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:

Renault's new Talisman smacks of Maxima [UPDATE]

UPDATE: Well, despite taking up virtually the same amount of space on the road, Nissan spokesperson Josh Clifton confirmed to Autoblog that there's "no linkage on the two vehicles," and that "they weren't developed in tandem." The story has been edited to reflect this information. While Renault and Nissan maintain a strong alliance, the amount of sharing between the two brands is generally pretty subtle. The two automakers haven't made a habit of rebadging the other's products, although we'd surely support rebadging the Renault Clio or Megane as the new Versa or Sentra, especially if the RenaultSport versions were rebadged as Nismo models. That's not likely to change with the new Renault Talisman The big four-door sedan is the latest vehicle to ride on Renault-Nissan's Common Module Family, which also underpins the current Espace MPV. While it may wear Renault's diamond logo and ride on the Espace's platform, the new Talisman sedan takes up almost exactly the same amount of space on the road as the new Nissan Maxima. There's less than two inches separating the two sedans' overall length and wheelbase, while differences in width and height are negligible. The similarities end with the size, though. While the Maxima is only offered with a 3.5-liter V6 and continuously variable transmission, the Talisman will be available with a range of four-cylinder engines. There will be three diesels, available in 110-horsepower, 130-hp, and 160-hp varieties, along with a pair of gas engines, delivering 150 and 200 hp, respectively. The diesels can only be mated to six-speed transmissions (manuals are available for the 110 and 130-hp models), while the petrol mills are limited to seven-speed dual-clutch units. The Renault will also offer four-wheel steering, in the form of the company's 4Control system, and active dampers. While not pictured here, the Talisman will also be offered as a five-door wagon. You can expect to see both the sedan and long-roof models when Renault shows its newest entries in September, at the 2015 Frankfurt Motor Show.

From Maseratis to rental cars | Autoblog Podcast #511

On this week's podcast, Mike Austin and David Gluckman are in a huddle room (again), because the studio was already taken (again). We talk about the all-wheel-drive Dodge Challenger GT (again), as well as the Jeep Wrangler, Maserati Levante, Miata RF (again), and then David waxes poetic on mediocre rental cars (or similar). The episode wraps up with the traditional doling out of Spend My Money buying advice, with some input from an S2000 owner on advice discussed last time. The rundown is below.
