In the face of tightening emissions legislation and limited sales of its diesel derivatives, Porsche has confirmed that oil burners won't be part of its future plans.

Porsche CEO Oliver Blume has stated that the firm's future plans for more efficient engine technology will be focused around full-EV and hybrid powertrains. This move comes in the face of increasingly strict emissions legislation and diesel sales that constituted just 12% of Porsche's bottom line in 2017.

"Porsche is not demonising diesel," said Blume. "It is, and will remain, an important propulsion technology. We as a sportscar manufacturer, however, for whom diesel has always played a secondary role, have come to the conclusion that we would like our future to be diesel-free."

With the release of the company's Taycan electric sportscar next year and a mandate to electrify every other new Porsche, either by adopting hybrid technology or a full-EV powertrain. This development won't impact negatively on present diesel Porsche owners who, according to Blume, will be looked after "with the professionalism they expect."
