2019 Mazda3 gets only two engines in U.S.; here are details on suspension, AWD

We learned a lot about the 2019 Mazda3 hatchback and sedan when it made its debut at the L.A. Auto Show. It will still have a manual transmission, it will offer all-wheel drive for the first time, and it's a stunner inside and out. But we still had questions about some of the details, so we spoke with folks from Mazda, including a couple of engineers for details on engines, suspension and drivetrains. First off, of the five engines announced for the Mazda3, just two of them are slated for the United States. At launch, the Mazda3 will be offered only with a naturally aspirated 2.5-liter four-cylinder. It's mechanically pretty much the same as what you'll find in the Mazda CX-5 and Mazda6. It even features cylinder deactivation. The only real difference between this engine, its predecessor, and the one in other Mazdas is some minor engine tuning tweaks. Power is almost the same with 186 horsepower and 186 pound-feet of torque, gains of 2 horsepower and 1 pound-foot. Fuel economy is rated at 27 mpg in the city, 36 on the highway, and 30 overall for front-wheel-drive models. We would expect the all-wheel-drive model to have slightly worse fuel economy simply due to extra weight and having to power two extra wheels. The Skyactiv-X engine will become available later in 2019. It will be rolled out in Europe first, with America coming after. When it does come here, it will be offered in states with stricter emissions regulations before coming to other states. While we're on the topic of engines, we also probed a bit about the possibility of the turbocharged 2.5-liter engine coming to the Mazda3. We did get the typical response of not being able to comment on future product. However, they did confirm that the turbocharged engine does in fact fit in the new Mazda3, since it and the naturally aspirated engine are very similar, and the naturally aspirated engine still uses an enormous header, meaning turbo plumbing wouldn't be an issue. Everyone we spoke with at Mazda did emphasize that they are listening closely to buyers, which is what led to the turbo engine being offered on the Mazda6 and CX-5, as well as the introduction of all-wheel-drive to the Mazda3. So, if you, like us, want to see the turbo engine added to the Mazda3, let the company know. They might just do it. Now as for drivetrains, the company is still deciding which trims and which combinations of engines will be offered.

Mazda CEO says rotary not viable, so don't look for a new one

We have some very sad news to report, rotor-heads fans: Don't expect a new rotary-powered vehicle anytime soon. This comes straight from Masamichi Kogai, the CEO of Mazda, which is the only company to ever market a commercially successful rotary-powered automobile in the world. The issue, as it has pretty much always been, is environmental.
While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of fuel and emitting lots of noxious gases into the atmosphere, at least when running on gasoline. And that means the rotary engine will likely only ever be able to power niche vehicles. And that, in turn, means that it is very difficult to turn a profit on vehicles with rotary engines, particularly for a small automaker like Mazda.
"It has to be a viable commercial proposition. If we are going to adopt it, it has to be a product that can generate at least sales of 100,000 units a year. We have to be able to achieve a profit," said Kogai in an interview with Automotive News. Mazda sold 56,203 RX-7 models in the United States (the automaker's biggest market) in 1986. Sales of the RX-8 peaked in 2004, its first full year on the market, with just 23,690 units.

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:
