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 Bladeglider now on the backburner

There have been some big shakeups within Nissan's top executive ranks in the past 12 months, including Johan de Nyscchen leaving Infiniti to run Cadillac and Andy Palmer taking over Aston Martin. With them gone, the automaker's future product portfolio looks to be shifting as well. Among them, the chances are dwindling for the BladeGlider to actually arrive in dealers – already a rumored possibility. New Nissan planning boss Philippe Klein isn't nearly as hot on the idea of the BladeGlider as his predecessors. Where Palmer said last year the vehicle was in the brand's mid-term plan, Klein recently told Autocar that the model was "not among the immediate priorities." He didn't slam the door entirely on potential production, though. "It is still on the table, but at the end of the day it has to make sense to the company." Debuting at the 2013 Tokyo Motor Show, the BladeGlider translated the narrow-front, wide-rear wedge shape of the Deltawing and ZEOD RC racers to the street. In concept form, it used an electric drivetrain with hub-mounted motors, and the driver sat in the center with two passengers flanking them to the rear. According to Autocar, the project to develop a production version got at least as far as creating test cars from Ariel Atoms. The BladeGlider's renegade styling hasn't been the only thing holding it back from seeing the road, though. Panoz has a pending lawsuit against Nissan that claims the styling for the Nissan ZEOD RC and the BladeGlider infringe on the intellectual property for the Deltawing's design.

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
