This GT7 tune breaks down the exact parts and car settings needed to make the Plymouth Superbird 70 Best Top Speed Tune in Gran Turismo 7.

Vehicle History

The Plymouth Superbird is a highly modified Dodge Charger Daytona. It was a short-lived factory follow-up design of the 1969 Charger.

The most iconic features of the Plymouth Superbird are the huge protruding rear wing and the infamous horn which mimics the Road Runner cartoon character.

The Superbird comes equipped with a 7.0L Hemi engine producing 425HP. It can hit 60MPH in 5.5 seconds.

Moreover, there were originally 1,920 Superbird cars built but most of them sat in factories unsold because people preferred the standard Dodge Daytona.

Consequentially, many of the unsold Superbirds were converted into standard Daytonas and sold on.
