Porsche has announced the end of production of all diesel vehicles from its line up ahead up of the upcoming emission standards and due to a shift in consumer demand. Citing 'cultural shift' of the customers, Porsche has stopped production of the last two diesels in its lineup - the Macan S Diesel and Panamera 4S Diesel. It had only been nine years since the German brand's first diesel vehicle was rolled out in the market. The beginning of axing of Porsche diesel engines can be traced back to the company not launching the new version of the Cayenne SUV in diesel variant. Porsche Cayenne was the first Porsche to be offered with a diesel engine in 2009.
Porsche has said in an official statement that the Macan S Diesel has been "taken out of production programme" as customer demands shift to petrol and hybrids. The company went on to cite “another software update” that has been subject to an “ongoing consultation with the authorities” as a reason of axing diesel engines.
While there is no official confirmation, Porsche seems to be opting against re-engineering the Macan S Diesel to conform to the new Worldwide Harmonised Light Vehicles Test Procedure (WLTP) standards.
Stopping production of Macan S Diesel underlines the model's shrinking sales, which a Porsche UK spokesman said represented a small portion of the SUV’s 97,000 global sales from 2017. The Macan is also due to be facelifted in April.
A source at Porsche has also told Autocar UK that stopping production of diesel-powered cars in its line up does not "mean Porsche has decided to stop all diesel models" forever. But Porsche boss Oliver Blume revealed to Autocar last year that “diesel is not so important for Porsche”, adding that diesel sales made up just 15% of Porsche’s total worldwide sales, mostly in Europe.
Porsche has never developed its own diesel engines, unlike its petrol units, and has instead sourced them from brands within the Volkswagen Group. The German marque also stopped investment in diesel last year, moving its focus to electrification.
In May 2017, Volvo announced that it would not develop new diesel engine anymore. Volvo Chief Executive Hakan Samuelsson cited the increasing cost of reducing emissions of nitrogen oxide for diesel engines as a reason behind the move.
The existing Volvo diesel engines, introduced on vehicles in 2013, will remain in production. However, the current generation engines will not be in production after 2023.
