I first heard about this a couple of years ago-when Gordon Brown set tax tariffs according to a cars' "green" credentials, he was misinformed as to diesels- apparently they are very bad pollutants.

There has been talk of banning them completely, but in the meantime, use of them may be discouraged by increasing parking charges, etc (as in London).

This is worth bearing in mind as diesel estates are popular model transporters!https://www.theguardian.com/environment/2017/jan/27/westminster-council-first-charge-extra-park-diesel-cars-air-pollution-emissions

I got a whiff of this happening 18 months or so back, and, after 24 years of diesel motoring I switched back to petrol. Again, to be on the safe side I chose one of the newer eco orientated models, a Ford Focus 1.0 three cylinder. I seem to be down about 8 mpg or so over the diesel I had, but I feel that's a small price to pay now as I'm no longer working full time and not doing the mileage I previously did.....

Weird, one time, they said petrol was bad and encouraged drivers to go to diesel, now they say diesel is bad and encourage drivers to back to petrol. Crazy!

I had petrol while back and hated diesel cars, but after driving the newer CDTi engines - loads of power and torque - for towing caravans. Petrol cars are fast, but lack pulling power, unless you go big.

Then the fuel economy, I have 2 Vectra Estates, both diesel, one is a 1,9CDTI 16v and gives 40mpg, but strangely enough, the other is a 3.0l 24v CDTi V^, giving 184BHP. It gives around 46 MPG, even gunning it. Big engines use less, and the thought of towing a caravan with a 1.0l 3 cylinder engine... oooh!

Both cars have cats and a DPF filters, and don't smoke - as long as all parts are working ok.

It may only be a one litre Paul, but with 125 bhp, six gears, and a near 120mph top whack, it's plenty enough for me. I get around 44mpg no matter what I seem to do. My Skoda 1.6 diesel returned around 52mpg. Luckily I traded it in just a few weeks prior to the emissions *thing* blowing up. 

And I've no interest in owning a caravan, so that's not an issue for me either.

Problem is with small engines, they have to be thrashed to get anything out of them. It's only the turbo that gives it the extra power. Like model engines, an engine is best running at around 50-60 power, not at tick-over or at 100% all the time.

Tell, me, I blew two works' van engines, when the pitiful 57 hp 1.9 naturally aspirated diesel engine was being over taken on the M-way by full laden Morrisons trucks.

Thrashed? I never take it beyond 3500 rpm. It develops it's maximum torque at 1800rpm, so I don't  need to push it hard. Clearly Paul, you've never driven a new 1.0 litre Focus.....

As I said earlier, I'd had diesel cars for 24 years. I wasn't going to buy just any old petrol job. It had to be an exceptionally good one, and the 3 cylinder Ford engine is.......

I am keen to know if there's long life being designed with those small capacity engines?

Live hard & fast? and keep garages happy with replacing the engines 😡

In the old days, it makes sense to have larger engines in order to spread the load output.

Twenty years ago the government only looked at the CO2 figure and none of the other pollutants. Developments in Diesel technology using higher pressures and smaller injector nozzles ( to further reduce the CO2) mean the soot particles are now so small they can pass straight through the lung membranes into the blood stream. Hence the development of DPF ( Diesel Particulate Filter) systems. Trust me, these are the work of the devil, if you do motorway work they are fine, but drive a modern Diesel mainly in town and you are in for a world of pain. Going back to petrol can only be a good thing as far as I'm concerned. The small amount of money you save with Diesel is just not enough to cover my bill if you need new injectors or a high pressure pump. The little Peugeot Citroen Diesel quite commonly destroys its high pressure pump and contaminates its injectors in the process, a couple of grands worth of parts and shed loads of labour to fit.

I can't answer that one Keith. I generally keep my cars for three to four years, covering maybe 6k miles per year, so it isn't likely to impact on my ownership term.

Shaunie

A good point re: newer diesels. The adblue thing will doubtless catch quite a few out too. As you say, unless you're covering a decent mileage, with the majority of it on faster roads, you'll clog up the DPF......

I have an older (08 Reg) Diesel VW Sharan automatic at the moment, no DPF.

When I eventually get rid of it I will be going to petrol or possibly electric if Tesla keep making improvements.

Isn't it ironic that Germany inverted the diesel engine and will probably be the first country to ban use of it, entirely? Just sayin'

Banning diesel cars in city centres? What about the pollution from diesel taxis, buses tradesmen's vans and delivery lorries?

Let's not forget the majority of shipping vessels in the world which are chucking out tonnes of diesel pollution on an hourly basis.

Yet again the private motorist has to suffer at the behest of our wonderful politicians. Heck, it wasn't too long ago the government were actively encouraging us to buy diesel cars!

Personally, I drive a Škoda 1.6 diesel (with DPF) to and from work, and after 42000 miles from new I've yet to have any issues. But then I've always used fuel with a low bio content, BP.

Well said. The car I drive is only available as a diesel.

Banning diesel cars will make very little difference to the environment as the bulk of the pollution comes from commercial use.

And what happened to the hydrogen fuel cell?

I am sure the hydrogen fuel cell will never happen.

It's not just parking you should worry about. Here in Essex there is a Low Emission Zone that starts just inside the M25 - at the moment it only bans old vans and lorries but probably with a stroke of a pen the Mayor or someone could change that to other diesel vehicles.

It already has WF. Toyota have a 100% powered hydrogen fuel cell car already available in certain markets.

What needs to happen now though, is a vastly increased range with electric cars. We have to start somewhere of course, and the current (pun?) examples have made a small impact. Once the manufacturers and battery suppliers can extract 500+ miles from a single charge, and there is a plentiful charging infrastructure in place, then it'll all take off big style. But at the moment no one organisation is willing to finance it all to the degree required until those sales increase dramatically.

We're pretty much in the same place as we were when the internal combustion engine began to be used to power horseless carriages. There were no petrol stations, and there needed to be. It all happened eventually of course, and that'll be the way with electric cars. But not for a few years yet.......

I don't usually keep my cars long as well, but had to replace twice my cars engines due to long distance commute being seconded to a far away workplace for 3 long years. Those are petrol.

I currently have a VW up! as a runabout and don't plan to keep it for years, but so far it is is reliable and I am happy and have my rear seats folded to have a largish space, but feel I will soon outgrow and need a bigger car.

The urgent problem is the micro soot particles which do come from the small diesels in private cars The soot from big commercial diesels is not so harmful to humans.

But then we are now told not to brown toast to much due too the formation of acrylamidea!

All Diesel fuel by law is now 5% BioEthanol. A bit like government mandated coin clipping really as it coincidentally give around 5% less mpg.

Don't worry about Adblue, Peugeot Citroen cars use Eolys at around £28 a litre and you usually need a refill of 4 litres at about 75000 miles as well as a DPF washout.

Shaunie.

Since all HGVs and most LGVs are diesel powered, all farm machinery is diesel powered (and what emissions do they need to meet?), virtually all ships are diesel powered how much difference will banning diesel engines in private cars make? Looks like another bit of gesture politics.
