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.

Nissan CEO Makoto Uchida rules out closer capital ties with Renault

YOKOHAMA — Nissan is committed to its automaking alliance with Renault but will not look to deepen its capital ties with the French automaker any time soon, its new CEO said on Monday. On his first day in the new position, chief executive Makoto Uchida also pledged to repair profitability at Japan's No. 2 automaker and said setting realistic targets would be key toward that goal, as it tries to make a clean break from the leadership of former chairman Carlos Ghosn. "Closer capital ties with Renault are not a focus in the short term," he told reporters. Uchida became CEO of Nissan on Dec. 1, as the car maker tries to recover from a profit slump and draw a line under a year of turmoil after the Ghosn scandal. The ousted chairman is fighting financial misconduct charges in Japan. One of the new CEO's big tasks is to salvage ties with Renault, which have deteriorated since Ghosn's ouster as chairman of both companies. Renault holds a 43.4% stake in Nissan after it saved the Japanese automaker from financial ruin two decades ago, and has pushed for the two companies to merge. In rejecting a notion of a merger with Renault, Uchida, 53, echoes his predecessor Hiroto Saikawa, who stepped down in September. He added that the alliance must re-think how it can serve all of its three members, which also includes Mitsubishi Motors. "The alliance has to benefit each of its partners in terms of revenue and profit," he said. "We need to re-evaluate what has worked and what hasn't worked in the alliance in the past few years." The CEO called for Nissan to set "challenging but achievable" targets, adding that this and the launch of more new car models and vehicle technologies would be key to its financial recovery. Nissan is bracing for its lowest annual profit in 11 years and has slashed its dividend by 65%. Its struggles come at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. "Somewhere along the way we created a culture of setting targets which could not be achieved," Uchida said, adding that this had resulted in a focus on short-term results. "Years of this had led Nissan to its current "difficult situation," he said, using heavy vehicle discounting in the U.S. market as an example of how aggressive sales targets to grow market share had deteriorated the company's brand.

Nissan and Infiniti to get 6 EVs within 5 years

Nissan will get four new electric-powered vehicles, while its luxury division Infiniti will get two over the next five years, a top executive told Automotive News. The six EVs will make up Nissan and Infiniti's share of the 12 electric vehicles planned for Renault-Nissan-Mitsubishi by 2022, though there's no word on how the numbers break down for those other brands. Infiniti last month announced plans for its first all-electric vehicle in 2021, plus new "e-Power" series hybrids like the ones it has introduced in other markets. But the six vehicles divulged by Toshihiro Hirai, Nissan's corporate vice president for powertrain and EV engineering, reportedly include only full battery-electrics and not hybrids. The only full-electric currently offered by either brand in the U.S. is the Nissan Leaf, which was just updated for 2018. Nissan-Renault CEO Carlos Ghosn has been a consistent supporter of electric vehicles, and he has said EVs need greater government incentives, lower development costs and a greater recognition among the buying public of the risks of climate change in order to gain traction among consumers. Last summer, Nissan-Renault announced plans to build electric vehicles in China in a new venture with Dongfeng Motor to meet EV quotas. They'll use a subcompact crossover platform from its own vehicle family.Related Video:
