Maybe someone can check this with GPS...
In my opinion it is impossible to reach "real" 200MPH with a SRT-6. In KM/H this means 321,67!! I don't know the correct air-drag-coefficient (0,37?) x cross-sectional area (the right word for German "Stirnfläche"?) but I estimate, you need at least 500HP at the crank, if not more, to reach "real" 200 MPH. You can compare with other high-speed cars...Nevertheless the SRT-6 is a great car and very fast
