The 1989 Autoworks 500 was the 28th and penultimate stock car race of the 1989 NASCAR Winston Cup Series season, the 11th and final race of the 1989 NASCAR Winston West Series season, and the second iteration of the event. The race was held on Sunday, November 5, 1989, before an audience of 65,000 in Avondale, Arizona at Phoenix International Raceway, a 1-mile (1.6 km) permanent low-banked tri-oval race track. The race took the scheduled 312 laps to complete. Assisted by a late-race crash from the championship leader at the time, Rusty Wallace, Melling Racing driver Bill Elliott would manage to take over control for the final 48 laps of the race to take his 32nd career NASCAR Winston Cup Series victory and his third and final victory of the season. To fill out the top three, Junior Johnson & Associates driver Terry Labonte and Roush Racing driver Mark Martin would finish second and third, respectively.

Melling Racing was a Championship-winning NASCAR Winston Cup Series race team owned by Harry Melling and his son Mark Melling. Harry Melling ran the team from its inception in 1982, to mid-1999. When Harry died after a heart attack in mid-1999, his son Mark then took over Melling Racing until the team closed in 2003. The team was most notable for fielding cars for Bill Elliott in the 1980s, where he won the 1985 Southern 500 at Darlington to claim the first ever Winston Million bonus, claiming the fastest qualifying lap in NASCAR history at Talladega Superspeedway with a lap of 212.809 mph in 1987, and winning the 1988 Winston Cup championship. Melling won 34 career NASCAR Winston Cup races, all of them with Bill Elliott.
