he will probably take you from a roll because once both cars are going the same speed, cobalt has to put the power to only 2 wheels as opposed to 4... wrx has more drivetain loss because its awd, therefore, from a roll he should be able to slightly beat you, but only marginally. from a dig, you'll have 2-3 car lengths on him by the time you 60mph, if not more. by the time he catches up and overtakes you, it won't matter because the 1/4 mile is long done with.
