Continue ShoppingUpgrading cars in Forza Horizon 6 is one of the most satisfying ways to see your driving skills shine. Whether you want to dominate races, tackle mountain passes, or drift through city streets, knowing how to enhance your vehicle's performance is key.
You can upgrade your cars at any Player House or Festival Site. Open the main menu, navigate to the Cars tab, and select Upgrades & Tuning. From here, you have three main options: Auto-Upgrades, Custom Upgrades, or applying community-built setups via the Tune Browser.
You don't even need to be at a house to use community tunes—just open the pause menu and browse for setups to instantly install race-ready configurations.

If you want a quick boost without fuss, Auto-Upgrade is your friend. Select your target class, like B, A, or S1, and the game automatically chooses the best parts to maximize your Performance Index (PI). It's fast, effective, and perfect for players who just want to jump straight into competition.
For players who love fine-tuning, Custom Upgrades let you modify each part manually:
If building from scratch isn't your style, the Tune Browser is a lifesaver. Browse highly rated community tunes and instantly apply setups for street racing, drift, or off-road adventures. It's a simple way to get race-ready without trial and error.
