I believe you answered your own question.
Four big sticky tires pulling, electronic assists, and micro-second shift times. It's doing nothing but accelerating at the maximum possible rate, while the Cobra is still trying to find traction in 3rd. The difference in 60ft. times would be enlightening. In addition, after 80 mph or so the Porsche has a significant aerodynamic advantage.
