News on Monday morning that Ford is spending £190 million to expand Dagenham production of 2.0-litre turbodiesels for use in both vans and cars – and has won an £8.9 million grant from the government’s Regional Growth Fund into the bargain – makes certain elements of both the daily media and the political classes look rather silly. And confuses many people.
For many weekends recently, the Sunday papers have published stories from academic research sources to the effect that the decades of encouragement we’ve had to buy diesel cars – mainly because, on balance, they’re cleaner – is completely wrong.
The combination of exhaust particulates and oxides of nitrogen they emit, not well enough measured in current official tests, is allegedly killing both us and our children. London mayor Boris Johnson has been vocal about the damage being done by diesels – yet David Cameron and Vince Cable deal out financial incentives to encourage further production, in outer London, regardless.
What’s the truth, then? The overall situation is simple, but poorly explained. The official tests are indeed inadequate. They need urgent overhaul to better measure particulates and nitrogen oxides, and in typical, not laboratory use.
Equally, the activists need to acknowledge that the problem is on its way to being defeated: the Euro 6 standards that latest diesels are required to meet by September but many meet now – admittedly measured in the old way – are already clean enough to pass the standards Boris has in mind for his 2017 ultra low-emission zone.
The Euro 6 standards are particularly strict on especially on particulates and NOx, though neither the mayor’s people nor the activists seem inclined to acknowledge the progress.
The desirable situation, as usual, sits between extremes. The tests need revision, and soon. Those with diesels with exhaust standards below Euro 6 need to keep them out of polluted and congested areas — preparatory to swapping them as soon as possible for something cleaner.
And by the way, Boris and company could bite the bullet and rid the metropolis of the many ancient taxi diesels they still allow to ply our inner city, individually pumping out more exhaust rubbish than any other 20 cars of the past decade. Why they’re still allowed is beyond us all.
Bottom line? Well done Ford for upping production of ultra-clean diesels. Well done the government for encouraging them to do it. These engines will surely replace dirtier ones. Well done the activists, also, for continuing to point out the grievous inadequacies of current testing, even if you are seeing fit to leave out a part of the story not convenient to your narrative.

What progress?
Well, there is a very good reason for that. If you read the ICCT report it shows Euro 6 compliant diesel cars breaking the NOx emission limits by an average factor of 7 taking them beyond the limits set by the Euro 3 standard in 2000.
So apparently in the last 14 years there has been no progress.
Thank heavens I no longer
As a former Farmer (Just North of London), I cannot abide British politicians.
All our farm machines were Diesel powered and MUST remain so. I am a Petrol head regarding sporting machinery - but for regular transport, I will not swap our A6 3ltr Diesels.
A previous Petrol powered 5 series was positively the worst cat I have ever owned (in a fleet of 32)
The problem seems to be older
Maybe we need more frequent 'smog tests', like an MOT as normal, and a 6 monthly emissions test?
Saying that, I have two diesels, one private and one a company car. The former because of fuel costs, and that because of fuel and VED tax levied by the government. The latter because my company car scheme limits to below 130 grammes/Kilometre, and I pay tax on the Co2. There isn't much you can get with <130 G/K that'll be much good for 30,000 miles a year. The government is also removing the diesel tax penalty for company cars...
People bought cars on the basis of the costs and tax regime in place, it's unfair to now run around banning them and expecting to spend money on new cars to suit the current whim of government.
By all means state (as Boris is) that from a certain date cars above a certain limit cannot enter certain places so people have time to adjust.
The diesel avenue was stupid, so was using Co2 as a primary measure, but that isn't the fault of the average car user. We never chose the criteria, and we don't have money to just get rid of virtually worthless cars to buy a petrol one now someone decided that's today's flavour.
