The cabin of a NASCAR race car can get very hot during the race. As a result, the drivers sweat quite excessively. Just how much liquid can a NASCAR driver lose during a race?

To qualify to be a NASCAR driver, one must not only have excellent driving skills — but also physical endurance. The heat inside the cabin alone can cause the driver to lose between 3 and 4 pounds of water.
