that will’s clear there needs to be big change within the coming weeks in addition to months in light of the Volkswagen emissions scandal that will has dominated headlines in recent days, however what form that will change will come in is usually not yet clear. These are the crucial questions that will will be discussed in addition to addressed as the matter unfolds.

So why did VW cheat the system?

For commercial reasons is usually the best analysis available at This kind of point, according to expert sources. Complying fully with the EPA test might have reduced the performance in addition to economy of the Golf, Jetta in addition to Beetle. VW’s types within the US compete within the cut-throat volume market where Great fuel economy in addition to performance is usually vital. various other German rivals that will sell diesel cars operate in a more expensive segment where mpg economy figures are not such a barrier to sales.

Can VW’s 2.0 TDI pass the US test?

Experts say yes. The EA189 engine uses a lean NOx trap (LNT) to store oxides of nitrogen, which are then burnt off in a purge cycle. This kind of technology is usually widely used in addition to works. BMW, for example, one of whose diesel types was singled out as fully compliant in real-world tests within the EU, use an LNT.

Will VW retro-fit cars be affected?

We don’t yet know. However, the cost of recalling types in addition to re-programming them will cost hundreds of millions of dollars. The big question is usually whether This kind of cost is usually worth bearing if, as seems likely, US consumers turn their backs on VW diesels.

So what cars will VW sell within the US?

within the short term, that will will have to move to a petrol-only line-up, in addition to rip up its entire diesel-based sales strategy. Another option is usually to rush plug-in hybrid powertrains, which VW badges as GTE, into production in VW’s two main North American plants, in Mexico in addition to Tennessee. However, establishing a supply chain will take at least 18-24 months, according to Cardiff University Business School professor Peter Wells. The technology is usually still expensive, so VW’s sales will likely suffer. Another option is usually to build Audis, however their volumes are modest in comparison.

What does This kind of mean for diesels in Europe?

The importance of diesel — that will was 53% of the EU market last year compared with 3% within the US — suggests lurid ‘death of diesel’ headlines are simplistic, at best. However, diesel is usually definitely under political pressure in addition to the industry needs to emphasise its strong points much more firmly. Car buyers know their advantages in addition to many will continue to buy diesels.

Are diesels complying with the latest EU6 rules?

As far as we know at This kind of point, there is usually no evidence that will EU car makers have ‘defeat codes’ to pass EU6. However, that will is usually true that will manufacturers have perfected multiple techniques to squeeze the last g/km out of the test, so a tightening of those rules seems wise. The test run by the EPA within the US is usually much more prescriptive in addition to more difficult to influence by clever test techniques.

What about petrol?

So far there is usually no proof that will ‘defeat codes’ have been used to boost MPG figures within the petrol EU6 test. The various investigations at This kind of point underway must clear up This kind of point.

What about problems with NO2 in city centres?

In real-world conditions, many EU6 diesels are not delivering the same mpg in addition to NO2 figures recorded within the test. The test was never intended with This kind of purpose, however that will’s what we’ve got at This kind of point. There is usually no requirement for in-use testing, except the UK MoT test, for example, which is usually only intended to weed out worn-out ‘gross polluters’. The EPA does in-service testing, which probably should be built into the EU test. however ironically, there is usually no US-wide test for cars in-use. that will is usually a state-by-state policy in addition to many, Michigan for example, don’t test.

A brand-new test is usually coming to clear This kind of up?

Yes – the WLTP — however Autocar understands that will that will will hardly tighten the regime in addition to is usually unlikely to have much effect on MPG/CO2/NOx numbers. The international aspect of the VW scandal should speed-up the decisions still to be made about the detail of the test in addition to its introduction date, possibly as far away as 2020. the vehicle industry may well be wise to re-think its strategy, within the light of the scandal, to ensure the brand-new test is usually robust in real-world driving. Otherwise, political pressure will only continue to cloud the future of diesel.
