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:

Nissan Leaf Nismo RC Concept [w/video]

Nissan took the wraps off its Leaf Nismo RC Concept at the New York Auto Show more than two years ago. As inferred, the vehicle shares many of its pure-EV components with the production Leaf currently sitting in your dealer's showroom. But don't assume the concept is a placid, family friendly, four-place, front-wheel-drive plug-in for grabbing groceries - the RC (as in "Racing Challenge") is a purpose-built, two-seat, rear-wheel-drive prototype race car tuned for the short track.
The RC Concept is fitted with an 80-kW AC synchronous motor driving the rear wheels and drawing power from a 48-module lithium-ion battery. While the motor and battery are nearly identical to the consumer-friendly Leaf, a sleek full carbon-fiber monocoque body shell and a slew of other enhancements mean the RC is 40-percent lighter, a foot shorter in overall height and nearly seven inches wider than its commuter namesake. Nissan says the RC Concept will hit 62 miles per hour in about 6.8 seconds, top out at 93 mph and run for about 20 minutes under race conditions (it will accept an 80-percent charge in 30 minutes with a quick-charger). Understandably, if a zero-emissions motorsport series comes to fruition, the races would be short and nearly silent.
We caught up with the Leaf Nismo RC concept in Southern California, where we were offered the opportunity to zip it around a tight autocross at the former Marine Corps Air Station, El Toro.

Total auto recalls already on record pace in 2014

If you've noticed that there have been more recalls than usual this year, you may be on to something. According to a report from the National Highway Traffic Safety Administration, the US market is on pace to break a record for recalls. In 2013, 22 million cars were recalled. We're only a third of the way through 2014, though, and we've already halved that figure, with 11 million units recalled. That's wild.
Considering the past few months, it shouldn't be a surprise that General Motors is leading the charge, with six million of the 11 million units recalled coming from one of the General's four brands. Between truck recalls, CUV recalls and the ignition switch recall, 2014 hasn't been a great year for GM.
Other recall leaders include Nissan (one million Sentra and Altima sedans), Honda (900,000 Odyssey minivans), Toyota (over one million units in a few recalls), Volkswagen (150,000 Passat sedans), Chrysler (644,000 Dodge Durango and Jeep Grand Cherokee SUVs) and most recently, Ford (434,000 units, the bulk of which were early Ford Escape CUVs). So while it's been a bad year for GM so far, its competitors aren't doing too well, either.
