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.

Ghosn's legacy: one of the auto industry's most effective execs

"Bob Lutz ... estimated that carrying out the Nissan operation would be the equivalent, for Renault, of putting $5 billion in a container ship and sinking it in the middle of the ocean." So wrote Carlos Ghosn in "SHIFT: Inside Nissan's Historic Revival," which was published in the U.S. in late 2004. Two points about that observation: It is in keeping with Lutz's "Often wrong but never in doubt." It shows that Ghosn is a remarkable executive, given that he was able to take Nissan from the edge of financial oblivion to one of the foremost automotive companies (although with alliance partners Renault and, more recently, Mitsubishi). In 1999, Ghosn created what was named the "Nissan Revival Plan." It could have just as well been called the "Nissan Resuscitation Plan." Things were that bad. Now Ghosn is in the midst of legal trouble, accused of financial improprieties of some sort. There is no indication that this is at anything near the scale of what happened at Volkswagen Group. There's malfeasance. And then there's malfeasance. It is likely that this is going to be the end of Ghosn's career, but at age 64, and as a man who has spent nearly the past quarter-century essentially on airplanes, it is probably a good time to leave the stage. What his next act will be — to court or even prison — is an open question. But arguably, Ghosn's performance in the transformation of Nissan and Renault, which also needed some strong medicine to keep it from collapse in the early '00s (although one suspects that the French government would have done its damnedest to keep it propped up), makes him one of the all-time most-notable executives in the auto industry. Ghosn closed plants in both France and Japan and he worked to dismantle the Nissan keiretsu network of interlocked companies, things that were absolutely unthinkable. He established plans with stretch goals in their titles, like the "20 Billion Franc Cost-Reduction Plan," and worked with his people to achieve them, despite the pushback that seemed to come along with the announcement of the plan. As in, as he recalled in SHIFT, "Some people said, 'He's off the deep end. He's raving mad. Doesn't he know that at Renault you set the most conservative goals possible so you can be certain to reach them?' My answer to that sort of thinking was 'You're going to get what you ask for. If you set the bar too low, you'll be a low-level performance.

Recharge Wrap-up: Toyota battery breakthrough, PSA's millionth BlueHDi diesel

Scientists at Toyota have developed battery technology that allows for higher energy density. Using material from hydrogen storage, researchers at the Toyota Research Institute of North America (TRINA) in beautiful Ann Arbor, Michigan have created an electrolyte that works well with a magnesium metal anode. Besides improving energy density for smaller, more powerful batteries, magnesium is also more stable than lithium, making it a safer alternative. Rather than guarding their secret, Toyota is sharing details of this breakthrough in order to advance the technology in hopes of an earlier mass deployment of magnesium batteries. See the video above, and read more in the press release below. Farmdrop – a sort of online farmer's market in the UK – is looking for help naming its electric delivery "vanimals." The Nissan e-NV200 vans are painted and decorated to look like cows, pigs, and chickens. While three of the vans have already been named, fans can suggest their own clever ideas for the rest of the fleet on social media. Those whose names are selected will win a month's worth of shopping on Farmdrop. Cary McCarface, anyone? Read more at the company's website. PSA has built its millionth Euro 6 BlueHDi diesel engine. The automaker builds two diesel engines – a 1.6-liter and a 2.0-liter – at its plant in Tremery, France at a rate of 7,000 engines a day. BlueHDi technology uses three different emissions control mechanisms to filter pollutants out of diesel exhaust, including an oxygen catalyst, an additive filter to remove particulate matter, and a Selective Catalytic Reduction system to reduce NOx. BlueHDi is used in all new Peugeot, Citroen, and DS Euro 6 diesel vehicles. Read more at Green Car Congress. Charging Ahead Toyota Scientists Make Breakthrough on Safer, Smarter Batteries May 04, 2016 ANN ARBOR, Mich. (May 4, 2016) -- For anyone (i.e. everyone) who's ever panicked when their mobile device chirped, "low battery," the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A new breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones. What's the Big Deal with Magnesium? Magnesium metal has long been theorized as a much safer and more energy-dense alternative to current lithium battery technology.
