Endurance testing is intended to exercise every aspect of a vehicle. SRT engineers select a track for its rough surface conditions. Test cars are beat, and the cars need to take every bit of it.

The 24-hour test is conducted over the course of four days. Each 12-hour day includes at least six hours of track time. The rest is downtime for pitting to install new tires and brakes.

It's grueling. If you run three hours per day as a driver during this test, you're whipped at the end of the day. By the end of the week, if you ran the entire four days, you are ready for a vacation.

After the test, SRT engineers will tear the car down, inspect parts, pull motors out and tear them down. In some cases, the cars will even be rebuilt and reused for other purposes.

The car only passes when it completes the test requiring just the replacement of wearable items to be replaced. Engines, axles, transmissions and suspension components must all be intact at the end of the week to be approved for production.
