On this episode of HOT ROD Unlimited, follow along with Scott Shanks and his '70 Dodge Challenger convertible as he participates in the Royal Purple Performance Driving Experience at the 2012 HOT ROD Power Tour. For 2012, 5,000 cars were involved in a trek through seven cities in seven days, starting in Detroit and ending in Arlington, Texas. There's a big party every night, and the Royal Purple Performance Driving Experience is part of that scene. It encompasses three action events that are open to all the cars: an autocross, a drag race, and a burnout contest. See if Scott's 6.1L Hemi-powered Challenger is up to the challenge.
