Uber promises 100% electric cars by 2040, commits $800 million to help drivers switch

Uber Technologies Inc on Tuesday said every vehicle on its global ride-hailing platform will be electric by 2040, and it vowed to contribute $800 million through 2025 to help drivers switch to battery-powered vehicles, including discounts for vehicles bought or leased from partner automakers. Uber said that vehicles on its rides platform in the United States, Canada and Europe will be zero-emission by 2030, taking advantage of the regulatory support and advanced infrastructure in those regions. Uber, which as of early February said it had 5 million drivers worldwide, said it formed partnerships with General Motors and the Renault-Nissan-Mitsubishi alliance. In addition to the vehicle discounts, Uber said the $800 million includes discounts for charging and a fare surcharge for electric and hybrid vehicles, the cost of which would be partially offset by an additional small fee charged to customers who request a "green trip." The deals with GM and the Renault alliance focus on the U.S., Canada and Europe. Uber said it was discussing partnerships with other automakers. Uber's plan follows years of criticism by environmental groups and city officials over the pollution and congestion caused by ride-hail vehicles and calls for fleet electrification. Lyft Inc, Uber's smaller U.S. rival, in June promised to switch to 100% electric vehicles by 2030, but said it would not provide direct financial support to drivers. Uber said its goal is to reduce the overall cost of ownership for electric vehicles, which are currently more expensive than gasoline cars. The company also released data on its emission footprint and said it would publish reports going forward. Before the pandemic, electric cars accounted for only 0.15% of all U.S. and Canadian Uber trip miles — roughly in line with average U.S. electric car ownership. At around 12%, the share of plug-in hybrid and hybrid cars was roughly five times as high as the U.S. average. Ride-hail trips overall account for less than 0.6% of transportation-sector emissions, according to U.S. data, but the total number of on-demand vehicles has significantly increased since Uber's launch nearly a decade ago, with 7 billion trips last year, according to Uber's February investor presentation. Uber said its U.S. and Canadian trips with a passenger produce 41% more carbon dioxide per mile than an average private car once miles spent cruising between passengers are included. Uber's plans could be a boon to the auto industry.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands
