off the line, and for at least a short distance, the mustang has a pretty good chance, simply because the WRX has to spool up its turbo for horsepower, and the mustang will have quite a bit more low torque.
Off the line(yes, we were on city streets, but I think we got up to all of 40mph) my thunderbird LX (205hp, weighs as much as an elephant) beat my friend's WRX.
For stop to low mph speed, a larger displacement engine will win.
