VW fiddling emissions data

reeac

The smaller engine will be working at a higher percentage of its maximum power than will the larger one but both cars require the same power output to get them up the hill and so the amount of fuel consumed should be the same. That's ignoring second order effects such as greater weight of the larger engine, different engine breathing losses etc.

Will the unfortunate motorists who have bought VW diesels have to pay increased vehicle back-tax since they have owned the vehicles ?

Extremely unlikely, VW may get that bill for all the affected vehicles though.

Not when you account for the larger swept volume, pumping losses, friction losses, etc, etc...

So your not going to get it serviced either? If you want to protect the planet you need a tax exempt V8 Range Rover. Must be good for the enviroment because its free tax.

Not due for a couple of years; I don't keep my cars longer than that anyway so I can enjoy the unrestricted oomph for a bit.

Actually, I know several asthma sufferers and in truth I'm pretty annoyed that vee-dub have duped their customers and poisoned everyone.

The defeat device is a double-edged sword.

I have one of those. I regard it as very good for the environment as 44 years on, it is a usable vehicle that hasn't needed to be replaced with a new one several times over. Manufacturing new cars to replace old ones generates huge amounts of pollution and is a drain on the earth's natural resources.

Would not take a car in to VW for anything to be done. So far its a PR thing to save their share value and patch up their reputation. You will be in deep trouble that you don't understand with a misbehaving engine if those Muppets at the dealers mess up the engines fuelling maps. And all they will say is "it conforms to specification. They are like that" and you will not have a leg to stand on. Damaging emissions stand to worsen if they don't get it 100% right.
Remember the whole reason they put the cheat mode in was because they can't make the engine meet the standards while at the same time give acceptable performance. There is no real fix or they would not have needed to cheat in the first place.
If forced to take vehicles in ask what they are going to do? The car is your property. Get it in writing that what ever they say they are going to do will retain the cars performance and economy. We have no way of checking the validity of what they do so we're still the mushrooms in the dark that we have been for the last five years or more. Might even tell you your car did not have the problem when you take it in so you feel great about a free coffee while you sit on their sofas exposed to the new cars in the showroom. VW know all too well that retail success is directly proportional to the number of people that walk through their doors. They are going to make out of this for certain.
I think the best they can do for the environment is leave the cars alone. They are likely no worse than the models built for five years before those that cheat. VW could instead spend the money on some air pollution cleaners that take the damaging nitrous oxide (and a few other things) out of the air in our cities where the cheating polluting cars are doing the most damage. Put a few in each city to clean up the mess being made already and that mess which these cars will make in the future until natural end of life. A kind of old fashioned, bit like being in the stocks but very effective public shaming that corrects the actual wrong doing straight away. Make profit from making a mess you need to clean it up VW. Not patch it up with a PR make over.

Take 2 cars, same body/chassis, same spec's except for one having a smaller - capacity engine. At the same speed, on level ground, the smaller engine has slightly higher RPM. This changes when driving uphill, the larger engine has considerably less RPM, because it does not have to work as hard as the small engine, to maintain the same momentum. It is therefore an inescapable fact, that the smaller engine is always creating more emissions, and thus more pollution.

And yet the motor industry continues to try to make the motoring public believe that a smaller engine is best, by adding complicated electronic devices and controls. At the end of the day, none of it works to escape the fact that the larger engine creates less emissions and can be more economical, than the smaller. This is done of course, to escape VED.

Assuming that higher rpm = worse economy. Does it?

Precisely. They are not going to be fiddling with my car.

If the Government decides its emissions push it into another VED, then VW can pay it.

VW can also compensate me for the miss-selling that is likely to affect the resale value of my car. They can also pay for some dancing girls to regain my trust in their brand .

Clearly it doesn't or my low-revving three litre V6 would be using far less fuel than my 18cc strimmer.
