BMW: “We don’t cheat”; diesel is needed to hit CO2 targets; call for WLTP and RDE

As the Volkswagen emission testing scandal threatens to spill over onto other automakers, BMW yesterday issued a sharp statement in response to a report in Auto Bild suggesting emissions from an X3 test were out of the norm.

The BMW Group does not manipulate or rig any emissions tests. We observe the legal requirements in each country and fulfill all local testing requirements. In other words, our exhaust treatment systems are active whether rolling on the test bench or driving on the road. Clear, binding specifications and processes are in place through all phases of development at the BMW Group in order to avoid wrongdoing.”

BMW noted that in two studies carried out by the ICCT, results confirmed that the BMW X5 and 13 other BMW vehicles tested comply with the legal requirements concerning NOx emissions. No discrepancies were found in the X5 between laboratory-test and field-test NOx emissions.

BMW said it was not familiar with test results that would suggest otherwise. The company said it was contacting the ICCT and asking for clarification of the test referenced by the press report. BMW further said that it would discuss testing procedures with the relevant authorities and make its vehicles available for testing at any time.

BMW also took the opportunity to speak strongly in support of diesel in the context of the coming 2020 emission targets in Europe.

Policymakers worldwide, and in particular in the European Union, are setting tough standards for CO2 and other emissions. The 2020 targets in Europe can only be fulfilled through extensive use of modern diesel engines and further electrification. The progress achieved so far in CO2 reduction in Europe is largely due to the use of diesel technology. Meeting future requirements will not be feasible without diesel drive trains, since a diesel engine emits roughly 15 to 20% less CO2 on average than a comparable petrol engine.

At the BMW Group, we have invested a great deal in recent years in refining and optimizing diesel technology as part of our EfficientDynamics program. At BMW, diesel vehicles accounted for 38% of vehicles sold worldwide last year: Europe 80%; Germany 73%; US 6%. This represents approx. 20,000 vehicles in the US in 2014.

The Euro 6 emissions standard, which took effect on 1 September 2015 and is binding for all new vehicle registrations, improves both environmental and consumer protection. To bridge the gap between test results and real-life fuel consumption and emissions, the European Union is working on a new test cycle (WLTP) and an emissions test for real driving situations, known as “real driving emissions” or RDE. We support the swift introduction of the new regulations to create clarity for consumers and the industry as quickly as possible.



I like that.
It certainly sounds like the response of a wronged woman, or more likely, wronged man!
It would be good to think that not all automakers are on the fiddle.

But as for VW and whoever from the present Hole in the Exhaust gang they appoint to act shocked about what has gone on:

'Nissan Motor Co (7201.T) CEO Carlos Ghosn said it would be difficult for an automaker to conceal internally an effort to falsify vehicle emissions data, such as has happened at Volkswagen AG (VOWG_p.DE).

The revelation at VW raises new “trust” issues for global automakers in the eyes of consumers, Ghosn told Reuters journalists in New York on Tuesday.

He declined to comment specifically on what happened within VW but said that a lot of people likely would know about such an effort within a company.

“I don’t think you can do something like this hiding in the bushes,” said Ghosn, who is also CEO of Nissan’s alliance partner, Renault SA (RENA.PA), as well as chairman of their Russian partner, AvtoVAZ(AVAZ.MM).'

This link has the story in English how the German magazine Build has found that BMW's X3 diesel emit 11 times the legal emissions.

If that is true we may have another auto scandal in the making. BMW shares are down 10%.

It is BS that we need dirty diesels to meet the new CO2 requirements. The same can be accomplished with either PHEVs, HEVs, BEVs or natural gas. Plenty of alternatives. It is hilarious that BMW is even trying to argue that dirty diesels are needed for consumer vehicles. They should be banned ASAP in the consumer segment. In the commercial segment they should be given 10 years before a complete ban is effective for new vehicles. The replacement fuel here would be natural gas.


Just in more good news about previously undiscovered health benefits of diesels:

'Atmospheric levels of a little known by-product from diesel engines are up 70 times higher than expected according to a study.

Researchers found that long-chain hydrocarbons are significantly under-reported in car manufacturer's data.

These hydrocarbons are a key component of two of the worst air pollutants, ozone and particulate matter.

The authors believe these "hidden" emissions are having a large impact on air quality in cities like London.

The tailpipes of diesel fuelled trucks and cars produce an array of emissions that have different impacts on the air that people breathe.

The nitrogen dioxide and particles that are emitted from burning diesel have a direct impact on human health in cities.

But diesel also contains more complex, long-chain hydrocarbons, who's role in air pollution has been little understood until now.

They can form dangerous air pollutants, especially ozone and particulate matter, which are emitted into the air as unburned fuel or diesel vapour.

Researchers from the University of York have been able to detect these complicated compounds in the London air, using sophisticated measuring technology.

"It's definitely been hidden until now," lead author Dr Jacqueline Hamilton told BBC News.

"What we found is that there's actually a lot of this unburned material from diesel that we haven't seen before."

"That might be having a bigger impact on ozone and particle formation than petrol cars are, and historically no one has looked at these emissions at all."

The researchers found that close to 50% of the ozone production potential in London in winter was due to these diesel elements. In summertime, it was around 25%.

The authors believe that these hydrocarbons are having a direct effect on health.

"I think it is having a large impact on air quality in our cities, the number of deaths associated with particle pollution are much higher than those from nitrogen dioxide, this is a route to increase particle pollution so it could have a major impact on human health."'

It is starting to look as though diesels are not quite as health enhancing as had been thought.

Not so long as you like breathing, anyway.

Davemart. Loved reading your tabloid clips. Now its time for my morning dump.

Excellent posts, Davemart. Thank you.


Excellent summary of current and realistic diesel issues. VW has clearly made this an issue people are not going to ignore any longer and diesels are going to begin to shift out of the LDV market going forward.

Diesels will be a subject in EVERY discussion about the smog problems in european cities.


I don't like the media's attack on the industry... DPF and SCRs systems easily out perform any TWC gasoline car as far as harmful emissions are concerned(when both are working properly).

It is possible to game the testing both ways, its much easier to make a car fail than to pass. Snapping the throttle can make any car pollute more than intended. If I wanted to make a car fail, I'd start there then move to more elaborate things like adding resistance to the HP fuel rail sensor or shorting it a little(depending on the system). Diesels will go buck wild, up until they send a rod through the block if you mess with their fuel rail pressure sensors.

CO2 is a given for most energy that we consume... anything we can do to reduce HCs/Soot and NOx from exhaust is a good step in my book. I believe modern US (Law abiding) diesel manufacturers are doing that, and they are about as good as they are going to get without advanced electrification.

Again, I am not an advocate for diesel... personally I'd never likely own one but demonizing an industry as a whole bugs me a little.

Advanced batteries and fuels can't get here fast enough.

I wouldn't mind a comparably priced 250mile EV to replace my gasoline burning car. (I drive a lot, I am going to need a lot of on board storage).



TESLAs 1000 KM and 1200 Km high performance BEVs will come out in 2 or 3 years (so say Mr. Musk). Shorter range (500 Km) Model 3 will be out by end of 2017 or early 2018.

Many other manufacturers will also market lower cost extended range BEVs by 2018 or so.

It is just a matter of time before alternatives to polluting gassers become affordable.
