Mazda3 officially unveiled

Mazda has officially pulled the sheets off of its 2014 Mazda3. The all-new compact boasts a wheelbase that's a full 2.4 inches longer than the outgoing model, yet the hatchback is a nearly two inches shorter from stem to stern. The machine is also lower and wider than before, which should give occupants plenty of space indoors. The driver gets treated to a new human-machine interface that features a new Active Driving Display for information like vehicle speed and navigation instructions conveniently in the line of sight. Likewise, the vehicle's infotainment system has received a complete rebuild.
Outside, the new Mazda3 makes full use of the company's KODO design language, and to our eyes, the result is one of the most attractive entries in the segment. Jump under the hood, and buyers can expect to find a Skyactiv-G 2.0-liter gasoline engine with 155 horsepower and 150 pound-feet of torque, though no fuel economy estimates are available. For those looking for a bit more thrust, Mazda also offers a 2.5-liter Skyactiv-G gasoline mill with 184 hp and 185 lb-ft of torque. So far there's no word on the diesel engine available to our friends in Europe.
Both engines can be mated to either a six-speed manual or a six-speed automatic and feature the automaker's i-ELOOP brake energy regeneration systems. The recaptured energy is stored in a capacitor and used to power the vehicle's various electrical systems.

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:

Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.
