Despite recent funding setbacks and recalls involving the Karma’s battery pack and software, Fisker is moving ahead with plans to show a production version of its Surf Concept at the 2012 Paris Auto Show.

Sales of the Surf shooting brake (or station wagon, if you prefer) are expected to begin in late 2012 or early 2013. In time for the 2013 Geneva Motor Show, the automaker expects to expand its range to include a retractable hardtop convertible model as well.

As GT Spirit explains, Fisker describes the Surf as a cross between a sports car and a station wagon. Its shooting brake body style was recently used by Ferrari on its all-wheel-drive Ferrari FF, so the idea of a four-seat sports car with cargo room should no longer be that foreign to car buffs.

Like the Karma, the Surf will employ a battery-electric drivetrain that’s supplemented by a 2.0-liter, turbocharged four-cylinder engine that acts as a generator. On fully charged batteries, the Surf is expected to have a range of nearly 50 miles, but on fully charged batteries and a full tank of gas will be capable of traveling some 300 miles.

Valmet, who builds Karma sedans for Fisker in its Finnish plant, will also handle assembly of the Surf. Valmet has the capacity to build some 15,000 vehicles for Fisker each year, of which 7,000 are expected to be Karma sedans. The Surf is projected to be a low-volume model, with production of approximately 3,500 units over its lifespan.
