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.

This is what happens when you drive your Nissan Leaf beyond empty

If you see an AAA truck bringing someone a can of extra gas, it's rarely a big deal, but when an EV driver runs out of charge, people pay attention. Whether its a writer for The New York Times or hardcore Tesla fans, people are curious about this newfangled technology and the things that could go wrong. "I don't know what the opposite of range anxiety is. Range annoyance?" – Robert Llewellyn Well, few people have more fun with their EV than Robert Llewellyn, the actor (best known for Red Dwarf) and star of his own pro-EV show Fully Charged. And he's good at educating people on the EVs as well. In the latest episode, he tries something in his first-gen Leaf that he's never done before: drive until the battery is completely empty. When the car just keeps on going well beyond the official range estimate, Llewellyn gets frustrated. "I don't know what the opposite of range anxiety is," he says. "Range annoyance?" After 91 miles, he finally comes to a stop. Watch the video below. In the end, all Llewellyn needed to do to get up and running again was to get towed home and plug in. A few hours later, he was ready to go, this time with his range estimate at 93 miles. Compare that with the dangers to your gas engine if you run out of gas and you might wonder why so many people worry about an EVs range. This content is hosted by a third party.

Who knew a 1,200-hp GT-R could be so lovely?

The proliferation of 4K cameras and displays is bringing the world some utterly fantastic automotive videos. If you like seeing Jeff Zwart powering up the Pikes Peak course in high-def glory but wish for some hugely powered Nissan GT-Rs in place of the turbocharged Porsche, then this clip shouldn't be missed. Japanese magazine Motorhead brought together a 1,200-horsepower, HKS-tuned R35 GT1000 and an earlier R32 GT-R Group A racer to send them through a tight, mountain road. The clip uses an augmented reality aesthetic to place little pieces of info about the car, driver, and emotions over the scenes, while the coupes are blasting through the forest. The real highlight here is the cinematography and sound. Turn up your speakers to get an earful of the GT-R's gasoline-fueled heart. The cameras mounted on driver Nobuteru Taniguchi turn the world outside the car into an impressionistic blur of green as the trees smear together at such high speeds. The combination of sight and sound offers a fantastic sense of speed. The only, tiny problem with this clip is that the preamble before the coupes thunder off is just a bit too long. If you need an extra minute in your day, skip straight to 1:15 to get immediately to the action. Although, missing the beginning means not seeing an inky black GT-R driving through the Japanese night. According to Speedhunters, the video is meant to promote the theme for Motorhead's latest issue – Japan Tuned. The magazine apparently comes even more video of the two cars playing on the mountain.
