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.

Infiniti moves to trademark Eau Rouge

With Formula One taking to Belgium and the famous Spa-Francorchamps circuit this weekend - boasting a reputation as one of the most beautiful courses on the calendar - all eyes will likely be on the tricky Eau Rouge corner, which challenges drivers' high-speed car control over a rolling, tree-lined hill. Infiniti played on the turn's iconic legacy for its ruby red Q50 Eau Rouge concept, and now the brand hopes to trademark the famous racing name so it can keep using it for a potential production version.
In January, the company filed for a trademark on Eau Rouge for "Automobiles and their structural parts; Fuel cell automobiles and their structural parts; Concept cars" with the US Patent and Trademark Office. According to Bloomberg, the application is still under consideration and not yet a guarantee. It's possible that the track could attempt to block the automaker from earning rights to the name. Alternatively, a trademark lawyer tells Bloomberg that the two of them could also strike a deal where Infiniti would pay a small amount for each car sold bearing the title, which could give Spa a bit of extra money in the bank.
Regardless of the name, a vehicle like the Eau Rouge is something enthusiasts have been wanting for years. It combines a modified, 560-horsepower version of the engine from the Nissan GT-R into a four-door sedan covered in aggressive, carbon fiber aerodynamic parts.

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.
