Honda, Merecedes-Benz, Mitsubishi and Mazda are now also implicated in the rigging of emissions tests, according to new data obtained by the Guardian newspaper.
In on-road testing certain Honda 4 x 4 models emitted as much as twenty times the regulatory limits on NOx emissions. These are all vehicles that have passed official emissions testing, so the suspicion is the carmakers have engaged in similar foul play to VW Group.
This comes on top of similar allegations levelled at Nissan, Renault, Citroen, Hyundai, Fiat, Volvo and Jeep. The sheer scale of the NOx testing abuse is finally becoming clear, and is quite clearly endemic amongst car makers worldwide.
These allegation should not be taken lightly, especially in the UK, in which some areas have illegally high levels of NOx pollution which accounts for thousands of premature deaths.
It’s the EU’s job to regulate Diesel car emissions, and all of the cars from these major car brands that we see on the road have passed the EU’s NEDC testing.
At present there is no official evidence of intentional illegal activity, like the use of cheat devices in VW cars, but it is not a huge leap of the imagination to imagine similar practices being widespread across the car industry.
The on-road emissions statistics have been provided by Emissions Analytics, who carefully re-produce real-world conditions in their test programme.
A few of their key findings are as follows:
- Mercedes-Benz’s diesel vehicles emitted an average of more than 2.2 times the official Euro 5 level, and five times more than the Euro 6 level.
- Mitsubishi diesels produces between 1.5 to 3.4 higher than their NEDC figures indicated.
- Certain unnamed 4 x 4 models emitted over 15 times the official levels.
However, some of the car makers have returned fire, with Mitsubishi claiming:
“[the NEDC] was never intended to represent real-world driving”
In fact, out of a total of 50 Euro 6 diesels and 150 Euro 5 diesels tested, only five cars matched their official NEDC statistics in Emissions Analytic’s testing.
It is claimed that powerful motor-industry lobbying has prevented EU testing being made more accurate as it would negatively affect diesel sales within Europe.
These allegations, and the potential harm they may have caused people worldwide, seem to be growing more unsettling by the day, and the idea that the EU may have taken a soft approach on pollution due to pressure from big-business is perhaps just as shocking as the carmakers behaviour.
