depends on the course.
The charger has a bigger engine, but weighs a lot more. The charger still has the better power-to-weight ratio, so it's faster in a straight line, and has a higher top speed.
but the lancer has a shorter wheel-base, and less weight to corner.
a course with long straights,a nd the charger wins hands down. a course with a lot of turns, and the lancer wins.
or are you talking endurance race? if you're racing NYC to L.A., the lancer probably gets significantly better gas mileage. I bet it has to stop less often, and wins that race too.
