I was curious as to how fast our cars are going when they hit the 60ft mark. So far, I haven't been able to find a lot of comparative data on it.

I did find a comparison of 60ft/mph times for a GTI-R shootout, and used them to come up with a prediction model.

See how these times and speeds compare with your own experiences:
