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's Carlos Ghosn taps the brakes on autonomous car progress

"Self-driving cars remain a long way from commercial reality."
Nissan CEO Carlos Ghosn shocked the automotive industry last year when he announced that his company plans to offer consumers an autonomous car by 2020. The automaker even showed off its self-driving Leaf prototype as proof. He was bolder recently with the pronouncement that select markets could have them in 2018, if laws allowed. The boss' optimism appears to be waning, though, and he's now sounding a lot more conservative about the future. While driverless vehicles are still on the way, Ghosn is hedging his bets with a more gradual implementation of several systems.

Least reliable cars and trucks of 2022

Related: Most reliable cars and trucks of 2022   Every year, Consumer Reports ranks new cars based on their predicted reliability. We often see Toyota, Lexus, and a few other automakers near the top. But on the other side of the coin, the list of least reliable vehicles sometimes contains surprises.   The organization surveys its members to determine the vehicles that exhibited the most problems over the prior year. Owners are asked about creaks and rattles, the durability of parts and trim, and mechanical issues. Consumer Reports assigns a weight to each problem and then uses them to create a score, with 100 being the best. Some familiar names appear on the list of least reliable vehicles (in order with the lowest predicted reliability score at the top), but there are a few eyebrow-raising models, followed by CR's score: Ford F-150 Hybrid: 4 Hyundai Kona Electric: 5 Lincoln Aviator: 8 Nissan Sentra: 9 Ford Explorer: 16 Chevrolet Bolt: 17 Chevrolet Silverado 1500/GMC Sierra 1500: 19 Jeep Gladiator: 21 Mercedes-Benz GLE: 23 Jeep Wrangler: 24 Consumer Reports noted that sedans are the most reliable vehicle category and found that trucks are far lower on the list. That said, the survey showed that trucks from American brands tended to have better reliability scores, so it’s surprising to see GMÂ’s big two and the Ford F-150 on the list. Part of their problematic ownership experience could be due to the fact that all three trucks have received recent updates, and the Ford was completely redesigned for 2022. New tech, fresh drivetrain components, and other improvements can upset the balance of reliability and make newer models look less dependable than their older counterparts.
