It was hoped that the Mirada would reopen the door to Dodge success in NASCAR racing, as the nameplate had not won a race since November 1977. Lee Iacocca personally called Richard Petty, a longtime Dodge driver, in late October 1980 and asked him to build and test a race spec Mirada, saying Chrysler would supply Petty Enterprises the necessary body sheetmetal and engine parts Petty would need to build and campaign the car. Petty, who had left Dodge for General Motors in 1978, agreed, and had his team immediately set about and built a Mirada-based race-car. A few other teams including Junior Johnson's team built race-spec Miradas to test. Johnson's team would have been a major coup for Dodge, as they had been running GM cars since the team's inception and the team had just signed Darrell Waltrip away from DiGard Motorsports to drive for them (Waltrip having won 22 races in GM cars prior to this).
