Multiple factors determine top speeds including track conditions, weather, temperature, the size of the race track, banking, the experience purchased and individual driving ability. As stated, “top speeds may reach up to” means exactly that. Top speeds are approximate top speeds. We take the average lap speeds and add to that speed to get an approximate top speed at end of straightaways. The higher programs we offer, the speeds will be closer to the actual top speed. Because it is an estimated top speed based off the average lap speed, the 5min & 8-16min programs will be skewed to the high side and the 24-48min programs will be closer to accurate top speeds, which will be reached at the end of the straightaway. Top speed will be printed for all drivers on your graduate certificate. All speeds stated are TOP MPH reached at the end of the straightaway, not the average lap speed.
