The Unocal 76 Challenge was an award program for the NASCAR Winston Cup Series from 1989-1999 sponsored by the Unocal Corporation. Unocal posted a $7,600 cash prize if the pole position winner for each NASCAR Winston Cup event went on to win the race. If the prize was not claimed, it was rolled over to the next race until the pot was claimed. The award program proved to be popular among competitors and fans, and was considered NASCAR's version of a Skins Game. The award provided over $2 million in cash prizes to NASCAR drivers.
