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 unveils ZEOD RC at Nismo HQ in Japan [w/videos]

At Le Mans this past summer, Nissan unveiled the first prototype for the ZEOD RC, a new hybrid racecar which it intends to field at the famous French endurance race next year. Four months have passed since then, totaling eight month of development, and now Nissan has revealed the final form at the headquarters of its Nismo racing division.
The updated Nissan ZEOD RC benefits from a more streamlined shape with optimized cooling and improved aerodynamics. Although billed as an electric vehicle and not a hybrid, the ZEOD RC pairs a 1.6-liter turbo four with a pair of electric motors. Its regenerative braking system is derived from the Leaf RC, and after 11 laps, it's said to be capable of taking another around the Circuit de la Sarthe under electric power alone, making it the first racecar capable of doing so. Nissan has further stated that it hopes the lessons it garners from this project will help in its development of a new LMP1 to challenge for overall victory at Le Mans in the near future.
The ZEOD RC will be on display at Fuji Speedway this weekend during the six-hour FIA World Endurance Championship race there, after which it will continue its development at the hands of former GT1 champion Michael Krumm and gamer-turned-racer Lucas Ordonez, who will be getting it ready for (and possibly drive it at) next year's 24 Hours of Le Mans. There it will compete - faster than most GTE sportscars, says Nissan - in the Garage 56 spot that once was awarded to the DeltaWing, which Nissan sponsored and to which the ZEOD RC looks conspicuously similar.

Renault-Nissan zero-emissions car sales whir past 100,000 [w/video]

The electric vehicle has gone gold at Renault-Nissan, clocking 100,000 sales in a three-year period that began with the first Nissan Leaf being sold in Silicon Valley, California in 2010. Since then, the Leaf has become the EV champion of the world, selling more than 71,000 units so far, the majority of those in the US. The 100,000th EV sold by the Alliance was also a Leaf and also sold in the US, but on the other side of the country, in Georgia.
By comparison, Renault has sold 30,000 electric vehicles since late 2011, looking after other segments of the EV market with the Kangoo Z.E., Zoe, Twizy and Fluence Z.E. The alliance estimates that its efforts have been driven 5.2 million ion-powered miles and saved 14 million gallons of oil since they appeared. For a bit of sobering context, the US averaged 18.83 million barrels of oil per day in 2011, which is almost 791 million gallons. Per day.
So we're getting there, albeit slowly. Quietly. There's a press release and a video below with more details on the achievement.
