Wow, the manual Mustang V6 manages 0-60 times in the low 5s, the auto Mustang V6 is a whole second slower (manual=5.2, auto=6.2) ! The Camaro V6 auto and Camaro V6 manual times are more or less the same, with maybe a few tenths in favor of the manual. The Camaro tested was also a Hertz rental V6 with 11k miles.
