I believe this is by far the best comparison I've seen to date. 2011 Mustang against the 2010 Mopar and GM. I still think that if you are going to compare performance then its best to use the cars that will compete head to head. SRT-8 to SS to GT. To finish second in a race of three is like kissing your sister but finishing third would be like??? The HP and torque from the 6.1 shows itself to be the more powerful of the 3. Just the weight is holding it back. Handling and braking is superior or equal to the SS. Now lets see what 2011 holds for the SRT-8 Challenger and SS. Hint 6.4!!!!
