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.

Andy Palmer leaves Renault-Nissan to serve as CEO of Aston Martin

Aston Martin has been without a helmsman since Ulrich Bez stepped down from the chief executive office at the end of last year, stepping back to serve as non-executive chairman in a semi-retired ambassadorial capacity. The British automaker, now on the cusp of a new era, has been running without a CEO since, but has now named Bez's replacement in Andy Palmer.
If you don't recognize the name, you should: Palmer has worked under the Renault-Nissan Alliance for decades now, rising through the ranks to become one of the top executives under Carlos Ghosn. Most recently he was serving as executive vice president of the entire group and chairman of the Infiniti brand, but like Carlos Tavares, who recently left Renault to run Peugeot, Palmer is now embarking on a new mission as CEO of Aston Martin.
Once the transition period is complete at the start of October, Palmer's role as Chief Planning Officer at Renault-Nissan will be assumed by Philippe Klein, who steps up from his current role as executive vice president of product planning for Renault. Read the statements from both companies below.

Nissan releases GT-R Nismo N-Attack Package workout video at Fuji

Nissan grabbed headlines last year when it debuted the GT-R Nismo and did a blistering 7:08.679 lap around the Nürburgring's Nordschleife. As it turns out, the GT-R that did that round made use of parts that lowered its weight and improved handling. Nissan calls the extras the N-Attack Package, which stands for Nürburgring Attack, and here is a video showing what its upcoming model can do.
The pack makes a variety of changes to make the Nismo GT-R a better handling car. The suspension and brakes are overhauled with Öhlins adjustable dampers, new stabilizer bar and new front brake pads. As you can see the outside is quite different with carbon fiber components replacing the front fenders and hood gurney, plus an adjustable carbon fiber rear wing with angle adjustments and two height settings. The interior gets a carbon fiber rear bulkhead to cut weight as well.
The release date or price for the N-Attack pack hasn't been revealed, but chief vehicle engineer Noboru Kaneko says that the test in the video at Fuji Speedway was to complete "final checks." So the package might not lag too far behind the standard GT-R Nismo. Scroll down to see the Nissan's pinnacle performance car testing on a cloudy day in Japan and read a brief press release about it.
