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 First Drive Review | More power is the icing on top

SAN DIEGO — When Mazda announced that the 2019 Mazda MX-5 Miata was getting a serious increase in power, I was both excited and nervous. I was excited because more power is always exciting, and it was no insubstantial increase. At 181 horsepower, it's the most powerful production Miata ever offered, beating out turbocharged Mazdaspeed Miata's 178 horsepower. Plus it has more revs to play with. But what had me worried was whether this power would mess up the friendly, playful character of the Miata. The 155-horsepower 2.0-liter engine is just about perfect, almost universally loved by the Autoblog staff and other reviewers, with good midrange torque and short gearing that always made it feel quick in nearly every rev range. It felt like the right amount of power for the chassis, too. There was just enough to get it loose without working too hard, but it wouldn't spin you around unexpectedly. I could imagine a couple of ways the new engine could affect that sweet balance, too. A bit too much power could risk some of the Miata's accessibility and predictability. It might become more serious and less fun-loving. I also feared that in pursuit of a higher redline and more horsepower, the low-end of the rev range might become painfully slow. Honda owners know this feeling whenever their VTEC-equipped screamers drop out of the aggressive cam profile, and the Toyota 86 and BRZ suffer from an awful lack of torque right in the mid-range that doesn't recover until nearly redline. All of this was on my mind when the assembled reviewers were briefed by Mazda engineers about the car. It started out like most presentations, with a brief rundown of the goals of the car and what Mazda has done with the model so far. Then came a chart showing the power curves of the NC, current ND, and the 2019 model, and my fear of a loss of low-end grunt dissipated. The amount of power and torque over engine speed is nearly identical between the old and new ND Miatas right up to around 4,500 rpm. And then from there, the 2019 continues making more power all the way to its 181-horse peak at 7,000 rpm, 500 rpm higher than the previous model's redline. This was a good sign. Mazda managed to get these gains with no sacrifices through many small upgrades. The throttle body is wider with a slimmer throttle plate, the intake manifold has longer runners and dual paths, and the intake ports are larger.

Mazda Miata 25th anniversary display is roadster heaven on Earth

As part of the celebration of the 25th anniversary of the MX-5 Miata, Mazda has put together a rather large display at its New York Auto Show booth, showing off significant models from the diminutive roadsters history.
The display represents a healthy split of volume models, with cars 14, 15 and 17 sitting alongside cars 500,000 and 700,000. There are also more than a few concept cars in the offering, such as the Super20 Concept we drove a few years back, as well as older offerings, like the Club Racer concept from the 1989 Chicago Auto Show, the M-Speedster from the 1995 Chicago show and the M Coupe from the 1996 New York Auto Show.
We've put together a gallery of images of the historical Miata display, which you can view above. Take a look and then let us know which of Mazda's awesome roadsters is your favorite.
