As @nick says its a diesel ban that's coming first. Last 2 years when pollution is bad in Paris they have operated an alternative odd/even registration number system for driving in the city. Also all old classics (eg your MGB / E-type) are now permanently banned. We now have a "vignette" system with a colour coded disc based on how polluting the car is and it's clear they will use that to limit access. The Mayor has openly stated old diesels will be permanently excluded if she gets her way in the future. (Nite she is also closing roads making congestion and pollution worse 😐 )
IMO the writing is on the wall for diesels certainly in big cities. If we where still living in central London I'd buy a Hybrid for the congestion charge savings and as "insurance" against any future rule changes
EDIT: we are in the market for a new (used) car and it's tough to find good petrol models as for so long diesel has made up so much of the sales figures.
City driving's skewing this a lot. You can ban my diesel from city centres if you like, it's only been in a city centre once in the last 5 years. It's a big deal for some people of course but not for all.
There are positives and negatives to diesel. They produce more of some pollutants but less of others, which is the issue.
I'd like to know real world NOx figures for SCR (aka AdBlue) equipped diesels.
this gap is also now closing with the introduction of smaller petrol engines that are lighter and are more economical.
Well, you can also get smaller lighter diesels too.
Flaperon, that's total nonsense. Diesel cars, even Euro 6, are way worse for NOx than petrol. Plenty of research done to show this.
Over exaggeration much?

I wouldn't say that 0.02mg/km is way worse. Certainly not as good but diesels still emit half as much permissible CO2 as petrols. Note that I'm being very careful to distinguish between the NOx [b]generated[/b] and those [b]emitted[/b]. The generated NOx are dealt with in the EGR system (which then has a knock on effect of increased particulates so DPF is fitted) and so can be mitigated against.
And yes, city driving exacerbates things as engines don't get up to a good temperature to reduce particulates (ironically cooler engines will generate less NOx).
I think it would depend on your intended use. If you're going to be pootling about town, I personally would avoid a diesel if I had the choice.But for up and down the motorway, crack on.
Pretty much this.
My take on this so far is that (generally) diesel engines produce a lot more Nitrous Oxides than petrol engines. A lot of the statistics used to highlight the difference in the amount of NOX produced do not take into account that diesel engines are on average bigger and that newer diesel engines that use AdBlue technology are closing this gap significantly.On the flip side of this, petrol cars (generally) produce more Carbon Dioxides than their diesel counterparts but this gap is also now closing with the introduction of smaller petrol engines that are lighter and are more economical.
So when it comes to looking for a new car I should be looking to either choose a newer diesel engine or a smaller petrol engine that is as economical as possible. Regardless of the number of miles covered, is this not the best way to go?
What are you trying to achieve? Better economy? Less pollution? And what driving are you doing - city, motorway or mixed?
We've just replaced an '06 Focus 1.8tdci with a '16 C220D and it gets pretty much the same mpg, but significantly less particulates - the Focus used to blow a huge cloud out the back when accelerating hard which was visible in the mirror in headlights of cars behind, the Merc has no discernible cloud at all.
I'd never drive into town, its just not worth it - that's what bicycles and public transport are for. Fortunately I've just found the AdBlue tank level as the manual helpfully suggests two very different capacities - one which means refilling every 5,000 miles, and the other every 15,000.
The next car will certainly be different, probably solely electric or electric drive with a small infernal combustion for range enhancement.
Any car more than 30 years old and registered as a collectors car can be driven around Paris, Jamba. So you can still trundle down Les champs in your E-type.
Paris is one of the cities that clearly demonstrate how useless the E3/4/5 and even E6 are in real driving conditions when people clog it away from the lights. Pollution in Paris has not gone down as the older more polluting diesels have gone to the breakers because the newer standards make next to no difference when diesel cars are driven hard.
If they really do start banning diesels from city centres then the shit really will hit the fan . Virtually every lorry or delivery van is diesel and when did the petrol engine become environmentally friendly anyhow ?
They didn't, but we just found out that diesel emissions are far far worse for our health than we thought.
However our 1.2TSI petrol stop start Golf easily does over 50mpg.
There isn't really a viable alternative yet for lorries (except perhaps they could go hybrid around town like London busses). There are viable alternatives for diesel cars.
Diesels are banned in Tokyo, even their trucks run on petrol.
Is "nice place to be" the new "making progress"?
esselgruntfuttock - Member
I'd stick to a diesel. I can't be arsed changing plugs, points, condensers, rotor arms & distributor caps when they conk out, not to mention setting the dwell angle
I'm hoping this was tongue in cheek as other than the plugs, none of these are present in a modern car.
What? So does that mean I can sell my dwell meter?
Do they still do 4* petrol?
Is "nice place to be" the new "making progress"?
No, just another way of saying 'it's a nice car'.

I take it everyone in Paris drives a new car then?
non of your points convinced me anyone. picking the big planet killer up on Saturday.
I reasoned that the amount of cycling I do must offset the little bit of driving I do.
makes sense eh........ 😆
You may as well be comfy Ton, speshly being the state your body's in! 😆
bastard............... 😆
Sqirrelking, I'm repeating the results reported. A drop in NOX and soot was expected as the Euro 4/5/6 cars replaced older diesels. In eight years half the cars on the road get replaced so we should be seeing the benefits of at least E5. However, the levels of NOX are still going up. This is exactly what prompted the Americans to start real world testing which led to them discovering VW's cheat and the whole dieselgate saga. E6 is still a fudge. Drive an E6 diesel hard from cold and it's still a filthy beast - the test still doesn't do that.
Just about to replace my current diesel with another second hand diesel. I do 20,000+ miles a year and its generally 800 every other weekend in two journeys of 400 each way. I don't drive into a large city centre very often and have to park on the street living in a flat, so for me diesel is still the right tool for the job but will embrace the change when it comes and meets my needs.
My last 3 cars have been diesel; the £400 a year fuel savings seemed to make it worthwhile. I am starting to change my mind though: The newer diesels might have fewer emissions but they also have very expensive components that are as likely as not to need replaced in the first 3 years. If you have to replace any of the following: Injectors, commonrail pump, dpf, dmf or egr then your fuel savings over several years will soon disappear.
they also have very expensive components that are as likely as not to need replaced in the first 3 years
I don't think that's true. 50% failure rate in three years?
"As likely as not" is technically 50%, but not necessarily that precise for the purposes of rhetoric! 🙂
Diesel's are responsible for environmental cancers and people are trying to reduce their use. If you have the choice you should buy a petrol car.
So what has ton bought? did I miss that?
Interesting. The family car we are looking at is £800 more expensive in petrol form and does 20mpg less on average (manufacturers figures) and has a higher VED band. As we lessen the school runs and the ratio turns to longer journeys and lower the mileage, its a real quandary which to go for. We are outer London and would never drive in, but the environmental factor is an issue that to me although massively offset by everyone else emissions is something I cant change - although of course if everybody thought like that etc...
What I find odd is we are all affected by cancer..Often threads on here being angry at it. Yet, when it comes to taking a financial hit to do our bit to help reduce number of cancer victims, we justify not doing it and still opt to drive diesel's.
FYI, I drive petrol. Diesel is simply off the cards for me now.
Modern Diesels are very clean and no comparison to the smokey oil burners of old - my 2016 Vauxhall Insignia 1.6 CDTi EcoFlex Estate produces 99g/km of emissions and is Zero road tax, 50mpg around town and 70 mpg on a run AND you can get 2 mountain bikes in the back.
Compare that to a petrol engine above 1.6 and with similar room inside,then tell me who's damaging the environment.
Did I mention that it's for sale? 😀
In my mind, domestic diesel vehicles shouldn't be the first target, it should be commercial vehicles. 14% of Nox pollution in the UK comes from transportation but it does get released at sensitive high density areas, so why not target the buses, taxi's, vans and lorries that drive at low speed's and idle in cities, surely this would make a far higher dent in the problem than someone driving their diesel in rural areas or on motorways getting penalised

None of those are very likely to fail in 3 years (and dmfs are appearing now in petrol cars. DPFs are a pain in the arse mind.
Do SCR/AdBlue cars have EGR?

But this is about NOx not CO2. How much NOx does it emit? Do you know?
@rivingtonbike...What makes you convinced new diesel's are cleaner? The car companies have been caught lying through their arses regards their emissions figures.

All you've done there is quote the Euro emission limits, which as we know, bear no relation to reality. Recent research shows that a Euro 6 diesel car will typically emit 2-3 times the prescribed value. So when I say "way more than petrol", I do so advisedly.
Secondly, your claim that diesel is "half the CO2" of petrol is curious, seeing as CO2 values are not part of the Euro standard.
In my mind, domestic diesel vehicles shouldn't be the first target, it should be commercial vehicles.
Commercial vehicles show much better compliance with Euro standards. In fact, I'm told that some Euro6 buses emit the same amount of NOx as Euro6 cars - when you consider the number of people they can carry that's hugely impressive. Apparently, the better performance is due to the use of real-world testing for commercial vehicles, versus (easily gamed) laboratory testing for cars.
It's simple. People justify diesel because it saves money. The evidence is out there for all to see about how diesel contributes to cancer etc. All it would take is to own one less bike (for many people on this forum) to swap to petrol and not be hurt by the financial impact of the swap. Not hard choice really, to make a positive contribution to the health and well-being of our friends, family and fellow humans.
There's a bit more to this though. You get a given amount of petrol and diesel from crude oil. So if we weren't using the diesel it would still be being extracted. You can perhaps do other thing with it, but more petrol usage means more crude to be extracted.
So if we don't burn it, we should do something else valuable with it. And then try and figure out how to make the petrol go further.
People justify diesel because it saves money.
I originally bought one to save fuel for environmental purposes. Which it does, and did even more so in 2003. Then a second diesel I bought because I liked driving it, and I was still able to get 40-50% more mpg than the equivalent petrol.
However now with TFSI engines and hybrids available, it's a bit different. Strongly considering TFSI next time.
It's simple. People justify diesel because it saves money.
Not necessarily. My annual mileage is low enough for the cost saving to be trivial. I bought a diesel car some years ago because of the CO2 saving and I believed the emissions abatement technology was sufficiently advanced to trivialize the local air quality concerns. That belief was evidently false, which is why my car will be traded in for a petrol once I've saved up enough cash.

This plus the Govt pushed us this way, thru tax changes and their overall message (basically through the late 90's right until th elast couple of years).
Excuse the pun, but it now seems successive Governments have been asleep at the wheel when it comes to taxation on diesels. I have one as a company car and that's because of fuel efficiency, hire costs and BIK. Mainly the latter. When did we start to understand the localised impacts of NOx? It's not like its a new thing but it certainly hasn't been publicised as much as in the last 12 months or so. Co2 emissions are still used as part of the VED and BIK calculations but no NOx figures used AFAIK. Still, you can't expect this Government to be environmental guardians I suppose.
Anyway Ton, what colour is it?
Anyway Ton, what colour is it?
black. with black leather interior, and old person heated seats.
bought for comfort and the ability to put 2 bikes in the back.
Have you bought a Hackney Carriage then? Nowt wrong with heated seats either.
When did we start to understand the localised impacts of NOx?
I was taught the risk and potential impacts of SOx COx and NOx emissions during my A-Levels between 1995-97. Obviously this information predated that by decades either through study of the health of workers in heavy industry or the work on climate change pioneered by UEA in the 1970's.
Those quoted Euro emissions standards still look pretty bad don't they? A modern diesel is comparable to a 12 year old petrol car, or a third worse than a new petrol car.
Picking something fairly generic:
[url= http://www.nextgreencar.com/emissions/make-model/ford/focus/ ]http://www.nextgreencar.com/emissions/make-model/ford/focus/[/url]
Petrol are 21-31, diesel are 40-75. I do short journeys, so avoided diesel personally. I'd also be fearful of huge taxation being added to push people towards efficient petrols in the future, be that on a change to VED or diesel I'm not sure.*
* that said, the new 2017 VED system seems to suggest the opposite, oh well. Buying a 1.0 Fiesta for 5 years got more expensive, buying a 5 litre Mustang for the same period got cheaper. Hmm!
Using that ^^ the X1 auto we want emits less NOX via the 2.0d than the 2.0i
have you ever tried buying a car to suit a 5ft lady and a 6ft 4'' gorilla?
Transporter.
I prefer the drive of a diesel anyway. Petrol (and modern diesels to some extent) are all whiz and no tug.
I like to think I'm a greeny and I think the environmental guff is all a scam. Diesels cough out soot and NOx, petrols CO. Choose your poison. You could of course get a diesel and run it on cooking oil to cut your emissions? (or could you run a normal petrol on ethanol if you could get hold of it? I don't actually know). I want an electric next. Of course all, including the electrics, leave brake dust and tyre particles everywhere. [tangent/]
petrols CO
CO is pretty harmless to the environment though isn't it? Just harmful in your lungs in high concentrations...?
