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.

Panoz mulls suing Nissan for ZEOD RC's Deltawing likeness

Imitation might be the sincerest form of flattery, but in racing, where something as simple as a car's shape can lead to a competitive advantage, imitation can be a big no-no. That reality is being played out right now, with the DeltaWing prototype and the Nissan ZEOD RC. The two cars, as you can see from the images above, bear a striking resemblance to each other. They're so similar, in fact, that Dr. Don Panoz, one of the big names behind the DeltaWing program, is assigning some legal eagles to investigate any patent infringement.
The similarity shouldn't be a shock, though. Both cars are penned by Ben Bowlby, and the DeltaWing - which will be arriving as a coupe in the very near future - had Nissan branding and power for a not-insignificant amount of time. But for Panoz, the ZEOD RC's resemblance is just a bit too much, as he told Autoweek, "It's been interesting to watch people from Nissan trying to dodge the question, but the fact is that in their own press release they admit that the configuration of the ZEOD is the same as the DeltaWing. And we do have patents, in fact another one was just issued last week. We are in discussions with our legal advisors and we'll see what happens."
Frankly, it's not difficult to see what Panoz means. The general shape of the ZEOD RC, with its wide rear track and narrow front track arrangement - not to mention the headlights mounted over the rear wheel arches and any arrangements not visible under the body - are so reminiscent of the DeltaWing that differences like the shape of its closed cockpit and more upright front end might not prove different enough to avert Panoz's legal action. We'll stay with this one and let you know as more becomes available.

Nissan recalling GT-R, Infiniti crossovers over steering column issue

Nissan has discovered a problem with the steering column on some of its higher-end all-wheel-drive vehicles from a few years back, and has issued a recall in conjunction with the National Highway Traffic Safety Administration to address the issue. The issue revolves around the outer tube on the steering column, which may not be perfectly round. That would put extra stress on the upper steering bearing, which could cause it to fracture, disabling the car's steering ability and potentially leading to a crash. The problem affects Nissan's flagship GT-R supercar – specifically 2009 models manufactured between March 14, 2007, and April 25, 2008) as well as an array of Infiniti crossovers: namely the 2008 EX35 and the 2008-09 FX35 and FX45. In the case of the luxury crossovers, Infiniti dealers are being instructed to replace just the steering shaft, but Nissan dealers will have to replace the entire steering column assembly on the GT-R. All told, the recall is estimated to encompass 16,973 vehicles across the United States. RECALL Subject : Steering Column Tube may be Out of Round Report Receipt Date: FEB 02, 2015 NHTSA Campaign Number: 15V054000 Component(s): STEERING Potential Number of Units Affected: 16,973 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008 Infiniti EX35 vehicles manufactured June 29, 2007, to April 25, 2008, 2009 Infiniti FX35 and FX45 vehicles manufactured October 31, 2007, to April 16, 2008, and 2009 Nissan GT-R vehicles manufactured March 14, 2007, to April 25, 2008. The steering column outer tube may not be round, resulting in extra stress being applied to the upper steering bearing. This stress may cause the bearing retainer to fracture, creating extra play in the steering wheel or a possible loss of steering. CONSEQUENCE: Extra play in the steering wheel or a loss of steering may increase the risk of a crash. REMEDY: Nissan will notify owners, and dealers will replace the steering shaft on the Infiniti EX35, FX35, and FX45 vehicles, and will replace the steering column assembly on the Nissan GT-R vehicles, free of charge. The manufacturer has not yet provided a notification schedule. Infiniti owners may contact customer service at 1-800-662-6200. Nissan owners may contact the GT-R hotline at 1-866-668-1487.
