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:

Recharge Wrap-up: 61 miles on Autopilot; Mazda CX-9's 32% mpg improvement

A technology analyst at The Motley Fool used Tesla's Autopilot uninterrupted for 61 miles. In order to see how far the Tesla Model S could drive itself without driver intervention, Daniel Sparks set off on the highway from Monument, Colorado, through Colorado Springs and onward toward Pueblo. Only when a truck encroached on his lane did the driver take command of the wheel, rather than waiting to see what the car would do. "With [the] Model S nearly out of Pueblo and onto a long, boring stretch of highway by the time I had to grab the wheel, chances are I could have made it all the way to Colorado City if it wasn't for this interruption," says Sparks. Read the full account at The Motley Fool. The 2016 Mazda CX-9 offers 32 percent better fuel economy than the outgoing model. The front-wheel-drive CX-9, equipped with Mazda's Skyactiv-G 2.5T engine, gets an EPA-estimated 22 mpg city/28 mpg highway/25 mpg combined. The 2016 CX-9 has shed significant weight compared to its predecessor. Its turbocharged engine uses a Dynamic Pressure Turbo system, which improves performance at lower rpm by controlling the degree of exhaust pulsation according to engine speed. The new CX-9 goes on sale this spring. Read more at Green Car Congress. A group of eight US cities have formed the Energy Secure Cities Coalition (ESCC), pledging to switch their fleets over to alternative fuels. Atlanta, Charlotte, Indianapolis, Orlando, Rochester, Sacramento, San Diego and West Palm Beach will retire their petroleum-powered vehicles in favor of EVs and cars using cleaner fuels like natural gas. The cities expect the change to help improve air quality and save taxpayer money on fuel and maintenance costs. The ESCC hopes to grow to include 25 major cities, removing some 50,000 petroleum-fueled vehicles from service and saving 500,000 barrels of oil per year. Read more in the press release below.

2014 Mazda3

The Cure For The Common Corolla
I hate the Toyota Corolla. I'm not talking about the new 2014 model; I can't yet judge a car I haven't driven. I'm referring to the current, old-as-dirt sedan. As an appliance, I get why people buy it, but it represents everything that I, as a car enthusiast, dislike. I don't like looking at it, I don't like sitting in it, and I really don't like driving it. There is absolutely no amount of emotion dialed into any part of the Corolla experience and every other vehicle in the segment is a far better choice. But still, somehow, Toyota sells 'em like hotcakes.
Thankfully, there are a lot of people who agree with me. And for folks like us, companies like Mazda exist. This small Japanese automaker places emotion and driver involvement as its top priorities when creating new products, and mostly - especially in recent years - the end results have been great. The new CX-5 crossover is a doll, to say nothing of the rakish and lovely new Mazda6 that launched earlier this year. And let's not forget the Miata...
