German brand believes such bands could help buyers of different driving styles better understand emissions for each car

Mercedes-Benz is considering introducing fuel economy and emission bands that provide an even clearer indication of the real-world figures drivers will achieve according to different driving styles, according to company boss Dieter Zetsche.

Talking ahead of this evening’s A-Class reveal, Zetsche (pictured below) highlighted the benefits of the new emissions test cycles, Worldwide Harmonized Light Vehicles Test Procedure (WLTP) and Real Driving Emissions (RDE), which are being phased in this year, but admitted that there were internal talks within Mercedes as to whether more could be done to help car buyers find accurate information.

Volkswagen, BMW and Daimler diesel monkey tests: brands have 'blood on their hands'

“The new regulations significantly address the issues of the old ones,” said Zetsche. “Under the old system, the focus was on CO2 and the tolerances for other pollutants were high. WLTP enforces a much smaller window of tolerance and tests across a much wider and more realistic range.

“But we can still see that the range is not the entirety - it does not take things like driving style into account. As a result, internally we are looking into the possibility of offering bands, for instance, that do give more realistic information on how driving style will affect your economy and emissions.

Meanwhile, Zetsche refused to be drawn on the latest scandal involving diesel fume testing on monkeys, declining to comment on that or whether he blamed Volkswagen for the current pressure the car industry is under. “There is nothing I can say that can help,” he said.

The latest revelation is that 2014 emissions tests on a diesel VW Beetle Diesel revealed it was more harmful to the poor monkeys that were gassed by it than a 20 year old ford diesel pickup.

The relevance here is that Mercedes and BMW are now becoming implicated. 

This makes EURO6 compliance a mockery and the legislation around the toxin tax a nonsense. So considering this is such a big deal for many motorists, where’s Autocar on this? Not wanting to upset it’s sponors maybe? 

What ever this is a relevant ongoing debate.

more obscure ? Is Merc worried that it's cars will be given ratings it does not like. Who's figures appear in the showroom and what do the salespersons say to customers. Do you believe the manufacturer or the official test results ?

Given how manufacturers have behaved why should they be allowed to do their own thing again. A system that is applied to all equally, however imperfect should at least provide a level playing field.

I am beginning to think the German car industry is beyond fixing.

I think Autocar would do well to encourage discussion on this serious point by opening things up and using Discuss as a platform.
