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 Patrol modified for backseat drivers

The McLaren F1 is most famous for holding the production-car top-speed record for over a decade, but it also made a name for itself by being one of the only production cars with a central driving position, a feature that's extremely rare. But in the world of custom cars, anything can happen. We're not sure if Dubai-based shop King of Customs was inspired by McLaren or is poking fun at backseat drivers (perhaps the builder or the commissioner just has quite the imagination), but its custom fifth-generation Nissan Patrol (the foundation of the Infiniti QX80 in the US) sports utility vehicle takes the term "central-driving position" to the next level. In the Patrol's case, "central" means that the driver's seat and controls are located in the second-row seating area.
It's a pretty clean conversion - if pointless - and we have to wonder how safe it is to drive such a vehicle. The front seats are now passenger seats, and the front airbags have been taken out and replaced with screens, according to King of Customs' Facebook page. So if the driver's view outside is impaired and the SUV is involved in a crash, you'd better hope nobody is up front. The screens on the backs of the front-seat headrests at least provide views from the side-view mirrors via cameras, the shop claims.
Watch the video below, marvel at the extreme impracticality of it all and see the thing drive.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
