Scoti gave you a great description, but forgot to mention the origin of the term. A few years back the car magazines decided enough is enough with the Pro Street look. It had escalated to a level that most cars were nothing more than thinly disguised race cars.
They decided to try to turn the trend to cars that were totally functional. The idea was to encourage people to build cars that could go fast, stop fast, and fly around a curve while riding in the comfort of a/c.
They would be reliable enough to jump in and drive across the country with ease. To promote this concept they decide to have an event that would entice people to build cars and make a road trip with them, and the Hot Rod "Power Tour" was born.
The Hot Rod Magazine editor coined the term "Pro Touring" from a combination of "Pro Street" and "Power Touring".....
