95 Per Cent Of Diesel Cars Puff Out Too Much NOx
When news of the VW emissions scandal broke, there was always that feeling that it was just the tip of the iceberg. Recently we’ve had the police raids at Renault’s factories, German car regulator Kraftfahrt-Bundesamt (KBA) investigating 23 manufacturers for potential infringements, and this week Vauxhall has been dragged into proceedings amid allegations of emissions rigging during services of certain examples of the Zafira.
The latest development comes from extensive emissions testing from consumer magazine Which?. The publication looked into all its data obtained from cars it has lab tested (using more realistic measures than the EU test) since 2012 and found that a whopping 95 per cent of diesel cars tested breached EU limits for nitrogen oxide (NOx) emissions. It also found that one in 10 petrol cars were guilty of a NOx limit breach, with two thirds breaching carbon monoxide limits.
So why are all these cars so damned dirty? Much of it is down to the EU test. As we explained shortly after the whole VW Dieselgate thing blew up, the test is hilariously unrealistic, so it’s no surprise that out in the real world cars emit far more nasty bits out of their exhaust pipes than they’re supposed to, and it’s also no surprise that it’s usually impossible to hit the claimed economy figures.
The solution? Tougher tests, but these aren’t due to come in until September 2017. By then, who knows how this ongoing scandal might have developed…

And im here just sitting, dreaming of a drift missile w201 with a turbodiesel engine..
No smoke no poke
Diesels were better in the 90’s, no emissions *hit, they would virtually run on anything. And best of all, they didn’t smell like ammonia. I love the smell of a pre 2008 diesel!
At first I thought it says “95 per cent of diesel cars puff out too much NOS”
Booooo! Diesel is awesome!
So does this justify VWs scandal or is everyone involved guilty of doing in the first place?
Why does it never post my comments where I want.
So 95% of diesel vehicles since 2012 failed the NOx test, so instead of helping to improve the emissions; let’s make the tests even harder so the manufacturers can’t improve and will always make them look bad. Makes sense to me
that’s why I drive a prius now
Hahahaha my mate just baught a diesel car to save money
I kinda wanted to have a gasoline car, but life and a great deal made me end um in the seat of a pure 1990 Toyota 1.8 Diesel corolla
I know emissions are bad, it’s a old car, had good emissions, for the time it was launched
One thing I read about was some type of “catalitc converter” thing that envolved in the exaust fumes of the diesel engine pass throug a mix of ureia or something like that to minimize NOx emissions, but was like once, nobody realy seems to develop that
Really small screenshot from my old phone about what I said
