Classic American Muscle

"Get behind the wheel of Detroit metal in this classic blast from the past."

- In-game description.

Classic American Muscle is a racing series in the Professional racing career. Players can unlock the series by collecting 34 trophies in Supercar Masters Series. In this series, players can participate in 42 events, separated into 17 tiers.

There are three cars from which the player can choose, all being 1960s or 1970s versions of American muscle cars featured in the Pro/Am career section. Throughout the series, players can earn up to R$48,000 and 48 in bonuses upon reaching 100% completion of the series, however, as the Shelby '67 Cobra GT500 can only be acquired through, the player will have to spend some  in order to achieve 100% completion.

Tier 17.3 and 95% completion can be reached without upgrades.

Two bonus series have been added for Classic American Muscle, neither of which seem linked to the main series, and both feature only one car. Firstly, GT4 Renegades arrived in the Porsche Cayman GT4 update (3.1.0) and secondly, Renault's Global Passion was added via the Renault update (3.3.0) and features the Renault DeZir Concept. The next series after this is Accolade Open.
