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:

2014 Toyota Aygo marks the spot [w/video]

Following the leaked pictures we showed you yesterday, we have the full battery of images and info of the all-new Toyota Aygo, in addition to our gallery of live photos from the floor of the Geneva Motor Show.
Like its cousins from Peugeot and Citroën, the Aygo foregoes a diesel engine in favor of a highly efficient gas powerplant. The 1.0-liter naturally aspirated 4-cylinder turns out 68 horsepower and 70 pound-feet of torque. When it hits the market, it'll be with either a five-speed manual transmission or a five-speed, X-Shift automated manual. The former will help the Aygo return 57.3 miles per gallon and hit 62 miles per hour in 14.2 seconds. Opting for the X-Shift variant will net drivers 56 mpg, with 62 arriving in a leisurely 15.5 seconds.
We'll admit, aside from the fuel efficiency, there's nothing terribly great about those numbers. Still, with its compact dimensions - it's only 136 inches long - and a curb weight of no more than 2,000 pounds, it should prove tossable in the bends.

Consumer Reports says Ram 1500 tops fuel economy fight [w/video]

Consumer Reports takes its independent vehicle testing procedures seriously. In an era when we have to question the EPA's official ratings thanks to recent re-evaluations from Ford and Hyundai, an independent voice is important. So, when CR says something is the best, it's worth paying attention to. The Ram 1500 EcoDiesel has "about the same fuel-economy numbers that we typically see in a midsized SUV." – Jake Fisher In this case, CR took a look at the fuel economy of the 2014 Ram 1500 EcoDiesel and found that it came out on top of the fullsize pickup truck pack. The Ram did so with 20 miles per gallon overall and 27 mpg on the highway. CR gave the truck a total road test score of 82. The EPA says that the EcoDiesel 1500 gets 28 mpg on the highway, 20 mpg city and 23 mpg combined. Comparing official EPA numbers, the Ram is also the best among trucks in its class. It's nice when people agree on something. As we know from first-hand, long-distance experience, you can push the 1500 EcoDiesel to 38 mpg. CR found in its own testing that the truck had, "about the same fuel-economy numbers that we typically see in a midsized SUV," said Jake Fisher, CR's director of automotive testing, in a statement. Speaking of midsized SUVs, CR also announced this week that the new Toyota Highlander Hybrid got the top spot in CR's ratings in that category. CR liked pretty much everything about the SUV, saying that the "transitions between electric power and the gas engine are seamless" and that, "the new Highlander also handles better, with a steadier ride and reduced body lean in corners."

RAM ECODIESEL 1500 TOPS CONSUMER REPORTS FULL-SIZE PICKUP TRUCK RATINGS Redesigned Toyota Highlander Hybrid Climbs to Top of Midsized SUV List Yonkers, N.Y.- The Ram 1500 EcoDiesel climbed to the top of Consumer Reports' full-size pickup truck ratings with an impressive performance in the organization's fuel economy tests. The EcoDiesel (82 point overall road test score) turned in a best-in-class fuel economy of 20 mpg overall and 27 mpg on the highway, to help it score better than the previously tested Ram 1500 V8 (81) regular gas version and Chevrolet Silverado 1500 LT (80).
