Volkswagen has revealed the names of the cars affected in the emissions’ rigging scandal, a week after the new broke.

As former Porsche boss Matthias Muller (pictured) was appointed chief executive of the Volkswagen Group, it said the models involved include the sixth generation Golf (2008-12), seventh generation Passat (2010-2014) and Tiguan (2007-15).

Also, this morning, Audi has said the 'defeat' devices were used in 2.1 million of its cars: the A1, A3, A4, A5, A6, TT, Q3 and Q5

The brand reiterated that new diesel vehicles with Euro 6 engines on sale across Europe now are not affected, including the current Golf, Touran and Passat.

A statement from the group supervisory board on Friday said they are working with lawyers in Germany and the US to investigate and clarify what manipulation occurred, and is beginning to suspend some employees across the group.

An update from the brand said five million of its cars with EA 189 diesel engines are affected worldwide.

A previous group statement detailed 11 million affected vehicles, with the remaining six million vehicles likely to be across other group brands including Audi, Skoda and Seat.

Muller succeeded Martin Winterkorn who resigned on Wednesday, taking responsibility for the “irregularities that have been found in diesel engines”.

German regulators have asked VW to come up with a plan by October 7 to show when its vehicles will meet emission requirements.
