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.

These EVs are the worst when it comes to depreciation

The Renault Fluence Z.E. tops the list of the worst depreciating cars according to a ranking compiled by Glass' Information Services, holding just 27.21 percent of its value after a year of ownership and 12,000 miles on the clock. Just as well that you can't buy the sedan anymore in either electric or ICE versions, since it was discontinued last year. This car took a particularly rough hit when Better Place declared bankrutpcy, since the electric Fluence was a specific fit for the aspirations of the battery-swapping company. The Citroen C-Zero hits the list at number four, the Nissan Leaf E at number five, both holding onto just a third of their value after a year. The C-Zero is a rebadged Mitsubishi i-MiEV, and if you bought one stock for the full UK on-the-road price of 26,766 pounds, you'd have a car worth 8,583.86 pounds twelve months later, according to Glass. We're not sure about the wording of the press release, though - it states that those three cars "lost more than three-quarters of their value." Yet the Fluence E Z.E. is the worst offender, and it doesn't dip below 25 percent of its original value. As with those electrics, the rest of the list is made up of aged or barebones ICE models, some of them touted elsewhere for their popularity. You can find the full list and the valuations in the press release below. ELECTRIC CARS AMONG WORST FIRST YEAR DEPRECIATORS Fluence, C-Zero and LEAF all lose more than three-quarters of their value 15/07/15 - Three electric cars are among the worst first year depreciators in a "Bottom 10" released by motor trade valuation market leaders Glass's. The Renault Fluence, Citroen C-Zero and Nissan LEAF E have all lost more than three-quarters of their value after covering 12,000 miles during the last 12 months. Rupert Pontin, head of valuations at Glass, said: "The motor trade and the used car buying public remain interested in electric cars but are still reticent to actually buy them in numbers – and these depreciation figures reflect that fact. "To be fair, these three EVs are among some of the least attractive on the market – the Fluence and C-Zero both have a 'last generation' feel while the LEAF E is on the bottom rung of the LEAF range – but their presence does reflect the fact that the EV sector remains sluggish." Other models in the list include the lowest-powered, entry level versions of some generally popular but aging models such as the Vauxhall Insignia and Renault Megane.

Nissan teases crossover concept for Frankfurt

Nissan released a teaser shot on Monday of a crossover concept that will debut at the Frankfurt Motor Show, and it's quite the tease. Nissan literally gave us no further information. Speculation is rampant as to the vehicle's identity. Autocar suggests it could wear the famous Z badge, which would be a stunning departure from the Z's sports-car heritage. Other theories indicate it could be the next-generation Juke. The photo does show off Nissan's latest design language which is used by the Murano and Maxima in production. The only other info we have is a cryptic line from Nissan's press release: "So can Nissan continue to innovate and move the bar higher? What if Nissan created a new way to feel driving excitement? The answer will come at the Frankfurt Motor Show." Expect more information and images to dribble out and or/leak this week in the run-up to the show. Related Video:
