Robert Glenn Johnson Jr. , better known as Junior Johnson, was an American professional stock car racing driver, engineer, and team owner as well as an entrepreneur. He won 50 NASCAR races in his career before retiring in 1966. In the 1970s and 1980s, he became a NASCAR racing team owner, winning the NASCAR championship with Cale Yarborough and Darrell Waltrip. He is credited as the first to use the drafting technique in stock car racing. He was nicknamed "The Last American Hero," and his autobiography and movie based on his upbringing is of the same name. In May 2007, Johnson teamed with Piedmont Distillers of Madison, North Carolina, to introduce the company's second moonshine product, called "Midnight Moon Moonshine", a nod to the days of his early youth in the 1940s when he made a living as a moonshiner/moonrunner and bootlegger.

Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle.
