While the German carmaker has made no noises about it, we can look forward to seeing the 2015 S600 at the Detroit Motor Show next week. This would have been a pleasant surprise had one of Mercedes' media partners not blabbed about it. Pictures have yet to be revealed, so we await these with eager anticipation, but some info has been forthcoming. Power will come by a twin-turbo V12 rated at around 530 hp, and the S600 will be available exclusively as a long-wheelbase model.
