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.

Andy Palmer leaves Renault-Nissan to serve as CEO of Aston Martin

Aston Martin has been without a helmsman since Ulrich Bez stepped down from the chief executive office at the end of last year, stepping back to serve as non-executive chairman in a semi-retired ambassadorial capacity. The British automaker, now on the cusp of a new era, has been running without a CEO since, but has now named Bez's replacement in Andy Palmer.
If you don't recognize the name, you should: Palmer has worked under the Renault-Nissan Alliance for decades now, rising through the ranks to become one of the top executives under Carlos Ghosn. Most recently he was serving as executive vice president of the entire group and chairman of the Infiniti brand, but like Carlos Tavares, who recently left Renault to run Peugeot, Palmer is now embarking on a new mission as CEO of Aston Martin.
Once the transition period is complete at the start of October, Palmer's role as Chief Planning Officer at Renault-Nissan will be assumed by Philippe Klein, who steps up from his current role as executive vice president of product planning for Renault. Read the statements from both companies below.

The mood at this year’s Paris Motor Show: Quiet

The Paris Motor Show, held every other year in the early fall, typically kicks off the annual cavalcade of automotive conclaves, one that traverses the globe between autumn and spring, introducing projective, conceptual and production-ready vehicle models to the international automotive press, automotive aficionados and a public hungry for news of our increasingly futuristic mobility enterprise. But this year, at the press preview days for the show, the grounds of the Porte de Versailles convention center felt a bit more sparsely populated than usual. This was not simply a subjective sensation, or one influenced by the center's atypically dispersed assemblage of seven discrete buildings, which tends to spread out the cars and the crowds. There were not only fewer new vehicles being premiered in Paris this year, there were fewer manufacturers there to display them. Major mainstream European OEM stalwarts such as Alfa Romeo, Fiat, Nissan and Volkswagen chose to sit out Paris this year, as did boutique manufacturers like Bentley, Aston Martin and Lamborghini. This is not simply based in some antipathy on the part of the German, British and Italian manufacturers toward the French market — though for a variety of historical and societal reasons that market may be more dominated by vehicles produced domestically than others. Rather, it is part of a larger trend in the industry. Last year, Mercedes-Benz announced that it would not be participating in the flagship North American International Auto Show in 2019 — and that it might not return. Other brands including Jaguar/Land Rover, Audi, Porsche, Mazda and nearly every exotic carmaker have also departed the Detroit show. Some of these brands will still appear in the city in which the show is taking place, and host an event offsite, to capitalize on the presence of a large number of reporters in attendance. And even brands that do have a presence at the show have shifted their vehicle introductions to the days before the official press opening in an attempt to stand out from the crowd. In many ways, this makes sense. With an expanding number of automakers, with diversification and niche-ification of models and with wholesale shifts that necessitate the introduction of EV or autonomous sub-brands, there is a growing sense that, with everyone shouting at the same time, no one can be heard.
