France investigating FCA (updated)

by David Zatz on

Reuters wrote that a French prosecutor is investigating FCA for “aggravated cheating” in diesel emissions tests, based on the difference between nitrogen oxide emissions in test cells and on the road. FCA has denied breaking the law.

The main issue is likely the loosely written European law, which allows extensive use of engine control overrides; it is unlikely that FCA programmed in an actual test detection system. The company may be found not guilty; GM’s Opel division was also found to have on-the-road emissions far higher than lab emissions, but Opel was cleared of wrongdoing by French authorities.

Last October, FCA announced that it would voluntarily upgrade its Euro 6b calibrations to cut emissions in real driving conditions; upgraded calibrations for most cars were applied at that time, and made available (free) to vehicle owners. The company also committed to converting all diesel engines to selective catalytic reduction (SCR) technology.
