Fusing unlocks an extra upgrade stage, allowing you to upgrade each category one more time.

The higher the tier the more fusion points you need, you can also fuse before the max stage is reached.

A single car will provide fusion points depending on how upgraded it is or how rare the car is (e.g. found in crates or bought with gold).

To upgrade a car by one star you need to have enough of:

Cars - these need to be cars you are happy to lose, fusing a car cannot be undone, and any augments you have installed will be lost! Make sure you lock cars you don't want to lose.

Manufacturer Fusion Credits - can be won from PvE events only, and need to match the manufacturer of the car you are upgrading.

Please note not all PvE events will include fusion credits, please take a look at the prizes before entering to see if fusion credits are included.

They will also be manufacturer based, depending on the PvE event chosen e.g. Ford event will mean Ford fusion credits only.

Boss cars can NOT be fused
