Now that I have driven my nephew's 2009 Ford Shelby GT500 this comparison is even more interesting to me. The inferior tests 0-200 km/h time for the 5.0 is still making the comparison unfair, but the lap times are the important thing. I think that the stronger supercharged engine of the GT500 makes up for a lot. The 5.0 driver will be making more shifts on most tracks due to shorter 3.73 rear gearing. Bigger tires on the Shelby are an advantage as well. The 2011 5.0 has more direct steering, lighter weight, and no heat soak issues. My personal verdict is that the GT500 will get a better first lap given equal driving skill. On a long endurance race (especially in hot weather), the balance shifts in favor of the 2011 GT. This is my opinion, my nephew might think otherwise. Since he now knows about this site, he very well might chime in. :)

My nephew in Texas owns a Mustang Shelby GT500 and I of course recently purchased the 2011 Mustang GT. I haven\'t driven his car, and he hasn\'t driven mine, but I suspect that mine is going to be faster on most road courses. As for this comparison, the Mustang 5.0 is hampered on the data by an incorrect 0-200 km/h time from an inferior test and an incorrectly listed curb weight. Despite these details the competition is close. My nephew is a pretty good driver, and my competition skills aren\'t as practiced as they used to be, so I wonder if he would be willing to go to a track and see who can get the best lap time? Might be interesting.
