Significant 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 GT's 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 we've 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.
