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, Renault reveal how they'll reshape alliance to cut costs, regain profit

TOKYO — The auto alliance of Nissan and Renault said Wednesday it will be sharing more vehicle parts, technology and models to save costs as the industry struggles to survive the coronavirus pandemic. Alliance Operating Board Chairman Jean-Dominique Senard said the group, which also includes smaller Japanese automaker Mitsubishi, will have each company focusing on geographic regions. “There is no plan for a merger of our companies,” the chairman said. “Our model today is a very distinctive model ... we donÂ’t need a merger to be efficient.” He stressed the alliance needs to adjust to the “unprecedented economic crisis,” to pursue efficiency and competitiveness, not sheer sales volumes. “Now is the time to rebuild,” Senard said, making clear he believed the alliance remained strong. All automakers are suffering from the pandemic, and scaling back or suspending production, but Nissan was reeling before the crisis struck from a scandal involving its former chairman, Carlos Ghosn. Yokohama-based Nissan is due to report its annual results on Thursday and has forecast it will slip into its first yearly loss in 11 years. Under the latest so-called leader-follower initiative, Nissan will focus on China, North America and Japan; Renault on Europe, Russia and South America and North Africa, and Mitsubishi on Southeast Asia and Oceania, for the benefit of the entire alliance. Nissan Chief Executive Makoto Uchida said the alliance planned to pursue fiscal strength together. “The synergy is huge,” he said. The number of vehicles sharing the same platform will double by 2024, saving 2 billion euros ($2.2 billion), according to Senard. The shared technology will also include electric cars and autonomous driving, platforms and car bodies, the executives said. Nissan is a leader in electric cars with its Leaf, but such technology will be available to the other alliance members, they said. The companies gave few details of how the revamp would deliver in the short term, as the car industry grapples with the fallout from the coronavirus pandemic and pressure to develop less polluting vehicles. They said in a joint statement that they aimed to produce nearly half of their vehicles under the new leader-follower approach by 2025 and hoped to cut investment per model in the scheme by up to 40%. The range of vehicles they produce is expected to fall by 20% by 2025 though the firms did not say how many jobs would go as they shift production.

The Nissan Patrol may become America's next Armada

Plausible rumors are swirling that the Nissan Patrol, the Land Cruiser rival sold outside of North America, might come to the US as a replacement for the unrelated Nissan Armada. That large SUV's future was left ambiguous after the news of the Xterra's discontinuation, as Nissan's press release ominously promised information on the Armada "at a later date" without further elaboration. That left us scratching our heads and thinking that, perhaps, it would be quietly killed off in the future. If the rumors are true, it will be. And then it will be reborn. It'll join its old platform-mate, the Infiniti QX80, on the Patrol platform. The QX abandoned its Titan-based platform in 2011, becoming the Patrol-based QX80. So you can think of the Armada as catching up, a few years late. The QX80 was refreshed last year, a mainly cosmetic nip-and-tuck. The Infiniti utilizes the 5.6-liter, 400-hp V8 and a 7-speed auto, so it's a safe bet that this powertrain will make it into the Armada version. Less likely, but plausible, would be the availability of the new powertrains intended for the Titan XD and upcoming lower-grade Titans. The massive SUV market tends to be a bit conservative, so the Cummins diesel V8 that's the sole engine in the Titan XD right now seems unlikely. The forums are abuzz with a photo of what's purported to be a leaked marketing image of the new Armada, so head to this TitanXDForum thread if you'd like to see what that's about. (Spoiler: it looks a lot like the Patrol above, minus some of the Nismo flair.) Related Video:
