Expect the '05 5-speed to run 0-60 in about sub 5 seconds (4.8-4.9), mid to low 13's @ 104-105. According to MT, The '05 auto will pull on a '04 GT 5-speed. The auto in the '05 are supposed to be top notch, and shift just shy of the 6200rpm redline at full throttle. The auto can be compared to that of Mercedes Benz AMG products! But 4 and 5 gears in the '05 auto mustangs kills any real forward movement. Some 3.73 or 4.10 would be awesome on the auto or badd ass on the 5-speed model. Rear wheel hp in autos are 265-268 and 5-speeds 274-279. Well beyond the factory '04 5-speed of 230 at the wheels. I don't think people should underestimate the potential of these new '05. Steeda has already over 100 aftermarket parts for the '05's. All the major supercharger companies should have blowers for theses cars real soon, as well as the major mustang turbo companies. The '05 mustangs will be a strong contender for years to come, and will continue to hold the title in the ever so popular street racing wars.
