Crew Chief for Project Cars is a race engineer for Project Cars that contains more accurate and detailed radio messages than the built-in race engineer. It knows many of the AI drivers’ names which will be included in messages where appropriate, and can also be extended to include real drivers’ names. It’s a spotter and will tell you when there’s a car alongside. It runs in the background and continues to play messages even when the screen is off or if another application is being used.

You can request updates from the race engineer via voice from time to time.
