Compliance isn't clean enough for Fiat Chrysler

To get ahead of any Dieselgate-related issues or legislation, FCA is taking a proactive step and attempting to make its already-compliant European diesels even cleaner.

In the US, FCA's diesel offerings are limited to its Ram pickups.

Automakers continue to fall under scrutiny in the wake of Volkswagen's Dieselgate brouhaha. Some, like Daimler, insist everything is up to snuff. Others, like Fiat Chrysler Automobiles (FCA), are attempting to get ahead of the curve.

While London-based FCA insists that its diesels are currently compliant in their respective markets, the company is taking it one step further. Starting in April 2016, the company said it would offer new engine calibrations for its European diesels that meet Euro 6 emissions requirements.

This isn't a recall, but rather a voluntary update to ensure future compliance with new tests. The EU parliament is set to vote this week on new rules for future diesels -- specifically, whether or not real-world emissions should be allowed to exceed lab-tested results, and by how much.

"FCA will continue working to improve its diesel vehicles' emission performance in line with its own goals for sustainability and to properly address public concerns over diesel technology and its application in vehicles," the company said in a statement.

In addition to the new Euro 6 calibrations, the company will ramp up its use of selective catalytic reduction (SCR) in diesels that don't currently use the technology. SCR injects a liquid (you may have heard it referred to as urea or AdBlue) through a catalyst and into the exhaust stream in order to convert nitrogen oxides before they're emitted into the atmosphere.
