i own a 2011 mustang GT
i own a 2011 mustang GT california special. I have the 6spd auto. I can get 0 to 60 times of 4.7 to 4.9 sec if I shift it manually. its a little slower if it shift its self. I just rented a 2015 mustang GT with 6spd auto. I cant get it to 60 in under 5 sec. best time is 5.0 sec. with it in sport + mode . I just read a review i think by car and driver with the same setup hit 60 in 4.5 sec. Not sure how they did it. I wounder avis did somthing to it. by the way im running 91 oct in both
