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 reveals radical BladeGlider concept for Tokyo debut

Radical reinvention of the automobile doesn't happen very often. There's a reason they refer to it as "reinventing the wheel", after all. But that's what a team of racecar designers did with the original DeltaWing concept in 2010. Originally proposed as an IndyCar racer, the project was subsequently redesigned for Le Mans. That's when Nissan got on board, supported the project for a few races, then took the design in its own direction with the ZEOD RC. And now it's taking it to the road... via the auto show.
What we have here is the BladeGlider concept, a proposal for a delta-shaped electric sportscar which Nissan will present at the Tokyo Motor Show in a couple of weeks. Designed to focus on driving pleasure, the BladeGlider is about as radical as they come. Like the DeltaWing and ZEOD RC, it's got a narrow front track and wide rear to minimize drag and optimize stability, packing a 1+2 seating arrangement to put the driver front and center like in a McLaren F1, with upward-swinging doors and underbody aerodynamics to keep it glued to the road. In-wheel motors (of unspecified output) provide the power, a lightweight lithium-ion battery (not to mention the carbon-fiber bodywork) keeps it all fearther-like, and weight distribution is heavily biased towards the rear at 30:70.
A radical concept, to be sure, but here's the kicker: Nissan wants to build it. As you can see from the press release below, the BladeGlider "is both a proposal for the future direction of Nissan electric vehicle (EV) development and an exploratory prototype for an upcoming production vehicle". While it would undoubtedly take some time to develop, much less certify for road, seeing one of these - or even better, driving one - on our favorite stretches of tarmac strikes us as a prospect worth waiting for.

2014 Nissan Versa Note pushes the little hatchback forward

Alright, truth time: The Nissan Versa isn't exactly our favorite car in the subcompact class. It's certainly competent, reliable transportation, but it's hardly an emotional purchase choice. Perhaps this new version of the Versa, then, can change our minds a bit. Meet the Versa Note - the cuter, five-door version of the li'l sedan, making its debut here at the 2013 Detroit Auto Show.
Aesthetically, the Versa Note is a pretty pleasant-looking thing; we've seen it before in JDM-spec. It's a decidedly aerodynamic thing, too, with a drag coefficient of just 0.29. And because of that - as well as an efficient little powertrain - the Note will achieve up to 40 miles per gallon on the highway.
Under the hood is Nissan's 1.6-liter inline four-cylinder engine churning out a furious 109 horsepower and 107 pound-feet of torque. Like, well, every other Nissan car, the Versa is equipped with a continuously variable transmission and will drive the front wheels exclusively. Base S models can be had with a five-speed manual transmission, but the moment you step up to a higher trim level, the do-it-yourself shifter goes away.
