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 didn't have much say in merger talks, but it had what FCA wanted

TOKYO — Nissan wasn't consulted on the proposed merger between its alliance partner Renault and Fiat Chrysler, but the Japanese automaker's reluctance to go along may have helped bring about the surprise collapse of the talks. While Nissan Motor Co. had a weaker bargaining position from the start, with its financial performance crumbling after the arrest last year of its star executive Carlos Ghosn, it still had as its crown jewel the technology of electric vehicles and hybrids that Fiat Chrysler wanted. The board of Renault, meeting Thursday, didn't get as far as voting on the proposal, announced last week, which would have created the world's third biggest automaker, trailing only Volkswagen AG of Germany and Japan's Toyota Motor Corp. When the French government, Renault's top shareholder with a 15% stake, asked for more time to convince Nissan, Fiat Chrysler Chairman John Elkann abruptly withdrew the offer. Although analysts say reviving the talks isn't out of the question, they say trust among the players appears to have been broken. "The other companies made the mistake of underestimating Nissan's determination to say, 'No,' " said Katsuya Takeuchi, senior analyst at Mitsubishi UFJ Morgan Stanley Securities in Tokyo. The Note, an electric car with a small gas engine to charge its battery, was Japan's No. 1 selling car, the first time in 50 years that a Nissan beat Toyota and Honda. Renault and Fiat Chrysler highlighted possible synergies that come from sharing parts and research costs as the benefits of the merger. But what Fiat Chrysler lacks and really wanted was what's called in the industry "electrification technology," Takeuchi said. With emissions regulations getting stricter around the world, having such technology is crucial. Yokohama-based Nissan makes the world's best-selling electric car Leaf. Its Note, an electric car equipped with a small gas engine to charge its battery, was Japan's No. 1 selling car for the fiscal year through March, the first time in 50 years that a Nissan model beat Toyota and Honda Motor Co. for that title. Nissan is also a leader in autonomous-driving technology, another area all the automakers are trying to innovate. "Although Nissan had no say, its cautionary stance on the merger ended up being very meaningful," Takeuchi said.

Nissan's Le Mans prototype V6 to power next GT-R

You can debate all you want about whether racing has any relevance to road cars. And while you're doing that, Nissan will be getting the most out of its GT-R LM Nismo. In fact, the latest reports indicate that the Japanese automaker will use the engine (or some version thereof) in the next-generation GT-R. The Nissan GT-R LM Nismo, for those who may have missed it, is the company's radical attempt to take on the Audis, Porsches and Toyotas of the top-tier LMP1 class in the FIA World Endurance Championship. And to do so at its flagship event, the 24 Hours of Le Mans. Only unlike its rivals, it's not a mid-engined, all-wheel-drive design; both the engine and the driven wheels are at the front end. That engine, however, isn't actually all that radical. It's a 3.0-liter twin-turbo V6 producing 550 horsepower. Potent, but nothing earth-shattering. In fact it's not far off from the 545-hp 3.8-liter unit in the current production GT-R. And according to Top Gear, in speaking with the racing program's director Ben Bowlby, it will be essentially the same engine that will power the next road-going GT-R. Now if you're thinking that something's missing here, you're right: the GT-R LM Nismo packs a lot more than 550 horses. It actually has over 1,250 on tap. The remaining 700 hp are kicked in by the electric component of the racing prototype's hybrid powertrain. The next GT-R is widely expected to incorporate hybrid technology as well, but it won't be good for 700 hp all on its own. And it will almost certainly be driving all four wheels like the current version. Related Video:
