From Motortrend.comSignificant engine tuning on the 99 4.6-liter modular V-8 has lessened our all bark no bite criticism of Mustangs since 94. At the dragstrip the 99 GTs performance numbers though great for a Mustang are still not tops in this muscular crowd. Yet 0-60 mph in 5.4 seconds and a 14.0-second/100.2-mph quarter-mile run is as good or better than any stock Mustang weve ever tested Cobra or not. Slalom and skidpad figures closed in on those of the more sophisticated (and expensive!) Cobra at 66.8 mph and 0.86 g respectively with the independent rear suspended Cobra turning in 67.8 mph and 0.88 g. Viewed in this way the SVT superpony seems hardly worth the extra $7000.
