As I understand it the software for engine management when it detected a test unit connected to it changed the parameters of the engine to give a lower carbon emission figure.
You are going to get caught sooner or later!

 >>:-( So VW have been found out fiddling the emissions figures,clever software that can tell whether the car is on the road or on a rolling road on test, giving a lower figure for the latter,this could bankrupt VW with all the damage claims as all the lawyers are circling around like Vultures and soon all the adds will be on your telly like the PPI scandal,is this just the tip of the iceberg? have all the car companies been doing this?could this be the end of many famous car makes?whatever the outcome this story is going to run and run.If you have one of these cars it will be recalled and the software altered which means the performance will be a lot poorer and you will use a lot more fuel to keep the car emissions correct,if I a betting man I would put my money on that they are not the only ones and that governments will cover a lot of this up to protect these important industries and the jobs involved,having had many new cars I have never been able to get anywhere near the fuel figures they claim no matter how careful I drive so this just another of their false information their pump out to the public,anyone have any other views on this story.....Ray >>:-(

This is a very complex issue, not necessarily centred on the transport industry for an answer  >>:-(

Should we ask all commuters to walk?....would we then need to ask them to pass a minimal or acceptable level of a GAS emission's test from bodily functions  {-) to permit them to walk on the road?

If a walking commuter was found to be passing an unacceptable level of CO2 or C3 O4...during their jolly walk to work.......who would  :police: this?....  %)........

I think that the real root of the problem is that these tests are done in a lab rather than out on a road. It shouldn't be beyond the wit of man to contrive a "standard" section of real road (i.e, no gradient, same surface and camber etc) on which all cars can be tested at a number of different road speeds. There are already portable gas analysers out there which can be connected to the exhaust of a moving car; I watched a video of one on the BBC News website just yesterday. As for other manufacturers cheating in the same way, I would be frankly amazed if they weren't all at it to some degree; it's too tempting.
I stopped buying diesels only because I wanted a particular model of car and the local dealer had an ex-demo one at a very good price - but it was a petrol-engined model. These days I only do a fraction of the mileage I used to do when at work, so the fuel consumption isn't that important. As for emissions, I have a problem when comparing those of a 2-litre diesel car with a forty-foot articulated HGV. Incidentally, both my car and Elizabeth's are supposed to do a combined MPG of over 50, yet neither of us can get more than 36.
You're daft if you believe a car salesman's blarney, so why have any more faith in the car manufacturer? Capitalism has made cynics of us all.

A huge proportion of your mpg figures come directly from the way you drive and where you live - I live on a hill so almost all my cold-starts are driving up a long incline.

My car has a computer that displays all sorts of stuff including trip mpg.

I normally get around 28mpg but on a run, it can be 48mpg - when my wife borrows the car, it drops to 25mpg and 40mpg doing the same journeys.

Excerpt
The company didn’t explain that it was taking the action in hopes of satisfying government regulators, who were growing increasingly skeptical about the reason for discrepancies between laboratory emissions test results and real world pollution from Volkswagen’s diesel cars.

Which? Magazine has been on the case of differences between real world figures and manufacturers figures for a while. It was reported that the VW Golf had one of the  biggest discrepancies.


Concerns over true pollution levels have also spread to fuel consumption, with the consumer group Which? having long reported discrepancies between official miles per gallon test figures and their own results, with the VW Golf being the second-worst offender in their research. http://www.theguardian.com/business/2015/sep/24/vw-scandal-car-giant-faces-uk-legal-claims (http://www.theguardian.com/business/2015/sep/24/vw-scandal-car-giant-faces-uk-legal-claims)

It's nothing new, its happened for years in one form or another.

My Suzuki Hayabusa ( Guinness Records, fastest ever road bike) had similar mapped into its ecu. Between 4900 rpm and 5100rpm the ecu automatically leaned out the fuel/air mixture to conform with mot regulations which are read on a bike at a steady 5000rpm. Outside of that range normal service was resumed and missile like acceleration new no bounds.

What's worse now is "BIO DIESEL" That's made from anything that can be broken down , used chip /  curry / fish cooking oils and rapeseed oils  , if you think Diesels bad wait 'til you get a lungful of this stuff  %%  ,quite a few of the Heavy Hauliers are using BioDiesel now , one of our Hauliers was BANNED from backing his wagons into the loading bays ,  :police:  not only was the 'aroma' appalling everything seemed to get an oily sheen on it  O0

Many motorists are more than happy to remove their diesel particulate filter to improve performance and stop those annoying warning lights. They don't care that this means that all the crud is just blown out of the exhaust instead, only that they hope that removal of the DPF will not be noticed at the next MOT inspection.
Diesels have simply got too complicated with all the bolted on sensors and emissions gadgets, all of which cost an arm and a leg to replace when they go wrong. I have switched back to petrol now. Electric cars will not become practical unles there is a breakthrough in battery technology to give them a range of at least 300 miles on a charge.
Colin
Title: Re: VW scandal
Post by: Unsinkable 2 on September 24, 2015, 10:28:09 pm
This is a great debate and one which many a good point has already been mentioned, one of which really intrests me........ Electric cars, bikes etc..... Colin, I half agree with you, I understand that people want electric cars that do decent distances on a single charge but it's not a breakthrough in battery technology that is preventing this happening it's the opposite!
 
Battery technology is being improved upon all the time. Imagine this, you buy a state of the art electric car, it does 300 km per charge and cost you 15000 pounds to buy. One year later technology has increased that range to 500 km but the new battery is incompatible with your present system, your 12 month old car would be almost worthless as everyone knows that another 12 months down the line there will be a new battery and better range. SO, what needs to be done is some sort of agreement on the battery size or size and shape throughout the industry so that any new technology can be fitted into any old car regardless of make.


When horses got replaced by internal combustion people must have laughed ha but we're do you buy this petrol stuff from? But even with the advances in technology it's still the same petrol you put into a Ferrari as you put into a ford pop!..... Ok give or take but you know what I'm saying. If I buy an electric car today that does 100 km on its present set up I want to know that the same car will be still usable in 10 or 20 years with its latest battery update. It may not be as good as a future car with the same battery (like comparing MPG on an Escort Mk1 with a modern day focus but at least they both run on modern fuels)


If manufacturers can't agree between themselves about battery specs then they will all end up with different size and shape batteries none of which will be transferable and all of which will be soon outdated. Unless you can afford to lose so much money who is going to do it?



I would love to buy a new electric car tomorrow but come 12months when the new batteries double the range and I can't sell mine for even half the price, or after 3 years it would be like being stuck with a 3 year old Ford Focus that does 8 mpg when the new one does 70.


So what do we think, battery size and shape agreements throughout the industry, or guaranteed buy back price on used vehicles by vendors?


Not a rant just a criticism of how things are being handled by manufacturers with modern technology.  U2

Post by: Stavros on September 24, 2015, 10:47:51 pm
Colin in no means am I having a pop at what you have said BUT ......Our Audi recently had a particulate filter problem at 70000 miles...had a quote off audi to replace said exhaust piece      £1480 and they wanted it  for 2 days ........So we had the filter removed and a total remap of the Ecu cost £400 Done in Half a day........Joke is not only the company I used and Audi would have had to remove the said exhaust and replace it.

MMMMM odd isnt it  the last 2 Mot emmisions were compared to the one carried out yesterday and the Emissions are LOWER than the previous 2 ad an actual power increase of 28 BHP and the MPG has actually gone up by 6MPG.

The thing is by removing the DPF the engine is now running far more efficient and so will not be giving so much pollutions into the atmosphere.

The std Mot test to check if a DPF is fitted is purely visual they can not fail it if the box has bee rewelded up...ad as long as it passes the stationary test of reving up to 2500rpm and not going higher without dipping the clutch the it is a Pass..........

I must admit I was rather sceptical about this process till I had it done but it works

Biggest thing this weekend that made me chuckle was whilst working doing a road closure  was when a chap stopped me and asked where the nearest Audi dealer was as he has this .....in his own words..I got bleep bleep bleep particulate filter thingy or something up on my dash and I got NO POWER....... So being the kind person I am told him what to do .....drive at 2k constant down the road on his way home to Manchester and it would clear.
Thing is this particular Audi was only 6 days old and had covered 1500 miles....WOULDT like to be the salesman in his local dealership o Monday morning as he was taking it back for his money back !!!!!!!!!!!!!!

This to me really summed up the old PARTICULATE FILTER SAGA

Stavros, my brother told me the same thing, drive at constant Revs for 10 mins and something heats up and 'burns' the filter clean. I don't know where all the burnt bits go but it works, I set my cruise control on the way to work and clear it. I have been told that if you change the revs the 10 minute timer resets and you have to start again? You can hear it start on some cars apparently but who knows, owners, garage mechanics, lying manufacturers?...........

Title: Re: VW scandal
Post by: Colin Bishop on September 25, 2015, 06:23:54 am
I can certainly understand why people have their DPFs removed, it is way cheaper as Dave says and it does work. However it does make emissions worse overall because there is no filter for the soot despite the engine running more efficiently. Also there was a recent report in one of the papers that the authorities are well aware of the practice and that the MOT is likely to be tightened up in the next year or so to check the level of particulate emissions as well as for NO2.
The main reason that the filter doesn't clear or 'regenerate' is that the engine doesn't get hot enough if the car is mainly used for shortish runs,. It needs a blast down the motorway for 20 minutes or so at least once a week to keep the DPF clear and not everyone does that. The DPF is an engineering 'kludge' and it is the customer who is literally paying the price.

Title: Re: VW scandal
Post by: Colin Bishop on September 25, 2015, 09:18:37 am
None really as the engine never fully warms up and you don't see the mpg benefit until it does. It just costs a lot more to buy and is likely to land you with expensive bills. Diesels are most suited to those who rack up motorway mileage. If you do under 10k per year then a petrol is a no brainer.

No advantage at all Dave....joke is ours didnt do short journies ok yes some days it does fair comment but on the whole it does dual carrigeway and motor way miles as well......the fact of the matter is simple really as Colin has put it ....these so called soot filters are a sheer money making racket to keep the greenies happy.
But does it......all it does is to cause more problems..Why...simple really....you now need specialist chemicals to clean the exhausts up so the metal can be recycled .....more enviromental issues.
Borris Johnson with his darned immision free zones etc have a lot to ans for....next thing we will be back to a horse and cart.....Oh NO  we cant as the green idiots would soon be up in arms about all the horse dung......so we would need a horse particulate filter and lord above if one happened to block up !!!!!!!!

Horses that pull tourist carriages are usually fitted with both nose and backside bags but at least the contents of the latter can be productively used as fertiliser - very organic!
DPFs are poor engineering solutions. Eventually we will have either electric or hydrogen and the cars will drive themselves! The idea of standard battery sizes is a very good one although you would probably need several standard sizes to fit different vehicle sizes.

Thanks, chaps. Looks like my having to buy a petrol Verso instead of the 2.2 diesel which I really wanted was a lucky break. I doubt if either of us will be looking for another car - certainly not in the immediate future - but as/when/if we do there's little chance it would be a diesel and no chance it would be a VW. I've always been told they're unhappy about going past filling stations!

Yet again the topic of Batt powered cars...MMMM lets see....more electricity will need to be produced to charge said vehicle..MORE pollution due to the fact of the power stations having to work harder....more eviromental Issuse.

Thing is Colin I agree...Heck thats a first !!!!!! Something has to be done,...Biggest joke of all this is a friend of mine works in a main dealer who have these dual cars....Petrol and electric and the biggest complaint of the owners is the rate of degrigation of the tyres....far less Miles /tyre compared to a std petrol or even diesel due to the sheer weight of the car......Hence why they have a short duration......a NO win situation...FIX one problem and low and behold another surfaces.

I organised an electric car motor show last year - it was very interesting.

Some dealers were very helpful and supplied cars and staff to demo (BMW, Renault, Mitsubishi & Nissan) - some dealers just supplied cars (Vauxhall/GM) - some dealers couldn't be bothered (most notably VW) even though they had electric demonstrators at their dealership - other dealers were interested but had no demonstrators (Toyota - they only have customer's cars) and other manufacturers wanted to attend but their only demonstrators were elswhere (Tesla)
Other's advertised electric cars but admitted they cannot sell them (Audi)
Most interesting was Citroen & Honda who denied they made electric cars!

I've done a lot of research into the tech and it seems that most of the scare stories are false (old wive's tails) just like when catalytic converters were introduced.
Most of the advances in the last few years are from the software looking after the braking/charging/power delivery - not the battery capacity.
Also, there is a trick that can rejuvinate the batteries back to 95% capacity when their performance starts to drop off after about 8 years driving. This will be part of the dealer service protocol.

The electric cars with the range-extenders (BMW i3 & Chevy Volt) have unlimited range - they just switch to petrol or diesel when the battery is used up which recharges the battery on the move - the fossil fuel motor is not normally connected to the wheels (although the Volt has a very complicated system that can allow the engine to connect to the wheels).

The Hybrids just drop back to fossil fuels when their batteries run down.

For 90% of drivers, an electric car would be more than adequate.

I organised an electric car motor show last year - it was very interesting.

Some dealers were very helpful and supplied cars and staff to demo (BMW, Renault, Mitsubishi & Nissan) - some dealers just supplied cars (Vauxhall/GM) - some dealers couldn't be bothered (most notably VW) even though they had electric demonstrators at their dealership - other dealers were interested but had no demonstrators (Toyota - they only have customer's cars) and other manufacturers wanted to attend but their only demonstrators were elswhere (Tesla)
Other's advertised electric cars but admitted they cannot sell them (Audi)
Most interesting was Citroen & Honda who denied they made electric cars!

I've done a lot of research into the tech and it seems that most of the scare stories are false (old wive's tails) just like when catalytic converters were introduced.
Most of the advances in the last few years are from the software looking after the braking/charging/power delivery - not the battery capacity.
Also, there is a trick that can rejuvinate the batteries back to 95% capacity when their performance starts to drop off after about 8 years driving. This will be part of the dealer service protocol.

The electric cars with the range-extenders (BMW i3 & Chevy Volt) have unlimited range - they just switch to petrol or diesel when the battery is used up which recharges the battery on the move - the fossil fuel motor is not normally connected to the wheels (although the Volt has a very complicated system that can allow the engine to connect to the wheels).

The Hybrids just drop back to fossil fuels when their batteries run down.

For 90% of drivers, an electric car would be more than adequate.


Isn't the VX Ampera another that can charge on the go? (uses the same tech as the Volt)

The Ampera is a re-badged Chevy Volt - very odd to drive - the engine periodically starts & stops and runs at constant revs charging the battery while you drive and change speed and start & stop - I suppose you get used to it. Nice car.

Volkswagen have announced a new diesel car offering lowest-ever emissions.
Regulators have queried the use of the petrol car towing it.
Batteries have never, and quite probably never will be, a dense enough form of energy storage to give adequate range for use on a daily basis unless the only journeys are going to be a fairly short commute.  Then there are the problems of recharge time and life expectancy of the actual battery.
Hybrids are only a sort of answer.  You have to lug around a heavy battery and effectively a portable generator and its fuel supply which is unlikely to ever be as efficient as a mains supply.  It can't be as efficient as a purely fuel installation because of the extra weight being hauled, even if it is easier to drive and the electric drive doesn't pollute in the right circumstances.  Once the treasury has figured out how to tax the energy supplied from charging points, external charging will stop being a cheap option.
Perhaps the idea of "standard" battery packs that can be changed rapidly at "re-energising" stations might catch on if the industry ever gets trusted enough to let us swap our existing battery for another part way through a journey in exchange for perfectly good money.  Unfortunately, the commercial world is populated by box tickers whose only concern is how to put ticks in boxes, not providing a service that will allow a box to be ticked.  The powers that be at the top have never known the difference, and, as long as they get their obscene rewards for ticking boxes and a big golden handshake when caught out, they will never see the need.

You're a bit out of date.

Look at Flow-Cell batteries - works the same as a fuel-cell but you just need 2 tanks of electrolytes that can be drained & refilled in a couple of minutes. The drained electrolytes can be revesed back using locally generated electricity (solar or wind) and then re-used again.

Yes, it's a real can of worms isn't it but the owners will have acted in good faith when buying the cars so I think the manufacturers will have to take the hit. Could take years to resolve though, especially if other manufacturers have been doing the same. It almost defies belief that those responsible at VW thought they could get away with it.

Not that much out of date - flow cells are OK for large static applications, but are very much at the early development stage for automobile use.  Reversing the electrolytes is the equivalent of recharging, times will certainly be long as effectively energy is being transferred.  The electrolytes can be renewed by replacement, probably quite rapidly, but like any alternative fuel, infrastructure is needed to provide enough places where this can happen during a journey.

Maybe having the sniffer pipe rammed up the exhaust

        having the front and back wheels doing different speeds, on the brake test
         
            having the engine running with the bonnet open

If the figures are false for the emission how come the cars are passing the MOT, or is that flawed too?

I see what you mean, I think you are right in surmising that the tests are different but it will be interesting to see how this pans out. I don't think that MOT tests are standardised across countries in the same way as the original manufacturer emission tests. In the UK MOTs the emissions are not checked under load as far as I am aware. No doubt someone can enlighten us further.

Post by: Mad Scientist on September 30, 2015, 10:01:21 pm
According to someone who is a U.S. auto industry expert (and shall not be named here), it is alleged  :police: that VW used an engine control system to determine if the engine was bring tested, and, if so, started a special program designed to make the engine emissions-compliant. Then, after the testing, the program would return to the 'usual' settings.

So, an engine destined for the U.S. market engine would test 'clean', but would revert to a higher-mileage (and less 'clean' setting) when not being tested. <*<

Given that it's a software issue, it's possible that VW used different programs for different types of testing in various jurisdictions.

Post by: tigertiger on October 01, 2015, 02:40:51 am
Probably the best explanation of how they did it.


Archer, the former managing director of the UK’s Low Carbon Vehicle Partnership and non-executive director for the government’s Renewable Fuels Agency, said the scandal could spread into petrol cars and CO2 levels. “It is probably not limited to diesel and not limited to emissions,” he added.
The devices are thought to work by injecting more urea – an exhaust fluid – into the car when it is being tested. This limits nitrogen oxide emissions. The car detects it is being tested because devices such as the anti-collision systems have to be turned off when it is in the laboratory. The extra urea is not injected into the car when it is on the road because it would quickly run out.
Archer claims European tests are more open to abuse because they are conducted before the car goes into mass production and by companies that have been paid by the carmakers. These testing companies have been verified by regulators in each country, such as the Vehicle Certification Agency, but in the US the tests are conducted by an independent body.

Post by: Umi_Ryuzuki on October 01, 2015, 07:16:44 am
In the US, the testing stations don't typically use the sensor in the tailpipe method anymore.
When you pull into the testing station, a technician plugs a computer interface cable
into a socket under the dash. Like your computer sensing a USB, or Thumb drive, the car
probably senses that an interface cable has been connected, and reacts to that connection,
and goes into testing mode by lowering the fuel air mixture ratios to burn cleaner.
Or inject the DEF fluid into the exhaust.

I kind of wonder how often people have to refill their DEF reservoirs...

As the main constituent is apparently Urea it may be possible to refine your own... %)

However I am now even more confused. My understanding is that the fluid is intended to combine with the NOX emitted to make it safe. A DPF is what it's name says, a filter for particulates which are composed of soot from unburnt fuel and not a gas as is NOX.

Many cars don't have the fluid tank. For example the Mazda 3 does but the Mazda 6 doesn't. Can anyone actually explain the relevant processes as opposed to guessing?

Motorists themselves will not be liable as they bought their vehicles in good faith based on the assurances of the manufacturer. They may however suffer if the cars are remapped to reduce emissions with the result the power and MPG are reduced.

Yes, that does give a useful rundown but it doesn't mention NOX levels which seems to be causing the most concern. The fluid appears to be used to burn off the soot. The Mazda 6 and other cars inject fuel into the cylinder on the exhaust stroke as an alternative method of combustion. So what is it that reduces the NOX gas emission?

Also interesting to see that removal of your DPF could invalidate your insurance, I doubt if many people have considered that.

Sorry to hear that Mark, it must have been a real downer. DPFs on cars are expensive, especially if the turbo goes as well. Amazing that a truck costs that much though! I had a diesel Mazda 6 for three years two cars back and had no problems at all but when I came to replace it I concluded that diesels were simply becoming too complicated, too expensive to buy and too expensive to repair out of warranty so I bought a naturally aspirated (no turbo) petrol instead. Not an option if you need a truck though! My new 2 litre 6 is giving 45mpg which is not far short of diesel territory in general driving.

Far be it for me to defend any auto maker but after nearly sixty years in the auto industry I feel I can speak with some knowledge of what goes on in the business of maintaining & the repair of many different company's cars. One Japanese company I worked for had massive brake failures at low temperature( -20/-22c) This vehicle was never recalled.  The customer was mailed a voucher for two new wiper blades free, when he/she came into pick up the wiper blades we knew that that car had a defective brake Master cylinder & we asked the customer to wait for half an hour while we fixed a small problem, NEVER mentioning the brakes. Same company when they had to meet new emission standards their cars just would never run right when new from the factory. However the company in question sent us new jets & they fixed the problem. Of course the cars no longer met the emission standards, that is just the tip of the iceberg of what went on. In defence of the companies emissions were handed down by politicians most times with very short lead times who had no idea what it took to get cars to meet those standards. A case in point was MGBs, up to the middle of 1974 the engines produced 95HP @ the flywheel. At the end of 1974 that HP was reduced to 64 HP( North America,it was still O/K for the U/K to emit as before) at the flywheel to meet the American regulations. Can you imagine trying to sell a customer that wanted to trade in his earlier model built before the the end of 1974 owning  a post 1974 model. I can understand manufactures' trying to get around the standards short term until the engineers & scientists could catch up but I can't understand a company with a reputation like VW doing what they did. Years ago Ford with their Pintos & Bobcats had a fault that when hit from the rear the cars caught fire & because of the impact you could not open the doors & people burned to death. Top brass made a decision that accident claims would cost less than a recall (about $6.30 per car to fix) They estimated claims would not exceed more than $120 million dollars total, the first single claim was for $128 million. Then we had all the tire failures here in North America that killed dozens of people.No companies should be allowed to do their own monitoring, it has been proven time after time. Mick B.

can't understand why it would be illegal to remove the dpf, if the emmissions still fall withing the prescribed limits, how can it be illegal, the ecu changing the settings during test may not change it by much as the limits are quite far ranging depending upon the age/condition of the engine i.e. if looked after the difference between 'on test' and real world cannot be that much.and the dpf is to remove particulates, but not all cars have these systems unless they are german or their partners - yes?
as for a game changer for the industry and this brand suffering, nah, their government will fine them tell them to put out a software patch upload it for pennies and reduce the cost, people will still have the need to drive a car and any chance they get they will still want a german brand as most are richard craniums when driving as these are quick off the mark etc, top of the list is the BMW idiots and next is the audi a3 boy/girl racers etc etc etc (the views expressed here are not aimed at those BMW, VW incarnates that do drive responsibly  :} )

Also, if you have removed a piece of original equipment or it isn't working then the car will not pass its MOT and will thus become unroadworthy.

I think you will find that the reason that a car with DPF removed still passes the emissions test is because you have simply converted it into a pre DPF vehicle and there are still many of those on the road so the test has to be set at a level that will allow them to pass.

 %).....in OZ, our WV Group Australia have recalled or withdrawn from the sales offices all of the new diesel engined vehicles with the dodgy fuel computer

These vehicles will be the first group of vehicles to get the new computer system installed and then returned to the distributors to make them saleable

Current owners of said 'newish' offending vehicles will commence the recall for conversion under warranty in January/February 2016....yes 4 months away

Owners of vehicles outside of warranty are probably considering making an appointment with their Bank Manager >>:-( for an overdraft on their home loan to pay for the conversion...............although this all depends if enough owners get together with a Class Action against VGA  <*< & challenge their inaction in the High Court......

Now remembering, owners of VW vehicles in the USA that suffered faulty transmissions had their vehicles repaired under warranty as WV America admitted liability.....however WV Australia did not follow the same path for the same fault and our owners finally found themselves in the High Court O0 .....Derek
Title: Re: VW scandal

If it isn't compulsory, (which apparently in the UK it isn't), why would you want to have your car converted so that it uses more fuel and has a poorer performance? Earlier models of diesels without the latest emission gadgets will still remain legal to drive for the forseeable future despite their higher emission levels. I only ask because it is common practice to remove crudded up DPF filters at the moment which motorists are clearly happy to do if it avoids them having to fork out the eye watering costs of a replacement filter.

I previously had a Mondeo diesel without a DPF and found myself rather embarrassed by the cloud of soot that appeared in the rear view mirror whenever I put my foot down. My second diesel, a Mazda 6 with the same size engine had a DPF and was around 5mpg worse in terms of fuel consumption demonstrating how these gadgets do strangle performance. My present car is a petrol Mazda 6 which returns just under 2mpg less than the previous diesel version in day to day driving.

It seems that the manufacturers simply cannot meet the current regs with the present generation of diesels, hence the VW cheats and no doubt others as well. In the meantime petrols seem to have been more amenable to improvements.

Well if VW diesel engines currently comply with UK and or Australian regulations, why are the vehicles being converted under warranty?...there is more than meets the eye here >>:-(

I suppose the second hand value of the vehicle may determine or sway any need to convert, and secondly any Government retrospectively applied regulations  <*< may also be a factor... Derek

Obviously VW will get hammered by the regulators but at this stage it is not at all clear to what extent VW owners have/or will suffer personal loss as a result of this fiasco.

It will take a long time for all the ramifications to become clear and these may well differ from country to country depending on their legal frameworks. I suspect that the EU will do their very best to try and sweep the whole thing under the carpet as much as possible due to the employment and economic effects of flattening VW. Politicians tend to be pragmatic in these situations especially here as nobody has (specifically) died!

The pickups are REALLY cheap to buy and their spec is huge too - leather, 6-seater crew-cab, 4x4 air con - electric everything.

A couple of years ago, there was a GM stand at the end of the Test Track ride at EPCOT - the truck there was huge - V8, massive wheels, massive crew-cab (3 seats across, huge bed on the back - about 20' long in total - $18,000.

I'd buy it!  :-))

Their 'gas-guzzlers' don't guzzle - I had a 4.6 litre Lincoln Town Car (limo) that averaged 30mpg (US gallon). The 305bhp Impala I had last year did 34mpg.

My 2.2 GM Eurobox only does 28mpg (UK)

No, I don't live in town. My driving is a mix of twisty country B roads (lots of acceleration/deceleration), one mile shopping trips to the village and maybe 40 miles on a dual carriageway with a 50/60 mph limit once a week - so quite a mixture really. Car is the new Mazda 6 with a very high compression ratio, normal aspiration with no turbo 165ps. Normally carries two up plus a heavy spare wheel.

I dare say it's using direct injection, which allows very high compression ratios through the use of stratified charge, preventing detonation. All the same these engines have to resort to using a more conventional air fuel ratio when power is called upon e.g. pulling away.

I find economy halves on my car when driven on short journeys compared with longer runs, the only real solution is lighter smaller cars. All the engine technology in the world can only ring a few more percent from otto cycle. The inescapable truth is that most of the energy gets shoved straight out of the exhaust pipe.
