Selected diesel-powered Mercedes-Benz Vitos, Porsche Macans and Cayennes have been banned by Swiss government officials for having falsified emissions figures.

As reported by Automotive News, the affected vehicles are Mercedes-Benz Vitos that uses the 1.6-litre diesel engine, Porsche's 3.0-litre V6 diesel Macans, and Cayennes with 4.2-litre diesel engines.

These cars will be banned starting from 17^th of August but owners who are already driving these cars can still continue to drive on Swiss roads as long as their owners can get them retrofitted with the countermeasures from their respective companies.

This might be one of the stronger examples of what government officials around the world could do as a result of the diesel emissions cheating experienced by the industry so far. It is likely other countries will follow soon in time to come.
