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.

NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.

Alpine unveils N36 LMP2 car that will race in 24 Hours of Le Mans

This is the Alpine LMP2 competitor you'll see contesting European endurance races this year, including The 24 Hours of Le Mans in June. Parent company Renault showed off the N36 racer at its atelier in Paris, the blue and orange a switch from the yellow, black and white livery Alpine wore last time it was seen in Le Mans way back in 1978 when it won the race.
The team will be run by Signatech-Nissan and the chassis will be powered by a Nissan engine. Nelson Panciatici and Pierre Ragues will contest World Endurance Championship rounds throughout the year, they'll be joined by endurance and IndyCar veteran Tristan Gommendy for Le Mans and Paul-Loup Chatin as the team's reserve driver.
The Alpine N36 will get into its first test this week at Paul Ricard, then experience its first racing miles at the European Le Mans Series round at Silverstone on April 13. The press release below has the full scoop, the photos above have the past and present in high-res glory.
