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:

Who sold the most small/midsize pickups in 2012? PickupTrucks.com investigates that, too

PickupTrucks.com has taken another look at the sales of its favorite vehicle bodystyle as part of an ongoing series. According to registration data from R.L. Polk, the Toyota Tacoma easily took the crown as America's best-selling mid-sized pickup, with 133,477 units rolling into new homes in 2012. For comparison, the second-place Nissan Frontier only saw 50,566 registrations.
We feel compelled to point out that before Ford pulled the plug on its ancient Ranger, the company was moving some 75,000 units per year. That number had shriveled to 15,662 by 2012, which was still enough to surpass the Honda Ridgeline. Interestingly enough, one person brought home a brand-new Hummer H3T as well. But mid-sized trucks represent only a fraction of total pickup sales. Dealers sold a total of 241,471 midsizers last year compared to 988,326 half-tons.
That segment was dominated by General Motors with 533,814 sales followed by Ford at 478,204. Ram Trucks trailed behind in third with 241,204 units with Toyota close behind at 229,769. Nissan, meanwhile, remains a distant fifth. Head over to PickupTrucks.com for a closer look at the breakdown in each segment.
