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.

Renault invests in sailing ships to reduce its carbon footprint

Renault is taking a page from the golden age of sailing as the company looks towards reducing its carbon footprint through the use of cargo sailing ships. The French automaker recently announced its partnership with Neoline, a start-up enterprise based in the west of France. The firm specializes in reducing the cost and emissions of typical cargo ships, by reintroducing sailing into the transportation equation. Renault's goal is to reduce its global carbon footprint by 25 percent in 2022, as compared to where they were in 2010. This plan also includes a separate target, to lower supply chain emissions - which includes shipping methods such as trucks, trains, and cargo ships - by 6 percent, compared to levels in 2016. Two prototype cargo vessels, complete with a full set of sails, will be introduced by 2021-22. These two ships will travel between the U.S. eastern seaboard (exact locations are TBD) and the French port cities of Saint-Nazaire and Saint-Pierre & Miquelon. Specifics about what exactly the ships will be carrying has not been released, though Renault is part of an extensive global auto alliance that includes Nissan and Mitsubishi. "For nearly 10 years, we have been working to identify the most environmentally sustainable solutions," said Jean-Francois Salles, Alliance global director, production control. "For example, optimizing the fill rates of the containers and trucks, producing eco-friendly packaging, and implementing a multi-modal system." The current demonstration vessel measures in at 446 feet in total length and has more than 45,000 square-feet of sail. For all you big ship fans out there, the Titanic was about double this size, stretching about 882-feet in length. When powered solely by the wind, Neoline CEO, Jean Zanuttini, says that total emissions drop by as much as 90 percent, versus the carbon footprint of a traditional cargo vessel.

Nissan previews new Sway hatchback concept bound for Geneva

Nissan has announced a new concept it's bringing to the fast-approaching Geneva Motor Show with the release of the teaser image above. Bearing the name Sway, the concept previews the Japanese automaker's vision for a new small hatchback for the European market – ostensibly to replace the current model known as the Micra in Europe and Canada and as the March in other parts of the world. There's little to go on from the teaser, but it will clearly adopt the company's latest grille shape, flanked by angled LED headlights and with the requisite spindly door mirrors (or cameras, as the case may be) and oversized wheels packed into flared arches. Beyond that, Nissan hasn't released much in the way of details, except to say that it would apply the same "innovative design" and "radical thinking" that gave birth to the Qashqai and Juke to the small hatchback segment. THIS SWAY FOR EXCITEMENT - NISSAN AT THE 2015 GENEVA MOTOR SHOW Innovative design and product planning gave birth to Nissan Qashqai and Juke, two of the biggest automotive success stories of recent years. What would happen if the company applied the same radical thinking and quality standards to one of the most important sectors in Europe: the small hatchback? To be unveiled at the 2015 Geneva Motor Show, Sway is a glimpse at how a future generation of small Nissan models could look if the company's striking new design language was applied to a European hatchback. The car will be revealed during Nissan's press conference on March 3rd at 11.30am. About Nissan in Europe Nissan has one of the most comprehensive European presences of any overseas manufacturer, employing more than 17,600 staff across locally-based design, research & development, manufacturing, logistics and sales & marketing operations.

Nissan now offers a strong line-up of 23 diverse and innovative models in Europe under the Nissan and Datsun brands.
