Have Yourself a Merry Little Swedish Supercar Christmas

The folks at Sweden's supercar builder, Koenigsegg want to wish you and yours (your plebeian sedan, of course) a Merry Christmas and a Happy New Year of Going Really, Really Fast. (We added that last part.) Were just wondering how they got the Ghost of Supercars Past to materialize for the shot. Swedes are really good at trick photography.
