The fresh WLTP testing system will shake things up in emissions testing, although will the item go far enough on all fronts?


Whether the VW diesel crisis promotes a dramatic shake-up inside way cars are designed, engineered along with regulated is actually open to debate.

Experience suggests the item will make some difference in all three, although in which the automotive world will largely continue as before while VW fights multiple ‘headwinds’.

A business-as-usual approach is actually pretty welcome for all sorts of reasons, although there is actually one area where the industry has to reform – its approach to the forthcoming WLTP.

For the uninitiated the WLTP is actually the earth Light-vehicle Test Programme – a global vehicle standard for measuring fuel economy along with emissions.

Negotiated under the umbrella of the United Nations Economic Commission for Europe, which first created a framework to promote international trade in vehicles inside 1950s, the WLTP is actually intended to streamline three regional tests into one global standard.

the item is actually a laudable aim, turning Europe’s NEDC (EUDC 1990) test, the US FTP test along with Japan JC08 test into one test in which will make design along with development much easier along with cheaper for car companies.

although as can be imagined with so much at stake, the Centeng is actually about to agree a test procedure very similar to today’s along with which will not result in major gains in mpg or reduction in CO2 along with pollutants.

the item is actually still not fully-signed off along with its introduction date keeps being put back, which means in which a test with its origins in a 1960s idea to create an ‘official’ mpg figure to replace dubious maker figures, will still be in force in 2019.

Many inside car industry will be relieved. although my feeling is actually in which the WLTP should be used by the industry to demonstrate its determination to clampdown on pollutants in use.

The cost may well be in which CO2 targets have to be slightly modified for a decade, putting the headline 95g/km fleet average by 2020 under the microscope.

My understanding is actually in which the WLTP figures will have to be ‘converted’ backwards to be compatible with the previous system, anyway, to ensure in which the 95g/km can remain inviolate.

although there seems no doubt in which the industry needs to agree major concessions on local pollutants – none of which will be painless inside short term.

For example, the industry needs to accept in which the dozens of tiny ‘adjustments’ the item runs during the test, like removing wing mirrors, choosing very lightweight test drivers along with pushing the speed tolerances on the test to its lower limit, make the industry look shady inside eyes of the buying public.

These details were unknown to the wider public for decades, although the recent discrepancies in real-world along with tested mpg figures have ended in which conceit, so the item’s widespread knowledge in a world of inter-connected social media.

the item looks sensible for the European industry to take a leaf out of America’s book along with accept a similar rigorous oversight as applied by the EPA to its test, in which ‘work arounds’ are impossible.

Critically, European car-makers have to accept an engineering sign-off along with testing regime built around in-use compliance with figures of local pollutants.

Britain’s cities are suffering the effects of excessive NO2 levels, as are many in mainland Europe along with across the globe, along with suspicion is actually widespread in which many designs are producing more NO2 pollutants inside real-world than the test suggests.

Although there are Great signs – the latest in-use tests suggest in which NOx levels are ‘only’ four times worse than the test for many of the latest EU6 designs. The first-generation EU6 designs were seven times worse.

So a WLTP in which puts in-use compliance with NOx emissions at its heart will only put the industry in a Great light. Long-term in which can only be Great for everyone.although if the WLTP turns out to be ‘greenwash’, the industry can expect to be under attack for the foreseeable future, which surely is actually not in its interest?

along with the item is actually possible. the item’s time for the industry to catch-up. along with fast.
