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 could have bought a stake in Aston Martin as early as 2012

Aston Martin has a very interesting future ahead of it. While the British brand appeared to be struggling with aging tech for a while, fresh investment from Daimler may have shown a light toward the future with the brand getting engines and electronics from them. Also, former Renault-Nissan top exec Andy Palmer has jumped ship from the French/Japanese automaker to become CEO of the much smaller sports car company. Interestingly, though, new reports from unnamed Nissan sources have indicated that Palmer has been pushing to work with AM for years.
Three unnamed company insiders told Reuters that Palmer made attempts to convince Renault-Nissan CEO Carlos Ghosn in 2012 and 2013 to invest in Aston Martin, but his proposals were shot down both times for unspecified reasons, according to Automotive News. "We looked carefully at the proposal but we passed on it," said one of the sources.
You can easily see why Palmer was eying Aston Martin even back in 2012. It's no secret that the British sports car mavens were in need of extra funding, well before the Daimler investment. Building vehicles these days is only getting more expensive with stronger safety and emissions requirements. Just look at the brand's desperate hope to get a side-impact crash exemption to keep selling its models in the US as an example.

Nissan IDX production model to get sharper, less retro styling

The Nissan IDx seems like the type of concept that auto enthusiasts wish they could be driving. With a compact size, style inspired by the classic Datsun 510 and a rear-wheel-drive powertrain, it certainly ticks many of the boxes that people want. Unfortunately, the car seems to be miles away from actually getting a green light for production, but rumors about the retro coupe's future keep cropping up.
The last we heard about the IDx, the biggest complication with the coupe was that it was a tough project to make profitable. Nissan didn't have a cheap enough rear-wheel drive platform to make the affordable coupe work. The latest rumors point to a potential solution to this problem. According to Motoring from Australia speaking to an insider close to Nissan, the new plan is to tweak the styling to be less retro and adapt the car to work on the platform for the forthcoming, next-generation Z car.
The new look reportedly cribs from the Nissan Sport Sedan Concept from the 2014 Detroit Motor Show, including its floating roof design and sharper edges around the fenders. In terms of power, the source tells Motoring, the IDx could use a naturally aspirated 2.0-liter four-cylinder engine with around 180 horsepower on tap. That might not sound like too much, but remember the Z car itself is rumored to get smaller and lighter when it's new generation hits the stage. If the weight is low enough, potentially using it for the IDx might just work.
