To celebrate the Ford Mustang turning 30 years old in 1994, a trio of SVT Cobra convertibles served as pace cars for the 78th Indianapolis 500 race on May 29, 1994. The three cars were modified by Jack Roush at his shop in Allen Park, Michigan, for heavy-duty pacing on race day. The pace cars were installed with heavy-duty four-speed automatic transmissions, 15-gallon racing fuel cells, heavier rear springs (to accommodate the weight of television camera equipment), a Halon fire-extinguisher system, a rollbar with 50,000-watt strobe lights built in, and special lights in the rear spoiler. Parnelli Jones, a seven-time Indy 500 competitor who won the 1963 race, drove the official pace car at the event.
