I was wondering what everyone's top speed has been in their LS and the conditions in which they did it. Last saturday coming home around 1am on the highway a sports car, the Infiniti version of the 300z?, was haulin ass. The highway was a three lane road, about 4-5 cars on the entire road, i was in the far left lane, the other guy was in the middle lane. About a half mile ahead was a car going kinda slow in the middle lane so the Infiniti started to accelerate so i thought this could be fun. We both gunned it and i got a better jump because he wasnt going to beat me so he had to move over to the right lane to pass the guy in the middle. The LS slightly pulled on him all the way up to 125 mph in which i backed down and he passed me at about 120 mph. The look on the guys face was priceless, like i cant believe a 4 door just ran me. I didnt really care who won or whatever but i have got to say that the LS is the smoooothest car i have ever driven in excess of 100 mph before. At 125 mph it felt like it could have had more left and the ride was as if i was going 65 mph, and i had the sunroof open. In retrospect it was dumb, potentially dangerous, highly illegal and its not something i do on a regular basis. I think i have been over 90 mph about 3-4 times in the new LS. Its nice to see how your car will handle in certain situations and i was extremely pleased by the LS.
