The effects of Volkswagen’s dieselgate issue has been huge. It threw into light the question of whether diesel vehicles are really tested properly and have the right emission numbers. In recent months, Porsche has been carrying out extensive analyses on their diesel vehicles of emission class EU6. These are related to the retrofitting of diesel engines for vehicles of the Volkswagen Group announced in Berlin on 2 August 2017 as part of the so-called “diesel summit”.
For the Macan 3.0-liter V6 diesel, Porsche has been carrying out a voluntary service measure since autumn 2016, coordinated with the Federal Motor Transport Authority (KBA). This measure has already been carried out in Germany with more than 8,600 vehicles. This corresponds to a fulfilment rate of more than 93 percent.
In addition, Porsche will shortly introduce another software update for Macan 3.0-liter V6 diesel vehicles to the KBA. After approval, Porsche will offer the retrofitting of a total of around 52,500 vehicles in Europe (14,000 in Germany). The owners of the vehicles are contacted directly by their responsible Porsche partner. The workshop visit, which is free of charge for the customers, will take place as soon as possible after agreement and will take about one hour to complete.
For models of the type Cayenne 4.2-liter V8 diesel, which expired in 2017, are currently held votes with the KBA. This involves a total of around 7,000 vehicles in Europe.
For the new generations of the series Cayenne and Panamera currently, no vehicles are offered with diesel units. Diesel engines traditionally play a minor role at Porsche. Porsche does not develop and build diesel engines on its own but takes full responsibility towards its customers.
In future, Porsche focuses on a trio of further optimized gasoline engines, plug-in hybrids and purely battery-powered vehicles.
