[2][3] While riding around town in the family car, Lazier quickly scribbled a recipe for a new soft drink on a small piece of paper which he handed to his son, Charles Jr.

Crush International was purchased by Procter & Gamble in 1980, which sold its soft drinks holdings to Cadbury Schweppes plc in 1989.

[5] His son Dale Earnhardt Jr. was also sponsored by Sun Drop in the late model series in 1993; they will reunite for the CARS Tour race at North Wilkesboro Speedway on August 31, 2022.

[6] The soft drink was a leading sponsor for racecar driver Ryan Hunter-Reay in the IndyCar Series for Andretti Autosport from 2011 to 2013.

[7] Keurig Dr Pepper distributed Sun Drop nationwide beginning in 2011, with a new campaign that features an updated web site, a Facebook page, and a promotional deal with MTV.

[5] The Sun Drop marketing plan is a component of Keurig Dr Pepper's efforts to expand its non-cola soda sales and is targeting drinkers of PepsiCo's Mountain Dew brand of soft drinks in the United States.

[5] Sun Drop's expansion occurred several months after Coca-Cola brought its high-caffeine citrus drink Mello Yello nationwide.
