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 tests fully autonomous ProPilot tech on Tokyo roads

We've been hearing a lot about Nissan's ProPilot technology lately. ProPilot Assist is coming to the U.S. in the Rogue, as well as the Leaf EV. For this generation, the system allows for Level 2 autonomous driving, which is essentially adaptive cruise control paired with a lane-keeping function. Later, Nissan will add ProPilot Park, which allows the car to park itself. The next generation of ProPilot, though, allows for Level 4 fully autonomous driving, even on urban streets, beginning in 2020. Nissan has announced that it has already tested it on public roads during a demonstration in Tokyo. The prototype test vehicle is an Infiniti Q50. It's fitted with 12 cameras, 12 sonar sensors, nine millimeter-wave radar sensors, six laser scanners and high-definition mapping, all run through artificial intelligence. With this combination of hardware and software, the Q50 prototype can navigate across town or on the highway, automating the entire driving duties from the moment the passenger selects a destination until their arrival. It can tackle busy intersections and respond to obstacles in the road, providing what Nissan claims is a "human-like driving feel that gives passengers peace of mind."

"Today's demonstration is another example of our successful work toward creating an autonomous driving future for all." Autoblog has already had the chance to sample the current generation of ProPilot Assist, in both the Leaf and the Rogue. While there has been a little bit of disagreement in our office, most of us have found the technology to work fairly well, and are looking forward to trying the next generation of semi-autonomous and autonomous systems. As the tech advances, it will only get smoother and smarter.

Nissan Leaf sales up again in February, Chevy Volt dips deeper

Nissan managed to buck the industry's overall trend of lower sales in February with double-digit growth throughout its lineup. That includes a 12th month of record sales for the Nissan Leaf electric vehicle, with the year-over-year numbers up more than a skosh. The February ledger for the Chevy Volt looked much worse, falling 25.6 percent from February 2013 down to 1,210 units. With 1,425 Leafs sold, Nissan came away the winner in a head-to-head competition between these the two early plug-in vehicles for the fourth month in a row. Nissan expects the Leaf's sales momentum continue in March. February Leaf sales were up 118.2 percent, making 2014 the car's best February ever. The car was most popular in San Francisco, CA and Atlanta, GA, two places where the the brutal winter cold that struck most of the country had a limited effect. Nissan said that other markets with notable Leaf sales growth were Honolulu, HI, Dallas/Ft. Worth, TX and Denver, CO. Toby Perry, Nissan's director of EV sales and marketing, said in a statement that Nissan, "amped up advertising in the latter half of February, which already has resulted in an uptick in sales and a significant increase in shopping traffic. We expect to see that momentum continue in March." The Volt retains an overall sales lead against the Leaf, but Chevy's calendar year-to-date sales numbers are down 23.1 percent so far in 2014. Overall, Chevy's sales calendar YTD numbers were down just 7.7 percent, so the Volt is performing below average. As always, we will have a more complete report of last month's green car sales up in short order. Green GM Nissan Electric Hybrid PHEV ev sales
