Using SAE calculations to determine the "greenness" of their new sedan, Fisker found the Karma will consume just 3.5L/100km (67.2 mpg) while emitting 83 grams of CO2/km.

Fisker has announced estimated fuel efficiency and emission ratings for the Karma plug-in hybrid.

Using SAE (Society of Automotive Engineers) calculations to determine the "greenness" of their new sedan, Fisker found the Karma will consume just 3.5L/100km (67.2 mpg) while emitting 83 grams of CO2/km. This effectively means the Karma will cost as little as €0.02/km ($0.03/mile) when it's running on electricity alone. When the gasoline engine kicks on, the costs increases to €0.05/km ($0.07/mile).

Fisker also highlighted the fact that, "941 million liters (248 million gallons) of gasoline could be saved and 2.3 million metric tons (2.5 million US tons) of CO2 offset from sales of 15,000 Karmas per year through 2016."

As you may recall, the Karma uses two electric motors that produce up to 375 kW (403 hp) and 1,300 Nm (959 lb/ft) of torque. Power comes from a 200kW lithium-ion battery pack, which is recharged by a GM-sourced four-cylinder engine with 260 hp. When the battery is fully charged, the car can travel up to 50 miles (80.5 km) before the petrol engine kicks in to recharge it. This unique powertrain allows the Karma to accelerate from 0-60 mph in less than six seconds, before hitting a top speed of 125 mph (201 km/h).
