Porsche has reportedly ended production of every one of its diesel models, citing dwindling demand and an increased focus on petrol power and electrification.

According to Auto Express, the German brand has stopped producing diesel versions of its Panamera and Macan, after earlier opting not to introduce oil-burning variants of its new Cayenne. Porsche first offered a diesel engine in its Cayenne back in 2009.

?Diesel engines traditionally play a subordinate role at Porsche. Porsche does not develop or build diesel engines itself. Currently, the demand for diesel models is falling, whereas interest in hybrid and petrol models is increasing significantly,? the automaker said in a statement.

Autocar, meanwhile, reported that Porsche added that its latest stance on diesel was also linked to ?another software update? (as part of the Dieselgate scandal, then) that had been subject to an ?ongoing consultation with the authorities?.

The British publication speculates that this suggests Porsche has decided not to re-engineer its Macan S Diesel to conform to the new Worldwide Harmonised Light Vehicles Test Procedure (WLTP) standards, following a path laid by BMW, which will reportedly prematurely end production of its F80-generation M3 for the same reason.
