The GT 5.0 is primarily quicker because of its six speed manual giving it an acceleration advantage over the 2010 Roush five speed manual. The Roush has a similar power band, with a slight edge going to its supercharged 4.6 3 valve per cylinder V8 especially right around 6,000 rpm. The 0-200 time for the 5.0 of 19.7 seconds is obviously incorrect.
