FCA (Fiat Chrysler), as a voluntary measure, not mandated or requested by any regulatory authorities, will be updating its Euro 6 calibrations with new data sets to improve emission performance in real driving conditions. These new calibrations will be ready starting from April 2016 and will be available on all new vehicles sold on or after that date, and will be made available to all other owners of Euro 6 FCA vehicles at no charge, as part of vehicle calibration update programs that are implemented on a regular basis. This does not constitute a recall campaign, the company said.
In addition, FCA said it intends to accelerate its ongoing programs to expand application of Active Selective Catalytic Reduction (or SCR) technology that is already used in certain FCA vehicles, to make it available on other diesel engines families starting from the second quarter of 2017, well in advance of any applicable regulatory requirements.
The company said it 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.
Spurred by the Volkswagen emission cheating scandal, FCA conducted a thorough internal review and confirmed that its diesel engine applications comply with applicable emissions regulations.
In particular, the company emphasized that FCA diesel vehicles do not have a mechanism to either detect that they are undergoing a bench test in a laboratory or to activate a function to operate emission controls only under laboratory testing. In other words, although emission levels vary depending on driving conditions, the emission control systems of the FCA vehicles operate in the same way under the same conditions, whether the vehicle is in a laboratory or on the road, and FCA diesel vehicles when tested following the only testing cycle prescribed by European law (NEDC) perform within the regulatory limits and comply with the relevant regulatory requirements.
FCA acknowledged that public attention is shifting towards measuring emissions performances under conditions that more closely reflect real-world driving conditions, and is debating the choice of an alternative to NEDC.
Currently in Europe vehicles are being tested by a range of entities in a variety of member states using an assortment of procedures none of which are prescribed by law or share any commonality. The EU is working towards the adoption of a new testing procedure in order to bring it closer to what one would expect under real driving conditions. (Earlier post.) FCA said it supports these efforts and welcomes the introduction of new regulations which should provide clarity for customers and the industry.
