Nissan Leaf sales get January jump as Chevy Volt trends downward

The cold January sales dip hit both the Nissan Leaf and the Chevy Volt last month, but when compared 2014 to 2013's first-month-of-the-year sales totals, one of the two early plug-in vehicles obviously came out on top. The top Leaf market also shifted away from Atlanta for the first time in months. Last year, the Leaf sold just 650 units in January, but it managed to move 1,252 last month, a 92.6-percent increase over 2013 but a big drop from the 2,529 sold in December 2013. Paige Presley over at Nissan told AutoblogGreen that the Leaf has now broken sales records for 11 months straight and that, "we see unique seasonality with some December pull-ahead demand based on federal and state tax incentives." The number one Leaf market also shifted away from Atlanta for the first time in months, moving back to San Francisco. That change could be short-lived. "We had some inventory constraint issues early in the month in Atlanta with end-of-year demand depleting stock," Presley said. "By the time we resolved that, the weather hampered sales." There was not as much good news on the Chevrolet front. Last month, the Volt sold 918 units, down from 1,140 in January 2013 and 2,392 in December 2013. It also marks the first time the Volt has sold in the three-digit range since January 2012, when it sold 603 copies. That string of solid months means that the plug-in hybrid has a roughly 12,000-unit lead over the EV since the two cars brought plug-in vehicles back to the mass market all the way back in December 2010. We will have our full report of January's green car sales up soon.

Renault, Nissan, Mitsubishi announce 35 new EVs by 2030

Renault, Nissan and Mitsubishi are going all-in on EVs. The trio announced plans to release 35 new electric models globally by 2030, ranging from Japan-only kei cars to commercial vehicles, and they sketched out plans to develop next-generation solid-state batteries. The three carmakers will leverage the benefits of economies of scale to keep development and production costs in check. Many of the Alliance's models already ride on a common platform; the Nissan Sentra shares its bones with the third-generation Renault Scenic. Looking ahead, the plan is to build 80% of the cars in the group's global portfolio on common architectures. Renault, Nissan and Mitsubishi are massive companies with a wide lineup of models, so there is no one-size-fits-all solution. Instead, the strategy focuses on five basic modular platforms. CMF-AEV will be for so-called affordable electric cars. KEI-EV will be primarily for kei cars, LCV will underpin commercial vehicles, and CMF-EV was designed to underpin mainstream models including the Ariya. Finally, the CMF-BEV platform will underpin about 250,000 electric cars annually starting in 2024. These include the production version of the retro-styled 5 Prototype introduced in January 2021, at least one car assigned to the Alpine brand, and a replacement for the Micra (previewed above) that will be engineered and built by Renault. Most of these cars will be equipped with a lithium-ion battery pack; that's likely going to remain the best way to power an electric car in the coming years. However, Nissan has been tasked with developing solid-state battery technology that promises to greatly reduce charging times. A solid state battery is tentatively scheduled to enter production by the middle of 2028, though it's too early to tell which model(s) will inaugurate it. Digital services will play a significant role in the Alliance's future lineup as well. By 2026, Renault, Nissan and Mitsubishi plan to connect 25 million cars to their cloud and over 10 million vehicles fitted with "autonomous driving systems" (a vague term that wasn't defined). All told, these investments will cost the group at least ˆ23 billion (around $26 billion at the current conversion rate) in the next five years. What does this mean for America?

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.
