Doug Wolfgang started his racing career in Darryl Dawley’s hand-me-down supermodified and finished as one of the greatest sprint car drivers of all time. Driving for Bob Trostle, he won the Knoxville (Iowa) Raceway championship in 1976 and 1977. In addition, he won 45 sprint car features in 1977, which was considered a national record at the time. He authored Knoxville Nationals victories in 1977 for Trostle; 1978 for Bill Smith; 1984 and 1985 for Bob Wiekert; and 1989 for Danny Peace. Driving for Wiekert in 1985, he won an astounding 55 feature races. In 1999, the National Sprint Car Hall of Fame published a poll of the 25 greatest sprint car drivers in history, and Wolfgang ranked fourth in that poll. He was inducted into the Nebraska Auto Racing Hall of Fame in 2002.
