Well, it seems like that sex-on-wheels advert has done its job. Fisker's development of the oh so desirable Karma PHEV and its lower-cost sibling, now known as Project Nina (inspired by Christopher Columbus' escape from the Old World, no less), has been given a significant boost by the US government. Henrik Fisker himself has been quoted as saying that once the conditional loan is in, "it wouldn't take long to get the lower-cost plug-in hybrid on the road." If the company carries over the aggressive styling from the luxury model, it might have a real winner on its hands, though -- we know -- it's got to be cheap enough first. While waiting for that $528.7 million to work its magic, you can gawk at the solar paneled roof on the Karma, to be found after the break.
