The prototype saloon, developed by American automaker Fisker Automotive, can travel 50 miles emission-free on a single charge of its Lithium-ion battery.
The Karma can travel an additional 250 miles on a range extending generator turned by an efficient four cylinder petrol engine.
Economy is 2.4L/100km and emissions of just 83g/km CO2 - better than today's best hybrids.
Still, the Karma can reach 62mph in about 6 seconds and exceed 125mph.
HRH Prince Frederik is due to arrive in the Fisker Karma at the Hopenhagen event at Raadhuspladsen around 4pm.
