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:

Automakers drop support for Trump effort against California emissions

WASHINGTON — Toyota, Fiat Chrysler (now known as Stellantis following its merger with Peugeot) and other major automakers said on Tuesday they were joining General Motors in abandoning support for former President Donald Trump's effort to bar California from setting its own zero emission vehicle rules. The automakers, which also included Hyundai, Kia, Mitsubishi, Mazda and Subaru, said in a joint statement they were withdrawing from an ongoing legal challenge to California's emission-setting powers, "in a gesture of good faith and to find a constructive path forward" with President Joe Biden. The automakers, along with the National Automobile Dealers Association, said they were aligned "with the Biden administrationÂ’s goals to achieve year-over-year improvements in fuel economy standards." Nissan in December withdrew from the challenge after GM's decision in November shocked the industry and won praise from Biden. On Monday, the Justice Department asked the U.S. Appeals Court for the District of Columbia to put the California emissions litigation on hold to "ensure due respect for the prerogative of the executive branch to reconsider the policy decisions of a prior administration." Biden has directed agencies to quickly reconsider TrumpÂ’s 2019 decision to revoke CaliforniaÂ’s authority to set its own auto tailpipe emissions standards and require rising numbers of zero-emission vehicles, as well as Trump's national fuel economy rollback. Asked to respond to the automakers' action, White House climate adviser Gina McCarthy said in a statement that "after four years of putting us in reverse, it is time to restart and build a sustainable future, grow domestic manufacturing, and deliver clean cars for America." California Governor Gavin Newsom praised the automakers on Twitter for "dropping your climate-denying, air-polluting, Trump-era lawsuit against CA" and urged them to join the voluntary framework. TALKS WITH BIDEN Separately, an industry trade group on Tuesday proposed to start talks with Biden on revised fuel economy standards that would be higher than Trump-era standards but lower than ones set during the prior Democratic administration. The Trump administration in March finalized a rollback of U.S. Corporate Average Fuel Economy standards to require 1.5% annual increases in efficiency through 2026, well below the 5% yearly boosts under the Obama administration rules it discarded.

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.
