Achieved through a software update, the changes allow the Karma to fall into the sub-50g/km CO2 category as pure electric vehicles in The Netherlands. In turn, this means it becomes exempt from the country’s emissions-based tax for company car buyers, offering savings of €43,500 (£37,353) over  a five-year term.

The Karma uses a 2.0-litre GM-sourced petrol engine as a generator and to supplement the power of its electric motor. This nupgrade is designed to reduce ancillary electrical losses, and improves the electric range by 3km to 86km. It will only be offered on vehicles sold in The Netherlands, but can be retro-fitted to vehicles which are already on the road to reduce their tax liability and fuel consumption.

Koehler, Fisker CEO of Europe and Middle East, said: ‘Fisker applauds the Dutch government for taking the lead in helping to promote the purchase of cleaner running car.’
