I don't know what it would feel like going over 100MPH in a prius.. probrably like a pea in the wind?.... I went 90mph on my test drive and I didn't even feel it!... I couldn't believe I was going so fast!..... I've read top speed of 110 another place 115... but there in utah... I guess they set a hybrid record speed of 130.794 miles per hour on a 3 mile course. http://hybridcars.about.com/od/news/a/priuslandspeed.htm **Who ever has tested.. please post your top speed... and what did it feel like going so fast in the Prius?
