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.

2015 Nissan Murano: Introduction [w/video]

Right as winter turned to spring, a 2015 Nissan Murano was added to the Autoblog long-term test fleet. And while we'd like to report that it's been nothing but smooth sailing, the truth is, as we wrote this, the Murano was undergoing its second stint in the service bay at Suburban Nissan in Troy, MI. It only had 2,400 miles on the odometer. In fact, that's part of the reason why it's taken us so long to introduce this new member of the long-term fleet. After driving the new, third-generation Murano late last year, where we learned that Nissan thinks of its stylish crossover as the flagship for the brand, we decided to order one for a full year's worth of testing at Autoblog HQ. Right from the start, our Murano had problems. At 227 miles, the Check Engine Light illuminated. With no warning messages displayed in the car's onboard infotainment system, we took the Murano to the dealer, where a diagnostic check revealed a faulty O2 sensor. A new part was ordered and we were sent on our way. The Murano went back to the dealer, and now, that issue has been resolved. About 100 miles after the O2 sensor failed, the small storage cover on the center console broke. We aren't really sure how, since this small cubby hasn't had a whole lot of use. Rather than explain it in words, see what's going on in the video below. That's not the only issue we've had with the interior, either. We sort of expected the light, almost white leather to show signs of age during the year-long test, but even after just 2,400 miles, the seats are starting to look worn, with obvious discoloration showing on the driver's seat. What's interesting is, we never had this problem with the light-colored leather on our long-term 2013 Pathfinder. Beyond that, parts of the Murano's interior generally feel poorly put together. The door panels pull away upon light tugging (while closing the door, for example), some of the plastics creak, and we've noticed a few small rattles. Some of this is pretty alarming, especially considering the low mileage of our test car. But it stands to reason that these problems could've been baked in from the start. We're told our car had a couple of issues prior to delivery, and we've heard rumblings from other journalists that their test Muranos haven't been up to snuff. Our early impressions of the Murano were generally positive.
