Update 2/22: This story originally reported that Porsche was doing away with diesel entirely. Porsche Cars of Great Britian has since released a clarifying statement saying that it will launch a new diesel-powered Cayenne. This post has been updated accordingly.
Porsche entered new territory in 2009 when it launched the Cayenne Diesel, its first-ever oil-burner. Now, the diesel experiment seems to winding down. that Porsche has ceased production of the Macan S Diesel and the Panamera 4S Diesel, the automaker's only remaining diesel offerings. Speaking to the UK publication, a Porsche spokesperson said that this decision reflects the "cultural shift" away from diesels towards hybrid and electric vehicles.
Per Car and Driver, a Porsche spokesperson later clarified that the company will sell a new Cayenne Diesel, though its release date is yet to be announced. Still, diesel seems to have an expiration date at Porsche. The Cayenne Diesel won't come to the US, for example, and the company recently announced that it's doubling its investment in developing hybrid and electric cars.
Interestingly, Porsche recently launched a new twin-turbo V8 diesel just for the Panamera 4S, shown above. That engine will live on in the non-US-market Audi SQ7 and Bentley Bentayga Diesel, but not in the Panamera.
To US customers, this news likely isn't a big deal. The only diesel-powered Porsche sold here was the Cayenne Diesel, introduced for the 2013 model year and discontinued in 2016 when it was revealed that its VW-designed 3.0-liter V6 used emissions-cheating software.
So, if you want a fuel-efficient Porsche now, it'll have to be a plug-in hybrid. Or you can wait for the all-electric Mission E, which should be on the road some time in 2020.
