ok first of all these people above me have no clue what they are talking about look at the facts! 0-80 mustang will most likely win but 0-100 most likely the rsx because it has a better top speed. i would have to say it also depeneds highly on your driving skills it is only 1sec difference and it does not take much to **** that 1sec lead up geting off the line. good luck im routing for you i love mustangs.btw a mustang is better for launches because of the torque so if your going 50-100 race the rsx-s will win if both cars are stock, like i said before because it is for high end power while the mustang is low end. this is the reason why a mustang beats a rsx-s in the 1/4 mile.also from acurazine.com the tested 1/4mile for the 04 rsx type s is 15.1and from mustangforums.com the tested 1/4mile for the 97 mustang gt is 14.2so the mustang is about 1sec faster than the rsx.
