Four more carmakers join diesel emissions row - Mercedes, Honda, Mazda and Mitsubishi

"Mercedes-Benz, Honda, Mazda and Mitsubishi have joined the growing list of manufacturers whose diesel cars are known to emit significantly more pollution on the road than in regulatory tests, according to data obtained by the Guardian."

"Mazda’s diesel cars had average NOx emissions of 0.293g/km in the real world, between 1.6 and 3.6 times the NEDC test levels. One Euro 6 model, the Mazda 6 2.2L 5DR, produced three times the official NOx emissions. A spokesman for Mazda said: “In compliance with the law, Mazda works hard to ensure that every petrol and diesel engine it makes fully complies with the regulations.”"

Uh-oh! Kind of glad now that Mazda did not bring the diesel CX-5 to North America - I would have totally bought one.

In this case, it's that the official tests aren't close enough to real world use. Of course, these results are much less off than VW's 40 times when pollution controls were actually deactivated. It's also well known that Mazda didn't bring the diesel to the US because it could not meet the stricter US standards. For most its a regulatory problem, except VW's truly bizarre case.
