The Japanese transport ministry has called for the implementation of real-world diesel emissions tests following findings that real-world data for several models from key manufacturers failed to comply with the nation’s vehicle emissions regulations.
According to The Japan Times, diesel variants of the Nissan X-Trail, Land Cruiser Prado and Toyota Hiace commercial van emitted up to 10 times more nitrogen oxide (NOx) than permitted. It was also noted that unlike the Volkswagen diesel scandal, no “defeat devices” were found in any of the tested vehicles.
The Mazda models that were tested, the CX-5 2.2 diesel SUV and the B-segment Demio (Mazda 2) 1.5 diesel fared well in the tests, showing real-world emissions that closely matched its lab results. The Japanese publication also claims that none of the manufacturers have much to worry about in terms of penalties because current legislation only requires vehicles to pass tests in a lab setting and not in the real world.
The Japanese government’s sentiment echoes that of Matthias Mueller, the new Volkswagen Group CEO, who also called for European authorities to adopt real-world emissions and consumption tests.
“The industry-wide discrepancies between official test results and actual usage is no longer tolerable. We, the industry, need to take a new path,” said Mueller. French car maker, PSA Peugeot Citroen, also announced last October (2015) that it will be publishing fuel economy figures for its “main vehicles” based on actual real-world testing conditions.
One such resolve for the matter has been identified as Emissions Analytics’ on-the-road testing programme, which is said to closely match real-world tests. The planned World Light Test Procedure (WLTP), developed under the workings of the UNECE WP29 forum, targets a more realistic representation of fuel economy and pollutant/CO2 emissions.

Real world test only make sense mah
And imposed car tax based on that result too. Those with global quality highly efficient engine like Proton Campro need not to worry also. Surely can score big points and avoid being taxed heavily.
Good on u japan… U always make sence….
GO MAZDA GO!!
Nothing to see here…
Malaysia has no emission standard.
And the Real world consumption is, well, everyone is different.
Wouldn’t it be more exciting if the Japanese Government starts talking about enforcing alternate energy like Hydrogen Fuel Cell and others?? Speed those technology up to achieve economics of scales sooner so that you don’t have to go measure your milliliter Nox next to an exhaust pipe coming out from that Land Cruiser.
now we know why toyota wants to join venture with mazda…toyota next diesel hybrid will be skyactiv-d
Real world consumption, like in Malaysia going up and down hill with 50 bumps and 20 traffic lights before reaching the main trunk road and lining up in front of toll for 20minutes.
Event that shit Axia lab result of 20km/L will become 12km/L.
Buy Mazda and you may save the world.
only if all drive Mazda la.
but better if all manufacturer follow Mazda step.
