I managed to run the car down a timed 0-60 strip at Trax 2002 show at Silverstone. The images below show the printout and compare the computer model with reality. Notice how the printout starts at 6mph. This was because they had trouble timing the start - vibration of the car could cause false readings. I'm not sure what to make of this. In the worst case it means that my 6-60 time is 7.3s in which case the 0-60 will be more like 7.7s or similar. However, the accelaration model gives realistic 1/4 mile times and speeds and it matches the test data quite well.
