At the Chicago Auto Show last week, Fisker Automotive brought along the Karma Sunset with a new black exterior we hadn’t seen before. For the Geneva Motor Show that starts in a few weeks, the automaker is going in the other direction and will be showing off the "advanced aluminum space frame" that underpins the Karma and gives the plug-in hybrid car "new levels of rigidity and strength" for "world-class ride and handling characteristics." Here’s how Fisker describes the frames, which will be made by Valmet Automotive in Uusikaupunki, Finland, in a statement:

    Though it forms the foundation of a large sedan the Karma space frame’s rigidity is exceptional even when compared to today’s sports cars. By utilizing 5,000- and 6,000- series aluminum alloys and a unique extrusion-intensive architecture, the Fisker engineering team achieved the best balance between weight and size.

Maybe at the New York Auto Show in March we’ll get to see the Karma’s raw materials. Nah, only joking. There’s more information after the jump.
