The only thing that I have seen to date are estimates and they indicate 0-60 times in the R/T of "under 6 seconds". My 2005 Mustang GT will do it in roughly 5.2 seconds. Unless the R/T can match or beat that time, I'm probably leaning more towards a 2010 Camaro SS with 6-spd manual and 420 ponies for roughly the same cost as a fully loaded R/T!
