Half a million VWs recalled, sneaky emissions software.
Discussion
The US Govt has asked VW to recall 500000 Diesel engined vehicles after it was found the engine management knew when the engine was under test and the software reduced the emissions to pass the strict anti pollution regs they have in the States.
Unable to post a link, but this could be interesting.

Interesting, but will this not be similar to what motorcycle manufacturers used to do to pass noise tests?
I don't know if the same test still applies but they used to have to accelerate bikes flat out in 2nd from 30mph over a set distance of 100ft and the max noise level was measured over the run.
As a result, 90s 'superbike' class bikes used to be factory fitted with a huge flat-spot in the mapping to cover this off so that they didn't hit peak torque, and hence peak noise, during the run.
It's nothing new to find automotive companies working around test parameters.

The thing about the USA they have the balls to stand up to companies. i dirve a diesel but they are not good cars for the health of others. The right thing is to tax deisel more and bring petrol prices down, to ensure better emissions. Labour where the ones who gave diesel a tax break and ended up how we are now in the uk.
The USA rightly are not a fan of diesel.

Yes, I was amazed there's half a million diesels in the US.
They quite like their diesels in their bro dozers.I think the U.S. Will look very hard into rogering vw if there is one thing they don't like its domestic manufacturers losing out to 'corruption' that's how they will spin it

I've heard of very similar techniques being used recently in the car industry too.I don't know if the same test still applies but they used to have to accelerate bikes flat out in 2nd from 30mph over a set distance of 100ft and the max noise level was measured over the run.

The "Big 3" have had a bit of a downer on imported diesels for a few years already. The emissions regulations were effectively written by Detroit tomake it very hard for a diesel to pass any of the tests. Net results was that a VAG 4 pot TDI doing 50mpg was branded a dirty yet a big V8 petrol doing 10mpg (on a good day) was classed as clean.

You say that like its a bad thing.Plus you do know diesel emissions are dangerous yes?

All governments EVER do to stop pollution/global warming/climate change etc is add tax to everything........The USA rightly are not a fan of diesel.
Where I live diesel is cheaper, and we pay about 40p a litre for it. Petrol is about 50p.
Don't VW group have previous on this sort of thing: http://www.r8talk.com/forums/5-general-discussion/...
[Audi R8 has a programmed flatspot to help with emissions]
TBH, I thought that all manufacturers did it.
Of course the US case is more devious. As I understand it the car detects the test situation and behaves differently.
