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:

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!
