Anyhow, VW are being punished way too hard for this. 90% of modern diesel cars sold in EU exceed the Euro 6 limit in real world conditions, even though they pass the lab tests. VW was doing the same as all the other manufacturers, they all cheat on the lab tests by various means. One reason is that it's almost impossible to meet the standards when you're focussed on also reducing consumption and CO2 emissions. It's a balancing act, but the legislators are requiring EVERYTHING to be lower at the same time. This is just not possible with normal engine designs, despite adding turbos, EGR and innovative waste regulation and filtering systems.
I find it odd how BMW has been mentioned in the press, since they're probably the closest of all manufacturers to actually meeting the regulations. Volvo and Renault are much worse offenders, and yes, they're worse than VW...
As I said, I'm with Clarkson on this one: "Put simply, then, Volkswagen looked at a set of arbitrary figures that had been dreamt up by a bunch of ill-informed, woolly-headed government officials and chose to ignore them. We are not talking about thalidomide here. Or Bhopal. It’s just a bit of good-natured rule-bending, and we all do that."
Don't get me wrong, I don't think NOx emissions should be ignored, just that VW is being too aggressively targeted for it and the company will suffer for this far more than they should. I've known diesels are not "cleaner" than petrol engines since... well, always, really. The new turbo diesels may have had less smoke, but they weren't much cleaner. You can't ignore the physics and chemistry of compression ignition engines. The decision to switch to CO2 emissions and lower taxes on diesel was really stupid, IMHO. Hopefully this leads to a reduction in taxes on petrol cars instead eventually. A nice litte TSI is a darn sight better than a TDI both to drive and in terms of cleanliness.
@baldgye, the discussion started over TP's comment that Germany's car "industry can not innovate at the rate of the other two makers USA/ Japan". And your "Ford?" response meant you were saying Ford made good American cars. They don't. The model in the picture is an American model Ford Focus. It's not the same as what you were thinking of because that's the European model. I agree, European Fords are good.
