Statement of the Adam Opel AG regarding allegations of the Deutsche Umwelthilfe

23 Oct 2015

Opel emphatically rebuts the claims of the German Environmental Relief. We would once again like to emphasize the following, valid for all our cars: GM developed software has no features that detect whether the vehicle is undergoing an exhaust emissions test.


The results of the alleged Zafira test conducted by the German Environmental Relief (DUH) are not comprehendible. It is not fair that the German Environmental Relief makes assertions but did not disclose the alleged results, despite us asking for them on multiple occasions.


After receiving the communication from the German Environmental Relief, our engineers immediately put a corresponding vehicle (a Zafira with a 1.6-liter Euro 6 diesel engine) on the test bench and conducted and protocolled additional tests in accordance with the regulations – both on a two-roller and a four-roller test bench. The result: the values comply with the legal limits both for testing on two-wheel or four-wheel setups. This is the only result to be expected, as it has no influence on the emission systems whether or not the rear wheels are in motion. This means: The allegations are clearly false and unfounded.


An approach, as implied by the German Environmental Relief, would contradict our integrity, our values and the work of our engineers. We are committed to the reliable compliance with exhaust emissions thresholds in all our vehicles. We have clear global processes that ensure that our products meet all exhaust emission standards in the markets they are sold in.
