Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

Nissan promising autonomous car production by 2020

Nissan will bring the autonomous car to consumers by the end of this decade. The announcement was made by CEO Carlos Ghosn at the company's US headquarters in Irvine, CA. Nissan has already begun construction of a dedicated proving ground for the self-driving cars in Japan, with completion targeted for the end of 2014.
Teaming with MIT, Stanford, Oxford and others, Nissan has already outfitted Leaf EVs with the Autonomous Drive (Nissan's brand name for the tech), a suite of new technologies developed from the brand's existing Safety Shield technology. The current iteration of Autonomous Drive uses the Around-View Monitoring system and laser scanners to analyze the environment, while artificial intelligence systems have been installed to help navigate and operate in a changing environment.
While it's easy to say that Nissan will bring the technology to market within the next six or seven years, it's more difficult to say at what price Autonomous Drive will be available. Most remarkable about all of this is Nissan's claim that self-driving cars will be both commercially viable and available at "realistic prices for consumers." It's expecting Autonomous Drive to be available across its range within two vehicle generations.

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.
