The Surf, like the Karma, is driven by two electric motors, one on each rear wheel, and a lithium ion battery pack that gives it a range of 50 miles. When the battery is near depletion, an onboard turbocharged four-cylinder engine kicks in, generating electricity to power the motors for another 250 miles. Although Fisker boasts an astounding 981 pound-feet of torque for the power train, acceleration to 60 mph takes 6.3 seconds, well short of supercar territory.
