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:

2019 Mazda MX-5 Miata Drivers' Notes Review | A little power goes to our heads

The Mazda MX-5 Miata is nearly 30 years old. The current car — dubbed the ND — is in its fourth iteration and packs a number of updates for 2019, most notably a bump of 26 horsepower and 3 pound-feet over the 2018 model. The car now makes 181 horsepower at 7,000 rpm while redline has been raised to 7,500. That might not sound like a lot, but when you're moving fewer than 2,400 pounds of steel, aluminum and plastic, it feels plenty strong. Our test car was a Soul Red roadster with a brown top, an odd but striking combination. A power-retractable top is available as the Miata RF. This top-tier Grand Touring trim comes with features like automatic climate control, heated seats and leather seats. It might not be the most practical or versatile car on the road, but it might just be the most fun for the money. Senior Editor, Green, John Beltz Snyder: I was excited when I woke up to the Miata covered in snow in my driveway. After all, this tester came equipped with Bridgestone Blizzak winter tires. By the time I could pry myself away from my work and take the car for a spin, though, the snow had mostly melted. I still had fun flinging this around on the cold, wet roads. The first thing I noticed was actually what I didn't notice ... I wasn't wishing for just a little more power, for once. Chalk it up to the conditions, or to the extra 26 horsepower Mazda added for 2019, but this felt appropriately potent. If anything, it's just enough to help get the rear end to wiggle a bit and the tires to more readily chirp in second gear. The Miata, fresh from the factory, has learned to do the cha-cha. Oddly enough, though, my wife, who has been salivating over this generation of MX-5 since the first time I brought one home, has cooled on it a little bit. We went out on a date night, and she was hyper aware of the noise and bumps, and I was, too, frankly. Something about bundling up under an icy soft top can kill the mood of this convertible. In the summer, the sound of the engine and telegraphic feel of the road beneath you blend with the warmth of the sun and the tug of the wind in automotive harmony. It's still fun to drive in the cold, but it doesn't quite turn on the charm like it normally does. Associate Editor Reese Counts: I've spent a lot of time behind the wheel of various NDs over the past few years. The weekend I got married, my wife and I drove a Soul Red roadster from Los Angeles to San Francisco for a brief honeymoon.

2020 Mazda CX-9 gets more torque and second-row captain's chairs

The 2020 Mazda CX-9 is here, and it’s even more enticing than the 2019 model year SUV. ItÂ’s not a full redesign, but Mazda shook up the features list to make it more competitive with other three-row crossovers. Most notable (arguably) of all changes comes from a small increase in torque — the 2.5-liter turbocharged four-cylinder gets bumped from 310 pound-feet of torque to 320 pound-feet. Horsepower remains the same at 250 horses. Those figures are only applicable when using 93 octane fuel. They go down to 227 horsepower and 310 pound-feet of torque when on 87. Another new feature is an off-road traction assist button, replacing the traction control button. This new feature is meant to help when navigating rougher terrain. HereÂ’s how Mazda describes its function: “When the diagonal wheels lose traction, off-road traction assist will stop reducing the engine torque and increases the brake force on the wheels without traction. This transfers power to the wheels still on the ground to help allow the vehicle to regain traction and continue the drive.” WeÂ’ll be interested to see how this helps the CX-9 on a snowy Michigan winter day soon. The number of standard features on the base Sport trim is up, too. Now all CX-9s get heated front seats, a power driverÂ’s seat, rain-sensing windshield wipers, heated outside mirrors and auto high-beams. Additionally, Mazda made its full suite of i-Activsense safety features standard. This includes adaptive cruise control, lane-keep assist and other driver assistance niceties. Mazda is also adopting the new key fob design of the Mazda3 for the CX-9. Optional on the Touring and Grand Touring are second-row captainÂ’s chairs. Previously, Mazda only offered bench style seating for the CX-9, so this addition could be a huge turn-on for some folks in this segment. The chairs have armrests, and the lack of a center pull-down means Mazda had to redesign its cupholder layout in back. In CX-9s equipped with the chairs, the cup holders and USB ports are now integrated into the backside of the front center console. If you opt for the captainÂ’s chairs in the Grand Touring or Signature trims, the seats are heated.  Pricing does increase a fair amount for the 2020 CX-9. A base front-wheel drive Sport is now priced at $34,835 including destination, a $1,510 increase from last yearÂ’s base price. The top of the range only got $750 more expensive, though, as the Signature starts at $47,160.
