Back in 2011 Hot Wheels produced the MINI CHALLENGE in Blue, Chili Red, and White. Then in late 2012 they followed those up with one in yellow with the same graphics as the previous three colors. For 2014 Hot Wheels released the MINI CHALLENGE in orange. This model can only be found in the multi-car gift pack. See other Hot Wheels and other die-cast MINIs.
