I bought a 2013 Stasis S4 from someone on this forum and I just wanted to share my impressions of the speed. After my GTR I decided that I really didn't need to be the fastest anymore, but I still wanted something quick. I decided to get a S4 after I found out how easy they were to mod, so I found one all done up (tune, exhaust, suspension) and I was ready to roll. Anyways, after running around with a lot of other car buddies this weekend we've all come to the conclusion that this Audi is F-ing FAST! Here are some examples....Ferrari F430 is faster, but not by much. Nissan GTR is way faster....lol, but then again, it's faster than everything. Viper and Corvette ZO6 are definitely faster 60-120, but again, not by as much as we all thought. From a roll, it's way easier to get the S4 going. I bought the car because I wanted a manual, so I don't have the benefit of launch control (like i had in the GTR), but it doesn't really seem to matter. There is a lot of grip and not too much power that you have to worry about overwhelming the tires (like I did in the Viper). Porsche GT3 and the Audi are about even, although we know on the track it would be a different story. 2013 Mustang and S4 were even as well. Crazy considering how much more the Audi weighs. In the real world, there doesn't seem to be much difference in terms speed. Way to go Audi!
