Fiat-Chrysler group models given emissions all-clear

As the VW emissions scandal rolls on, the Fiat Chrysler Automobiles (FCA) group has stated that its cars do not use defeat devices, confirming that its vehicles are not able to differentiate between testing cycles and normal driving.

The software used in its diesel-powered vehicles has been checked by the company and found to be free from test-cheating defeat device software, to the extent that it is confident enough to declare that its fleet is fully compliant with the regulations. The group includes brands such as Fiat, Chrysler, Jeep, Alfa Romeo, Abarth and Maserati.

Despite this, FCA is upgrading the software fitted to cars manufactured from April 2016 onwards to improve emissions performance, while also offering the upgrade free of charge to owners of vehicles fitted with a Euro 6 engine too.

A FCA statement said: "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.

"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 acknowledges 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."

Going forward, FCA has also announced its intentions to expand the use of active selective catalytic reduction (SCR) technology to diesel models to improve emissions performance further across the model line-up.
