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:

Toyota 86 most likely to get more power through more displacement? [w/poll]

The Sydney Morning Herald has spoken to Tetsuya Tada, chief engineer of the Toyota 86 (our version of it, the Scion FR-S, is pictured above), and they've been promised that more power is on the way. We've heard a lot of speculation about a more powerful Toyobaru since before the standard model was even launched. The only question now is how the power will be delivered, and among the engine concepts we've already heard about - turbo, supercharger, twin-charged, hybrid - is a new one: more displacement.
Tada said that an engine with more displacement than the current coupe's 2.0 liters is being tested alongside a turbocharged and a hybrid-assisted motor. The SMH cites "inside sources" as saying the displacement option is the one likely to get the go-ahead, and suggests increased bore and stroke will see the engine grow to 2.5 liters, horsepower to about 250 - a 50-hp increase over the present car.
While that's apparently the betting man's solution for the long-awaited increase in gumption, what happens with the next generation could be more wide open than we suspected. According to the report, Tada "hinted that [a successor] could be a radically different car, potentially dropping the boxer engine altogether." He said once they've sorted out the concept for the second generation car, then they'll sort out an engine. That's where a turbo option could come to market, perhaps the turbocharged four-cylinder Toyota is developing for the Lexus NX crossover or a hybrid system that uses a capacitor.
