Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

Nissan shows self-cleaning car coated in nano paint

Washing the car is an activity like mowing the lawn that some people love and others find to be an absolute chore. For the latter group, Nissan may have an answer. Nissan is testing a nano-paint coating that could make the car wash a very infrequent place to visit.
Shown on a European Note hatchback, the key is a special layer of super-hydrophobic and oleophobic material called Ultra-Ever Dry that is sprayed over the paint. It creates a protective layer between the body and environment, and it means that when dirt or water come into contact with the car, the gunk just sheets away.
Nissan admits that the coating is still early in testing. The key will be if the stuff can actually last for the long term, and the company will be analyzing it over the coming months to see how it will react in different conditions. At the moment, the automaker has no plans to offer Ultra-Ever Dry as a standard feature, but it may make it available as an aftermarket addition in the future. Scroll down to watch the video of Nissan testing the stuff in some very dirty conditions.

2014 Nissan Pathfinder Hybrid arrives with supercharged engine, 26 mpg combined

Nissan just launched the fully redesigned Pathfinder for the 2013 model year, and now, there's a fuel-sipping hybrid version making its debut here at the New York Auto Show. The 2014 Pathfinder Hybrid packs all of the same features found in the standard crossover, but offers slightly better fuel economy and an improved cruising range, to boot.
The new hybrid is powered by a 2.5-liter supercharged engine (we're assuming it's a four-cylinder, though Nissan hasn't specified) coupled with a lithium-ion battery and 15-kilowatt electric motor, capable of producing 250 horsepower and 243 pound-feet of torque - 10 less horsepower but three more pound-feet than the standard V6 Pathfinder. Nissan says the hybrid crossover will be rated at 25/27 miles per gallon (city/highway), with a 26-mpg combined rating. This means that on a full tank, the cruising range of the Pathfinder Hybrid is a cool 526 miles.
What's cool about the hybrid packaging is that Nissan has managed not to have it interfere with any of the interior functionality - the Pathfinder Hybrid still packs just as much cargo and passenger space as its naturally aspirated sibling. Official pricing has not been announced, but Nissan expects the hybrid to command an additional $3,000 over the standard model.
