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:

Runway Rumble: Nissan GT-R, Ducati 1098 and Lamborghini Reventon Roadster battle it out

One 2.5-mile runway, three different ways to take off: a Ducati 1098, a tuned Nissan GT-R with 580 horsepower and a launch control upgrade, and a Lamborghini Reventon Roadster. You'd naturally expect the Ducati to assert it's lightweight, high-horsepower authority in these matters, but with more than two miles to run, the ride that gets the jump at the line isn't always the one that gets the win.
That comes in especially handy for the Lamborghini, which suffers from a bad start in the first race and just looks plain ordinary in the second, until it finds redemption. You can see how it all goes down in the video below.

Nissan to expand next-gen Titan with more engines, configurations

Not much has changed with the Nissan Titan in the decade that it's been on the market, but the 2015 model year could move the needle enough to turn the truck from an "also ran" in the fullsize truck market to more of a contender. Edmunds had the chance to sit down with Pierre Loing, vice president of product and advanced planning and strategy for Nissan North America, who indicated that not only will a new truck be coming for 2015, it is also expected to take a bigger chunk of the truck market currently dominated by Ford and General Motors.
For starters, the article quotes Loing saying that the next-gen Titan could sell 100,000 units, which is almost five times the number of Titans and the same number of Toyota Tundra trucks sold last year. To accomplish this, Nissan is planning to offer a wider number of models (including a regular cab version) and more powertrain options; we're sure this means Nissan is considering offering a V6. The addition of a regular-cab, V6 Titan would also allow this truck to be more competitively priced.
Will that be enough to attract buyers away from the Big Three domestic trucks? We'll just have to wait and see...
