But the writing has been on the wall for diesel engines at Porsche, and the arrival of the new Cayenne without a diesel option looked to set the future path, as did Porsche's reaction to the defeat device they found lurking in their VW diesels.
Porsche has reportedly ceased production of vehicles equipped with diesel engines.
Speculations around Porsche dropping diesel technology altogether arose after the company did not launch a diesel version of the third-generation model of its Cayenne SUV.
Remember when the diesel Cayenne was launched, back in 2009?
In an official statement, Porsche said that the Macan S Diesel, has been "taken out of the production programme" as buyer demand moves towards petrol and hybrid versions. Clearly, Porsche has enough reasons to ditch the diesel powered models.
The brand revealed that the diesel's removal was also linked to "another software update" that has been subject to an "ongoing consultation with the authorities". The new Panamera sedan and soon-to-be-launched Cayenne large SUV are not now offered with diesel power, which may make a return for full-sized models in the future. While not directly confirming it, this suggests that like with BMW and its F80 M3, Porsche has decided against re-engineering the Macan S Diesel to conform to the new Worldwide Harmonised Light Vehicles Test Procedure (WLTP) standards.
In 2017, Porsche sold around 97,000 Macan SUV around the world, but only a small part of that was attributed to the diesel models. As the country is rushing toward adopting BS-VI emission norm in April 2020, diesel cars are expected to see sales going down significantly as pricing of the diesel models will be much higher due to the stricter norm. Petrol versions accounted for 35 percent, while the Panamera 4 E-Hybrid accounted for 50 percent. It is believed that diesel models made up only 15% of all Porsche sales in 2017, with that number likely to keep falling if the manufacturer persisted with a diesel offering. Porsche does not develop or build diesel engines itself. Porsche halted investment in diesel past year, shifting much of its R&D focus to electrification.
