Tested: Fiat Emissions Up to 2200% Over Legal Limit

An independent German environmental group called Deutsche Umwelthilfe recently decided to test the real-world emissions of the popular Fiat 500X SUV, too see how they matched up to the company’s own emissions claims. The result? Not only did the the 500X produce more emissions than Fiat-Chrysler claimed, it produced between 11 (eleven) and 22 (twenty-two) times the harmful emissions expected. (!)

For those you keeping score, that’s up to 2200% more harmful Fiat emissions than the copmany promised. That’s bad.


Fiat 500X Emissions 2200% Over Legal Limit


Following the much publicized and highly damaging VW emissions scandal that led to the brand all but abandoning diesel vehicle sales in the US, Deutsche Umwelthilfe (DUH) has begun testing other carmakers’ products to see how they stack up. The resulting tests have caught a few more cheaters, but few have racked up scores as high as the Fiat’s.

In terms of raw numbers, the DUH found that the Fiat emissions system tested produced 1777 mg of NOx per kilometer at its peak in the 500X. Considering the legal limit is 80 mg, it’s clear that Fiat-Chrysler might have a cheating problem.

“The extreme overruns of NOx emissions that have meanwhile been detected with an Opel Zafira, a Renault Espace, a Mercedes C class and now a Fiat SUV are technically not plausible and point towards defeat devices,” says Axel Friedrich, co-founder of the Washington-based International Council on Clean Transportation (ICCT) that commissioned the original investigation into Volkswagen’s deliberate diesel test-rigging.

Fiat-Chrysler has, according to the sources indicated, below, declined comment on DUH’s claims- although Fiat executives did say, on Feb 2nd, that its diesel vehicles do not carry defeat devices. The company, instead, claimed that, while emissions levels may vary depending on driving conditions, its cars’ control systems operate in the same way under the same conditions, whether in a laboratory or on the road.

If the DUH is right, I guess that means the otherwise likable Fiat 500X produces 22x the legal limit of nitrous emissions in the real world, too?

What do you guys think? Will Fiat be the next company to get caught out by independent emissions testing, or are the testers themselves getting a little over-zealous? Let us know what you think in the comments section below.
