Six Oscar Mayer Wienermobiles are going to be racing at the Motor Speedway for the very first time in "The Wienie 500." Here's what to know.

The Wienermobiles have been around since 1936 as a promotional vehicle for Oscar Mayer — not to be confused with Louis Meyer, the first three-time winner of the Indy 500. They travel around the country, logging about 20,000 miles annually, though none were probably as important to the hotdoggers on board as the 5 miles they drove on Friday.
