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.

How and why Nissan nearly killed off Infiniti

Launched in 1990, Infiniti was expected to be Japan's answer to BMW (Lexus would end up chasing Mercedes-Benz). Yet things went awry almost right out of the gate. Overlooking the fledgling automaker's now infamous early marketing campaign, its product line over the past twenty-four years has been a roller coaster ride of strong hits (Q45, FX35 and G35) and frustrating misses (M30, I30 and QX4).
In a recent interview with Ward's Auto at the Detroit Auto Show, Nissan Executive Vice President Andy Palmer revealed that the company's luxury brand was almost cancelled by CEO Carlos Ghosn as unnecessary. Infiniti, like most premium marques owned by a volume manufacturer, had fallen into the trap of losing autonomy and pushing its high-end product just like its mainstream models.
The one obvious exception to this industry blunder, said Palmer, was VW Group's Audi brand. Realizing that Audi's impressive comeback over the past two decades shamed even that of actor Robert Downey Jr., Nissan hired Audi veteran Johan de Nysschen to bring Infiniti to its intended glory - and protect it from extinction.

Nissan teases sedan concept for Beijing [w/video]

Nissan is giving us the first tease of its creatively named New Sedan Concept that is premiering at the Beijing Motor Show on April 20. The single image shows the vehicle wearing a diaphanous robe that is just translucent enough to make out its headlights, V-shaped grille and badge. The rest is still a mystery.
The New Sedan Concept is aimed at young, digitally focused Chinese buyers, according to Nissan. Its look came from a collaboration between the company's design centers in China and Japan and was led by Chief Creative Officer Shiro Nakamura. However, the teaser certainly makes the New Sedan look a lot like the Sport Sedan Concept from the 2014 Detroit Auto Show. Hopefully, this is truly a new model and not just a repaint.
Scroll down for the full press release and a video of executive design director Mamoru Aoki discussing the new concept and previous ones.
