The EU has in the last couple of weeks released the results of its "Real Driving Emissions" where they put portable emissions measurement systems into cars and drove them on real roads and it shows that for the latest Euro 5 diesels (ie the ones you buy now) the cars tested were 4-7x higher in NOx output than the legislation and in reality were almost no better than 10 years ago.
this is part of a major consultation that they are running with the draft proposals (due to be confirmed next month) that the cycle will be changed to something more representative (WLTC instead of NEDC) and that there should be extra real world tests with the limits being similar to the USA "not To Exceed" limits of 25% IE if the emissions are at any point in time over 25% more than the legal limit the car fails and must be withdrawn from sale.
Several petrol cars were tested and found to be generally passing the limits.
The car manufacturers are expecting the draft to be passed and are frantically rewriting their plans for Euro 6 when the new rules are likely to come into effect. this will mean a huge increase in emissions related systems on diesel (including small cars) which is not going to have a good impact on purchase costs, maintenance costs and fuel consumption
Well said, this always gets overlooked. The fact is modern diesels are still extremely dirty and very harmful. C02 emissions are irrelevant, the amount of NOx and particulates they put out is far too high.this is part of a major consultation that they are running with the draft proposals (due to be confirmed next month) that the cycle will be changed to something more representative (WLTC instead of NEDC) and that there should be extra real world tests with the limits being similar to the USA "not To Exceed" limits of 25% IE if the emissions are at any point in time over 25% more than the legal limit the car fails and must be withdrawn from sale.

I live in central London & work in the city - i drive in to work - this is about 3.0 miles and most of that journey - which can be 20mins-40mins - is spent sitting in congestion. However, I am sitting in a SL with big 5.5l supercharged V8... so every time i pull away i get to hear that great noise and i can still occasionally enjoy gunning it through a tunnel or empty street.
I am only doing about 40 miles per week and so 5mpg or 20mpg doesn't really make any material difference in cash terms. However, I spend a decent amount of actual time in the car each week and a big V8 is massively superior & more enjoyable than just about any diesel I can think of.
So for me, living in a major & congested city makes buying a big engine gas guzzler a no brainer - only if you are doing big mileage on motorways is a diesel worth it.
That's got to be the funniest unintentionally funny thing I've read in ages - you have a 5.5l supercharged V8 putting out, what, nearly 500bhp maybe (you tell me, I don't the model) to average about 9mph on a good day? As a pure made up figure, you probably only get to use about 30hp.I am only doing about 40 miles per week and so 5mpg or 20mpg doesn't really make any material difference in cash terms.

It's very odd to hear that a GT makes more sense in a congested city than on a motorway (I'm obviously thinking of countries where the motorway traffic actually flows).
Please tell me you thrash it round Brands Hatch sometimes, otherwise that's the biggest f
king waste I ever heard of.Edited by xRIEx on Friday 27th April 22:24

It makes him feel good to hear the v8. That's good enough for me. If there's a shortage of v8s i'm sure they'll make some moreIt's very odd to hear that a GT makes more sense in a congested city than on a motorway (I'm obviously of countries where the motorway traffic actually flows).

Yeah, I hate it when the power from the engine goes to actually driving to the wheels- it's much better to use it to drive ancillaries.
Correct. The more wasteful the better just to ps off fake eco s.That way our cars can be overcomplicated and we can have less steering and pedal feel. Isn't that just f
king wonderful?Edited by Motorrad on Friday 27th April 22:32

I used one of those to power my A/C window units when I had a power outage. We're talking about the USA here. I have no idea what your experience of that country is but I'm guessing from the quality of response it isn't based on living there.........In that case, the ultimate choice is one of these:

I've not mentioned anything about the US, I'm just wondering why you think that less power wasted on ancillaries is a bad thing. Racing cars don't run the ancillaries off the engine to avoid the parasitic effect, so why not do the same with road cars?

Because we drive road cars and this thread is about selling people in the US diesel vehicles. You might want to read the origin of this thread there are plenty of others covering people who live in the UK and are being beaten into eco-wheels. ()
I understand that, but I'd still like as much of the engine's power to go to the wheels as possible - if you've bought a performance car for the road, I gather that's the general idea )
. If I'm after the ultimate steering feel, I'll take an unassisted car, and if I want something easier to steer, electric steering will do just fine. Hydraulic power steering us still a big step down in steering feel from unassisted and has parasitic drag too- I see it as the worst of both worlds.
I was just wondering why you were so set against something which ultimately makes the car quicker...

Seriously - I've been reading that the 'end is nigh' for diesels for 30 years now. Seriously.CO2 emissions most definitely are not irrelevant, plus, diesel particulates fall quickly to ground whereas petrol particulates essentially remain airborne and are far more injurious to health. Then there is the issues with benzene in petrol.
