Maybe you all can help me with this?? I happened upon what appeared to be a stock S4 at a stoplight the other morning. I pulled up next to him and when the light turned green we both took of casually then he just takes off, by the time I realized what was going on he was about one car length ahead of me, I run out first get into second and run that all the way as soon as I shifted into 3 we were neck and neck, I run out third and I’m about half a car ahead, then we go into 4th and he just leaves me probably about 1 1/2 cars to 2 car lengths ?? I am sitting there trying to figure out what just happened?? We both shut down after he pulled on me, we get next to each other and he waves and I follow suit. Any idea what a car like that would have done to school me so badly?
