Mercedes-Benz, Honda, Mazda and Mitsubishi's cars are shown to emit significantly more NOx pollution on the road than in regulatory tests
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.
In more realistic on-road tests, some Honda models emitted six times the regulatory limit of NOx pollution while some unnamed 4x4 models had 20 times the NOx limit coming out of their exhaust pipes.
