The Surf can be expected in showrooms in the first half of 2013 with a price tag in the low six figures.
With an identical drive train to the Karma, the biggest thing the Fisker Surf offers over the Karma is its luggage space and aesthetics.
The car comes with two drive modes - Sport and Stealth.
In Sport mode, the massive 981 lb-ft (1,330 Nm) torque of the vehicle is on tap with 0-60 mph time of 5.9 seconds, and a top speed of 125 mph (201 km/h).
In Stealth mode the generator stays turned off, so the Surf has a limited range of 50 miles (80 km) dictated by the 20 kWh lithium-iron-phosphate battery pack carried inside the car's central tunnel. In this mode, it accelerates from 0-60 mph in 7.9 seconds with a top speed of 95 mph (153 km/h).
The drive train is a series-hybrid, with only the rear wheels driven by electrical energy, which can be topped up by the 260 bhp turbocharged and direct-fuel-injected gasoline engine generator.
Under normal driving conditions, battery power alone will drive the Surf about. After that the gasoline engine/generator and 9.5-gal (36 l) fuel tank provide another 250 miles of range for a total of 300 miles (483 km).
Using a standard 110-volt household supply, the Surf's battery will fully recharge in about 14 hours. The Fisker Surf can also utilize standard European 220-volt outlets, allowing this time to fall to about six hours.
