Roller coaster or racecar, which pulls more Gs?

Looking for a thrill? You're not the only one. You'll find kindred spirits at airfields going up for a skydive, atop bridges and towers with bungees attached to their feet and standing in line for roller coasters at the local amusement park. But you'll also find them in the paddock at the racing circuit.
So what's the commonality? G-force. It's like gravity, only in each of these cases, it's experienced by human invention. But which activity subjects your body to the greatest amount of g-force? That's what Nissan set to find out.
Before putting them back in the cockpit, Nismo sent out two of its young hot-shoes - Jann Mardenborough and Mark Shulzhitskiy - to an amusement park in the UK with a camera and a g-force meter to find out if any of the coasters could produce as much lateral gravitational force as an LMP2 racing car. See what they found in the pair of videos, below.

Spitballs flying between Nissan and Fiat

At the 2012 LA Auto Show, Fiat brand chief and recently crowned marketing genius, Olivier François, attempted to distance the Fiat 500e from other electric vehicles, asking rhetorically, "Isn't ugliness the worst kind of pollution?" Nissan has apparently taken issue with these comments, feeling slighted for what it considers digs at the Leaf's styling. In a recent interview with Automotive News, Nissan's marketing chief Simon Sproule shot back, "Let's face it, Fiat has not shied away from controversial styling themselves," he continued, "many would describe many of their products as visual pollution." Ouch.
Sproule says that while the 500e is a "me-too" product, made only to appease US emissions regulations, the Leaf is a serious effort at producing an EV. The Nissan marketing boss points out that the Japanese automaker has invested billions in EV development and production facilities, while Fiat will lose $10,000 on every 500e sold.
However sales of the Leaf in the US are down five percent. Nissan sold just 8,330 Leaf's so far this year, but Sproule contends that it has less to do with styling, and more with the charging infrastructure. Sproule also thinks that Nissan hit a balance between styling and practicality with the Leaf: "It's still very recognizable as a five-seat hatchback, fully functioning, absolutely competitive with the packaging of the Golf of any other mainstream vehicle." For a segment where efficiency is king, isn't that what matters most?

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.
