The production version of the Porsche Mission E concept will debut in 2019.

Stuttgart - Porsche is planning to electrify its entire range by 2022, it announced on Monday, with over six billion euros (R90bn) set to be invested in developing hybrid and full electric cars over the coming five years.

Of the additional three billion euros being put on the table, some 500 million euros will go towards developing Porsche's flagship all-electric vehicle known as the Mission E, slated for release in late 2019.

Porsche says the Tesla-rivalling saloon will boast around 447kW and a range of 500 kilometres between charges.

Around one billion euros of the additional cash will go towards developing electric and hybrid versions of existing models, "several hundred million euros" will be spent on expansion of sites, and around 700 million euros in building up a network of fast charging stations for electric vehicles.

But Porsche is not turning its back on the traditional combustion engine completely, despite increasing suspicion of the technology in Europe since Volkswagen's 'dieselgate' emissions cheating scandal broke in 2015.

Its investments in electric cars are part of VW's group-wide drive to speed up introduction of battery-powered vehicles.

Porsche chief executive Oliver Blume told news agency DPA that, despite the increased costs of building electric vehicles, the luxury subsidiary would aim to uphold its operating margin of 15 percent over the long term.
