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 Pikes Peak Hill Climb: Practice Day 3

Greg Tracy's MiEV Evolution III topped the time sheets almost 14 seconds ahead of third-place Monster Tajima.
On Thursday, qualifying times for six categories were set on the bottom-section switchbacks of Pikes Peak: Electric Modified - near-unlimited showcases of electric-vehicle engineering; Electric Production - electric vehicles "readily available to the public;" Open Wheel - single engine, open wheeled, open cockpit, single seat vehicles; Open - based upon a production or approved-aftermarket-replica vehicle; Exhibition - a prototype or pre-production vehicle limited to one year of eligibility in this class; and Vintage - vehicles and drivelines from 1990 or earlier.

Mitsubishi previews diesel hybrid pickup concept, next-gen EV for Geneva

Mitsubishi has a long history of tidy little pickup trucks, and the Japanese automaker is apparently looking to extend that heritage in a bolder, bigger way with the Concept GR-HEV, a "sport utility hybrid truck."
The future-think show star, slated to be unveiled at next month's Geneva Motor Show, is actually tipped to be a much larger effort - Mitsubishi says it's applying its hybrid technology to a one-ton truck for the first time. The GR-HEV is powered by a complex powertrain composed of a diesel engine and electric motors, which the company believes is better suited to the sort of heavy-duty work required in the segment. The concept also employs full-time four-wheel drive and a development of Mitsubishi's Super All-Wheel Control system (which governs things like stability and brake force control along with an active center differential) as seen on the production Lancer Evolution.
In related news, Mitsubishi has also confirmed that it will show a next-generation electric showcar at Geneva dubbed Concept CA-MiEV. With this new concept (inset photo), the company says it is looking to build on the learnings of its i citycar and take EVs out of their limited urban roles. To that end, the CA-MiEV boasts "next generation EV systems and high density batteries" that give it a range of 186 miles.
