Unicorn Cars are a series of non-purchaseable cars that appear in Forza Motorsport 2, Forza Motorsport 3, Forza Motorsport 4 and Forza Horizon. Unicorn cars were primarily obtained as reward gifts by Turn 10 Studios for successfully completing certain Rivals mode challenges. Some cars are also included as high tier rewards in the Forza Rewards loyalty program. It is also possible for players to gift them to other players, provided they have obtained a Unicorn car beforehand.
