Not sure just what the "factory" top speed is set at before the car shuts down but I have an automatic and decided to try to see at what speed it would shut down at. I was in 4th gear and it had just hit 5th @ 147 MPH. It was still climbing but I let off @ just over 154. That was fast enough for me, I love my life!!!
