Opel has released an official statement regarding the German and British investigations into the usage of cheat/defeat devices in Opel and Vauxhall vehicles to pass emissions testing. The bottom line: neither automaker uses them.
Both automakers were found to be clean in their emissions software, and both governments found zero evidence to suggest Opel and Vauxhall played a similar strategy to Volkswagen to rig emissions in the automaker’s favor. Volkswagen continues to feel the blowback from its faults, postings losses and likely devising a plan to buy back vehicles from cheated customers.
However, both reports from the German and British do find well-understood differences between lab test emissions, and real-world driving scenarios. Opel has also been transparent with this issue, and has adapted RDE testing standards early, a voluntary move. The automaker will also begin using Selective Catalytic Reduction (SCR) technology for new diesel vehicles this coming August to further keep emissions in check.
