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.

Tokyo court rejects Carlos Ghosn's bail request

TOKYO — A Tokyo court rejected former Nissan chairman Carlos Ghosn's latest request for bail on Tuesday, more than two months after his arrest. A statement from the Tokyo District Court announcing its decision gave no explanation for prolonging a detention of the 64-year-old executive, which has drawn international scrutiny of Japan's justice system. Ghosn had promised to wear an electronic monitoring ankle bracelet, give up his passport and pay for security guards approved by prosecutors in his latest attempt to gain release from a Tokyo detention center. His family said they will appeal. Ghosn has been in custody since Nov. 19. He had a bail hearing Monday. A Tokyo court rejected an earlier request for bail last week. Ghosn, who led Nissan Motor Co. for two decades, has been charged with falsifying financial reports in underreporting his compensation from Nissan over eight years, and with breach of trust, centering on allegations Ghosn had Nissan temporarily shoulder his personal investment losses and pay a Saudi businessman. Ghosn has said he is innocent, explaining that the alleged compensation was never decided, Nissan didn't suffer losses and the payment was for legitimate services. His wife, Carole Ghosn, appealed for his release through Human Rights Watch earlier this month, saying Ghosn's treatment has been harsh and unfair. Her views echo widespread criticism of Japan's criminal justice system both inside and outside Japan. Suspects who insist they are innocent get held longer. Suspects are held in a cell and routinely grilled daily by investigators without a lawyer present, although lawyers are allowed to visit. Ghosn's lawyer Motonari Ohtsuru has acknowledged Ghosn's release may not come until the trial, which may be six months away. A date for the trial has not been set. Nissan officials say an internal investigation has found that Ghosn had schemes to hide his income and that he used company money and assets for personal gain. A special committee Nissan set up after Ghosn's arrest to strengthen governance held its first meeting Sunday. Seiichiro Nishioka, a former judge and co-chair, told reporters after the meeting that Ghosn had shown questionable ethics, and too much power within the company had been focused in one person. The committee's findings are due by late March. Ghosn's pay was long a sticking point in Japan, where executives generally get paid far less than their American and other Western counterparts.

Nissan won't downsize the next Armada

The Nissan Armada is aptly named, because in relative automotive terms, it's not just the size of a ship - it's the size of a whole fleet. And that, according to reports, isn't about to change.
While many of the larger SUVs on the market are gradually being phased out or replaced by smaller crossovers, Nissan apparently plans on keeping the Armada right where it is. And that means a large, truck-based, eight-passenger colossus, because there are buyers out there who expect no less and Nissan isn't about to lose them to the likes of the Toyota Sequoia, Ford Expedition and Lincoln Navigator, or a General Motors lineup that includes the Chevy Suburban and Tahoe, GMC Yukon and Cadillac Escalade.
That doesn't mean that the next Armada - which Edmunds expects will arrive in 2015 or 2016 - will be immune to constricting environmental regulations, so Nissan will have to get creative. A vehicle the size of the Armada has all the aerodynamic efficiency of the side of a barn, but Nissan is reportedly aiming to streamline that in order to boost efficiency, for starters.
