Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

Mitsubishi Mirage fuel economy challenge winner duct tapes his way to 74.1 MPG

There's a lesson to be learned from the Mitsubishi Motors' Extreme MPG Hypermiling Challenge: if you want to get your 2014 Mirage to get over 74 miles per gallon, apply duct tape. During the recent event, which ran from Las Vegas, NV to Cypress, CA (where Mitsubishi has its North American HQ), a number of journalists were "allowed to make very minor modifications to their cars from production form." Their solution was to put some colored duct tape over some of the gaps in the front fascia sheetmetal as a way to try and reduce aerodynamic drag. A combination of expertly applied sky blue tape on a Kiwi Green Mirage and careful driving allowed About.com's Aaron Gold to reach 74.1 mpg in the contest. That beat out Popular Mechanics' Mike Austin (driving a Plasma Purple Mirage) and Autobytel's Joni Gray (Sapphire Blue) who tied for second with an average mpg rating of 68.5. The $12,995 car's official EPA fuel economy ratings are 37 city/44 highway/40 combined (continuously-variable transmission model). You can read the Autoblog review of the '14 Mirage here, check out the press release below and keep an eye out for a 30-minute video version of the event on Cars.TV soon. About.com's Aaron Gold Crowned the Winner in Mitsubishi Motors' Extreme MPG Hypermiling Challenge by Achieving an Amazing 74.1 MPG in his 2014 Mitsubishi Mirage Cypress, California, March 13, 2014 – Aaron Gold of About.com, with an astounding fuel efficiency of 74.1 mpg driving his Kiwi Green 2014 Mitsubishi Mirage, finished today with the highest MPG in the Mitsubishi Motors Extreme MPG Hypermiling Challenge. Following Aaron in the 275-mile trek from Las Vegas, Nevada to the Mitsubishi Motors North America, Inc. (MMNA) headquarters in Cypress, California was Mike Austin from Popular Mechanics in his Plasma Purple Mirage and Joni Gray of Autobytel in her Sapphire Blue Mirage. Amazingly, both Mike and Joni tied with an average fuel economy rating of 68.5 mpg. "This was such an exciting event, to have such knowledgeable colleagues in our industry to push the limit to see how high of an MPG can be achieved in our 2014 Mirage," stated Don Swearingen, Executive Vice President of MMNA. "I never figured I'd come in over 70 MPG!" said winner Aaron Gold of About.com. "All three of us kept our speeds down; I think keeping my eyes way down the road, planning ahead and avoiding sudden changes of speed was what gave me the edge.
