NHTSA investigating 200,000 Sentra, Versa models over brakes

The National Highway Traffic Safety Administration has opened a second investigation into Nissan in May. The first covered inaccurate fuel gauges in the 2007 Quest minivan. The latest affects the Sentra and Versa from the 2013 and 2014 model years and the 2014 Versa Note, because of complaints of long brake pedal travel. If NHTSA finds a problem, it could affect an estimated 200,000 vehicles.
At the moment, this is still only a preliminary evaluation "to asses the scope, frequency and safety-related consequences of the alleged defect," according to the report, but it could lead to the full recall. NHTSA is still trying to find whether or not there are accidents, injuries or fatalities related to the problem. At this time, much of the data in the document is still marked Confidential or TBD. Nissan told Reuters in a statement that the company is working with the agency on the investigation and supplying the regulator with further information.
According to NHTSA, its Office of Defects Investigation has received eight complaints about long pedal travel in these models. They allege that the brake pedal goes all the way to the floor when pressed in some cases and doesn't sufficiently slow the vehicle. Autoblog has contacted Nissan for its reaction to the investigation. We will update this story when we receive a reply. Until then, scroll down to read the current investigation report.

Nissan does its best Google Glass impression with 3E headgear [w/video]

The jury may still be out on whether it'll be legal to drive with Google Glass on your nose, but that doesn't mean automakers are going to sit around waiting to see which way the wind blows in one jurisdiction or another. Mercedes-Benz, for example, is already working on ways to integrate its infotainment system into Google Glass, but Nissan is taking things a step further by developing its own wearable tech.
The device is called Nissan 3E, and we don't have much information to go on at this point - just a couple of images, a terse press release and the highly stylized (and rather painful-looking) video below. The Japanese automaker lists internet connectivity and communication as the primary features. But we'd have to assume that, if an automaker is developing it, the device would have some relevance to, you know... driving.
The possibilities are endless, extending from turn-by-turn directions and track information to vehicle metrics and intuitive control of the car's auxiliary controls. We'll have to wait until we get to Tokyo to find out more, but between this and the smartwatch concept it revealed in Frankfurt, Nissan seems to be on a bit of a gadget streak lately.

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.
