is it possible for the is to win since its 6 speed auto compared to the 4speed the lancer got
also remmeber there both stock and if they were both hooked up who would win?

The Mitsubishi is a Rally Car, while the Lexus is a luxury car. So I would tend to think that Mitsubishi wins. But at the end of the day, racing is only a small part of your life.
If it was for me, I would stick to the Lexus since I get all the luxury I want with very respecable performance.
